No measurable additional costs.
DESCRIPTION: The uniform model construction codes are adopted and published by
the California Building Standards Commission and by the California Department of Housing and ~,
Community Development on a three-year cycle. The provisions of this ordinance shall take effect on
January 1, 1996 pursuant to Government Code section 36937 as an urgency ordinance. The urgency is
based on the fact that the State published and adopted the 1994 editions of the model codes on July 1,
1995. A 4/5 vote is required to adopt the ordinance as an urgency ordinance.
The uniform codes must be adopted by the City as published unless the City Council adopts a resolution
finding that changes or modifications are necessary due to local climatic; geological or topographical
conditions. A number of such changes or modifications were made by the Council when it adopted the
1991 uniform codes.

~_/
The proposed ordinance adopting the 1994 model codes contains most of the same changes which were .
included in the City's adoption of the 1991 codes, except as noted in the following paragraphs. Some f
previous changes have been eliminated because the 1994 codes have incorporated these changes. For
example, current State law (1994 codes) now requires all new roofs, including re-roofmg, to be a
minimum Class C fire-retardant roof. Therefore, the City's prior change requiring Class C roofs is no
longer required.

The proposed ordinance will streamline Chapters 7.28, 7.32, 7.40, 7.44 and 7.48 of the Dublin Municipal
Code which has many benefits for the City which include the following:
1. To ensure consistency with neighboring jurisdictions and the Bay Area.
2. To provide internally consistent, coherent and easier to use codes for City Staff.
3. To make it clearer for the public to review and to understand the uniform code
requirements.
The Rroposed ordinance does not adopt the Administration Chapters of the uniform codes which include
the permit fee tables, thus maintaining the City's current permit fees.
The provisions of the 1994 edition of the Uniform Building, Mechanical, Plumbing and Housing Code
have been reformatted into a "common code" format. The new format establishes a common format of
chapter designations for the three model codes published in the United States. A number of minor
changes to the Dublin Municipal Code are required as a result of the reformatting.
SUMMARY OF PROPOSED ORDINANCE:
1.
Therbe are 3f6thsecutio.~s of thBe .Mld~icCipadl Code that would be amended to refer to the new section e_-- __---.
num ers 0 e nl10rm Ul mg 0 e.
There are 2 sections of the Municipal Code that would be an referenced to an incorrect section of
the uniform code.
There are 12 sections of the Municipal Code that are in the new 1994 uniform code. These
Municipal Code sections are therefore no longer necessary.
There are 5 sections of the Municipal Code that would adopt the new uniform codes.
There is one section that coincides with State Law.
There are 13 new proposed changes to be added to the Dublin Municipal Code which are in
addition to changes carried over from 1991 (discussed in more detail below).

SUMMARY OF PROPOSED CHANGES TO THE DUBLIN MUNICIPAL CODE:
1. Section 22 (Section 7.32.260 of the Dublin Municipal Code) is modified to require an automatic
fIre-extinguishing system when of Type V construction (which is construction consisting of the
lowest degree of fire resistance, in other words, buildings constructed of wood frame
construction). and when floor area exceeds 3,000 square feet in all occupancies except Group R,
Division 1 and 3 (which are single-family residences and multi-family residences).
The potential impact to buildings within the City of Dublin would total five (5) existing buildings.
The existing Dublin Municipal Code requires automatic fire-extinguishing systems in buildings
having areas in excess of 5,000 square feet. This requirement would only be triggered in existing e-.
buildings where square footage is added to the building. All proposed new buildings with areas
greater than 3,000 square feet would be required to have an automatic fire-extinguishing system.
e'" 3.
.:"7.

