Garage Conversions in Santa Monica

Santa Monica homeowners call AAA All Star Construction when they want the job done right. A garage conversion is often the fastest and most affordable way to add a legal living unit in Santa Monica. The walls, slab and roof are already there; we bring the space up to code for habitation and finish it like the rest of your home.

Santa Monica is about 12 miles southwest of our North Hollywood office, so our Southern California crews are on site quickly for estimates, inspections and the day-to-day work.

What's included

Assessment of the existing slab, framing and roof
Insulation, drywall and Title 24 energy upgrades
Replacing the garage door with a code-compliant wall and windows
New plumbing for a kitchen and bathroom
Electrical subpanel, lighting and outlets
Flooring, paint and finish carpentry

Building in Santa Monica

Salt air and the marine layer in Santa Monica are hard on exterior materials. We specify corrosion-resistant fasteners and flashing, moisture-tolerant finishes and good ventilation so the work lasts near the coast.

Building permits for Santa Monica projects are issued by the City of Santa Monica. Converting an existing garage into an ADU is covered by the state ADU laws, and replacement parking is generally not required when a garage is converted. We confirm the details with the Santa Monica building department.

What affects the price

Condition of the existing slab and whether it needs a vapor barrier or leveling
Adding a kitchen or bathroom (sewer and water connection)
Electrical service capacity
Windows, egress and ceiling height
Finish materials

Santa Monica Garage Conversions FAQ

Is a garage conversion cheaper than a new ADU?

Usually, because the foundation, walls and roof already exist. The final price depends on the condition of the structure and whether you add a kitchen and bathroom.

Do I have to replace the parking I lose?

Under California ADU law, replacement parking is generally not required when a garage is converted to an ADU. We verify this for your specific Santa Monica property.

How long does a garage conversion take?

Construction typically runs 8 to 14 weeks after permits are issued, depending on scope.

Do you serve all of Santa Monica?

Yes. We work throughout Santa Monica and the surrounding Los Angeles County communities from our North Hollywood office. Call 844-975-5512 to schedule a free estimate.
