The only independent statewide survey of ADU owners, from UC Berkeley's Terner Center in 2021, found a median build cost of $150,000, about $250 per square foot, with 37 percent of ADUs under $100,000 and 71 percent under $200,000. Prices have risen since, and 2026 bids in Los Angeles depend on the kind of ADU, its size and the site. City fees are a small share: no impact fees up to 750 sq ft and no school fees up to 500 sq ft.

If the city misses the 60 days, the application is deemed approved. A pre-approved standard plan shortens plan check because LADBS reviews only the site-specific items. Those clocks do not include your design time, agency clearances or construction.

State law lets you turn the existing space into a home, plus up to 150 sq ft for an entry, with no setback for the existing building, no replacement parking and no new utility connection fee. LADBS's conversion bulletin (P/BC 2026-150, revised August 13, 2026) says what the garage must meet: sound footings, a sealed or new slab, a 7 ft ceiling, a 3 ft wide entry door, an escape window in each bedroom, heating, a kitchen, a bathroom and its own electrical panel.
