ADUs & Additions in Beverlywood
Detached ADUs, garage conversions, room additions and second stories. Designed, permitted and built by our own crews.
ADUs & Additions built for Beverlywood properties
Beverlywood was developed in 1940 by Walter H. Leimert around Circle Park, and its 1,354 homes remain bound by covenants, conditions and restrictions administered by the Beverlywood Homes Association. Most building projects here answer to two reviewers, LADBS and the association, whose Design Review Committee and board weigh the grading plan, proportions, height and even the color scheme against the neighborhood's established character. Below the tree-lined streets lie the Cheviot Hills and Beverly Hills oil fields, and the methane zoning that reaches most parcels shapes how new rooms and ADUs are built. The association asks owners to expect at least two months for its design review, so the calendar for an addition or an ADU starts well before the first city permit is issued.
Mostly 1940s single-family houses on lots that commonly run from about 6,000 to 8,500 square feet in LA County Assessor parcel data, behind front setbacks where the association prohibits fences and freestanding walls. The CC&Rs require a two-car garage on every lot, and a garage converted to an ADU keeps its garage door wherever that door is visible from the street.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054.
Permits in Beverlywood: Private pools in the City of Los Angeles are permitted through a Combined Building-Mechanical permit, while pools serving more than two dwelling units need separate building, electrical, plumbing and mechanical permits. Using a City of Los Angeles standard plan on file with LADBS reduces plan check time. Beverlywood falls within the city's Hillside Grading Area, where LADBS requires grading plan check and a grading permit for a new pool excavation, and most parcels are also mapped in a Methane Zone or Methane Buffer Zone, which brings new buildings and additions under the city's methane mitigation rules. Single-family lots are zoned R1V2, an R1 Variation Zone whose residential floor area ratio runs from 0.55 on lots up to 6,000 square feet down to 0.45 on lots over 10,000, under a 30-foot height limit. A pool, addition, ADU, grade change or retaining wall also needs approval from the Beverlywood Homes Association, whose rules hold a pool at least five feet from every property line, measured to the water line, and keep the pool equipment in the rear yard.
Permit details checked September 2026 against LADBS and LA City Planning. Rules change, so we confirm them again for your parcel.

Local Conditions
What building in Beverlywood actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Beverlywood projects.
A band of blocks near Robertson Boulevard, including parts of David Avenue and Hillsboro Avenue, lies inside a state Alquist-Priolo Earthquake Fault Zone mapped on the California Geological Survey's Beverly Hills quadrangle, so the fault map is worth checking before an addition or ADU is placed on those lots.
The Cheviot Hills oil field underlies the western blocks and the Beverly Hills oil field the northeastern ones, and the methane zoning over most parcels can mean methane site testing, a sub-slab vent system and a Fire Department clearance for gas detection and ventilation on a new ADU or addition.
When a sloping rear yard is excavated, association rules allow retaining walls only in the rear yard, at least five feet from the side and rear property lines and out of view of any street, capped at one 8-foot wall or two 6-foot walls set at least five feet apart.
A parkway tree can be removed only with prior association Board approval and must be replaced with a 60-inch box tree, so the existing street canopy is a fixed point when truck, pump and crane access is planned.

Beverlywood Questions
Common questions from Beverlywood homeowners
Who issues the permits for this work in Beverlywood?
Los Angeles Department of Building and Safety (LADBS). Private pools in the City of Los Angeles are permitted through a Combined Building-Mechanical permit, while pools serving more than two dwelling units need separate building, electrical, plumbing and mechanical permits. Using a City of Los Angeles standard plan on file with LADBS reduces plan check time. Beverlywood falls within the city's Hillside Grading Area, where LADBS requires grading plan check and a grading permit for a new pool excavation, and most parcels are also mapped in a Methane Zone or Methane Buffer Zone, which brings new buildings and additions under the city's methane mitigation rules. Single-family lots are zoned R1V2, an R1 Variation Zone whose residential floor area ratio runs from 0.55 on lots up to 6,000 square feet down to 0.45 on lots over 10,000, under a 30-foot height limit. A pool, addition, ADU, grade change or retaining wall also needs approval from the Beverlywood Homes Association, whose rules hold a pool at least five feet from every property line, measured to the water line, and keep the pool equipment in the rear yard. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.
What makes building in Beverlywood different?
Mostly 1940s single-family houses on lots that commonly run from about 6,000 to 8,500 square feet in LA County Assessor parcel data, behind front setbacks where the association prohibits fences and freestanding walls. The CC&Rs require a two-car garage on every lot, and a garage converted to an ADU keeps its garage door wherever that door is visible from the street. One local condition that shapes the work: A band of blocks near Robertson Boulevard, including parts of David Avenue and Hillsboro Avenue, lies inside a state Alquist-Priolo Earthquake Fault Zone mapped on the California Geological Survey's Beverly Hills quadrangle, so the fault map is worth checking before an addition or ADU is placed on those lots.
Which parts of Beverlywood do you work in?
All of it, including Monte Mar Drive, Beverwil Drive, Cresta Drive and Duxbury Circle. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What does an ADU or addition cost in Beverlywood?
Detached ADU: generally $150,000 to $400,000+ across Southern California. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does an ADU take start to finish?
Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.
Is a garage conversion cheaper than a detached ADU?
Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.
Can I rent the ADU out?
California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.
Do you handle the permits?
Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
