Beverly Hills is not like the rest of Los Angeles County when it comes to building. The city has its own building department and its own Architectural Commission, and that changes everything about how an addition gets permitted, approved, and built. We know that process because we’ve been through it on Spanish Colonials south of Santa Monica Boulevard and on hillside estates north of Sunset. If you’ve been burned by a contractor who quoted LA City timelines and then went silent when the Beverly Hills design review cycle pushed everything back, we’d like to show you what a written plan actually looks like.
Key Takeaways:
- A home addition in Beverly Hills runs $85,000 to $240,000 depending on scope, lot conditions, and permitting requirements.
- Beverly Hills has its own building department and Architectural Commission, separate from LA City, which affects permit timelines and submittal packages.
- Every Lodgewick project includes a written price before work begins and the 365-Day Done Right Promise in writing.
- Russ Delmar leads our team, and a live person answers calls 24/7 at (254) 602-5618.
Why Lodgewick ADU Builders Is Beverly Hills’s Preferred Home Addition Contractor Company
We’re the Home Addition Contractor team homeowners call after they’ve been through a bad remodel or watched a neighbor’s addition stall in permitting for eight months. Russ Delmar leads our projects with one rule: the price you see in writing is the price you pay, and if something changes, you approve the change in writing before we touch a stud. That’s The Kingswell Way, and it’s been the standard since the company started in 2010 as part of the Kingswell family of home-service companies.
Our work across Beverly Hills has taught us the local patterns: the 1920s Spanish Colonials in the flats, the Tudor homes with detached garages built when a two-car garage was considered spacious, the hillside properties north of Sunset where a soils report can save or sink a project budget. Whether you’re in the flats near Wilshire or up in the hills near Coldwater Canyon, the crew arrives in uniform, background-checked, and on the schedule we gave you.
Every project carries the 365-Day Done Right Promise. If the work isn’t right, we come back and make it right, and we put that commitment in writing on every build. There’s a live person answering our phones around the clock, so if you have a question about your permit, your timeline, or your guarantee at 11 p.m., you’ll talk to a human, not a voicemail.
Bedroom Addition Contractor in Beverly Hills
A bedroom addition in Beverly Hills runs $95,000 to $165,000, and the final figure depends heavily on what’s behind the walls of the existing structure and whether your lot is flat or on a hillside. When a homeowner on a 7,500 to 15,000 square foot flat lot south of Santa Monica Boulevard wants to add a bedroom over a detached garage, we start by opening the wall, not by guessing at a number.
Older Beverly Hills homes hide things. Cloth-wrapped knob-and-tube wiring. Framing ledgers notched far past what today’s code allows. Roof-to-wall flashing that’s been quietly leaking into the top plate for decades. Once the permit triggers a Title 24 upgrade and an inspector looks at the opened wall, the scope changes. We handle that by writing an electrical allowance and a framing-repair allowance into the contract from day one. If the inspector flags something, we price the changed condition in writing and get your signature before we proceed. No surprise line items at the end.
What a Bedroom Addition Involves
A bedroom addition on a Beverly Hills home typically means new framing, subfloor, insulation, drywall, electrical runs, and a window package that matches the architectural style of the house. On a Spanish Colonial, that means arched openings and clay tile or flat roof details that fit the original design, not a generic box bolted onto the side. The Architectural Commission looks at materials, massing, and roof lines, so we prepare the submittal package accordingly.
When a Beverly Hills Homeowner Needs One
Most bedroom addition calls we get in Beverly Hills come from growing families who don’t want to leave their neighborhood, or from homeowners who bought a house with an existing guest structure that was never permitted as habitable space. Legalizing that space under California’s ADU streamlining statutes is a different job than a ground-up addition, and it’s why many homeowners turn to ADU Builders in Beverly Hills who know this specialty. Both paths start with the same thing: an honest look at the existing structure.
Sunroom Addition in Beverly Hills
A sunroom addition in Beverly Hills runs $70,000 to $130,000, with higher-end glass packages and engineered foundations pushing toward the top of that range. The mild Southern California climate means sunrooms here get year-round use, but that also means heat gain through glass is a real design problem, not an afterthought. We spec low-E glazing and proper ventilation so the room is usable in August, not just in January.
Sunrooms face a version of the same question bedrooms do: what’s the existing structure hiding? An older home in the flats or a guest cottage that was never permitted often has undersized headers above door openings and no shear wall where the sunroom connects to the main structure. On hillside properties north of Sunset, the expansive clay soils and the documented slide history in the area mean a sunroom addition usually triggers a geotechnical soils report and an engineered foundation. That’s a cost flat-lot garage conversions never see, and it’s one reason a quote from a contractor who only knows LA City pricing will be wrong for your property.
Sunroom Design That Passes Review
The Beverly Hills Architectural Commission reviews sunroom additions for design compatibility with the existing home and the surrounding streetscape. Glass-heavy rooms on the front elevation tend to draw more scrutiny than a matching-roof sunroom on the rear, so we help homeowners think through where the room sits on the lot and how it reads from the street. A well-placed sunroom that matches the home’s style clears review faster than a bold glass box.
