Our ADU Builder Service Areas in Los Angeles
At KN Remodeling, we design and build custom ADUs, backyard cottages, garage conversions and junior ADUs (JADUs) for homeowners across Los Angeles and nearby cities.

Why Every Neighborhood Needs a Local Plan
Every lot and every city has its own rules. That is why we plan each ADU around your neighborhood instead of using one design for every property. Across our ADU builder service areas, these are the details that change the most:
- Who issues the permit: most neighborhoods go through LADBS, but cities like Santa Monica, Beverly Hills, Culver City, West Hollywood and Malibu run their own building departments.
- Hillside and fire zones: areas such as the Hollywood Hills, Pacific Palisades and parts of Woodland Hills often need fire-resistant materials and extra review.
- Coastal rules: some lots near the ocean, in places like Santa Monica, Malibu and the South Bay beach cities, may need coastal review.
- Community review: Palos Verdes Estates and Rolling Hills have design review steps that add time to approvals.
- Lot layout: setbacks, alley access, utilities and existing structures decide where an ADU fits best.
Knowing these rules up front keeps your design realistic and your permit moving, no matter which of our ADU builder service areas you live in.

ADU Builder Service Areas FAQs
Which cities are included in your ADU builder service areas?
We build across the San Fernando Valley, the City of Los Angeles, the Westside, the South Bay and the Conejo Valley, including Simi Valley and Thousand Oaks. The full list of neighborhoods is shown on this page.
Do ADU rules change from city to city?
Yes. State law sets the basics, but each city has its own building department, plan check process and local details such as fire zone, coastal and design review rules.
My neighborhood is not on the list. Can you still help?
Often, yes. We regularly work in nearby communities. Contact us with your address and we will tell you quickly whether we can take on your project.
Does location change the cost of an ADU?
Location can affect permit fees, fire or coastal requirements and site access, but the size, type and finish level of your ADU usually matter more.
How do I know if my lot is in a fire or coastal zone?
We check this for you during the consultation. City of Los Angeles homeowners can also look up their parcel on ZIMAS, the city's zoning map.
