ADUs & Additions in North Hollywood

Los Angeles Department of Building and Safety (LADBS). LADBS is the permitting authority, and Valley projects are plan-checked and inspected through the Van Nuys Development Services Center. No coastal or hillside overlay applies on this section of the valley floor.

Where a parcel falls in a CGS-mapped liquefaction zone (ZIMAS shows it), LADBS Information Bulletin P/BC 2026-044 still exempts one- and two-family dwellings, ADUs under three stories, and pools, spas and decks from the liquefaction-zone investigation, so soils report needs are settled with plan check.

The city's protected tree and shrub ordinance covers oak, western sycamore, black walnut, California bay, Mexican elderberry and toyon at four cumulative inches of trunk diameter, and removal or encroachment needs an Urban Forestry permit. Pool barrier height, self-closing and self-latching gates and drowning-prevention features are verified at final inspection, and review durations vary.

We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

Most parcels are compact rectangles with the house pushed toward the street and narrow side yards, leaving a modest but workable rear yard. Detached rear garages are common and are frequent conversion candidates. One local condition that shapes the work: Narrow side yards decide whether an excavator reaches the rear or the dig becomes a conveyor-and-hand-load operation.

All of it, including NoHo Arts District, North Hollywood West and Toluca Woods. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.

Detached ADU: generally $150,000 to $400,000+ across Southern California. 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.
