CALIFORNIA FIRE CODE, CALIFORNIA BUILDING CODE, CALIFORNIA RESIDENTIAL
CODE, CALIFORNIA ELECTRICAL CODE, CALIFORNIA PLUMBING CODE, CALIFORNIA
MECHANICAL CODE, CALIFORNIA EXISTING BUILDING CODE, AND CALIFORNIA
GREEN BUILDING CODE, AS SET FORTH IN THE 2022 CALIFORNIA BUILDING
STANDARDS CODE AND THE INTERNATIONAL SWIMMING POOL AND SPA CODE, AND
INTERNATIONAL PROPERTY MAINTENANCE CODE
A. General Findings. The Dublin City Council makes the following general findings regarding
local climatic, geologic, and topographical conditions, which the City Council finds
necessitates the local modifications to the California Building Standards Code set forth below:
1. Local climatic conditions include a low amount of average yearly rainfall, which tends to be
concentrated from October through April. From May through September, a dry period
occurs where daily temperatures remain high and there is little measurable precipitation.
In addition, the local climate frequently includes high winds which sweep down through the
valley. As a result of the high summer temperatures, average load demand and peak load
demand of energy used in Dublin are important factors impacting public safety and creating
the potential for adverse economic impacts due to power outages or power reductions (i.e.
“brownouts”). As a result of the low precipitation, the area is subject to occasional drought.
In developed areas of the City, fires can occur in buildings, rubbish, automobiles, and grass
fires on vacant lots. In the undeveloped areas of the City, there is a risk of large brush and
grass fires. If a fire occurs in either a developed or undeveloped area of the City, the local
dry conditions combined with high winds, creates the risk of a potential fire storm.
In addition, local residential development is occurring in previously undeveloped areas
adjacent to wildfire hazard areas. These new developments increase the chance of fire
while simultaneously being located further from fire stations, delaying critical response
times. This potential problem can be mitigated by requiring initial fire control through the
installation of automatic fire protection systems.
2. Local geologic conditions include a risk of earthquake. A number of earthquake faults are
located either within or in close proximity to the City. Those with the most direct and
potentially destructive impact are the San Andreas, Calaveras, Hayward, Greenville and
Concord-Green Valley Faults. History of earthquake activity indicates that there is a
likelihood of a major earthquake in the area. The largest recorded earthquake in this
immediate area occurred on the San Andreas Fault on October 17, 1989, a 7.1 magnitude.
This area had a sequence of earthquakes on the Greenville Fault in January and February
of 1980; these earthquakes had a magnitude of 5.5 to 5.9 on the Richter Scale and in July
2019 the Greenville Fault had an earthquake of 4.3. The U.S. Geological Survey (USGS)
has identified a 72% probability of a major (6.7 or larger) earthquake occurring in the region
within the next 20 years (Source – USGS UCERF3 report). Recent earthquake damage
studies, including the 1994 Northridge earthquake, have indicated the lack of adequate
Page 2 of 56
design and detailing as a contributing factor to damages that reduced the protection of the
life-safety of building occupants.
In the event of an earthquake, damage to structures can be expected. In residential and
commercial areas, this could include significant damage or collapse of buildings.
Secondary impacts could include ruptured electric or gas connections and/or breaks in
water distribution lines. The potential for a major seismic event would create a City-wide
demand for emergency response and fire protection service which would exceed staff
response capacity. This potential problem can be mitigated by requiring initial fire control
through the installation of automatic fire protection systems.
3. Local topographical conditions include hills on the western and eastern boarders and flat
area in the center of the City. Interstate 680 divides the City into two sections, and
circulation between areas of the City rely on freeway overpasses. In addition, local traffic
must also pass over railroad tracks, creeks, and bridges (to cross arroyos).
During peak a.m. and p.m. traffic periods, the City experiences heavy traffic congestion at
key intersections, and near many freeway on-ramp and off-ramps. In the event of an
accident or emergency at one of these key intersections, bridges, or other circulation
corridors, sections of the City could become isolated and response times increased beyond
ideal levels. Again, this potential problem can be mitigated by requiring initial fire control
through the installation of automatic fire protection systems.
4. Based on the local climatic, geologic, and topographical conditions outlined above, there
is a real risk that emergency response could be significantly delayed in the event of an
accident or emergency. Therefore, it is necessary to address this problem through the
requirement of additional mitigation measures to: (i) prevent the chance of accident or
injury by requiring standards more stringent than required by the current codes; and (ii)
requiring additional built-in automatic fire protection systems which will provide for early
detection and initial fire control.
5. The burning of fossil fuels used to heat structures, heat water for cooking, and for other
uses is a significant contributor to greenhouse gas emissions and climate change.
Combustion of natural gas and petroleum products for heating and cooking needs emit
carbon dioxide, methane, and nitrous oxide. Emissions from natural gas consumption
represented 46% of the total annual U.S. energy related CO2 emissions in 2021. (See U.S.
Energy Information Administration, “Where Greenhouse Gases Come From”, 2021.)
