Why Hillstar
Why Beverly Hills Properties Choose Hillstar
This city runs its own building department and holds its own design standards. An ADU here has to be planned for both from the first sketch.
The City's Own Desk
Beverly Hills Community Development issues every permit — no LADBS, no LA Standard Plan. Our drawings are made for the Beverly Hills code path.
Flats-Lot Geometry
Wide, deep R-1 parcels below Sunset accept detached units gracefully — and many estates carry generous garages that convert cleanly.
Hillside & Trousdale Fluency
Above Sunset, hillside review adds grading and height analysis; Trousdale's single-story character shapes roof form. We design to both.
Estate-Grade Execution
Finish level to match the property — guest quarters, staff quarters, studios, and pool-adjacent units detailed properly.
Utilities Sized Early
Older estates often need service upgrades before a second dwelling's load lands. The load math happens during design.
Discreet, Managed Builds
Tight scheduling, clean sites, and respectful crews — the way work should look on these streets.
Our process
The Beverly Hills ADU Path
Four stages, each aligned to the city's review.
1
Property Assessment
Lot geometry, hillside status, existing structures, and utility capacity reviewed on-site.
2
Design & City Submittal
Drawings tailored to Beverly Hills' requirements and filed with Community Development; corrections handled by us.
3
Construction
Foundation to finish with our own crew and every city inspection met on schedule.
4
Completion
Final sign-off, walkthrough, and a written workmanship warranty.
Local conditions
Permits, Lots & What's Specific to Beverly Hills
Beverly Hills is its own city with its own building department. State ADU law (Government Code §65852.2) still applies — but the permit path, the design review layer, and the inspection cadence are all different from anything in the City of Los Angeles. Plan accordingly.
Permit jurisdiction
City of Beverly Hills Community Development — Building & Safety — issues every Beverly Hills ADU permit. LADBS does not. The LA City Standard ADU Plan Program is not accepted; designs must be drawn for the Beverly Hills code path. Expect tighter coordination with the city's plumbing, electrical, and final-inspection schedule than the LADBS volume cadence.
Lot & zoning patterns
The Flats below Sunset run to wide, deep R-1 lots that take detached ADUs cleanly. Trousdale Estates, Beverly Crest, and the BHPO (Beverly Hills Post Office) hillside band sit on steeper, view-driven parcels where setbacks, height envelopes, and pad geometry shape every feasibility call. Many estates have generous existing detached garages, which makes garage conversion an unusually clean play here.
Design overlays you'll see here
Hillside parcels above Sunset trigger Beverly Hills hillside review on top of the standard plan check — grading limits, height-envelope rules, and view-impact analysis. Trousdale carries a long-standing single-story design tradition; ADU height and roof form are evaluated against that pattern. Many north-of-Sunset hillside addresses fall inside California Fire Hazard Severity Zones; where they do, Chapter 7A WUI ignition-resistant assemblies and defensible-space compliance apply.

FAQ
Beverly Hills ADU — FAQ
City review, hillside parcels, garage conversions, and what estate ADUs really involve.
Is an ADU even allowed in Beverly Hills?
Yes — state ADU law applies in every California city, Beverly Hills included. What's local is the process: the city's own Building & Safety reviews the plans, and hillside parcels add the city's grading and height analysis. The LA Standard Plan Program isn't accepted here; designs are city-specific.
Our property is in Trousdale. What's different?
Trousdale's long-standing single-story character informs how height and roof form are evaluated. An ADU there is designed low and integrated, matching the neighborhood pattern. On BHPO and Beverly Crest hillside parcels, grading limits and view analysis join the review instead.
Is a garage conversion the fastest route?
Frequently. Many Beverly Hills estates carry large detached garages, and a conversion inside the existing footprint avoids most setback questions while preserving the grounds. Whether it beats a detached new-build depends on the garage's structure and what you want the unit to do.
Can the ADU be rented, or is it for guests and staff?
Either. California law removed owner-occupancy requirements for detached and attached ADUs, so rental is legal; many owners here build for family, guests, or staff instead. JADUs — units carved from the main residence — still carry an owner-occupancy condition.
What's the realistic budget conversation?
Estate-grade finishes and hillside engineering set the range, and honesty requires seeing the property first. Expect an itemized written quote after the visit — structure, utilities, finishes, and review costs each visible — with changes documented for approval before execution.
