Plans, Permits & Design in Westlake Village
Architectural drawings, structural engineering, Title 24 and full permit management. Designed, permitted and built by our own crews.
Plans, Permits & Design built for Westlake Village properties
One thing surprises owners here more than anything else: the City handles planning and design review, but building permits and inspections come from Los Angeles County, which Westlake Village contracts with for building and safety. So a backyard project moves through two separate desks. We sequence it that way from the start — City design review first, then County plan check through EPIC-LA — and keep HOA architectural review running alongside.
Mostly planned-development parcels: modest, well-defined rear yards in the older neighborhoods, waterfront lots with dock frontage on the island, and larger slope-backed lots along the hillside edges.
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 Westlake Village: The City contracts with Los Angeles County for building and safety, so plan check, permit issuance and inspections are handled by the County Department of Public Works Building and Safety Division through its Calabasas office and the EPIC-LA online system, while planning and design review stay with the City's Planning Department at City Hall. Design review is required for residential development under the R-1 and RPD standards. Parcels inside the Hillside Management Area pick up slope-specific setbacks, ridgeline protection and grading limits, and most neighborhoods also carry HOA architectural review, with waterfront parcels answering separately to the lake association for dock and shoreline work.

Local Conditions
What building in Westlake Village actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Westlake Village projects.
Lakefront and near-lake parcels sit on filled and reworked ground with shallow groundwater, which changes pool shell design, dewatering and retaining detail.
Hillside Management Area parcels carry slope-based setbacks and ridgeline limits that push outdoor living into stepped terraces rather than a single pad.
Island and cul-de-sac lots have tight street frontage, so excavation spoil, gunite and equipment access frequently require conveyor or crane staging.
Wildland-adjacent slopes on the southern and western edges bring defensible-space obligations directly into the landscape and hardscape plan.
Investment
What this costs in Westlake Village
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 Westlake Village 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.
Westlake Village Questions
Common questions from Westlake Village homeowners
Who issues the permits for this work in Westlake Village?
Los Angeles County Department of Public Works, Building and Safety Division (under contract to the City of Westlake Village). The City contracts with Los Angeles County for building and safety, so plan check, permit issuance and inspections are handled by the County Department of Public Works Building and Safety Division through its Calabasas office and the EPIC-LA online system, while planning and design review stay with the City's Planning Department at City Hall. Design review is required for residential development under the R-1 and RPD standards. Parcels inside the Hillside Management Area pick up slope-specific setbacks, ridgeline protection and grading limits, and most neighborhoods also carry HOA architectural review, with waterfront parcels answering separately to the lake association for dock and shoreline work. 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 Westlake Village different?
Mostly planned-development parcels: modest, well-defined rear yards in the older neighborhoods, waterfront lots with dock frontage on the island, and larger slope-backed lots along the hillside edges. In practice that means lakefront and near-lake parcels sit on filled and reworked ground with shallow groundwater, which changes pool shell design, dewatering and retaining detail..
Which parts of Westlake Village do you work in?
All of it, including Westlake Island, First Neighborhood, Three Springs, Watergate. We are based in Los Angeles at Cahuenga Pass, so Westlake Village 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 Westlake Village?
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.