Scientists attribute the global warming trend observed since the mid-20th century to the
human expansion of the ‘greenhouse effect’ warming that results when the atmosphere
traps heat radiating from Earth towards space. Long lived gasses such as carbon dioxide
can persist in the atmosphere for more than 100 years, even with efforts to reduce
emissions today. Nitrous oxide, carbon dioxide, and methane are gases that contribute to
the greenhouse gas effect. (See NASA, Causes of Climate Change, as of November 25,
2020.)
Global climate change imposes substantial and local impacts and risks on the San
Francisco Bay Area, and thus the City of Dublin, including rising temperatures, changing
precipitation patterns and amounts, sea level rise, flooding, drought, and wildfire, A general
Page 3 of 56
summary of climate risks facing the San Francisco Bay Area and the City of Dublin are as
follows:
• Increased temperatures and extreme heat events. The Bay Area is expected to
see an increase in average annual temperature of 2.7°F by 2050, and 3.5°F to 11°F
by 2100.
• Reduction in the Quality and Supply of Water in the Sierra Snowpack. If heat-
trapping emissions continue unabated, more precipitation will fall as rain instead of
snow, and the snow that does fall will melt earlier, reducing the Sierra Nevada spring
snowpack by as much as 70% to 90%. This can lead to challenges in securing
adequate water supplies. It can also lead to a potential reduction in hydropower.
• Changes in Rainfall Intensity. By mid-century, more precipitation is projected to
occur in winter in the form of less frequent but larger events. Most climate models
predict drying trends across the State by 2100.
• Increased Risk of Large Wildfires. A hotter, drier climate could promote up to 90%
more Northern California fires by the end of the century by drying out and increasing
the flammability of forest vegetation.
• Exacerbation of Air Quality Problems. If temperatures rise to the medium warming
range, there could be 75% to 85% more days with weather conducive to ozone
formation, relative to today’s conditions. This is more than twice the increase expected
if rising temperatures remain in the lower warming range. This increase in air quality
problems could result in an increase in asthma and other health-related problems. The
average air quality index in Dublin has consistently worsened over time and is lower
than the State and national averages; it also worsens during extreme heat and wildfire
events, As the air quality index increases, and increasingly large percentage of the
Dublin population is likely to experience increasingly adverse health effects.
All-electric construction has a significant positive effect on energy resource efficiency,
waste and pollution generation, and the health and productivity of building occupants
over the life of the building. The City of Dublin has a dry, hot period of at least five
months each year. As a result of the high temperatures, average load demand and peak
load demand of energy used in Dublin are important factors impacting public safety and
creating the potential for adverse economic impacts due to power outages or power
reductions (i.e. “brownouts”). Reduction of total and peak energy use because of
incremental conservation measures required by this ordinance will have local benefits in
the additional available system energy capacity. Furthermore, the reduction of
greenhouse gas emissions from all-electric buildings will help mitigate climate change
and its negative effects such as extreme heat events, droughts, intense storms, and
flooding, thus making these amendments reasonably necessary because of local
climactic reasons.
6. The San Francisco Bay area region is densely populated and located in an area of high
seismic activities. Concern for fire-life safety associated with gas appliances and
associated piping located in the ground and in buildings increases with the risk of
Page 4 of 56
explosion or fire if there is a structural failure due to a seismic event considering the
increasing number of buildings in the region.
The risk of natural gas infrastructure and pipeline explosions and fires are magnified in
cases of major earthquakes, for example, the 2010 San Bruno pipeline explosion.
Severe seismic events could disrupt communications, damage gas mains, and place
increased demands on the dispersed resources of the Fire Department necessary for the
life safety needs of the community Eliminating gas infrastructure in future construction
will also reduce the risks of fires and explosions, particularly after seismic events, which
will further save the City money by reducing disaster response and recovery costs. The
elimination of gas infrastructure in future construction will reduce risk of geologic risk via
natural gas infrastructure, making these amendments necessary because of local
geologic/ seismic reasons.
B. Specific Findings: The Dublin City Council makes the following specific findings, which, in
addition to the general findings regarding local climatic, geologic, and topographical
conditions set forth above, the City Council finds necessitate the local modifications to the
California Building Standards Code set forth below:
1. California Fire Code.
5.08.110 Chapter 2 Definitions-Amended.
Chapter 2 is amended by adding the following definitions to Section 202:
Section 202 General Definitions.
City Council shall mean the governing body of the City of Dublin.
City Manager shall mean the City Manager of the City of Dublin or his or her designee.
Fire Trail means a graded firebreak of sufficient width, surface, and design to provide
access for personnel and equipment to suppress and to assist in preventing a surface
extension of fires.
Fuel break means a wide strip or block of land on which the vegetation has been
permanently modified to a low volume fuel type so that fires burning into it can be more
readily controlled.
FINDING: These modifications are necessary to adopt the most current State standard
and to clarify specific areas of the code. In addition, these modifications will
make Chapter 5.08 consistent with Chapters 7.28, 7.32 and 7.34 of the Dublin
Municipal code. Definitions clarify the title of Fire Chief and City Council as
specific to the City of Dublin. These modifications will provide guidelines for
Fire Department access locations and roadway preparation. The
modifications also provide specific language to insure adequate access to fire
hydrants and fire appliances.
