Building a Multigenerational ADU in Woodland Hills
Woodland Hills is one of the strongest ADU markets inside the City of Los Angeles: postwar ranch homes on deep flat lots south of Ventura Boulevard, and larger hillside parcels climbing toward Mulholland. Same LADBS process as the rest of the city, with far more usable rear yard than most of it.
Best for
The Valley's best balance of lot size, price, and access to medical care — a practical pick for adult children keeping a parent nearby without leaving the city.

- Flat lots between Ventura Blvd and Vanowen commonly run 7,500–12,000 sq ft — room for a full 1,000 sq ft detached unit with real separation from the main house.
- Hillside parcels north of Mulholland Drive and in Warner Center's western edge trigger Baseline Hillside Ordinance review, grading limits, and often caissons.
- Mature oaks are frequently protected — a protected tree within the build footprint requires a permit and an arborist report, and can force the ADU to move.
Zoning note: Reviewed by LADBS under the citywide ADU ordinance. Portions west of Topanga Canyon Blvd fall in a Very High Fire Hazard Severity Zone, adding Chapter 7A requirements and LAFD clearance.
