Bathroom Remodel Permits in the Conejo Valley
Not sure whether your bathroom project needs a permit, or who issues it? Here is how it generally works, and we can connect you with a local contractor who pulls permits.
Most bathroom remodels that move or replace plumbing, add or change electrical circuits, alter walls, or replace a shower pan need a building permit. Purely cosmetic work, such as painting or swapping a mirror, usually does not. The exact rules depend on who has jurisdiction over your address, so confirm with the building department before work starts.
Who issues permits in the Conejo Valley area?
This area spans two counties and several cities, and a mailing address does not always tell you which agency is in charge. In general:
- Thousand Oaks (including Newbury Park and the Westlake neighborhoods inside the city): the City of Thousand Oaks building division.
- Simi Valley, Moorpark, and Camarillo: each city's own building and safety department.
- Unincorporated Ventura County, such as Oak Park, Santa Rosa Valley, Lake Sherwood, Hidden Valley, Bell Canyon, Casa Conejo, and Somis: County of Ventura building and safety, part of the Ventura County Resource Management Agency.
- Westlake Village (the city), Agoura Hills, and Calabasas are in Los Angeles County, and each city handles or arranges its own building permits. Confirm with the city.
The Westlake area is split: the City of Westlake Village is in Los Angeles County, while some neighborhoods with Westlake Village addresses are inside Thousand Oaks city limits in Ventura County. If you are unsure, check your property tax bill or ask the city.
What usually triggers a permit?
- Moving a toilet, shower, tub, or sink drain, or adding a fixture.
- Replacing a shower pan or building a new tiled shower.
- Replacing a water heater, which often happens alongside bathroom work.
- New circuits, new lighting locations, or a new exhaust fan duct.
- Removing or moving walls, widening doorways, or adding windows.
Like-for-like fixture swaps may be exempt in some jurisdictions. Ask rather than assume.
What inspections should I expect?
Typical inspections include a rough plumbing and electrical inspection before walls are closed, sometimes a shower pan inspection, an inspection of insulation or framing if walls changed, and a final inspection. Your contractor schedules these and should not cover work before it passes.
Water-conserving fixtures and other California rules
New toilets, showerheads, and faucets sold in California already meet state water-efficiency limits. California law also generally requires that older noncompliant fixtures be replaced with water-conserving ones when certain permitted alterations are made to homes built before 1994. Bathroom fans in California homes typically need to vent outside, and many jurisdictions expect humidity control. Your contractor and the plan checker can tell you what applies.
HOA approval
Many Conejo Valley neighborhoods, condo complexes, and gated communities have HOAs. Interior bathroom work usually needs no HOA approval in a detached home, but condos and townhomes often require notice or approval, rules about work hours, and proof of insurance from the contractor. Exterior changes, such as a new window, usually need architectural committee approval. Ask your HOA before scheduling.
Why permits are worth it
- An inspector checks work you can't see once the walls are closed.
- Unpermitted work can complicate a sale or an insurance claim.
- A contractor who avoids permits on request may cut other corners too.

Frequently asked questions
Who pulls the permit, me or the contractor?
Usually the contractor, under their license. Owner-builder permits are possible but make you responsible for the work. Be wary of a contractor who asks you to pull the permit yourself.
How long does a bathroom permit take?
It varies by jurisdiction and scope. Some simple projects are approved quickly; projects with layout or wall changes can need plan check. Ask your building department for current timing.
Does my condo HOA need to approve a bathroom remodel?
Often, yes. Many condo associations require notice, approved work hours, and contractor insurance certificates. Check your HOA rules before scheduling.
