In the Las Vegas Valley, the building department that handles your permit depends on where your home sits, not on the city name in your mailing address. Many homes with a “Las Vegas” address are in unincorporated Clark County. Getting this right first saves time, because each office has its own portal, forms and inspection scheduling.
Key takeaways
- Homes inside city limits go to that city’s building department.
- Homes in unincorporated areas go to Clark County.
- Confirm your jurisdiction before you apply, then use that office’s forms and portal.
The main building departments
| Office | Covers | How to apply |
|---|---|---|
| City of Las Vegas Building & Safety | Homes within Las Vegas city limits | Online through the city’s permit dashboard |
| City of Henderson Building and Fire Safety | Homes within Henderson city limits | Online through the Development Services Center portal |
| Clark County Building Department | Unincorporated areas of the county | Online through the county’s citizen access portal |
| City of North Las Vegas | Homes within North Las Vegas city limits | Through the city’s building department |
How to tell which one is yours
A Las Vegas mailing address is not proof: Clark County’s own pages list places in unincorporated towns such as Paradise with Las Vegas addresses, and the county publishes maps of its unincorporated towns. The simplest check is to call the building department you think applies and give your address. The City of Las Vegas homeowner guide lists its Building & Safety staff and phone line for exactly these questions, and Clark County publishes its Building Department contact details on its permit pages.
What is similar everywhere
The broad rules are similar across the valley. Clark County’s code requires a permit to construct, enlarge, alter, repair or demolish a building, or to install, alter or replace electrical, gas, mechanical or plumbing systems. The City of Las Vegas uses the same basic triggers. Both exempt painting, cabinets, countertops, floor coverings and similar finish work. See When You Need a Building Permit in Las Vegas.
What can differ
- The online portal and account you use to apply.
- Details of exemptions, such as the size limits for fences and small walls.
- Standard designs available for common projects.
- Forms, such as owner-builder paperwork and site plans.
- How and when you schedule inspections.
Henderson specifics
Henderson explains that a project may need one or more permits, including building, electrical, mechanical, plumbing or remodel permits. It publishes standard designs for common projects such as patio covers and walls, and its patio cover application refers to preapproved engineering. Owner-builders in Henderson use an Owner Builder Affidavit of Exemption, a Contractors Board form tied to Nevada’s owner-builder law.
Clark County specifics
Clark County’s Building Administrative Code lists permit exemptions in section 22.02.190. Examples include finish work, small one-story storage sheds without mechanical or plumbing, some fences and low walls, and same-size door and window replacements that do not change the framing. The code also notes that an exemption from a permit does not allow work that violates the codes.
Tip: Save the building department’s name, portal link and your permit numbers on the first page of your project binder. You will need them for inspections and for the final record.
If a contractor does the work
A licensed contractor usually knows the local office and handles the application. The Contractors Board advises homeowners to make sure the permit is obtained before work starts and posted on site, and not to pull it themselves. Ask to see the permit and keep a copy.
HOAs are separate
Many Las Vegas neighborhoods have homeowners associations with their own architectural review. HOA approval does not replace a building permit, and a permit does not replace HOA approval. Check both before exterior work such as patio covers, walls or landscaping.
Plans and drawings
Small projects may need only an application and a simple site plan, while additions, conversions and structural changes usually need drawings. Henderson notes that plans prepared by a licensed professional must be sealed or stamped, and plans drawn by a homeowner must be signed on each page. The City of Las Vegas guide adds that more complex projects, such as room additions or conversions, may require detailed construction plans. Ask your office what it needs before paying anyone to draw plans.
Keep your own copy of everything
Whichever office covers your home, save the permit number, the approved plans and every inspection result. The City of Las Vegas guide ends with a simple reminder to always get copies of permits and inspections for your records. These documents become part of your home’s history and are useful when you insure, refinance or sell.
Common mistakes
The most common mistake is applying to the city when the home is in the county, or the other way around. Another is assuming a neighbor’s permit experience applies to your address.
