Usually, yes. In the Las Vegas valley, remodels that change structure, plumbing, electrical, gas, or HVAC generally need a building permit, while cosmetic finish work like paint, flooring, cabinets, and countertops usually does not. Which rules apply depends on whether your address is in the City of Las Vegas, Henderson, North Las Vegas, or unincorporated Clark County.
This guide walks through the work that typically needs a permit, the work that usually does not, who is allowed to pull one, and what happens when work gets done without it. It reflects the published rules of each building department as of October 2026. It is general information, not legal advice, and every building department has the final word on its own projects, so confirm your specific project with the department that covers your address before work starts.
Who Issues the Permit: the City or Clark County?
A Las Vegas mailing address does not tell you which building department you deal with. The valley is split among four permitting jurisdictions, and each one runs its own building department, adopted codes, application portal, and inspectors:
- City of Las Vegas, through its Building and Safety division.
- City of Henderson, through its Building and Fire Safety department.
- City of North Las Vegas, through its Building Safety division.
- Unincorporated Clark County, through the Clark County Department of Building and Fire Prevention.
Unincorporated Clark County covers a large share of the valley. According to Clark County Comprehensive Planning, Spring Valley, Enterprise, Winchester, Paradise, and Summerlin South are all unincorporated towns administered by Clark County. If your home is in one of those areas, your permit comes from the county, not from the City of Las Vegas, even though the address says Las Vegas. When in doubt, check your parcel with the county or call the city building department before you apply.
What Remodel Work Usually Doesn’t Need a Permit?
Clark County publishes its exemptions in the Clark County Building Administrative Code, which the county’s “Do I Need a Permit?” page links to. In unincorporated Clark County, the code does not require a permit for items including:
- Painting, papering, paneling, floor coverings, cabinets, moldings, countertops, and similar finish work.
- Replacing a plumbing fixture in the same location with a similar fixture, when the work is limited to the fixture, tail piece, and trap and does not penetrate fire-rated construction.
- Repairing leaks or clearing stoppages, as long as concealed piping does not have to be replaced or rearranged.
- Replacing receptacles (but not the outlet box) and replacing light fixtures in a single-family home.
- Minor drywall repair of 30 square feet or less, with no framing repair and no multi-layer fire-rated assembly.
- Replacing a door or a window with one of the same size and type, when no wall framing changes and the opening is not part of a fire-rated element. Windows also cannot be ones that are required to have safety glazing.
That is why a new countertop on existing cabinets, new flooring, or fresh paint usually involves no permit at all in the county. Once the job moves a sink, adds a circuit for a new appliance, or opens a wall, it is no longer finish work.
These exemptions are Clark County’s list. The City of Las Vegas, Henderson, and North Las Vegas each adopt and amend their own codes, and their exempt work lists are not always identical. If you live inside one of the cities, check your jurisdiction before assuming the county list applies to you.
What Remodel Work Needs a Permit?
Clark County’s rule is broad. Anyone who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building, or to install, alter, convert, or replace any electrical, gas, mechanical, or plumbing system regulated by code, must first apply for and obtain the required permit. In practice, that covers most remodel work beyond surface finishes:
- Structural work, such as removing or moving walls, cutting new openings, enlarging a window or door, or changing framing.
- Electrical work, such as new circuits, a dedicated circuit for an appliance, added outlets, or a panel change.
- Plumbing work, such as moving a sink, toilet, or shower, adding a fixture, or replacing concealed piping.
- Gas work, such as moving or adding a gas line for a range, dryer, or fireplace.
- Mechanical work, such as replacing or relocating HVAC equipment or ductwork.
A kitchen or bathroom remodel often mixes both kinds of work. New cabinets and countertops on their own may be exempt, while relocating the sink or adding lighting circuits in the same project needs a permit for that part of the job.
Do Water Heater and AC Replacements Need a Permit?
Generally, yes, even when you are swapping like for like. Clark County lists water heaters, water softeners, residential re-pipes, and A/C or furnace replacements under 5 tons among its simple online permits, which are permits that do not need plan review but still have to be obtained and inspected. The county issues one permit per appliance.
The City of Las Vegas takes a similar approach. Its online permits list includes same-for-same water heaters (including tankless), exact HVAC change-outs, panel changes, minor electrical of 12 devices or fewer, and water piping replacement as permits issued without plans. The city notes that any work not on that list requires a plan to be submitted and reviewed.
Do Room Additions, Patio Covers, and Walls Need a Permit?
A room addition enlarges the building, so it needs a permit and usually a full set of plans for plan review. Expect structural, electrical, plumbing, and mechanical work to be reviewed and inspected as the addition goes up. If you are planning one, our room additions page covers how we approach design, permitting, and matching the existing home.
Patio covers are not on Clark County’s exempt list, which only exempts small items like window awnings projecting 54 inches or less and platforms no more than 30 inches above grade. Henderson has a dedicated Residential Patio Cover/Deck Application that asks for the contractor’s Nevada license number, the cover’s dimensions, and setbacks to property lines, and it lists the standard patio cover designs prepared by the Southern Nevada Building Officials among its engineering options.
