ADUs & Additions in Hollywood Hills

Los Angeles Department of Building and Safety (LADBS). Private pools in the City of Los Angeles are permitted through a combined Building-Mechanical permit. Plumbing plan check applies to apartment and commercial pools, not single-family homes, and using an LADBS pre-approved standard plan shortens plan check. Nearly all of the Hollywood Hills sits in the Hillside Grading Area under the Baseline Hillside Ordinance, and much of it is in a Very High Fire Hazard Severity Zone. Grading, retaining and haul routes are permitted separately from the pool itself. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.

Steep, view-first parcels where structure and access drive both the schedule and the budget. This is the most engineering-heavy work we do, and it is on our doorstep. In practice that means steep parcels usually require caissons and engineered retaining before a pool shell can be formed.

All of it, including Hollywood Heights, Nichols Canyon, Laurel Canyon, Outpost Estates. We are based in Los Angeles at Cahuenga Pass, so Hollywood Hills is a short run for our crews rather than a job we service from out of the area.

Detached ADU in this market generally runs $150,000 to $400,000+. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.

Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.

Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.

California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.

Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