Page 5 of 56
5.08.120 Section 503.2.9 Specifications-Added.
Section 503.2.9 is added to read as follows:
503.2.9 Fire and Emergency Access Roads approved for construction sites shall be
designed to meet the requirements of Section 503.2. The access shall be approved by the
Fire Department prior to commencement of combustible storage or vertical combustible
construction on the site.
FINDING: This modification is necessary to adopt the most current State standard and
to clarify specific areas of the code. In addition, these modifications will make
Chapter 5.08 consistent with Chapters 7.28, 7.32 and 7.34 of the Dublin
Municipal code. These modifications will provide guidelines for Fire
Department access locations and roadway preparation. The modifications
also provide specific language to insure adequate access to fire hydrants and
fire appliances.

2. California Building Code.
7.32.120 Section 202, Chapter 2, Definitions of Substantial Damage and Substantial
Improvement – Added.
The definitions of “Substantial Damage” and “Substantial Improvement” in Section 202 of the
State Code are amended to read as follows:
Substantial Damage. Damage of any origin sustained by a structure whereby the cost of
restoring the structure to its before-damaged condition would equal or exceed 50 percent of the
market value of the structure before the damage occurred. The term also includes flood-related
damage sustained by a structure on two separate occasions during a 10-year period for which
the cost of repairs at the time of each such flood event, on average, equals or exceeds 25
percent of the market value of the structure before the damage occurred.
Substantial Improvement. Any one or more or any combination of repair,
reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure
taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent
of the market value of the structure before the improvement or repair is started. For each
building or structure, the 10-year period begins on the date of the first permit issued for
improvement or repair of that building or structure subsequent to January 1, 2023. If the
structure has sustained substantial damage, any repairs are considered substantial
improvement regardless of the actual repair work performed. The term does not, however,
included either:
1. Any project for improvement of a building required to correct existing health, sanitary
or safety code violations identified by the building official and that are the minimum
necessary to assure safe living conditions.
2. Any alteration of a historic structure provided that the alteration will not preclude the
structure’s continued designation as a historic structure.
FINDINGS The amendment is needed due to local climatic and topographical conditions.
This modification is necessary because the City of Dublin is a densely
populated area having buildings and structures constructed near and within
flood prone areas. The City codes require a definition for Substantial
Damage and Substantial Improvement that includes repetitive lossand
repetitive flood damage. Local climatic and topographical conditions
include a average yearly rainfall, which tends to be concentrated from
October to April.

FINDING: The amendment is needed due to local climatic and topographical conditions.
These modifications are necessary because the City of Dublin has a dry
period of at least five months each year. Additionally, the area is subject to
occasional drought. Because of dryness, a rapidly burning grass fire or
exterior building fire can quickly transfer to other buildings. These
modifications are consistent with the Fire Authority having jurisdiction.
7.32.190 Section 1505.1, Chapter 15, Fire Classification-Amended.

shall conform to the requirements as set forth in Roofing Area 1.
* Editor's Note: Figure 15-1 is on file in the office of the City Clerk.
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary because the City of Dublin has a dry period
of at least five months each year. Additionally, The area is subject to
occasional drought. Because of dryness, a rapidly burning grass fire or
exterior building fire can quickly transfer to other buildings. These
modifications are consistent with the Fire Authority having jurisdiction.
7.32.200 Table 1607.1, Chapter 16, Minimum Uniformly Distributed Live Loads, Lo, and
Minimum Concentrated Live Loads -Amended.
Table 1607.1 is amended by adding a new Footnote e to read:
e. Bridges for vehicular traffic shall be designed for H20 loading as designated by the
American Association of State Highway Officials.
FINDING: The amendment is needed due to local geological, climatic and topographical
conditions.
This modification was necessary because bridges were not addressed by the
Building Code. Additionally due to the City’s terrain a number of bridges and
overpasses may be required.
7.32.210 Section 1705.3 Exception 1, Chapter 17, Concrete Construction – Amended.
Section, 1705.3 Exception 1 is amended to read:
1. Isolated spread concrete footings of buildings three stories or less above grade plane
that are fully supported on earth or rock, where the structural design of the footing is based
Page 17 of 56
on a specified compressive strength, f’c, no greater than 2,500 pounds per square inch
(psi) (17.2 Mpa) regardless of the compressive strength specified in the construction
documents or used in the footing construction.
FINDINGS: The amendment is needed due to local geological conditions.
Results from studies after the 1994 Northridge earthquake indicated that a
lot of the damage was attributable to the lack of quality control during
construction and therefore needs to be incorporated into the Code. Revise
CBC Section 1705.3 exception No. 1 to allow special inspection not to be
required for isolated spread footings where the structural design of the
footing is based on a specified compressive strength, f’c no greater than
2,500 psi.
7.32.220 Section 1905.1.7, Chapter 19, ACI 318, Section 14.1.4-Amended.
Section 1905.1.7, Delete ACI 318, Section 14.1.4 and replace with the following:
14.1.4 - Plain concrete in structures assigned to Seismic Design Category C, D, E or F.
14.1.4.1- Structures assigned to Seismic Design Category C, D, E or F shall not have
elements of structural plain concrete, except as follows:
(a) Isolated footings of plain concrete supporting pedestals or columns are permitted,
provided the projection of the footing beyond the face of the supported member does
not exceed the footing thickness.