Walls and fences depend on height and type. In unincorporated Clark County, fencing up to 6 feet high that is not part of a pool barrier, retaining walls no more than 24 inches high, and repairs to block walls 6 feet tall or less that cover no more than 20 linear feet are exempt from a building permit. Taller walls and retaining walls need one. Henderson has its own wall permit application and a property line authorization form for residential walls and fences, so check your jurisdiction.
Is HOA Approval the Same as a Permit?
No. A building permit comes from the city or county and confirms the work meets the building codes. HOA approval comes from your homeowners association and confirms the project meets the community’s own rules. Nevada’s common-interest community law, NRS Chapter 116, recognizes that an association’s governing documents can require owners to submit architectural plans for approval.
The two are separate. A permit does not satisfy your HOA, and HOA approval does not replace a permit. Many homeowners need both, especially for patio covers, room additions, walls, and exterior changes, so read your CC&Rs and ask the association what it requires before you build.
Who Can Pull the Permit: You or a Contractor?
In most cases, a licensed contractor pulls the permit. Clark County issues permits only to contractors who hold an active Nevada State Contractors Board license covering the scope of work, plus a valid Clark County business license. Plumbing, electrical, and mechanical permits go only to specialty contractors holding the matching C-1, C-2, or C-21 license. The main exception is a qualifying homeowner acting as an owner-builder.
The licensing requirement itself comes from state law. Under NRS 624.700, it is unlawful to act as a contractor or bid on a job in Nevada without an active license unless an exemption applies. The Nevada State Contractors Board states that anyone who contracts for or bids on a construction project valued at $500 or more, counting labor and materials, must be licensed. Small repair and maintenance jobs under $1,000 can be exempt, but not when a building permit is required, when the work is plumbing, electrical, refrigeration, heating, or air conditioning, or when it is part of a larger project of $500 or more.
In the City of Las Vegas, only a Nevada licensed contractor may obtain a building permit for commercial construction. Before you hire anyone, verify the license on the board’s website, and see our guide on how to choose a general contractor in Las Vegas for what else to check.
What Are the Owner-Builder Rules in Nevada?
Nevada lets a homeowner act as their own contractor in limited cases. Under NRS 624.031, the licensing law does not apply to an owner who is building or improving a residential structure on their own property for their own occupancy and not for sale or lease. The owner must apply to the Contractors Board for the exemption, using its Owner-Builder Affidavit of Exemption, and submit it to the building department with the permit application.
The exemption comes with real responsibilities. As an owner-builder, you:
- Must directly supervise the construction yourself.
- May not hire an unlicensed person to act as your contractor, agent, or construction manager.
- Must use subcontractors who are properly licensed by the Nevada State Contractors Board.
- Must employ anyone working on the project who is not a licensed contractor, which brings employer duties like payroll withholding, industrial insurance, and unemployment contributions.
- Should not sell or lease the home soon after. Selling or leasing, or offering to, within 1 year after completion creates a presumption that the work was done for sale or lease, which violates the exemption.
Clark County adds its own conditions. The home must be a single-family dwelling used exclusively by the homeowner as a residence, the applicant must be the actual owner, and the owner signs an Owner/Builder Statement under NRS 278.573 acknowledging responsibility for supervising the work and following all codes and zoning rules.
What Are the Steps in the Permit Process?
Details vary by jurisdiction, but a typical remodel permit follows the same basic path:
- Scope the project and confirm which building department covers the address.
- Prepare plans when required. Simple like-for-like replacements often need no plans, while additions, structural changes, and layout changes usually do.
- Submit the application online. Clark County, the City of Las Vegas, Henderson, and North Las Vegas all use online portals for permits.
- Plan review, where the building department checks the plans against the adopted codes and requests corrections if needed.
- Permit issuance and fee payment, after which work can begin.
- Inspections during construction. In Clark County these include footing and foundation, slab and under-floor, framing after rough electrical, plumbing, and mechanical approvals, and a final inspection.
- Final approval, which closes out the permit.
Permits do not last forever. In Clark County, a permit becomes invalid if work does not start within 180 days of issuance, or if work stops for 180 days after it starts. North Las Vegas notes that some inspections may be done by video, with the inspector confirming the method ahead of time.
What Happens If You Remodel Without a Permit?
Skipping the permit can cost more than getting one. In unincorporated Clark County, as of October 2026:
- Work started without a required permit triggers a special investigation before a permit can be issued, and the work has to meet the code requirements for new construction unless the building official approves otherwise.
- A work-without-permit fee equal to the permit fees is added, up to $4,000 for residential construction, plus an investigation fee.
- The building official can issue a notice of violation or a stop work order when work is not in compliance.
Unpermitted work can also surface when you sell. Nevada’s Seller’s Real Property Disclosure Form asks sellers whether any construction, modification, alterations, or repairs were made without required state, city, or county building permits. It is also worth asking your insurance carrier how unpermitted work could affect coverage or a claim on your home.
If you already have unpermitted work, there are paths to fix it. Clark County allows the building official to reduce some fees for voluntary disclosure, and the City of Las Vegas runs a year-round amnesty program that lets homeowners self-disclose non-permitted work without penalties on the required plan review and permit fees.
