Building a Multigenerational ADU in Agoura Hills
Agoura Hills lots trend larger, hilly, and heavily landscaped — meaning ADU projects here are more custom, but the finished product is closer to a true guest house than a granny flat.
Best for
Ideal for families wanting a true separate-cottage feel within walking distance of the main house.

- Very Hig Fire Hazard Severity Zone throughout — Chapter 7A ignition-resistant construction is required and adds 8–12% to build cost.
- Larger lots allow legitimate 1,200 sq ft two-bedroom ADUs with parking.
- Design review board common; expect one round of revisions.
Zoning note: Fire hardening (ember-resistant vents, Class-A roofing, non-combustible cladding) is not optional — build it into the first design pass.
