Berkeley R-1 zones limit main building lot coverage to 40 percent and total structure coverage to 50 percent, with ADUs and SB 9 units subject to state-law overrides.
Berkeley Municipal Code Title 23 regulates lot coverage separately for main buildings and total structures. In R-1 and R-1A single-family zones, the main building footprint typically cannot exceed 40 percent of lot area, with total coverage including accessory structures capped at 50 percent. Floor Area Ratio (FAR) limits also apply, typically 0.4 to 0.6 in single-family zones depending on lot size. R-2 and R-3 multifamily zones allow higher coverage up to 50-60 percent. State ADU law requires cities to allow an 800 square foot ADU regardless of local FAR or coverage limits. SB 9 urban lot splits and duplex conversions must be permitted even if they exceed base coverage standards. Impervious surface limits under the Stormwater Management Ordinance may further restrict paved areas.
