ADU Construction in Beverly Hills
Serving 90210 · 90211 · 90212 and West Hollywood, Bel Air, Westwood
Beverly Hills ADU work is not an LA ADU with a different address on the plans. It's a separate-city process that starts with the City of Beverly Hills BSED, follows the city's own review path, and finishes on a calendar that typically runs longer than an LADBS ADU.
Building an ADU inside the Beverly Hills city limits
First: what the lot can actually support
Before Design Onn Point draws anything, we map setbacks, height limits, and buildable envelope against the city's ADU rules. That's the honest starting line — not a floor plan.
The BSED permit path
Every plan sheet, every correction, every sign-off happens inside the City of Beverly Hills, not LADBS. The plan check typically takes longer, and we build that reality into the schedule so you're not chasing the process yourself.
Style that respects the main house
A Beverly Hills ADU behind a Regency main house should read like a Regency companion. Behind a Spanish revival, it should read like a small casita. Behind a traditional house, it should read like a matched pool house. We design the ADU to belong to the property.
The +20-30% band, line by line
The uplift over a standard LA ADU is the longer permit calendar, the city's higher expected finish level, and the material choices these properties ask for. Design Onn Point (CSLB #1133368), with 20+ years of Onn’s building behind it, prices it that way from the first meeting.
When feasibility comes back thin
If the setbacks, the height limit, or the lot geometry mean the ADU doesn't pencil, we say so early. A no in week one is better than a stalled plan set in month four.
A second unit inside a city that runs its own rules
State law sets the floor for what a city must allow, and Beverly Hills applies it through its own building department with its own local standards layered on top. The practical consequence is that an ADU here is not the same administrative project it is a mile east in LA proper, even when the unit is identical. Design review reaches further, the queue is separate, and the local requirements around siting, height and what is visible from the street are stricter than the state minimum. It is entirely doable and it rewards drawings that anticipate the local standard instead of the state one. Assume LADBS habits here and the schedule breaks before the construction does.

What's different about adu construction in Beverly Hills
Beverly Hills enforces its own ADU rules, not just state law
Beverly Hills B&S applies its own ADU code section alongside state law. State law sets the floor; the city can layer additional requirements around setbacks, parking, and design review on landmark or historic parcels. Detached ADUs on R-1 parcels are generally permitted under state preemption, but the specific siting envelope on a Beverly Hills parcel is often tighter than state law alone would suggest. We verify the local code path against the specific parcel before committing the design to a particular footprint.
BH lot dimensions limit detached-ADU placement options
Many Beverly Hills R-1 parcels north of Wilshire have rear-yard depth and side-yard width that constrains where a maximum-size detached ADU can physically sit while meeting setback minimums. On some parcels, the only feasible footprint is a junior ADU or a converted garage rather than a new detached structure. We site-walk every Beverly Hills ADU project against the survey before committing to a design — the parcel's actual dimensions dictate what fits.
Most BH ADUs go to family use rather than market-rate rental
The dominant Beverly Hills ADU motivation is adult-child housing, in-law residency, or staff quarters rather than open-market rental income. That sets the program (full kitchen, primary bed and bath, separate entrance, finishes matching the main house) and the budget tier. We design the ADU as a finished extension of the main residence rather than as a rental-grade build-out, because that's what the client base consistently asks for.
