FAQ

Common Questions About Garage Conversions

How long does a garage conversion take?

Garage conversion ADUs typically take 12–20 weeks of construction, plus 2–4 months for design and permits. Total project timeline is usually 5–8 months from contract to certificate of occupancy.

How much does a garage conversion cost in the Bay Area?

Garage conversion ADUs commonly run $150,000–$280,000 depending on size, foundation condition, and finish level. Conversions to home office or gym (without full kitchen/bath) typically run $80,000–$150,000.

Can I convert my garage to an ADU?

Yes — California state ADU law explicitly permits garage conversions and has eliminated many of the obstacles cities used to impose (like requiring replacement parking). We handle the permit submittal and inspection coordination.

Do I need to add parking when I convert my garage?

No — California state law prohibits cities from requiring replacement parking for garage-to-ADU conversions. This is one of the major benefits of state ADU law.

Will the conversion need foundation upgrades?

Often yes. Existing garage slabs were not designed for living loads or insulation requirements. We typically add perimeter footings and reinforce the slab as part of the conversion.