Exception:
In detached one- and two-family dwelling three stories or less in height, the
projection of the footing beyond the face of the supported member is permitted to
exceed the footing thickness.
(b) Plain concrete footing supporting walls are permitted, provided the footings have at
least two continuous longitudinal reinforcing bars. Bars shall not be smaller than No.
4 and shall have a total area of not less than 0.002 times the gross cross-sectional
area of the footing. A minimum of one bar shall be provided at the top and bottom of
the footing. Continuity of reinforcement shall be provided at corners and
intersections.
Exception:
In detached one- and two-family dwellings three stories or less in height and
constructed with stud bearing walls, plain concrete footings with at least two
continuous longitudinal reinforcing bars not smaller than No. 4 are permitted to
have a total area of less than 0.002 times the gross cross –sectional area of the
footing.
FINDINGS: The amendment is needed due to local geological, climatic and topographical
conditions.
Page 18 of 56
This amendment addresses the problem of poor performance of plain or
under reinforced concrete footings during a seismic event. This amendment
reflects the recommendations by the Structural Engineers Association of
Southern California (SEAOSC) and the Los Angeles City Joint Task Force that
investigated the poor performance of plain and under-reinforced concrete
footings observed in the 1994 Northridge earthquake.
The San Francisco Bay area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological Survey
and California Division of Mines and Geology. Recent earthquake activities,
including the 1989 Loma Prieta earthquake, have indicated the lack of
adequate design and detailing as a contributing factor to damages that
reduced the protection of the life-safety of building occupants. The City of
Dublin is a densely populated area having buildings constructed near
potentially active faults. The Association of Bay Area Governments (ABAG)
roughly estimates the probability of a serious earthquake along the Hayward
Fault as one-in-four in the next 20 years, while the USGS predict the
probability of a powerful quake in the next 20 years at 72%. The proposed
modification to ensure that the design of slender wall must satisfy both
strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of the
International Building Code.
7.32.230 Table 2308.6.1, Chapter 23, Wall Bracing Requirements–Amended.
Table 2308.6.1 is amended by adding new footnotes “f” and “g” to read:
f. Methods PBS, HPS, and SFB are not permitted in Seismic Design Category D
and E.
g. Methods GB, DWB and PCP are not permitted in Seismic Design Category E.
FINDINGS: The amendment is needed due to local geological conditions.
This amendment addresses the problem of poor performance of wall bracing
materials in high seismic areas. Shear walls sheathed with lath, plaster or
gypsum board are less ductile than plywood shear walls. The poor
performance of such shear walls in the 1994 Northridge earthquake was
investigated by the Structural Engineers Association of Southern California
(SEAOSC) with the Los Angels City Task Force and formed the basis for this
amendment. This amendment is consistent with shear wall restrictions by
the American Wood Council (Section 4.3.47 SDPWS) and ICC ESR-1338 for
Gypsum Board.
7.32.240 Section 2308.6.9, Attachment of Sheathing-Amended.
Section 2308.6.9, is amended by adding a second paragraph:
All braced wall panels shall extend to the roof sheathing and shall be attached to parallel
roof rafters or blocking above with framing clips (18 gauge minimum) spaced at maximum
Page 19 of 56
24 inches (6096 mm) on center with four 8d nails per leg (total eight 8d nails per clip).
Braced wall panels shall be laterally braced at each top corner and at maximum 24
inches (6096 mm) intervals along the top plate of discontinuous vertical framing.
FINDINGS: The amendment is needed due to local geological, climatic and topographical
conditions.
The San Francisco Bay area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological Survey
and California Division of Mines and Geology. Recent earthquake activities,
including the 1989 Loma Prieta earthquake, have indicated the lack of
adequate design and detailing as a contributing factor to damages that
reduced the protection of the life-safety of building occupants. The City of
Dublin is a densely populated area having buildings constructed near
potentially active faults. The Association of Bay Area Governments (ABAG)
roughly estimates the probability of a serious earthquake along the Hayward
Fault as one-in-four in the next 20 years, while the USGS predict the
probability of a powerful quake in the next 20 years at 72%. The proposed
modification to ensure that the design of slender wall must satisfy both
strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of the
International Building Code.
7.32.250 Section 3116.1, Chapter 31, Prohibited Installations-Added.
A new Section 3115.1 is added to read:
3116.1 Prohibited Installations. It shall be unlawful to install a wood burning fireplace
or wood burning appliance that is not one of the following:
1) Pellet-fueled wood heater,
2) EPA certified wood heater,
3) Fireplace certified by EPA
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary because fireplaces and wood stoves
generate 40 percent of the particulate matter in the Bay Area during the winter
months. Of greater concern are the fine particles, which can lodge deep in
the lungs causing permanent lung damage and increasing mortality. Burning
wood also generates carbon monoxide, nitrogen dioxide, volatile organic and
toxic air pollutants.
7.32.260 Section 3203, Chapter 32, Signs-Added.
A new Section 3203 is added to read:
3203 Signs. Signs when placed flat against the wall of a building shall not project
beyond the front property line more than 12 inches (305mm).
