El Cajon allows conversion of existing garages, carports, and covered parking structures to ADUs under California Government Code Section 65852.2. Replacement parking spaces are not required when converting to an ADU. If parking is required for the ADU itself, it may be located in setbacks and in existing driveways as tandem parking. Building permits are required for the conversion. JADUs up to 500 sq ft may be created from existing attached space. The sewer lateral video requirement applies to ADU conversions. El Cajon's ADU height rules (12-20 feet depending on setback) apply to any vertical additions during conversion. The converted unit must meet all habitability and building code standards.
Unpermitted conversions are building code violations. Living in a converted garage without permits creates safety concerns and code violations.
