Full Breakdown
Municipal Code § 11.43.050(M) governs garage conversions to ADUs in South Gate. No additional setback is required for an existing garage converted to an accessory dwelling unit. The garage door itself must be removed and replaced with a new facade that includes at least one window or entryway, so the converted structure no longer reads as a garage from the street. The conversion is also covered by the chapter's expansion allowance, letting a converted garage grow by up to 150 square feet for ingress and egress.
Violations & Fines
Converting a garage into livable space without removing the garage door and installing a compliant facade, or without going through the ADU permit process under § 11.43.060, violates § 11.43.050(M) and can void the certificate of occupancy.