Page 20 of 56
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary due to the City of Dublin’s basic wind speed
requirement relating to the high winds described in Section A of these
Findings.
7.32.270 Section H101.2, Signs exempt from permits -Deleted.
Section H101.2 is deleted.
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary due to the City of Dublin’s basic wind speed
requirement relating to the high winds described in Section A of these
Findings.
7.32.280 Section 1010, Appendix Chapter 10, Building security – Added.
Appendix Chapter 10 is added to read:

State Code are amended to read as follows:
Substantial Damage. Damage of any origin sustained by a structure whereby the cost of
restoring the structure to its before-damaged condition would equal or exceed 50 percent of the
market value of the structure before the damage occurred. The term also includes flood-related
damage sustained by a structure on two separate occasions during a 10-year period for which
the cost of repairs at the time of each such flood event, on average, equals or exceeds 25
percent of the market value of the structure before the damage occurred.
Substantial Improvement. Any one or more or any combination of repair,
reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure
taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent
of the market value of the structure before the improvement or repair is started. For each
building or structure, the 10-year period begins on the date of the first permit issued for
improvement or repair of that building or structure subsequent to January 1, 2023. If the
structure has sustained substantial damage, any repairs are considered substantial
improvement regardless of the actual repair work performed. The term does not, however,
included either:
3. Any project for improvement of a building required to correct existing health, sanitary
or safety code violations identified by the building official and that are the minimum
necessary to assure safe living conditions.
Any alteration of a historic structure provided that the alteration will not preclude the structure’s
continued designation as a historic structure.

the gate. The slide bolt shall have a bolt diameter of three-eighths (3/8) inch and protrude at
least one and one-half (1 ½) inches into the receiving guide. The slide bolt shall be attached to
the gate with non-removable bolts. The slide bolt shall be mounted at a height that is not
accessible by reaching over the gate.
FINDINGS The amendment is needed due to local geological and topographical
conditions.
This modification is necessary due to the topographical nature of the City and
the easy access to freeways described in Section A of these Findings. In light
of said conditions, it is necessary to adopt these requirements to enhance
crime prevention. Additionally, this will bring the code into conformance with
the City of Dublin Police Department requirements.
7.34.210 Section R403.1.3, Chapter R4, Footing and stem wall reinforcing in Seismic
Design Categories D0, D1, D2. – Amended.
Section R403.1.3 is amended to read:
R403.1.3 Footing and stem wall reinforcing in Seismic Design Categories D0, D1,
D2. Concrete footings located in Seismic Design Categories D0, D1 and D2, as established in
Table R301.2, shall have minimum reinforcement of at least two continuous longitudinal
reinforcing bars, one top and one bottom and not smaller than No. 4 bars. Bottom reinforcement
shall be located a minimum of 3 inches (76 mm) clear from the bottom of the footing.
FINDINGS: The amendment is needed due to local geological, climatic and topographical
conditions.
The San Francisco Bay Area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological Survey
Page 37 of 56
and California Division of Mines and Geology. Recent earthquake activities,
including the 1989 Loma Prieta earthquake, have indicated the lack of
adequate design and detailing as a contributing factor to damages that
reduced the protection of the life-safety of building occupants. The City of
Dublin is a densely populated area having buildings constructed near
potentially active faults. The Association of Bay Area Governments (ABAG)
roughly estimates the probability of a serious earthquake along the Hayward
Fault as one-in-four in the next 20 years, while the USGS predict the
probability of a powerful quake in the next 20 years at 72%. The proposed
modification to ensure that the design of slender wall must satisfy both
strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of the
International Building Code.
7.34.220 Table R602.10.3(3), Chapter R6, Bracing Requirements – Amended.
Table R602.10.3(3) is amended by adding a new footnote “i” to read:
i. Methods PBS, HPS, SFB and CS-SFB are not permit in Seismic Design Categories D0,
D1, and D2 .
j. Methods GB, DWB and PCP are not permitted in Seismic Design Categories D0, D1,
and D2 where S1 is greater than or equal to 0.75.
Add the “i, j” footnote notation in the title of Table R602.10.3(3) to read:
TABLE R602.10.3(3)i, j
FINDINGS: The amendment is needed due to local geological, climatic and topographical
conditions.
The amendment addresses the problem of poor performance of these bracing
materials in high seismic areas to limit potential structural damage. Shear
walls sheathed with lath, plaster or gypsum board are less ductile than
plywood shear walls, The poor performance of such shear walls in the 1994
Northridge earthquake was investigated by the Structural Engineers
Association of Southern California (SEAOSC) and the Los Angeles City Task
Force and formed the basis for this amendment. This amendment is also
consistent with the design limitations for similar shear walls found in Table
2308.6.1 of the 2022 California Building Code.
7.34.230 Section R602.10.4.5, Chapter R6, Limits on methods GB and PCP –
Added.
A new Section R602.10.4.5 is added to read:
R602.10.4.5 Limits on methods GB and PCP. In Seismic Design Categories D0, D1,
and D2, Method GB is not permitted for use as intermittent braced wall panels, but gypsum
board is permitted to be installed when required by this Section to be placed on the opposite
Page 38 of 56
side of the studs from other types of braced wall panel sheathing. In Seismic Design Categories
D0, D1, and D2, the use of Method PCP is limited to one-story single-family dwellings and
accessory structures.
