Plans, Permits & Design in Brentwood
Architectural drawings, structural engineering, Title 24 and full permit management. Designed, permitted and built by our own crews.
Plans, Permits & Design built for Brentwood properties
There are really two build conditions here. On the flat park-district streets we work around mature protected sycamores and oaks whose root zones decide where a pool shell can land. Up in Mandeville, Kenter and Sullivan canyons, single-lane roads and fire-zone construction requirements drive the schedule, and every cubic yard of exported soil has to leave on a route the city has already approved. We price both realities separately.
Broad, level, deeply landscaped lots in the flat park district, transitioning to long, narrow canyon parcels with steep side slopes and single-lane frontage.
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 and insured, LIC #1119054.
Permits in Brentwood: Permits are issued by LADBS, since this is part of the City of Los Angeles rather than a separate city. Hillside lots north of Sunset fall under the Baseline Hillside Ordinance (No. 184,802) for height, floor area and grading limits, and import or export of more than 1,000 cubic yards in a hillside grading area triggers a haul route hearing before the Board of Building and Safety Commissioners. The canyons are mapped Very High Fire Hazard Severity Zone, which brings Chapter 7A ignition-resistant construction and brush clearance obligations. The city's protected tree and shrub ordinance (No. 186,873) covers oak, western sycamore, Southern California black walnut and California bay laurel, plus toyon and Mexican elderberry.

Local Conditions
What building in Brentwood actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Brentwood projects.
Flat park-district lots carry mature sycamores, oaks and walnuts whose protected root zones frequently dictate where a pool shell, footings and utility trenching can go.
Canyon properties north of Sunset sit on single-lane roads with limited turnarounds, so concrete, crane and soil-export days have to be reserved well in advance.
Soils shift from expansive clay to shallow bedrock within a few hundred feet, which changes excavation cost and foundation design substantially between neighboring lots.
Mid-century canyon homes often retain original service panels and galvanized water lines that need upgrading before pool equipment, spa heaters and outdoor kitchens are added.
Investment
What this costs in Brentwood
Real Southern California ranges, not a teaser number. Every project is priced line by line after we have seen the site.
Plans, drawings and permit management
$4,500 to $25,000+
What moves it: project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved
Detached ADU
$150,000 to $400,000+
What moves it: square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build
Retaining walls
$60 to $150 per face foot
What moves it: height, whether the wall is engineered, material choice, drainage behind the wall, and access for equipment and materials
How We Build
Your Brentwood project, step by step
Feasibility
We check zoning, setbacks, easements and utilities to confirm what the property will actually support before you spend on drawings.
Survey & As-Builts
The site and existing structure are measured and drawn so the permit set starts from reality, not an old plot plan.
Design Development
Plans and elevations developed to the level of detail plan check expects, with 3D so you can see it clearly.
Consultants
Structural engineering, Title 24 and, where the site needs it, a soils report are coordinated into one set.
Submittal
We make the submittal and act as the applicant, so correspondence with the city comes to us rather than to you.
Corrections & Issue
We respond to plan-check corrections, resubmit, and see the permit through to issue.
Brentwood Questions
Common questions from Brentwood homeowners
Who issues the permits for this work in Brentwood?
Los Angeles Department of Building and Safety (LADBS). Permits are issued by LADBS, since this is part of the City of Los Angeles rather than a separate city. Hillside lots north of Sunset fall under the Baseline Hillside Ordinance (No. 184,802) for height, floor area and grading limits, and import or export of more than 1,000 cubic yards in a hillside grading area triggers a haul route hearing before the Board of Building and Safety Commissioners. The canyons are mapped Very High Fire Hazard Severity Zone, which brings Chapter 7A ignition-resistant construction and brush clearance obligations. The city's protected tree and shrub ordinance (No. 186,873) covers oak, western sycamore, Southern California black walnut and California bay laurel, plus toyon and Mexican elderberry. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.
What makes building in Brentwood different?
Broad, level, deeply landscaped lots in the flat park district, transitioning to long, narrow canyon parcels with steep side slopes and single-lane frontage. In practice that means flat park-district lots carry mature sycamores, oaks and walnuts whose protected root zones frequently dictate where a pool shell, footings and utility trenching can go..
Which parts of Brentwood do you work in?
All of it, including Brentwood Park, Mandeville Canyon, Kenter Canyon, Sullivan Canyon. We are based in Los Angeles at Cahuenga Pass, so Brentwood is a short run for our crews rather than a job we service from out of the area.
What does plans, permits & design cost in Brentwood?
Plans, drawings and permit management in this market generally runs $4,500 to $25,000+. What moves it is project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved. We give line-item pricing after seeing the site rather than quoting a number over the phone.
Can you do the plans without doing the build?
Yes. Plans and permits is a service we sell on its own, and plenty of clients use us for the drawing set and permit management and build with someone else. We would rather do it properly than tie it to a construction contract.
Why do permit costs vary so much?
Because the required consultants vary. A straightforward patio cover needs a modest set. An ADU on a sloped lot may need structural engineering, Title 24, a soils report and a survey, and each of those is a separate specialist fee on top of the city's own plan-check and permit charges.
What causes plan-check corrections?
Most commonly incomplete structural detail, missing Title 24 forms, drainage not shown, or a discrepancy between the site plan and the survey. Corrections are normal, not a failure. The thing that costs time is a slow response to them, which is why we act as the applicant.
Do you handle HOA approval too?
Yes, where a community requires it. HOA architectural review runs on its own calendar and its own standards, entirely separately from the city, and starting it late is one of the most common reasons a project slips.
