The Right Image Approach

Beverly Hills Lots
and the Second Unit They Can Hold

Beverly Hills reviews ADUs under its own ordinance and through its own Building & Safety Division, ministerially as state law requires, but with the city's single-family rules for the Central Area, the Hillside Area and Trousdale Estates layered on top. The Flats are the easiest sites: 8,000–20,000 sq ft lots with a detached garage on an alley, where a conversion or a new detached unit keeps its own entrance without crossing the main house; the hillside parcels above Sunset need the slope and the access designed first, and Trousdale's 14-foot height limit rules out a second-story unit.

The typical site is an 8,000–20,000 sq ft Central Area lot with a detached garage and alley access, or a hillside parcel where slope and the Hillside Area rules set the design. What decides between a garage conversion, a JADU and a detached unit is that lot, the sewer route and the main panel: older 100- to 125-amp panels in large houses; a 48-inch range, column refrigeration and EV charging usually mean a 200-amp Southern California Edison service upgrade. Every unit gets a full kitchen and bath, its own sub-panel and, for a detached unit, its own address.

One contract covers the whole job: a licensed architect draws the plans, a structural engineer stamps them, we file with the City of Beverly Hills and answer the corrections, and our own crew builds through final inspection and the Certificate of Occupancy. Our office is in Valley Glen, about 25–35 minutes away, and the project lead who does the feasibility visit runs the build.

What We Build

Three Paths
to a Second Unit

01

Detached ADUs

A ground-up standalone home in the backyard — up to 1,200 sq ft, one or two bedrooms, its own entrance and address. On typical Beverly Hills R1 lots we most often build in the 600–1,000 sq ft range, sized to the yard and your budget.

02

Garage Conversions

The most cost-effective Beverly Hills path. We convert your existing detached or attached garage into a legal ADU — foundation and slab upgrades, framing, insulation, windows, a full kitchen and bath, and code electrical and plumbing, all permitted.

03

Junior ADUs (JADUs)

A JADU (up to 500 sq ft) carved out of the existing house — often a converted bedroom or garage-adjacent space with an efficiency kitchen. The lowest-cost way to add a legal, rentable unit without building new square footage.

04

City ADU Review

Beverly Hills reviews ADUs ministerially under its own ordinance: a complete, code-compliant application is approved without a public hearing. We prepare the submittal to the city's own plan-check list, answer the corrections and schedule every inspection through the Certificate of Occupancy.

05

Utilities & Site Work

Water, sewer, and electrical connections; addressing; grading and drainage; and the exterior work that ties the ADU into the property. The unglamorous coordination that quietly makes or breaks an ADU timeline — handled in-house.

06

Design, Permits & Build

One contract from concept to keys: a licensed architect draws the plans, a structural engineer stamps them, we file with the City of Beverly Hills, and our own crew builds through final inspection and the Certificate of Occupancy.

Building in Beverly Hills

Why Beverly Hills
Works for ADUs

Beverly Hills is its own city with its own Building & Safety Division at City Hall, its own water utility and Southern California Edison for power, and a single-family zoning code divided into three regulated areas: the Central Area, which is the Flats north of Santa Monica Boulevard, the Hillside Area north of Sunset, and Trousdale Estates with its 14-foot single-story height limit. The blocks south of Wilshire carry the city's 1930s–50s single-family and duplex streets. Our office is in Valley Glen, about 10 miles north over Coldwater Canyon or Beverly Glen, a 25–35 minute drive. One caution: Beverly Hills Post Office addresses north of the city line are City of Los Angeles and go through LADBS, and we confirm the jurisdiction on the parcel before anyone draws a plan.

No replacement parking is required when a garage converts, units under 750 sq ft are exempt from impact fees, and the city must act on a complete application within 60 days; what changes is the submittal, which follows Beverly Hills' own plan-check list, and the utilities, which are the city's water service and Southern California Edison rather than LADWP. We check the zoning on the city's parcel map, the panel, the sewer route and the area rules at the feasibility visit, and file at City Hall.

