Redondo Beach, CA Accessory Structures: Shed & Carport Rules (2026)

1500 governs accessory buildings across every residential zone except the R-MHP mobile home park zone. Subsection (a) requires a minimum five-foot separation between an accessory building and the dwelling unit or other accessory buildings on site, waived only if the structure is unenclosed. Subsection (b) limits every accessory building to one story. Subsection (c) then adds a stricter layer for any accessory structure occupying part of a required rear setback: height cannot exceed 15 feet overall, with perimeter walls capped at 10 feet measured from existing grade to the top plate and a parapet allowed no more than three feet above that plate.

Combined floor area of all accessory structures located in the rear setback cannot exceed 800 square feet. The total side setback, measured from each property line to the structure's wall, must equal at least 10 feet, with a minimum five-foot setback on each side if any portion sits forward of the rear 23 feet of the lot or if the structure is habitable. Corner lots carry a five-foot minimum exterior side setback, and reverse corner lots must match the front setback of the adjoining key lot.

Rear setback itself is not required for a nonhabitable accessory structure, except a habitable structure needs a five-foot rear setback and a garage facing an alley must sit at least 25 feet from the alley's far right-of-way line. Property abutting an alley can skip the side setback for a nonhabitable structure if no part of it extends past a line 45 feet from the alley's opposite property line.
