comply with all the requirements of this Title to the principal structure.
2. Breezeways. A breezeway or other extension of the principal structure or
accessory structure roof may connect the accessory structure to the principal
structure, but it shall not be considered part of the principal structure. The

Chapter, shall have a maximum height of 15 feet. Detached accessory structures in
