Building an ADU in Woodland Hills
Woodland Hills covers two different kinds of ground. North of Ventura Boulevard the blocks are mostly flat, and a backyard ADU or garage conversion is usually simple to lay out. To the south the streets climb into the Santa Monica Mountains toward Mulholland Drive, where slope, fire rules and scenic-parkway review all affect the design. A lot of owners here are building: the Canoga Park, Winnetka, Woodland Hills and West Hills planning area saw about 976 ADU permits in 2025, the most of any planning area in Los Angeles, per state housing reports.
ADU Resource Center designs, permits and builds ADUs across the west San Fernando Valley with one in-house team. Our nearest finished projects are in Van Nuys, where we built a vaulted-ceiling unit beside the owners' garage, and in Lake View Terrace, where a 1,200 sq ft, three-bedroom ADU houses three generations of one family. If you live just west of here, see our West Hills page.
Before construction starts you get a fixed quote. One project manager runs the job from design through final inspection, and we help you line up financing.

Local know-how
What to know before building in Woodland Hills.
LADBS handles the permit
Woodland Hills is a City of LA neighborhood, so plans go through LADBS. For a simple flat lot, LA's Standard Plan program has pre-approved designs that can shorten review.
Mulholland Scenic Parkway
Some hillside lots near Mulholland Drive sit inside the Mulholland Scenic Parkway Specific Plan, which adds a design review step with City Planning. We check whether your parcel is covered before we draw anything.
Fire zones in the hills
LAFD's very high fire hazard severity zone takes in parts of Woodland Hills, mostly the hillside streets. An ADU there needs ignition-resistant construction, and slope work like grading or retaining walls adds to the quote.
The busiest ADU area in LA
About 976 ADU permits were issued in this planning area in 2025, up from about 696 in 2023, per state housing reports. To see where your own project might land, the ADU cost calculator gives a quick starting estimate by size and finish.

Questions
Woodland Hills ADU questions, answered.
Still have a question? Ask us during your free consultation.
What does an ADU contractor in Woodland Hills handle for me?
With us, one team does the whole job: site visit, design, the LADBS permit package, plan-check corrections and construction. That spares you from coordinating a separate architect and builder, and one project manager stays with you from the first drawing to final inspection.
Who approves ADU plans in Woodland Hills?
Woodland Hills is part of the City of Los Angeles, so plans go to LADBS (the Department of Building and Safety). The city has to act on a complete ADU application within 60 days. If your lot is inside the Mulholland Scenic Parkway Specific Plan, City Planning also reviews the design.
How much does an ADU cost to build in Woodland Hills?
Our construction rate is flat: $275, $300 or $325 per sq ft for basic, mid-range or luxury finishes. A 600 sq ft one-bedroom comes to roughly $165K–$195K in construction. A hillside lot can add grading, retaining walls or an engineered foundation, and those show up in your fixed quote before you sign.
My house is up in the hills south of Ventura Boulevard. Can I still add an ADU?
Often you can, but plan for more steps. Hillside lots here can fall in a very high fire hazard severity zone, which calls for ignition-resistant roofing, vents and siding, and a steep pad may need a soils report and engineered foundation. We look at the slope, access for equipment and the zoning overlays before we quote.
How big can my Woodland Hills ADU be?
State law allows detached ADUs up to 1,200 sq ft on many lots, and a junior ADU of up to 500 sq ft inside the house. What fits on your lot depends on its size, slope and setbacks. ADU rules change, so we confirm the current limits for your parcel on the consultation.
