ADUs & Additions in Van Nuys

Los Angeles Department of Building and Safety (LADBS). Permits are issued by LADBS, and the Van Nuys Development Services Center at 6262 Van Nuys Boulevard handles plan check, permitting and inspection for this part of the San Fernando Valley. There is no coastal zone or hillside overlay to contend with here, but the city's protected tree and shrub ordinance still applies to oaks, western sycamores and Southern California black walnuts at four cumulative inches of trunk diameter or more. Portions of the valley floor sit inside state-mapped liquefaction zones, and where a parcel does, a geotechnical report is required before a pool or ADU foundation is approved. Properties close to the airport can also trigger FAA airspace notice for tall structures or crane operations, and processing durations vary with scope. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.

Typical parcels are flat rectangular tracts of roughly 6,000 to 8,000 square feet with a single-story house set toward the street and a deep, level rear yard. Larger custom properties appear in the older ridge and estate pockets. In practice that means the valley floor here is deep, fine-grained alluvium that excavates predictably but can be expansive enough to require deepened footings or a post-tensioned slab under a new detached structure..

All of it, including Kester Ridge, Sherman Circle, Lake Balboa, Valley Glen. We are based in Los Angeles at Cahuenga Pass, so Van Nuys 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.
