Westlake Village has no city building department: the permit comes from Los Angeles County Building and Safety, from the Calabasas District Office of Los Angeles County Building and Safety, 27001 Agoura Road, Suite 250, after a zoning clearance from the City of Westlake Village Planning Department at 31200 Oak Crest Drive, with the application through the County's EPIC-LA portal. A like-for-like re-side or re-stucco is a simpler permit than a conversion or a wall that needs framing repair, which goes to plan check.
Westlake Village contracts with Los Angeles County for building and safety, so the permit, the inspections and the records are the County's while the zoning clearance comes from the City first. The Ventura County side of Westlake Boulevard is the City of Thousand Oaks with a Westlake Village postal address, a different jurisdiction we confirm from the parcel. The lakefront and hillside tracts add HOA review.
We prepare whichever review comes first, submit the permit, schedule the inspections, meet the inspector at the flashing stage and at the final, and close the permit before the final payment. You keep the closed-permit record.
