Fast, Reliable Garage Conversion Contractor Across Beverly Hills
A Beverly Hills Home Addition Contractor like us typically prices garage conversion at $140,000 to $240,000 for a full ADU with kitchen and bath, and $90,000 to $160,000 for a simpler garage-to-bedroom conversion. Permitting through Beverly Hills’s own building department and Architectural Commission adds 4 to 9 months before construction starts, which most homeowners don’t plan for. We’ve worked through that process enough times to know where the delays hide and how to price them honestly up front. If you’re weighing a conversion on a flat lot south of Santa Monica Boulevard or a hillside property north of Sunset, call (254) 602-5618 for a written, line-item estimate before you commit to anything.
Why Lodgewick ADU Builders Is Beverly Hills’s Preferred Garage Conversion Contractor Company
Our Garage Conversion Contractor team has shepherded conversions through Beverly Hills’s Architectural Commission review more times than we can count, and that matters here more than almost anywhere else in Southern California. The city runs its own design-review process, separate from LA City, and a contractor who doesn’t know the ARC submittal package by heart will underbid the timeline every single time.
Russ Delmar leads the crew that has converted detached garages behind 1920s Spanish Colonials, pool houses on estate lots north of Sunset, and everything in between. The Kingswell Guarantee is the same on every project: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee covering the work for 365 days. If something isn’t right, we come back and make it right. That’s not a sales line. It’s in the contract.
We also answer the phone. A live person picks up 24 hours a day, seven days a week. When you’re mid-project and the Architectural Commission kicks back a revision, you don’t want a voicemail loop. You want someone who can tell you what to send and when.
Garage to Bedroom Conversion in Beverly Hills
Garage to Bedroom Conversion in Beverly Hills is the most common project we take on south of Santa Monica Boulevard, where 1920s through 1950s homes on 7,500 to 15,000 square foot lots almost always have a detached two-car garage that’s underused. Homeowners typically want a private guest suite, a home office with a separate entrance, or a room for an aging parent that keeps them close without giving up privacy. A garage-to-bedroom conversion in Beverly Hills runs $90,000 to $160,000 depending on whether you’re adding a bathroom, how much electrical work the old structure needs, and whether the foundation can stay as-is.
What the permit opens up
A 1940s garage on the flats almost always hides cloth-wrapped wiring, undersized framing, and roof decking that was never meant to be lived under. Building code triggers a rewire, likely shear-panel or hold-down upgrades, and insulation and drywall from scratch. We write an allowance for these code upgrades into the contract before we open a single wall, so the price you sign is the price you pay, and any discovery gets priced and approved in writing before we touch it.
Flat lots vs. hillside lots
The flats are forgiving. A standard slab or shallow foundation usually works. North of Sunset, the clay soils change the equation entirely. If the garage sits on a hillside, Beverly Hills building officials often require a geotechnical soils report and an engineered foundation, which can add $30,000 to $60,000 to the total before framing even begins. We’ll tell you which situation you’re in during the first site visit.
Garage Conversion ADU in Beverly Hills
Garage Conversion ADU in Beverly Hills means turning that detached or attached garage into a fully permitted accessory dwelling unit with its own kitchen, bathroom, entrance, and address. This is the project type where the city’s Architectural Commission review matters most. The ARC asserts design-review authority over ADU projects even where state law limits local aesthetic restrictions, which means you’re submitting a separate design package and going through revision rounds that an LA City-only contractor has never had to manage. A garage conversion ADU in Beverly Hills runs $140,000 to $240,000, with the higher end covering hillside foundations, custom exterior finishes the ARC will approve, and high-end interior fit-out.
Design compatibility is real here
The ARC cares how the ADU reads from the street. A boxy prefab dropped behind a 1930s Spanish Revival will get comments. We match rooflines, stucco texture, window proportions, and setback language to the main house so the project clears design review without three extra revision cycles. We work with manufacturers including Cover and Dvele when a panelized or prefab system fits the lot, and we handle the ARC package either way.
The unpermitted guest structure niche
North of Sunset, we regularly convert pool houses and guest cottages that were built decades ago and never permitted as habitable space. California’s ADU streamlining statutes give Beverly Hills homeowners a legal path to bring those structures into compliance, but it requires as-built drawings, structural verification, and a frank conversation with the building department about what can be grandfathered and what can’t. This is a high-value, recurring project type in Beverly Hills that most contractors never touch.
