Full Breakdown
060 governs accessory structures other than ADUs and JADUs, which are regulated separately. 020 table. If an accessory building is attached to the main house, or sits less than five feet from it, the code treats it as structurally part of the main building and requires it to meet all the same development standards, including setbacks and height, that apply to the house itself. For setbacks, the minimum side and rear yard setback is five feet for carports and three feet for all other accessory structures such as sheds and detached garages.
On the permit side, a building permit is not required for a detached accessory structure that is 128 square feet or less, no more than 12 feet in height, not habitable, and does not require utilities; any shed larger than that, taller than 12 feet, built for living space, or wired for power or plumbed for water needs a building permit. The section also bars kitchens from being installed in any accessory structure regardless of size.
Violations & Fines
