You may need a permit in Las Vegas if you add space, open walls, or change plumbing, electrical, gas, or air conditioning. You usually do not need one for painting, flooring, cabinets, countertops, or like for like fixture swaps.
Rules differ by city, and a guide cannot replace a call to your building department. This guide uses the City of Las Vegas homeowner guide and the Clark County building code. Use it to know what to expect before you hire anyone.
A Simple Test: When Do You Need a Permit?
The City of Las Vegas gives four simple rules. You likely need a permit when you:
- Add to a building or build a new structure
- Open up interior or exterior walls
- Work on plumbing, electrical, or mechanical systems beyond routine maintenance
- Turn an existing room, garage, or patio into something new
If any of these fit your project, call your building department before you start.
Who Issues Your Permit? City or County
A Las Vegas mailing address does not always mean the City of Las Vegas. Many addresses sit in unincorporated Clark County. Your permit comes from the office that covers your property.
Not sure which office covers you? Look up your parcel on the Clark County Assessor website, or call the City of Las Vegas Building and Safety Division at 702-229-6251. We can also confirm it for you when you call.

Permit Rules for Common Projects
Easy Mistakes That Trigger a Permit
Moving the sink. Swapping a sink in the same spot is fine. Moving it means new piping, and that needs a permit.
Adding outlets. Replacing an outlet like for like is exempt. Adding one, or adding a required GFCI outlet, needs a permit.
Venting a fan or range hood. Installing vented bath fans and range hood exhausts is listed as permit work.
Changing what a room is for. Turning a garage into a bedroom is a conversion. It needs a permit, plus proper exits and ventilation.
What Happens If You Skip a Required Permit?
Skipping a permit can cost far more than the permit itself.
- You may get a stop work order and investigation fees.
- Inspectors may require engineering reports, testing, and opening finished walls.
- Your insurance company may not cover problems caused by unpermitted work.
- Nevada sellers must disclose known defects, and unpermitted work counts.
- Appraisers often cannot count unpermitted square footage, which can hurt a sale.
- You can usually permit the work after the fact, but fees are higher.
Who Pulls the Permit?
A licensed contractor normally pulls the permit and schedules the inspections. Your contract should say who does it. Be careful with anyone who says you do not need a permit when you do.
Nevada lets a homeowner build or improve their own home for their own use without a contractor license. If you sell or lease the property within one year of finishing, the state may question that exemption. Check any contractor license with the Nevada State Contractors Board before you sign.
How to Get a Permit in Las Vegas
- Confirm which office covers your address.
- Ask that office whether your project needs a permit.
- Prepare drawings if the office requires them.
- Submit your application through the online permit portal for your city or the county.
- Pay the plan review and permit fees.
- Post the permit on site and schedule each inspection.
HOA approval is separate from a building permit. Get both before you start. Permit fees depend on project value and location, and new homes and additions also carry impact fees. To budget for them, use our home construction cost calculator.
