What Is an ADU Garage Conversion?
An ADU (Accessory Dwelling Unit) garage conversion transforms your existing garage into a separate, self-contained living space — complete with bedroom, bathroom, kitchen, and its own entrance. Under California's ADU laws (AB 2221, SB 897), most homeowners can convert their garage into a legal ADU with streamlined city approval.
ADU garage conversions are one of the fastest-growing home improvement projects in Los Angeles. They add living space, generate rental income (\$1,800–\$3,500/month in most LA neighborhoods), and significantly increase property value.

Frequently Asked Questions
In Los Angeles, a full ADU garage conversion typically costs \$60,000–\$130,000 for a turnkey, permitted build. This includes design, permits, construction, plumbing, electrical, and all finishes. Simpler conversions without full kitchens or bathrooms can run \$35,000–\$60,000.
Plan on 4–8 weeks for permit approval and 8–16 weeks for construction. Total timeline from first consultation to Certificate of Occupancy is typically 5–7 months for a full ADU build in Los Angeles.
Under California law (AB 2097), if your property is within half a mile of public transit, you cannot be required to replace the parking lost by converting your garage. In most urban LA neighborhoods, this exemption applies — your contractor can confirm for your specific address.
