A garage conversion is the most cost-effective square footage you can add to a Bay Area home — the foundation, walls, and roof already exist, so you're finishing space rather than building it from scratch. It's the fastest path to an extra bedroom, a real office, or an income-producing ADU.
ODL Construction converts garages properly: code insulation, permitted electrical and plumbing, real foundations and egress, and finishes that make the space feel like part of the house — not a converted garage. We handle whether you want a habitable room or a fully independent ADU.
From a Union City conversion that adds a bedroom for a multigenerational family to a Sunnyvale garage-to-ADU built for rental income, we bring it up to code and finish it right.

We pass inspection and hand over finished, code-compliant living space.
How much does garage conversion cost in the Bay Area?
There's no honest one-size-fits-all price in construction — the true cost of your project depends on scope, size, materials, engineering, permits, and site conditions. That's why we never quote from a table: every estimate is customized to your project and budget after a free consultation and site visit.

Financing options →Timeline
A habitable-room conversion often takes 4–8 weeks; a garage-to-ADU typically runs 3–4 months including permitting.
Permits & code
Garage conversions require permits for the change of use, insulation/energy (Title 24), electrical, egress, and — for ADUs — the state's ministerial ADU review. We handle all of it.
Key things to consider
- Room vs. ADU: a kitchen and bath turn a conversion into an income unit but add cost.
- Parking rules have relaxed for ADUs, but confirm room-conversion parking impacts.
- Proper insulation, egress, and moisture control separate a real conversion from a code violation.
- Replacing the garage door with a finished wall is what makes it stop looking like a garage.