2.
Section 23 (Section 7.32.260 of the Dublin Municipal Code) modifies the Uniform Building Code
to require an automatic fire-sprinkler system when any building except (private garages and utility
buildings) are located more than 1 'is miles from a fire station. This is an existing requirement of
the Dublin Municipal Code.
Section 25 (Section 7.32.270 of the Dublin Municipal Code) adds a requirement of a minimum of
one 1/2" diameter top and bottom reinforcement in all continuous foundations. This amendment is
necessary because the City of Dublin is within a very active seismic area (Seismic Zone 4) and
local soil conditions can be highly expansive clay soils. The Northridge earthquake provided
hundreds of examples of damage to plain concrete footings. This type of damage is extremely
expensive to repair, in contrast to the small expense of providing nominal footing reinforcement.
Footing reinforcement is also necessary to prevent damage due to pumping action caused by local
expansive soils which shrink and swell during seasonal drying and wetting conditions.
4.
Section 26 (Section 7.32.271 of the Dublin Municipal Code) modifies the Uniform Building Code
to require slab reinforcement. This modification is necessary due to the expansive soil conditions
and this is a typical minimum requirement by soil engineers in the City of Dublin in order to avoid
damage due to soil expansion and shrinkage.
..
5.
Section 27 (Section 7.32.272 of the Dublin Municipal Code) deletes the use of gypsum board for
lateral bracing. This deletion is necessary because the City of Dublin is located in Seismic Zone 4.
Gypsum wall~oard has performed poorly during recent California seismic events.
6.
Section 28 (Section 7.32.273 of the Dublin Municipal Code) limits the use of portland cement
plaster for lateral bracing to single story residential. This limitation is necessary because the City
of Dublin is located in Seismic Zone 4. Exterior portland cement plaster has performed poorly
during recent California seismic events.
Section 29 (Section 7.32.274 of the Dublin'Municipal Code) adds a new paragraph to require
upgrade of suspended ceiling systems for alteration and repair projects. This amendment is
necessary to mitigate a known seismic hazard in existing buildings due to the City of Dublin's
proximity to local active faults.
8.
Section 44 (Section 7.36.030 of the Dublin Municipal Code) limits the use ofNM and NMC
cables. The City of Dublin is located in the highly active seismic zone 4. Nonmetallic-sheathed
cable is not afforded the same protection from damage as wiring in a protective outer coating.
Damage to Nonmetallic-sheathed cable could occur in a seismic event which increases the
potential for a fire.
Section 50 (Section 7.40.105 of the Dublin Municipal Code) 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
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).
3. The local climate is characterized by markedly delineated rainy and dry seasons, which tend to
maximize the expansive characteristics of soil.
e' 4. Some parts of the City of Dublin have hard water, which is corrosive to ferrous pipe.
5. The groundwater table is unusually high in many places.
6. The City of Dublin is a highly active seismic area.
10.
Section 51 (Section 7.40.110 of the Dublin Municipal Code) requires backflow protection if
drainage piping serving fixtures is less than 12 inches above the next upstream manhole. This
requirements is necessary due to the fact that the City of Dublin topography includes mountainous
and foothill areas with intermittent steep slopes. Also, the City of Dublin is located'in a
seismically active area, which increases the likelihood of breakage of building sewers and laterals,
leading to an above average potential of sewage back-up into buildings without adequate
protection.
e"",
, '
11. Section 52 (Section 7.40.115 of the Dublin Municipal Code) adds a subsection regarding location
and termination of cleanouts. This subsection is necessary because the City of Dublin soils are
expansive in nature. These expansive soils create unstable conditions which increase the potential
_ of breaks in sewer laterals. To maintain health and sanitary services, it is necessary to gain access,
to periodically maintained public sanitary laterals. This is accomplished by the additional cleanout
as required above.
12. Section 53 (Section 7.40.120 of the Dublin Municipal Code) details cooling coil and comfort
cooling disposal and drain sizing. This amendment is required because the waste treatment
facilities serving the City of Dublin is operating at or near maximum capacity. The discharge of
treated waste water into San Francisco Bay is detrimental to its sensitive ecosystem.
Cooling coil and comfort cooling equipment condensate waste discharge does not contain
pollutants which require treatment before being discharged into storm sewers or the ground.
13.
Section 59 (Section 7.44.080 of the Dublin Municipal Code) amends the code to comply with
local sanitation district requirements regarding disposal for condensate for HV AC systems. The
waste water treatment facilities serving the City of Dublin is operating at or near maximum
capacity. The discharge of treated waste water into San Francisco Bay is detrimental to its
sensitive ecosystem.

