San Marcos 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 a garage to an ADU. If parking is required for the ADU itself, it may be located within setbacks and in existing driveways as tandem parking. Building permits are required for the conversion, including structural, electrical, and plumbing upgrades. JADUs (up to 500 sq ft) may be created by converting existing attached space within the primary residence. The converted unit must meet all habitability and building code standards. ADUs created from garage conversions are exempt from lot coverage calculations.
Unpermitted conversions are building code violations. Living in a converted garage without permits is a safety and code violation.
