ADU Company in Beverly Hills, CA
Beverly Hills is an independent city with its own building department and Architectural Commission, which means ADU work here runs through a permitting process separate from Los Angeles. The homes are older, the lots are large, and the rules are stricter than most contractors expect. We’re Lodgewick ADU Builders, part of the Kingswell family, and we handle accessory dwelling units, garage conversions, and home additions across Beverly Hills. Every project starts with a written price before any work begins. Call (254) 602-5618 to talk through your lot and your options.
Why Beverly Hills Homes Are Different
The residential flats south of Santa Monica Boulevard are lined with 1920s through 1950s Spanish Colonial, Mediterranean Revival, and Tudor homes on lots between 7,500 and 15,000 square feet. Most have detached two-car garages that make natural ADU conversion candidates. North of Sunset Boulevard the terrain changes completely: hillside estates with steep grades, expansive clay soils, and documented landslide history. A new detached ADU up there usually needs a geotechnical soils report and an engineered foundation, which adds cost and time that a flat-lot garage conversion in the flats avoids entirely.
Then there’s the Architectural Commission. Beverly Hills’s ARC asserts design-review authority over ADU projects even though state law limits local aesthetic restrictions. A contractor fluent in LA City’s ADU process but unfamiliar with Beverly Hills’s separate ARC submittal package and revision cycle will underbid the approval timeline every time. We know the submittal package, the revision cycle, and how to write a project description that moves through design review without stalling.
The dominant project type here is legalizing or converting an existing pool house, detached garage, or guest cottage that was built decades ago and never permitted as a dwelling unit. That’s a different job than ground-up construction. It means as-built documentation, correction plans, and a clear path through California’s ADU streamlining statutes. We do that work regularly because the estate lots north of Sunset are full of those structures.
Our Main Beverly Hills Services
Most Beverly Hills homeowners call us about one of three things: adding square footage to the main house, converting a detached garage into livable space, or building a new ADU from the ground up. Each has its own page with local pricing and details.
Home Addition Contractor in Beverly Hills
Home additions in Beverly Hills mean working within the existing envelope or expanding into rear and side yards that sit inside a strict zoning envelope. On flats lots, additions often tie into the original 1930s framing, which means matching rooflines and foundation types a modern crew rarely sees. In the hills, additions trigger soils and foundation engineering more often than not. We price every addition with a written line-item quote before work starts.

Garage Conversion Contractor in Beverly Hills
Garage conversions are the most common ADU path in the Beverly Hills flats south of Santa Monica Boulevard. Those detached two-car garages from the 1930s and 1940s are already on a foundation and already connected to power, which makes them faster and cheaper than new construction. The catch is the Architectural Commission: exterior changes to a street-facing garage require design review, and we prepare the ARC package as part of the bid.

ADU Builders in Beverly Hills
New detached ADUs on Beverly Hills estate lots are a bigger lift. Hillside sites north of Sunset usually need a geotechnical report, an engineered foundation, and a grading plan before the building department will even look at the permit. Flat-lot sites avoid the soils work but still face the ARC design review. We work with prefab ADU manufacturers like Cover and Dvele when the site and budget fit, and we do stick-built ADUs when the lot demands it. ADU Builders in Beverly Hills

Hillside work north of Sunset pushes prices up because of the soils report, engineered foundation, and grading plan the building department requires. ARC design-review revisions can also add cost if the first submittal isn’t prepared correctly. Every Lodgewick bid is a written, line-item price before any work starts, and that number does not change at the door.

FAQs About ADU Company in Beverly Hills
Yes, in most cases. Beverly Hills’s Architectural Commission conducts design review on ADU projects even though state law limits how much a city can restrict aesthetics. You’ll need a complete ARC submittal package, and revisions can add weeks. We prepare that package as part of every Beverly Hills bid.
Beverly Hills has its own building department and its own permit process. Los Angeles City rules do not apply inside Beverly Hills city limits. The ARC design review layer is the biggest difference, and it catches out contractors who only know LA’s process. Call (254) 602-5618 for an honest read on your specific lot.
