ADU builder
Los Angeles.

Los Angeles lots range from flat postwar yards to steep hillside sites above the basin. Foundations, garage slab reinforcement, and utility trenching have to account for mixed hillside, basin clay, and older utility corridors. Plan check runs through LADBS with Title 24 energy compliance and structural review on every permitted unit. Garage conversions often move faster than detached new-builds because the shell exists; hillside lots, tight side yards, and long utility runs can still add foundation and MEP cost. Most ADU construction in Los Angeles lands in the $100,000-$300,000 range — garage conversions from $90k–$160k, detached units from $190k–$290k. Permit fees, utility connections, soils reports, and design are quoted separately by line item. Finish level, fire sprinklers, and separate utility meters are the usual cost drivers after site conditions. Brentwood, Bel Air, Pacific Palisades, Encino, and the Valley all behave differently for access and inspections. We coordinate HOA/ARC packets — exterior materials, parking replacement, access plans — in parallel with city submittals when they apply. We already build in your backyard. Here's what we handle for Los Angeles homeowners.

We build pools and ADUs on the same lots across Southern California. When both are planned together, shared excavation, grading, and utility trenching often saves 10–15% versus separate projects.