..
904.2.8.1 Group R. Division I and 3 Occupancies. An automatic fire-extinguishing system
shall be installed where the total area exceeds 5.000 square feet (465m~1
FINDING: This section modifies the Uniform Building Code to require an automatic fire-
extinguishing system when of type V construction and the floor area exceeds 3,000 square feet in
all occupancies, except R. Division 1 and 3. 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 Dougherty Regional
Fire Authority requirements.
SECTION 23
Section 7.32.260 of the Dublin Municipal Code is amended to read:
tB 904.2.9 All Group A, B, E, H, I, & R-l & R-3 Occupancies. Automatic fire-extinguishing
systems shall be installed in all Groups A, B, E, H, I, & R-l & R-3 occupancies located more than 1 'is ..',',
miles from a fire station providing fire protection to that location. Said distance shall be measured in a
s~"aight line. For R-3 occupancies the sprinkler system may be a residential sprinkler system as set forth
in Item & of Section 3&.103 ~fUBC Standard 38 1. type NFPA 13.
17
Buildings containing portions which are required to have an automatic fIre extinguishing system
because of the number of stories shall have the automatic fIre extinguishing system installed throughout
.:, and area separation as set forth in Section 505(c).5.Qti shall not be considered as creating separate
,:.:.' buildings for the purpose of this section. '
When the specific use of a building is not known at the time of design and installation of the automatic
fIre-extinguishing system the design shall be based upon Ordinary Hazard Group ~2 as set forth in UBC
Standard ~ B.
Whenever an addition is made to an existing building automatic fire-extinguishing systems shall be
installed if the existing building plus the addition exceeds the area or height limitation set forth in this
section. Whenever the use of an existing building or portion thereof is changed in any manner so as to
require the installation of an automatic fIre-extinguishing system, said system shall be installed in that
portion of the building housing the new use.
FINDING: 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 Dougherty Regional Fire Authority
requirements.
SECTION 24
Section 7.32.270 of the Dublin Municipal Code is deleted.
."
Section 3803 is amended by adding a second exception to read:
Exception 2: Local alarms are acceptable for R 3 occupancies.
REASON: The change to the 1991 Uniform Building Code which was made by this section is no
longer necessary since it is now included in the 1994 Uniform Building Code Section
904.3.2
SECTION 25
Section 7.32.270 of the Dublin Municipal Code is added to read:
Section 7.32.270 Section 1806. Chapter 18. Footings.
7.32.270, Section 1806 is amended by adding the following at the end of the first paragraph:
A minimum of one top and one bottom continuous bars of 1/2" diameter reinforcing steel shall
L<; required in all continuous concrete or masom:y bearing foundations of Group R residential
occupancies.
FINDING: This section adds a requirement of a minimum of one 1/2" diameter top and bottom
reinforcement in all continuous foundations. This amendment is necessary because The City of
Dublin is within a very active seismic area (Seismic Zone 4) and local soil conditions can be highly
expansive (clay soil). The Northridge earthquake provided hundreds of examples of damage to
plain concrete footings. This type of damage is extremely expensive to repair, in contrast to the
. small expense of providing nominal footing reinforcement. Footing reinforcement is also
. ... necessary to prevent damage due to pumping action caused by local expansive soils which shrink
. and swell during seasonal drying and wetting conditions.

SECTION 26
Section 7.32.271 of the Dublin Municipal Code is added to read:
Section 7.32.271 Section 1924, Chapter 19, Minimum Slab Thickness.
Section 1924 is amended as follows:
e-
(a) General. The minimum thickness of concrete floor slabs supported directly on the ~ound
shall be not less than 3-1/2". The slab shall be reinforced with not less than six inches by six inches ten-
gauge wire mesh or an approved alternate installed at mid height of the slab.
FINDING: This section modifies the Uniform Building code to require slab reinforcement. This
modification is necessary due to the expansive soil conditions and this is a typical minimum
requirement by soil engineers in the City of Dublin in order to avoid damage due to soil expansion
and shrinkage.
SECTION 27
Section 7.32.272 of the Dublin Municipal Code is added to read:
Section 7.32.272 Section 2326.11.3, Chapter 23, Item 5 Deleted - Bracing.
Section 2326.11.3. Item 5 is deleted.
FINDING: 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 4. 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. It is appropriate to limit
the use of this product until cyclic loading testings are performed and evaluated.
e
SECTION 28
Section 7.32.273 of the Dublin Municipal Code is added to read:
Section 7.32.273 Section 2326.11.3. Chapter 23. Item 7, Amended Bracing.
Section 2326.11.3 Item 7 is amended as follows:
Portland cement plaster on studs spaced 16 inches on center installed in accordance with Table
No. 47-1. Limited to si~gle story R-3 and U-l occupancies.
FINDING: This section limits the use of portland cement plaster for lateral bracing to single
story residential. This limitation is necessary because the City of Dublin is located in Seismic Zone
4. 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 testings are performed
and evaluated.
SECTION 29

Section 3403.2 is amended by adding the following paragraph at the end ofthe Section folloWing
.- exceptions.
When a permit is issued for alterations or repairs. the existing sus.pended ceiling system within
the area of alteration or repair shall comply with the lateral design requirements ofUBC Standard 25-2
Part III.
FINDING: This section adds a new paragraph to require upgrade of suspended ceiling systems
for alteration and repair projects. This amendment is necessary to mitigate a known seismic
hazard in existing buildings due to the City of Dublin's proximity to local active faults.
SECTION 30

