VI.FAQ

Garage Conversion — Frequently Asked Questions

Will I have to add replacement parking?

For garage-to-ADU conversions, generally no. State law (AB 671 and follow-ons) prohibits most cities from requiring replacement parking when a garage is converted to an ADU on most residential lots. For non-ADU conversions, replacement parking may apply — we verify city-specific rules before design.

How much does a garage conversion cost?

South Bay garage-to-ADU conversions typically run $80,000–$180,000 depending on size, finishes, utility upgrades, and slab condition. Conversions to non-ADU living space (bedroom, office) without full kitchen and bath run lower. We quote fixed-price after design and engineering.

How long does a garage conversion take?

From design start to final inspection, a typical garage-to-ADU conversion runs 6–10 months: 1–2 months design, 2–3 months permitting, and 3–5 months construction. Faster than a detached ADU because the foundation and roof already exist.

Can I convert my garage and still have a place for my car?

Often yes — many South Bay homes have driveway space or detached carports. For two-car garages, we sometimes split the space: one bay remains storage/parking, the other becomes living space or a JADU. We design around your priorities.
