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 any 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, bonded and insured, [CSLB license #1119054](https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/LicenseDetail.aspx?LicNum=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. Any permit or zoning clearance for new construction or exterior changes must meet the City's design standards (WVMC 9.15), and uses in the RPD zone need a planned development permit, although alterations to an existing single-family home are exempt (WVMC 9.6.070). Parcels inside the Hillside Management Area must meet the City's hillside development standards, which call for preserving prominent ridgelines and minimizing grading. We also check any HOA CC&Rs for a separate architectural approval. Permit details checked September 2026 against [City of Westlake Village](https://www.wlv.org/163/Building-Safety) and [Westlake Village Municipal Code](https://library.municode.com/ca/westlake_village/codes/code_of_ordinances?nodeId=ART9ZORE_CH9.17HIDEST_9.17.020AP) . Rules change, so we confirm them again for your parcel. What We Build - City design review plus County plan check sequencing - HOA architectural submittals - Lakefront and hillside retaining design - Measured surveys and existing-condition drawings - Permit-ready plan sets for submittal - Structural engineering coordination - Title 24 energy compliance documentation - ADU and addition planning packages - Pool, hardscape and structure permits - Soils and geotechnical report coordination - HOA architectural review submissions - City submittal and plan-check correction responses - Inspection scheduling and sign-off Local Conditions #### What to Know in Westlake Village These local conditions change the scope, the schedule and the budget. 01 Lakefront parcels need a site-specific soils investigation before pool shell and retaining design. 02 Hillside Management Area parcels must preserve prominent ridgelines and minimize grading, which pushes outdoor living into stepped terraces rather than a single pad. 03 Island and cul-de-sac lots have tight street frontage, so excavation spoil, gunite and equipment access frequently require conveyor or crane staging. 04 Wildland-adjacent slopes on the southern and western edges bring defensible-space obligations directly into the landscape and hardscape plan.

Questions #### What Westlake Village Homeowners Ask 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. Any permit or zoning clearance for new construction or exterior changes must meet the City's design standards (WVMC 9.15), and uses in the RPD zone need a planned development permit, although alterations to an existing single-family home are exempt (WVMC 9.6.070). Parcels inside the Hillside Management Area must meet the City's hillside development standards, which call for preserving prominent ridgelines and minimizing grading. We also check any HOA CC&Rs for a separate architectural approval. 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 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. One local condition that shapes the work: Lakefront parcels need a site-specific soils investigation before pool shell and retaining design. Which parts of Westlake Village do you work in? All of it, including Westlake Island, First Neighborhood, Three Springs and Watergate. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site. What do plans and permits cost in Westlake Village? Plans, drawings and permit management: generally $4,500 to $25,000+ across Southern California. 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. #### More Services in Westlake Village [Pool & Spa Remodeling in Westlake Village](https://www.remodelyourvibe.com/services/swimming-pool-spa/westlake-village) [Backyard & Outdoor Living in Westlake Village](https://www.remodelyourvibe.com/services/exterior-remodeling/westlake-village) [ADUs & Additions in Westlake Village](https://www.remodelyourvibe.com/services/adus-additions/westlake-village) [Kitchen, Bath & Interior Remodeling in Westlake Village](https://www.remodelyourvibe.com/services/interior-remodeling/westlake-village) [Everything we build in Westlake Village](https://www.remodelyourvibe.com/service-areas/westlake-village) #### Plans, Permits & Design Nearby [Plans, Permits & Design in Thousand Oaks](https://www.remodelyourvibe.com/services/plans-permits/thousand-oaks) [Plans, Permits & Design in Agoura Hills](https://www.remodelyourvibe.com/services/plans-permits/agoura-hills) [Plans, Permits & Design in Calabasas](https://www.remodelyourvibe.com/services/plans-permits/calabasas) [Plans, Permits & Design in Hidden Hills](https://www.remodelyourvibe.com/services/plans-permits/hidden-hills) Planning Guides #### Before You Build in Westlake Village Costs, materials and process notes from our own projects.