FINDINGS: The amendment is needed due to local geological, climatic and topographical
conditions.
This section deletes the use of gypsum board for lateral bracing. This deletion
is necessary because the City of Dublin is located in Seismic Zone D and E.
Gypsum wallboard has performed poorly during recent California seismic
events. The shear values for gypsum wallboard contained in the code are
based on mono-directional testing. In addition, this section limits the use of
portland cement plaster for lateral bracing to single story residential
buildings. This limitation is necessary because the City of Dublin is located
in Seismic Zone D and E. Exterior portland cement plaster has performed
poorly during recent California seismic events. The shear values for portland
cement stucco contained in the code are based on mono-directional testing.
It is appropriate to limit the use of this product until cyclic loading tests are
performed and evaluated.
The San Francisco Bay Area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological Survey
and California Division of Mines and Geology. Recent earthquake activities,
including the 1989 Loma Prieta earthquake, have indicated the lack of
adequate design and detailing as a contributing factor to damages that

strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of the
International Building Code.
7.34.240 Section R902, Chapter 9, Fire Classification-Amended.
Section R902.1 is amended to read:
R902.1 Roof covering materials. Roofs shall be covered with materials as set forth in
Sections R904 and R905. A minimum Class A, B or C roofing shall be installed in areas
as designated below or where the edge of the roof is less than 3 feet from a lot line.
Class A, B and C roofing required by this section to be listed shall be tested in
accordance with UL 790 or ASTM E 108.
1. Map of Fire Safe Roof Areas. Figure 15-1* is a map of Fire Safe Roof
areas. Said map may be amended from time to time by including areas which are
Page 39 of 56
annexed to the City within one of the two roofing areas. Said amendments may be
made by the Building Official after consultation, with the Chief of the Fire Department or their
designee having jurisdiction.
2. Roofing Area 1. Any new roof and any alteration, repair or replacement for
buildings housing R & U-1 occupancies in Roofing Area 1 shall use roof covering
material that conforms to Class B or better or shall be made of concrete, ferrous or
copper metal, clay, slate or similar non-combustible material.
3. Roofing Area 2. Any new roof for buildings using roof covering material
that conforms to Class C or better or shall be made of concrete, ferrous or copper metal,
clay, slate or similar non-combustible material.
* Editor's Note: Figure 15-1 is on file in the office of the City Clerk.
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary because the City of Dublin has a dry period
of at least five months each year. Additionally, The area is subject to
occasional drought. Because of dryness, a rapidly burning grass fire or
exterior building fire can quickly transfer to other buildings. These
modifications are consistent with the Fire Authority having jurisdiction.
7.34.150 Section R1001.1.2 Chapter 10, Prohibited Installations—Added.
A new Section R1001.1.2 is added to read:
R1001.1.2 Prohibited Installations. It shall be unlawful to install a new wood burning
fireplace or appliance that is not one of the following:
4) Pellet-fueled wood heater,
5) EPA certified wood heater,
6) Fireplace certified by EPA
FINDING: The amendment is needed due to local climatic and topographical conditions.
This modification was necessary because fireplaces and wood stoves
generate 40 percent of the particulate matter in the Bay Area during the winter
months. Of greater concern are the fine particles, which can lodge deep in
the lungs causing permanent lung damage and increasing mortality. Burning
wood also generates carbon monoxide, nitrogen dioxide, volatile organic and
toxic air pollutants.

4. California Electrical Code.
7.36.070 Section 210.53, Office receptacle outlets-Added.
Section 210.53 is added to read:
210.53 Office Receptacle Outlets. In office buildings or offices exceeding ten (10)
percent of the floor area of the major use, receptacle outlets shall be installed in all
permanent walls or partitions of each office so that no point along the floor line any wall
space is more than six (6) feet (1.83m) measured horizontally, from an outlet in that space
including any wall space two (2) feet (610 mm) or more in width and the wall space occupied
by sliding panels in exterior walls.
As used in the section a "wall space" shall be considered a wall unbroken along the
floor line by doorways, fireplaces and similar openings. Each wall space two (2) or more feet
(610 mm) wide shall be treated individually and separately from other wall spaces within the
room. A wall space shall be permitted to include two or more walls of a room (around
corners) where unbroken at the floor line.
As used in this section “office space” means an enclosed office space with hard walls.
Open office floor plans are not affected by this section.
Receptacle outlets shall, insofar as practicable be spaced equal distances apart.
Receptacle outlets in floors shall not be counted as part of the required number of receptacle
outlets unless located near the wall.
The receptacle outlets required by the section shall be in addition to any receptacle that
is part of any lighting fixture or appliance, located within cabinets or cupboards, or located
over five and one-half (5 ½) feet (1.68 m) above the floor.
FINDINGS: The amendment is needed due to local geological conditions.
