How a garage conversion works in San Diego County
A garage conversion turns space you already have into permitted living space, without building an addition. Most San Diego County homeowners take one of three routes. A garage-to-bedroom or living space conversion adds square footage to the main house. A junior ADU stays under 500 square feet and shares plumbing and entry with the home. A full ADU garage conversion becomes an independent unit with its own kitchen, bath, and entrance.
Garage Convert SD is a referral service, not a contractor. You tell us your city and your plan, and we match you with insured local crews who already work that area. Every garage conversion contractor in the network carries a license and insurance, and you get one written quote after an on-site visit. You can verify any license yourself at cslb.ca.gov.
What a garage conversion costs in San Diego County
A garage-to-bedroom or living space conversion typically runs $40,000-$70,000. A junior ADU typically runs $50,000-$90,000. A full ADU with kitchen, bath, and permits typically runs $80,000-$150,000. Permit fees, plumbing distance, and finish level move those numbers more than anything else, and the crew confirms a written price after seeing the garage.
Timelines run longer than most people expect. A permitted garage-to-ADU conversion typically takes 9-18 months from the first contractor meeting to the certificate of occupancy. Plan check alone runs 4-8 weeks in the City of San Diego and 6-12 weeks in unincorporated county areas and cities like Escondido and El Cajon.