Value of a Sunroom in Beverly Hills
A properly permitted sunroom adds livable square footage and resale value in a market where square footage on a Beverly Hills lot is at a premium. The key word is properly permitted. Unpermitted sunrooms become a liability at sale and often have to be torn out or legalized before escrow closes. We build them right the first time, with permits pulled, inspections passed, and a written guarantee on the work.
Trusted Brands We Service in Beverly Hills
We work with established ADU and addition brands and materials including Abodu and Cover for homeowners who want a prefabricated path, and we’re hands-on with James Hardie siding where the Architectural Commission asks for a specific cladding profile. Our familiarity with these brands means we can tell you honestly whether a prefab approach will clear Beverly Hills design review on your lot or whether a site-built addition is the faster path. For Beverly Hills customers, we coordinate material deliveries, submittal drawings, and installation, so you’re not managing a brand on one side and a contractor on the other. You get one team, one written price, and one guarantee.
Common Home Addition Contractor Problems We See in Beverly Hills Homes
- Bidding without opening a wall first. A contractor walks the property, gives a number, and then finds knob-and-tube wiring or a notched framing ledger after demolition. The change order blindsides the homeowner, and the project stalls while everyone argues about who pays.
- Treating Beverly Hills like LA City. A contractor who’s fluent in LA City’s ADU process skips the Beverly Hills Architectural Commission submittal package. The permit stalls, the approval timeline doubles, and the client is told “it’s just how the city is” when the real problem was incomplete paperwork.
- Assuming flat-lot pricing on hillside property. North of Sunset Boulevard, the steep terrain and expansive clay soils documented for slide activity mean a geotechnical report and engineered foundation are often mandatory. A contractor who priced your project like a flat-lot garage conversion is about to hand you a bill for tens of thousands more.
- Skipping the waterproofing details. Beverly Hills homes built in the 1920s through 1950s often have roof-to-wall flashing that’s been failing for years. Skip the flashing repair, and the new addition starts leaking into the framing you just paid to build.

FAQs About Home Addition Contractor in Beverly Hills
Yes, it often does, and that’s exactly why we write electrical and framing-repair allowances into the contract before we start. When you open a wall in a 1920s to 1950s Beverly Hills home, the permit triggers current code requirements, and an inspector will look for things like knob-and-tube wiring, undersized framing, and missing shear wall. We opened up a 1940s Spanish Colonial in the flats south of Santa Monica Boulevard to add a bedroom and sunroom over a detached two-car garage, and the first inspection turned up cloth-wrapped knob-and-tube wiring feeding the garage, a framing ledger notched past code, and a roof-to-wall flashing that had been leaking into the top plate for years. We priced the changed conditions in writing and got the homeowner’s signature before we touched a stud. Call (254) 602-5618 and we’ll do the same for your project.
Beverly Hills is an independent municipality with its own building department and Architectural Commission, and the design-compatibility review California’s state ADU preemption has not fully eliminated adds a submittal cycle LA City projects don’t face. A contractor who’s unfamiliar with the ARC submittal package and the revision cycle will underbid the approval timeline every time. We prepare the full package before we submit, including elevation drawings that address the commission’s typical concerns about massing, materials, and roof lines, so your project doesn’t get bounced back for avoidable reasons.
Expect the possibility of cloth-wrapped knob-and-tube wiring, framing that doesn’t meet current code, and roof-to-wall flashing that’s been leaking for years. The flats south of Santa Monica Boulevard are lined with 1920s to 1950s Spanish Colonial, Mediterranean Revival, and Tudor homes, and their detached two-car garages were built long before modern electrical and structural codes. We write allowances for electrical and framing repairs into the contract from day one, so when the inspector flags something, you already have a budget line for it. The alternative is a contractor who hands you a surprise change order and the project stalls.
Very likely yes. The hillside neighborhoods north of Sunset sit on steep terrain underlain by expansive clay soils with documented historical slide activity, and new detached additions there routinely require a geotechnical soils report and an engineered foundation. That’s a cost and timeline burden flat-lot garage conversions in the flats typically avoid entirely, and it’s one of the first things we check when we walk your lot and review your survey. Call (254) 602-5618 for an estimate that accounts for your actual site conditions, not a flat-lot template.
Yes, and this is a large and recurring project type in Beverly Hills. Many of the larger hillside estates north of Sunset feature existing pool houses or detached guest structures that were built for personal use but never permitted as habitable dwelling units. Bringing those structures into compliance under California’s ADU streamlining statutes means upgrading electrical, installing proper insulation, addressing structural deficiencies, and clearing the Beverly Hills design review process. We’ve done this work, we know where the friction points are, and we’ll price it honestly before we start. Get your free estimate by calling (254) 602-5618.
