Garage Conversion

Most garage conversions in the LA area run from about $60,000 to $150,000. A simple finished room without plumbing sits at the low end; a full ADU conversion with a kitchen, bathroom, and separate utilities costs more. Because the slab, walls, and roof already exist, it is usually the least expensive way to add legal square footage.

Yes. Converting a garage into habitable space always requires permits. Unpermitted conversions create serious problems at resale, can be flagged by appraisers and insurers, and may have to be reversed. We handle the permitting so the finished space is fully legal.

Under current California ADU law, replacement parking generally cannot be required when you convert an existing garage into an ADU. Local rules still vary in the details, so we confirm the specific requirements for your address during the feasibility check.

Habitable space requires a minimum ceiling height, and many older garages are close to the line. We measure during the feasibility visit. If the height is short, options include lowering the slab or modifying the roof structure — we’ll tell you what’s realistic.

It gets framed in and finished with a wall, windows, or a door, depending on the design. Done well, the finished exterior reads as part of the house rather than a filled-in garage.