Trusted Brands We Service in Beverly Hills
We spec and install systems from Mighty Buildings, Boxabl, and Dvele when the project timeline or lot conditions favor prefab over stick-built. We keep materials and lead times local for Beverly Hills customers, which means we’re not waiting on a factory schedule across the country. We’ll tell you honestly when a prefab panel cuts six weeks off a timeline and when a custom stick-built conversion makes more sense for your lot and the ARC’s expectations.
Common Garage Conversion Contractor Problems We See in Beverly Hills Homes
- Underbidding the ARC timeline. A contractor who knows LA City’s ADU process cold can still get blindsided by Beverly Hills’s separate Architectural Commission submittal package and revision rounds. We build the real timeline into the schedule on day one, with the ARC’s specific document requirements itemized in the contract.
- Hidden wiring and framing in older garages. Garages from the 1920s through 1950s on the flats almost always have cloth-wrapped electrical, termite-damaged top plates, or both. We price an allowance for these discoveries in writing before demolition, so the quote doesn’t balloon into a dispute.
- Hillside clay soils north of Sunset. Steep terrain under expansive clay with documented slide history means new detached ADUs need geotechnical reports and engineered foundations. A flat-lot price quoted on a hillside property is a red flag. We walk the lot before quoting and tell you which category you’re in.
- Unpermitted guest quarters on estate lots. Many Beverly Hills properties have pool houses or detached guest structures that were never permitted as dwelling units. Legalizing them under California’s ADU streamlining is a niche process that requires as-builts, structural verification, and a working relationship with the Beverly Hills building department.
Pricing for Garage Conversion Contractor in Beverly Hills, CA
A garage-to-bedroom conversion in Beverly Hills typically runs $90,000 to $160,000. A full garage conversion ADU with kitchen and bath runs $140,000 to $240,000. Hillside lots north of Sunset add $30,000 to $60,000 for soils reports and engineered foundations. ARC design review and revision cycles add 4 to 9 months to the timeline, and we price that time into the schedule rather than letting it ambush you later.
The single biggest variable on older homes is what the permit opens up. Rewiring a 1940s garage, adding shear panels, and replacing termite-damaged framing can run $15,000 to $40,000 on top of base construction, depending on what’s behind the walls. That’s why we write an allowance line into every contract. You get a written price before work starts, a written change order for anything uncovered, and your signed approval before we touch a single stud.

FAQs About Garage Conversion Contractor in Beverly Hills
Cloth-wrapped wiring, undersized or termite-damaged framing, and roof decking that was never meant to be lived under. Most garages from this era were built for cars and storage, not habitation. When the permit opens the walls, Beverly Hills building code requires rewiring, shear resistance, insulation, and new drywall. We write an allowance for these discoveries into the contract before demolition starts, so the cost is visible and approved before work proceeds. Call (254) 602-5618 for an estimate that includes those allowances.
In most cases, yes. Beverly Hills’s Architectural Commission has asserted design-review authority over ADU projects even where California’s state ADU preemption limits local aesthetic restrictions. That means a separate ARC submittal package and revision cycle, on top of the building permit. We prepare the ARC documents ourselves, respond to comments directly, and have cleared enough of these reviews to know what triggers a revision and what passes. For a project timeline that accounts for design review, call (254) 602-5618.
The hillside neighborhoods north of Sunset sit on steep terrain underlain by expansive clay soils with documented historical slide activity. Beverly Hills building officials routinely require a geotechnical soils report and an engineered foundation for new detached ADUs there, which adds $30,000 to $60,000 before framing begins. Flat lots on the flats south of Santa Monica Boulevard usually don’t trigger that requirement. We’ll tell you which situation applies to your property during the first walkthrough.
Usually yes, and this is one of the most common projects we handle on Beverly Hills estate lots. California’s ADU streamlining statutes give homeowners a legal path to bring unpermitted guest quarters into compliance as a legal accessory dwelling unit. The process requires as-built drawings, structural verification, and a clear conversation with the Beverly Hills building department about what can be grandfathered and what must be brought to current code. Call (254) 602-5618 and we’ll assess the structure and tell you what’s realistic.
By writing allowances into the contract before demolition begins, and requiring written approval before any change is made. The single biggest reason a garage conversion quote moves in Beverly Hills is hidden condition: old wiring, termite damage, failed waterproofing. Our process is inspection first, allowance written into the contract, and any surprise priced and approved in writing before we touch a single stud. Call (254) 602-5618 for a free estimate that follows that process from day one.
