ADU Construction Questions, Answered
- How much does an ADU cost in Santa Monica?
In 2026, a garage conversion ADU in Santa Monica typically costs roughly $150,000 to $280,000, and a new detached ADU runs from about $150,000 for a compact unit near 400 square feet to $600,000 or more for an 800 to 1,000 square foot unit with significant site work. Coastal Zone review, utility upgrades and finish level are the biggest swing factors, so these are planning ranges, not quotes. - Can I convert my garage into an ADU in Los Angeles?
Yes. California law allows an existing garage on most single-family and multifamily lots in Los Angeles to be converted into an accessory dwelling unit, the city must approve a complete, code-compliant application within 60 days, and you generally do not have to replace the parking you lose. Because the conversion uses the garage's existing footprint, it is usually the lowest-cost way to add a legal rental or family unit. - How long does an ADU take to build in Los Angeles?
From the first design meeting to final inspection, an ADU in Los Angeles typically takes about 8 to 14 months. Design and engineering usually take 1 to 3 months, permit review up to 60 days for a complete application under state law (longer if corrections are needed), and construction roughly 4 to 6 months for a garage conversion or compact detached unit and 6 to 8 months for a larger or hillside unit. - How much does a 400-square-foot ADU cost?
A 400-square-foot ADU in Los Angeles or the San Francisco Bay Area typically costs roughly $150,000 to $300,000 in 2026, which works out to about $375 to $750 per square foot depending on whether it is a garage conversion or a new detached build, how far the utilities have to run, and the finish level. Small units cost more per square foot than large ones because the kitchen, bathroom and utility connections are fixed costs no matter the size.
