If you’re looking for ADU Builders who understand Beverly Hills plan check, you’ve found the right crew. We build detached ADUs, garage conversions, and studio units across the 90210, 90211, and 90212 zip codes, from the flats north of Santa Monica Boulevard up to the Hillside Overlay boundary. Beverly Hills runs its own building department and its own design review, which means the permit path here is nothing like unincorporated LA County. We know that path, we price it in writing before we start, and we stand behind the finished unit for a full year. Call (361) 315-4177 to schedule a free estimate.
Why Fielding ADU Builders Is Beverly Hills’s Preferred ADU Builders Company

Beverly Hills homeowners call us because we do not treat their ADU like a standard Los Angeles County project. The city has tighter setbacks, a Hillside Overlay exclusion, and a discretionary design review step that catches a lot of builders off guard. Reed Calloway runs our Beverly Hills work personally, and his instruction to every crew is simple: document the site before you quote it. That means checking the Hillside Overlay boundary, locating the sewer lateral, and confirming the street-facing elevation before a single number goes on paper.
We work from a fixed, written price that covers the scope we agreed on. That price goes to you before any work starts, with no exceptions. Our crews arrive background-checked and in uniform, and every job is covered by the Garrison Standard: a written one-year guarantee on workmanship. If something fails inside that year, we come back and make it right at no charge. A live person answers our phone 24 hours a day, seven days a week, whether you call at noon or midnight.
Beverly Hills clients also value that we do not farm out plan check coordination. We handle the city submittal, the Planning Commission design review response, and every inspection from foundation through final. You are not emailing the building department yourself. That coordination is part of why homeowners on streets like North Maple Drive and Roxbury Drive keep referring us to neighbors.
ADU Contractor in Beverly Hills
An ADU Contractor in Beverly Hills does more than frame walls and pour footings. The contractor is responsible for getting the project through the city’s plan check, scheduling inspections with Beverly Hills’s own building department, and making sure the finished unit matches what Design Review approved. Our role starts before construction: we survey the lot, map the Hillside Overlay boundary, locate the existing sewer lateral, and confirm the setback envelope. Then we build the unit and carry it through closeout.
Permit and Plan Check Coordination
Beverly Hills runs its own building department, separate from LA County. The city’s ADU ordinance prohibits units in the Hillside Overlay and requires a minimum 4-foot rear and side setback in most zones. Anything visible from a public street in the flats can trigger discretionary design review. We prepare the submittal to match the city’s requirements from day one, which avoids the 6 – 10 week delay and redesign risk that comes from submitting a standard LA County footprint.
Construction and Closeout
Once the permit is issued, we build to the approved set. You get a fixed schedule with milestones for excavation, foundation, framing, mechanical, and finishes. We pull every inspection, walk each one with the inspector, and fix any correction within days, not weeks. The project closes with a signed final and a unit that is ready for a separate utility meter if you want one.
ADU Design in Beverly Hills

ADU Design in Beverly Hills has to satisfy more than the building code. It has to satisfy the city’s design review, which means the proposed building must respect the look and scale of the neighborhood, especially on street-visible elevations. We design every unit to clear Beverly Hills plan check the first time, then translate that design into a build we can price and guarantee in writing. The cost of design and plan set preparation for a Beverly Hills ADU typically runs $8,000 – $18,000 depending on complexity and whether the project requires Planning Commission-level design review.
Street-Facing Elevations
If your ADU is visible from the public street, the city wants to see materials, color, and roofline that work with the main house. That is a discretionary review, not just a code check. We build the elevation drawings to match the architectural vocabulary of the neighborhood, including the stucco-and-trim palette common in the Beverly Hills flats. The design set goes in as a complete, city-ready package.
Hillside and Setback-Sensitive Lots
Sloping lots and Hillside Overlay boundaries change what you can build. We design the footprint around the actual setback envelope and the sewer lateral, not a catalog dimension. That early design discipline prevents mid-permit redesigns and change orders. You get a footprint that is buildable and priced before we dig.
Trusted Brands We Service in Beverly Hills
We work with leading prefab and modular ADU platforms including Abodu, Cover, and Plant Prefab, along with conventional builds using James Hardie siding. Beverly Hills clients often ask whether a prefab unit will pass design review here; it can, if the factory panel dimensions and finish treatments are chosen to satisfy the city’s street-facing requirements. We coordinate with the manufacturer on site tolerances, utility connections, and foundation details so the unit lands on schedule. We stock common James Hardie trim profiles and panel accessories used on Beverly Hills projects, which keeps turnaround tight when a design review condition calls for a last-minute finish change.
Common ADU Builders Problems We See in Beverly Hills Homes
- The Hillside Overlay surprise. A homeowner pays for a footprint survey from a builder who never checked the boundary, then learns mid-permit that the planned location is excluded. We confirm the overlay boundary during the first site visit, before we quote.
- The sewer lateral in the wrong place. Older Beverly Hills lots often have sewer laterals running under the only logical ADU site. Relocating one can add $12,000 – $25,000. We map the lateral before the footprint is final.
- Street-facing design review gets skipped. A builder quotes a flat catalog unit, and the city sends it to discretionary review. That adds weeks and can force a material change. We design to the review requirements from the start.
- Change orders on sloping lots. Soils on Beverly Hills hillside lots sometimes require deeper caissons, retaining walls, or a dewatering plan. If the builder did not test soil before quoting, the owner pays the difference. We price foundations only after site-specific soils are known.

FAQs About ADU Builders in Beverly Hills
No. Beverly Hills runs its own building department and its own ADU ordinance, which is more restrictive than the state baseline. The city prohibits ADUs in the Hillside Overlay and requires a minimum 4-foot rear and side setback in most zones. Street-visible units in the flats can trigger discretionary design review. A footprint that is legal in unincorporated LA County may not be legal in Beverly Hills. Call (361) 315-4177 and we will check your lot against the city’s rules before you spend a dollar on design.
Budget 10 – 16 weeks for plan check and design review in Beverly Hills, and longer if the first submittal misses a city-specific requirement. The city’s discretionary review step can add 6 – 10 weeks on street-visible projects. Our submittals are prepared specifically for Beverly Hills, which shortens that window. Call (361) 315-4177 for a realistic timeline based on your specific lot.
The biggest cost drivers are site conditions and the city’s design review. Hillside or sloping lots add foundation cost: deeper caissons, retaining walls, or dewatering plans. A sewer lateral that runs under the build area can cost $12,000 – $25,000 to relocate. Street-facing elevations that go through discretionary review can force a higher-spec siding or trim package. We price in writing only after these factors are known. Call (361) 315-4177 for a free estimate.
Yes, you can use a prefab or panelized ADU in Beverly Hills, as long as the unit’s dimensions and finish treatments pass the city’s plan check and any street-facing design review. We coordinate directly with manufacturers like Abodu, Cover, and Plant Prefab on foundation details, utility connections, and site tolerances. The key is choosing the right model for your setback envelope and elevation requirements. Call (361) 315-4177 to talk through which platform fits your lot.
The only thing that changes the price once work begins is a change you make to the scope. Our written price covers the approved plans and the agreed scope, and we do not issue change orders for conditions we should have identified in site documentation. That is why we map the sewer lateral, confirm the Hillside Overlay boundary, and check soils before quoting. If you add square footage or upgrade finishes mid-build, the change order is written and approved by you before we proceed. Call (361) 315-4177 to get your project priced properly the first time.