An ADU in Beverly Hills is permitted through the City of Beverly Hills Community Development Department, Building & Safety Division, under ministerial review, which approves a code-compliant unit without a public hearing, and the utility connections go through the City of Beverly Hills water utility and Southern California Edison. Units under 750 sq ft pay no impact fees, a garage conversion needs no replacement parking, and the unit can be rented on leases of 30 days or more once the Certificate of Occupancy is issued.

What Clients Say About
Our ADU Construction Work

★★★★★

ADU build in Sherman Oaks. Permits pulled, inspections passed, project completed in 14 weeks. They were transparent about every step. We're renting the unit already — it's beautiful and fully up to code.

We had a complex ADU project that other contractors kept turning down or quoting absurd prices. Right Image Builders handled permits, design, and construction seamlessly. This is the most professional contractor I've ever worked with in 15 years of owning property in LA.

We had tried two other contractors who couldn't navigate the LADBS permit process for our ADU. Right Image Builders had the permit in hand within six weeks of starting design and delivered a beautiful unit on the exact date promised. It's now generating $2,800 a month in rental income. Best investment we've made in this property.

Beverly Hills ADU FAQ

Questions We
Hear in Beverly Hills

Almost certainly. Beverly Hills is largely 1950s R1 single-family lots, and California ADU law lets nearly every single-family property add at least one ADU plus a Junior ADU. Beverly Hills is one of the highest-volume ADU and garage-conversion areas in Los Angeles precisely because these tract lots have the room and the alley or driveway access to make it work. We confirm exactly what your specific lot allows at the free site visit.
Under current California rules, a detached ADU can generally be built up to 1,200 sq ft, and a Junior ADU (JADU) is capped at 500 sq ft and must be within the existing home. On typical Beverly Hills R1 lots, most detached units we build land in the 600–1,000 sq ft range — a comfortable one or two-bedroom. We size the ADU to your lot, your budget, and whether you're housing family or renting.
Yes — Beverly Hills is its own city, so your ADU is permitted through Beverly Hills Building and Safety, with submissions filed at the City of Beverly Hills Community Development Department, Building & Safety Division, at City Hall, 455 N. Rexford Drive. We manage the whole process, and where it fits we use the Beverly Hills Building and Safety pre-approved ADU ordinance to speed plan check. You don't deal with the counter or the corrections — we do.
Yes, and it's one of the most cost-effective paths in Beverly Hills. These homes have detached or attached garages that convert well into a legal ADU — we upgrade the foundation and slab as needed, frame new walls, add insulation, windows, a full kitchen and bath, and bring electrical and plumbing to code, all on permit. A garage conversion typically costs less than a ground-up detached unit.

A garage conversion never needs replacement parking under state ADU law. A new detached unit needs no parking space when the lot is within half a mile walking distance of public transit; parts of Beverly Hills sit outside that zone, so we check the parcel. Where a space is required, one tandem space on the existing driveway satisfies it.

A garage conversion or JADU takes 6–10 weeks of design and plan check and 3–5 months of construction, about 5–8 months in all; a detached ADU takes 3–5 months of design, engineering and plan check and 6–9 months of construction, 9–14 months to the Certificate of Occupancy. Yes, you can rent it: a standard ADU can be rented long-term (30 days or more) with no owner-occupancy requirement; only a JADU requires the owner to live on the property.

Right Image Builders, a licensed general contractor (CSLB #1021284) based in Valley Glen about 25–35 minutes from Beverly Hills, designs, permits and builds ADUs across the Flats north of Santa Monica Boulevard, Trousdale Estates, the hillside streets north of Sunset under one fixed-price contract: design, permits through the City of Beverly Hills, and construction by one crew, with final payment only after your walkthrough. 5.0★ on Google (45 reviews) and 4.9★ on Angi (103 reviews).
