Why homeowners pick us

Why do San Diego homeowners choose Garage Convert SD?

Garage conversion projects in San Diego get oversold on scope, underestimated on permits, and handed off between too many subs. We match you with insured local crews, walk you through California ADU rules, and get you one written estimate.

  • One site visit, one written quote. A crew assesses your garage in person, confirms ADU or JADU eligibility under California law, reviews setbacks and city requirements, and hands you a written scope. No phone bids off a description and no surprise permit costs after the job starts.
  • Flat-rate pricing, no hourly games. You hear the price before we start. Book-rate repairs, not billable hours.
  • Honest scope, not an oversized project. Sometimes a junior ADU covers what a homeowner needs without the cost of full plumbing and a separate meter. We tell you when to simplify, when to invest, and which conversion type actually matches your property and budget.
  • We answer after 5 p.m. Real 24/7 emergency response. Ring once, get a human.

Do I need a permit to convert my garage in San Diego?

Yes. Garage conversions that change the use of the space require a building permit in San Diego County.

Your crew handles all permitting when the scope calls for it.