SECTION 50
Section 7.40.105 of the Dublin Municipal Code is added to read:
Section 7.40.105 Section 609.3, Chapter 6. Water Piping in Slab Floors.
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:
FINDING: This section eliminates water piping in or under concrete floor slabs within a building.
This amendment is necessary for the following reasons:
1. Most ofthe 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 ofthe surface soil in the City of Dublin is highly expansive (i.e., shrink-swell
behavior) and have low bearing strength.
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.
3. The local climate is characterized by markedly delineated rainy and dry seasons, which
tend to maximize the expansive characteristics of soil.
4. Some parts of the City of Dublin have hard water. which is corrosive to ferrous pipe.
28
5. The groundwater table is unusually high in many places.
6. The City of Dublin is a highly active seismic area.

SECTION 51
Section 7.40.110 of the Dublin Municipal Code is added to read:
Section 7.40.110 Section 710.1, Chapter 7, Backwater Valves.
Section 710.1 is amended to read:
Section 710.1 Draina~e pipin~ servin~ fixtures which have flood level rims less than twelve (12)
inches (304.8mm) above the elevation of the next upstream manhole and/or flushin~ inlet cover at the
public or private sewer system servin~ such draina~e pipin~ shall be protected from backflow of sewa~e
by installin~ an approved type backwater valve. Fixtures above such elevation shall not dischar~e
throu~h the backwater valve. unless first approved by the Buildin~ Official.
FINDING: This section requires backflow protection if drainage piping serving fixtures is less
than 12 inches above the next upstream manhole. This requirement is necessary due to the fact
that the City of Dublin topography includes mountainous and foothill areas with intermittent
steep slopes. Also. the City of Dublin is located in a seismically active area, which increases the
likelihood of breakage of building sewers and laterals, leading to an above average potential of
sewage back-up into buildings without adequate protection.
SECTION 52
.-:.
Section 7.40.115 of the Dublin Municipal Code is added to read:
Section 7.40.115 Section 719.7. Chapter 7, Cleanouts.
Section 719.7 is amended by adding subsection 7 to read:
Section 719.7 Cleanouts shall be installed at the property line where the private sewer system
connects to the publicly-maintained sanitary sewer lateral. All such line cleanouts shall be extended to
grade with materials and accordin~ to specifications approved by the Buildin~ Official and terminate
within a concrete box.
FINDING: This section adds a subsection regarding location and termination of cleanouts. This
subsection is necessary because the City of Dublin soils are expansive in nature. These expansive
soils create unstable conditions which increase the potential of breaks in sewer laterals. To
maintain health and sanitary services, it is necessary to gain access, to periodically maintained
public sanitary laterals. This is accomplished by the additional clean out as required above.
SECTION 53
Section 7.40.120 of the Dublin Municipal Code is amended to read:

be used for the storage or holding of food or drinks shall be collected and discharged to a storm sewer or
other approved points of disposal acceptable to the Building Official.
Termination of such drains shall be made by an air break. Condensate drain lines in sizes 11/4" and
larger shall be assembled using approved drainage pipe and fittings. Condensate waste water shall not
drain over or upon a public way. sidewalk. pedestrian ramp or the like. Condensate drains within the
interior of a building shall not be connected to the building roof drain or overflow piping systems. The
waste pipe shall have a slope of not less than 1/8 inch per foot and shall be of approved corrosion-
resistant material not smaller than the outlet size as required below for air-cooling coils or condensing
fuel-burning appliances. respectfully.
Condensate wastes pipes from air-cooling coils shall be sized in accordance with equipment capacity as
follows:
Equipment Capacity
Up to 20 tons of refrigeration
21 to 40 tons of refrigeration
41 to 90 tons of refrigeration
91 to 125 tons of refrigeration
126 to 250 tons of refrigeration
Minimum
Condensate
Pipe Diameter
3/4 inch
1 inch
1 1/4 inch
1 1/2 inch

The size of condensate waste pipes mav be for one unit or a combination of units, or as recommended by
the manufacturer. The capacity of waste pipes assumes a 1/8 inch-per-foot slope. with the pipe running
three-quarters full.
.
Condensate drain sizing for other slopes or other conditions shall be approved by the Building Official.
FINDING: This section details condensate disposal and drain sizing. This amendment is required
because the waste treatment facilities serving the City of Dublin is operating at or near maximum
capacity. The discharge of treated water into San Francisco Bay is detrimental to its sensitive
ecosystem.
C'ooling coil and comfort cooling equipment condensate waste discharge does not contain
pollutants which require treatment before being discharged into storm sewers or the ground.