This section requires additional receptacles. The City of Dublin is located in
a highly active Seismic Zone D and E. In Office Buildings without these
requirements extension codes are being used. Extension cords are not
afforded the same protection from damage as wiring raceways. Damage to
extension cords could occur in a seismic event, which increases the potential
for a fire.

5. California Plumbing Code.
7.40.080 Section 609.3, Chapter 6, Under Concrete Slab–Amended.
Section 609.3, first paragraph, is amended by replacing it to read:
Section 609.3 Water piping shall not be installed in or under a concrete floor slab within a
building without prior approval of the Building Official. When approved, such piping shall
be installed in accordance with the following requirements:
FINDINGS The amendment is needed due to local geological conditions.
This section eliminates water piping in or under concrete floor slabs within a
building. This amendment is necessary for the following reasons:
(1) Most of the surface soils in the City of Dublin are relatively young and
unconsolidated sedimentary materials formed from a wide variety of parent
materials. The varying chemical composition, degree of weathering and the
relatively acid environment have created soils of varying types, which are
particularly corrosive in nature.
(2) Much of the surface soil in the City of Dublin is highly expansive (i.e., shrink-
swell behavior) and have low bearing strength.
(3) There are two types of expansive soils in the area:
a. the organic silty clays which are the recent bay muds; and
b. the plastic silty clays which weather from the shale found in the hills
surrounding the City of Dublin
(4) The local climate is characterized by markedly delineated rainy and dry
seasons, which tend to maximize the expansive characteristics of soil.
(5) Some parts of the City of Dublin have hard water, which is corrosive to ferrous
pipe.
(6) The groundwater table is unusually high in many places.
(7) The City of Dublin is a highly active seismic area.

7.46.080 Section 202, Chapter 2, Definitions of Substantial Damage and Substantial
Improvement.
The definitions of “Substantial Damage” and “Substantial Improvement” in Section 202 of the
State Code are amended to read as follows:
Substantial Damage. Damage of any origin sustained by a structure whereby the cost of
restoring the structure to its before-damaged condition would equal or exceed 50 percent of the
market value of the structure before the damage occurred. The term also includes flood-related
damage sustained by a structure on two separate occasions during a 10-year period for which
the cost of repairs at the time of each such flood event, on average, equals or exceeds 25
percent of the market value of the structure before the damage occurred.
Substantial Improvement. Any one or more or any combination of repair,
reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure
taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent
of the market value of the structure before the improvement or repair is started. For each
building or structure, the 10-year period begins on the date of the first permit issued for
improvement or repair of that building or structure subsequent to January 1, 2023. If the
structure has sustained substantial damage, any repairs are considered substantial
improvement regardless of the actual repair work performed. The term does not, however,
included either:
1. Any project for improvement of a building required to correct existing health, sanitary
or safety code violations identified by the building official and that are the minimum
necessary to assure safe living conditions.
2. Any alteration of a historic structure provided that the alteration will not preclude the
structure’s continued designation as a historic structure.
FINDINGS The amendment is needed due to local climatic and topographical conditions.
This modification is necessary because the City of Dublin is a densely
populated area having buildings and structures constructed near and within
flood prone areas. The City codes require a definition for Substantial
Damage and Substantial Improvement that includes repetitive lose and
repetitive flood damage. Local climatic and topographical conditions
include a average yearly rainfall, which tends to be concentrated from
October to April.

8. California Green Building Code
7.94.050 Section 202, Chapter 2 Definitions – Amended.
The following definitions are hereby added to Section 202 of the State Code to read as follows:
ALL-ELECTRIC BUILDING. A building that contains no combustion equipment or plumbing for
combustion equipment within the building or building property lines, and instead uses electric
appliances for service.
COMMERCIAL FOOD HEAT-PROCESSING EQUIPMENT. Equipment used in a food
establishment for heat-processing food or utensils and that produces grease vapors, steam,
fumes, smoke, or odors that are required to be removed through a local exhaust ventilation
system, as defined in the California Mechanical Code.
COMBUSTION EQUIPMENT. Any equipment or appliance used for space heating, water
heating, cooking, clothes drying and/or lighting that uses fuel gas.
ELECTRIC HEATING APPLIANCE. A device that produces heat energy to create a warm
environment by the application of electric power to resistance elements, refrigerant
compressors, or dissimilar material junctions, as defined in the California Mechanical Code.
FUEL GAS. A gas that is natural, manufactured, liquefied petroleum, or a mixture of these.
FINDINGS The amendment is needed due to local climatic conditions.
All-electric construction has a significant positive effect on energy resource
efficiency, waste and pollution generation, and the health and productivity
of building occupants over the life of the building. The City of Dublin has a
dry, hot period of at least five months each year. As a result of the high
temperatures, average load demand and peak load demand of energy used
in Dublin are important factors impacting public safety and creating the
potential for adverse economic impacts due to power outages or power
reductions (i.e. “brownouts”). Reduction of total and peak energy use
because of incremental conservation measures required by this ordinance
will have local benefits in the additional available system energy capacity.
Furthermore, the reduction of greenhouse gas emissions from all-electric
buildings will help mitigate climate change and its negative effects such as
extreme heat events, droughts, intense storms, and flooding, thus making
these amendments reasonably necessary because of local climactic
reasons.
