Your Trusted Local ADU Partner
Whether you picture a private guest house tucked into a hillside lot or a garage conversion with a view, KN Remodeling is here to bring your ADU vision to life in Hollywood Hills.
Nearly all of Hollywood Hills falls under the City of Los Angeles' Baseline Hillside Ordinance, which limits grading based on slope and sets height, setback, and floor-area rules specific to hillside lots, and most of the area is also a Very High Fire Hazard Severity Zone requiring Chapter 7A fire-hardened construction. Hillside plan checks typically take longer than flat-lot projects given the added geotechnical and access review. We build in that extra time upfront and manage the full engineering and permitting process so there are no surprises partway through.

Frequently Asked Questions
Hillside construction carries real cost premiums, so pricing in the Hollywood Hills runs higher than flatland neighborhoods. As a general guide:
- Garage conversion or Junior ADU (JADU): roughly $100,000 to $160,000
- Detached custom ADU (500 to 800 sq ft): roughly $200,000 to $300,000
- Larger detached luxury ADU (800 to 1,200+ sq ft): $320,000 to $400,000+
Steep lots around the Bird Streets and Whitley Heights often need caisson foundations, retaining walls, or extended grading, which affects the final number. We provide a written, itemized estimate after your free in-home consultation.
Hillside construction in the Hollywood Hills generally takes longer than flatland projects, both in design and on-site work.
- Active construction typically runs four to seven months, depending on foundation type and site access
- LADBS requires a soils and geology report under the Baseline Hillside Ordinance for hillside lots, and Fire Department review for Very High Fire Hazard Severity Zone compliance runs concurrently, together adding three to five months before permits issue
- Narrow, winding streets in areas like the Bird Streets can limit equipment access, which affects both scheduling and staging
You'll receive a written schedule that accounts for these hillside-specific steps, plus regular updates as the project moves forward.

Yes, permits are required for all new ADU construction, and Hollywood Hills has more permitting layers than flatland LA neighborhoods.
- Properties fall under LAMC's Baseline Hillside Ordinance (12.21 A.17), which requires a slope analysis and, in most cases, a soils and geology report before LADBS issues a grading or building permit
- The neighborhood is largely within a Very High Fire Hazard Severity Zone, which adds fire-hardened material and brush clearance requirements
- Canyon and slope setbacks apply on many parcels, and lots near an Alquist-Priolo earthquake fault zone carry additional geologic setback rules
We handle all architectural filings, geotechnical coordination, and City reviews so you're not navigating LADBS's hillside process alone.
Building in the Hollywood Hills means planning around the terrain from day one:
- Steep Terrain: canyon and slope setbacks, plus engineered retaining walls, are common on hillside parcels like those in the Bird Streets and Whitley Heights
- Fire Zone Compliance: most of the neighborhood sits in a Very High Fire Hazard Severity Zone, requiring fire-resistant materials and defensible-space landscaping
- Site Access: narrow, winding streets can limit crane placement and material delivery, which shapes construction sequencing
- Soils and Geology: a licensed geotechnical report is typically required before design is finalized, and its findings often drive foundation choice
We evaluate all of these site-specific conditions during your free initial consultation.