The sections listed below are sections of Ordinance -95
Sections 1.3.4.7,8.9.10. 13. 14,32.33.34.35,36.37.38.39.40.41.47.48,49.54.55.56.58.61.62,
63. 64. 65. 66. 67. 68. 69 and 70 have been reformatted to new section numbers.
Sections 2. 11 referenced incorrect reference.
Sections 5. 12. 15, 16. 17. 18. 19.21.24. 31.42 and 43 are in the new 1994 uniform codes.
Sections 6. 44. 46. 57 and 60 adopts the uniform codes.
Section 20 coincides with State law.
Section 22 modifies the Uniform Building Code to require an automatic fire-extinguishing system when
. of type V construction and the floor area exceeds 3,000 square feet in all occupancies, except R,
Division 1 and 3.
Section 23 modifies the Uniform Building Code to require an automatic fire-sprinkler system when Group
A, B, E, H, I and R-l and R-3 occupancies are located more than 1 'is miles from a fire station.
Section 24, adds a' requirement of a minimum of one 1/2" diameter top and bottom reinforcement in all .'~
continuous foundations. This amendment is necessary because the City of Dublin is within a very
active seismic area (Seismic Zone 4) and local soil conditions can be highly expansive clay soils.
The Northridge earthquake provided hundreds of examples of damage to plain concrete footings.
This type of damage is extremely expensive to repair, in contrast to the small expense of providing
nominal footing reinforcement. Footing reinforcement is also necessary to prevent damage due to
pumping action caused by local expansive soils which shrink and swell during seasonal drying and
wetting conditions.
Section 25, modifies the Uniform Building Code to require slab reinforcement. This modification is
necessary due to the expansive soil conditions and this is a typical minimum requirement by soil
engineers in the City of Dublin in order to avoid damage due to soil expansion and shrinkage.
Section 26, deletes the use of gypsum board for lateral bracing. This deletion is necessary because the
City of Dublin is located in Seismic Zone 4. 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. It is appropriate to limit the use of this product until cyclic
loading testing are performed and evaluated.
Section 27, limits the use of portland cement plaster for lateral bracing to single story residential. This
limitation is necessary because the City of Dublin is located in Seismic Zone 4. 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 testing are performed and
evaluated.
Section 28, adds a new paragraph to require upgrade of suspended ceiling systems for alteration and repair
projects. This amendment is necessary to mitigate a known seismic hazard in existing buildings
due to the City of Dublin's proximity to local active faults.

Section 44, limits the use ofNM and NMC cables. The City of Dublin is located in the highly active
seismic zone 4. Nonmetallic-sheathed cable is not afforded the same protection from damage as
wiring in raceways. Damage to Nonmetallic-sheathed cable could occur in a seismic event which
increases the potential for a frre.

Section 49, 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.
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.
3. The local climate is characterized by markedly delineated rainy and dry seasons, which tend to
maximize the expansive characteristics of soil.

4. Some parts of the City of Dublin have hard water, which is corrosive to ferrous pipe.
5. The groundwater table is unusually high in many places.
6. The City of Dublin is a highly active seismic area.
Section 50, requires backflow protection if drainage piping serving fixtures is less than 12 inches above
the next upstream manhole. This requirements is necessary due to the fact that the City of Dublin
topography includes mountainous and foothill areas with intermittent steep slopes. Also, the City of
Dublin is located in a seismically active area, which increases the likelihood of breakage of building
sewers and laterals, leading to an above average potential of sewage back-up into buildings without
adequate protection.
Section 51, adds a subsection regarding location and termination of cleanouts. This subsection is
necessary because the City of Dublin soils are expansive in nature. These expansive soils create unstable
conditions which increase the potential of breaks in sewer laterals. To maintain health and sanitary
services, it is necessary to gain access, to periodically maintained public sanitary laterals. This is
accomplished by the additional cleanout as required above.
Section 52, details condensate disposal and drain sizing. This amendment is required because the waste
treatment facilities serving the City of Dublin is operating at or near maximum capacity. The discharge of
treated waste water into San Francisco Bay is detrimental to its sensitive ecosystem.
Cooling coil and comfort cooling equipment condensate waste discharge does not contain pollutants
which require treatment before being discharged into storm sewers or the ground.
.' Section 58, amends the code to comply with local sanitation district requirements regarding disposal for
.' ':.condensate for HV AC systems. The waste water treatment facilities serving the City of Dublin is
, operating at or near maximum capacity. The discharge of treated waste water into San Francisco Bay is
detrimental to its sensitive ecosystem.