7.94.060 Section 4.106.4 Electric vehicle (EV) charging for new construction – Deleted
and Replaced.
Section 4.106.4 is deleted and replaced with Section A4.106.8 to read:
A4.106.8 Electric vehicle (EV) charging for new construction is adopted as mandatory at
the Tier 2 level.
Page 45 of 56
FINDINGS The amendment is needed due to local climatic, topographical and
environmental conditions.
This modification is necessary because the City of Dublin is a densely
populated area having buildings and structures constructed within heavily
traveled traffic corridors and highways (580 and 680), near and within flood
prone areas. This impacts the quality of the air, causes higher decibel noise
level, and increases the risk of rising sea or flood levels. The proposed
modification to increase the number of EV charging spaces will help to
address and significantly reduce local air and noise pollutions, greenhouse
gas emissions, and will improve the health and welfare of the City’s
residents, businesses and visitors and reduce the rise in sea or flood levels
that could put at risk the City’s homes, businesses and public facilities at
risk. Therefore, this amendment needs to be incorporated into the code to
assure that new buildings and structures and additions or alterations to
existing buildings or structures are designed and constructed in accordance
with the scope and objectives of the California Green Building Standards
Code.
7.94.070 Sections 4.106.5, 4.106.5.1, and 4.106.5.2 All Electric Buildings – Added.
Sections 4.106.5, 4.106.5.1, and 4.106.5.2 are added to read:
4.106.5 All-electric buildings. New construction buildings and qualifying alteration projects
shall comply with Section 4.106.5.1 or 4.106.5.2 so that they do not use combustion equipment
or are ready to accommodate installation of electric heating appliances.
4.106.5.1. New construction and qualifying alteration projects. All newly constructed
buildings shall be all-electric buildings. Qualifying alteration projects shall be limited to additions
or alterations that remove 50 percent or more of the existing exterior walls of a dwelling and
additions that increase the square footage of the structure by more than 50 percent.
The final determination whether a project meets the definition of a qualifying alteration project
shall be made by the Building Official
Exception:
If the applicant establishes that there is not an all-electric prescriptive compliance
pathway for the building under the California Building Energy Efficiency Standards,
and that the building is not able to achieve the performance compliance standard
applicable to the building under the Energy Efficiency Standards using
commercially available technology and an approved calculation method, then the
Building Official may grant a modification. The applicant shall comply with the
following and Section 4.106.5.2.
Inactive Fuel Gas Infrastructure may be extended to spaces that are anticipated to
qualify for the exceptions contained in this chapter. The inactive Fuel Gas
Infrastructure shall not be activated, have a meter installed, or otherwise used
unless the exemptions specified in this chapter have been confirmed as part of the
issuance of a building permit. If the Fuel Gas Infrastructure is no longer serving one
Page 46 of 56
of the exceptions contained in this chapter, it shall either be capped, otherwise
terminated, or removed by the entity previously entitled to the exemption, in a
manner pursuant to all applicable Codes.
The Building Official shall have the authority to approve alternative materials and methods of
construction as per the Dublin Municipal Code, Chapter 7.28.
4.106.5.2 Requirements for combustion equipment.
Where combustion equipment is allowed under subsection 4.106.5.1, the construction drawings
shall indicate electrical infrastructure and physical space accommodating the future installation
of an electrical heating appliance in the following ways, as certified by a registered design
professional or licensed electrical contractor:
1. Branch circuit wiring, electrically isolated and designed to serve all electrical heating
appliances in accordance with manufacturer requirements and the California Electrical
Code, including the appropriate voltage, phase, minimum amperage, and an electrical
receptacle or junction box within five feet of the appliance that is accessible with no
obstructions. Appropriately sized conduit may be installed in lieu of conductors; and
2. Labeling of both ends of the unused conductors or conduit shall be with “For Future
Electrical Appliance”; and
3. Reserved circuit breakers in the electrical panel for each branch circuit, appropriately
labeled (i.e. “Reserved for Future Electric Range”), and positioned on the opposite end of
the panel supply conductor connection; and
4. Connected subpanels, panelboards, switchboards, busbars, and transformers shall be
sized to serve the future electrical heating appliances. The electrical capacity
requirements shall be adjusted for demand factors in accordance with the California
Electric Code; and
5. Physical space for future electrical heating appliances, including equipment footprint, and
if needed a pathway reserved for routing of ductwork to heat pump evaporator(s), shall
be depicted on the construction drawings. The footprint necessary for future electrical
heating appliances may overlap with non-structural partitions and with the location of
currently designed combustion equipment.
FINDINGS The amendment is needed due to local climatic conditions.
All-electric construction has a significant positive effect on energy resource

Added.
A new Section 4.107.1 is added to read:
4.107.1 Future Access for Solar Systems. A minimum one-inch (25.4 mm) electrical
conduit shall be provided from the electrical service equipment to the solar zone as defined
by the California Energy Code, Title 24, Part 6, Section 110.10. Where a solar zone is not
required by the California Energy Code, the conduit location shall be subject to approval of
the Building Official.
Exception: Where solar is installed as part of the original construction and prior to first
occupancy.
FINDINGS The amendment is needed due to local climatic, topographical and
