Selling a Las Vegas House With Unpermitted Work

Half the calls I take about permits start the same way. Somebody bought a 1958 bungalow off Maryland Parkway in 89104, the garage was already a bedroom when they got the keys, and now a buyer's agent is asking for the permit. Or it's a 1990s house in 89110 near Nellis Boulevard where a previous owner framed in the patio and called it a Florida room. Or a Henderson seller in 89015 off Boulder Highway added a casita for their mother and never called anyone.

None of that stops a sale. What stops sales is finding out about it three days before closing.

As of September 2026, in Las Vegas, Nevada, unpermitted work is one of the most common condition issues on resale homes built before 2000, and it is one of the easiest to handle when you deal with it up front. Here's exactly how it works in Clark County, what you legally owe a buyer, and what each of your three options actually costs you.

What counts as unpermitted work on a Las Vegas house?

Unpermitted work is any structural, electrical, plumbing, or mechanical change that required a building permit and never got one, or got one that was never finaled with a passing inspection. That second half surprises people. A permit that was pulled, worked under, and then abandoned before final inspection reads as open or expired in the county's system, and to a lender's underwriter it looks the same as no permit at all.

The versions I see most often across the Las Vegas Valley:

• Garage conversions. The single most common one, especially in 89104 Huntridge, 89102 Charleston Heights, and the older tracts in 89030 in North Las Vegas. A two-car garage becomes a bedroom, a studio, or a rental unit with no permit and no egress window.
• Patio enclosures and room additions. An Alumawood patio cover gets walls and a window unit, then a mini-split, then carpet. Very common in 89110 and 89121 on the east side.
• Backyard casitas and ADUs. Detached rooms with power run from the main panel, common in Spring Valley 89147 and the older parts of Paradise 89169.
• Added bathrooms. New plumbing tied into existing lines, usually in a converted garage or a basement-style bonus room.
• Electrical work. Subpanels for an RV pad, a spa circuit, or a detached shop. This one worries underwriters and insurers more than square footage does.
• Pool barriers and block wall height. Clark County has specific pool enclosure requirements, and a wall raised for privacy without a permit can trip a code check.

Routine maintenance is not unpermitted work. Paint, flooring, cabinets, a like-for-like water heater swap, and most landscaping do not require permits. If you replaced a roof, moved a wall, added square footage, added or relocated plumbing or electrical, or changed the HVAC system type, that is the category we're talking about.

Do I have to disclose unpermitted work when I sell in Nevada?

Yes, if you know about it. Under NRS 113.130, a seller of residential property in Nevada must complete and serve the Seller's Real Property Disclosure form on the buyer at least 10 days before the property is conveyed. NRS 113.100 defines a defect as a condition that materially affects the value or use of the property in an adverse manner. An addition the county has no record of fits that definition, because it affects both what the house is worth and how a buyer can legally use it.

The form itself is Form 547 from the Nevada Real Estate Division. You fill it out from your own knowledge. You are not required to hire an inspector, order a permit history, or go find defects you don't know about. You are required to tell the truth about what you do know.

The penalty for getting this wrong is not small. Under NRS 113.150, if a seller conveys the property without proper disclosure and there's a defect the seller knew about, the buyer can recover treble the amount necessary to repair or replace the defective part of the property, plus court costs and reasonable attorney's fees. A claim can be brought within one year of discovery or two years after conveyance, whichever is later. Nevada also does not let a buyer waive the disclosure requirement, and a seller cannot make waiver a condition of the sale.

Read that sequence again, because it's the whole argument for disclosing. A garage conversion you disclose is a negotiating item. The same garage conversion, undisclosed, is a three-times-repair-cost claim with attorney's fees attached, hanging over you for up to two years after you've already spent the money.

The people telling Las Vegas sellers that unpermitted work is "no big deal, we'll just close quietly" are usually the ones with no license to lose. I carry a fiduciary duty to you under NRS Chapter 645. That duty includes telling you the thing that costs me the easier transaction.

How do I find out what's actually permitted on my property?

Before you decide anything, get the record. And the first thing to establish is which government you're dealing with, because the Las Vegas Valley is not one jurisdiction.

A Summerlin address in 89135 and a Las Vegas Strip-adjacent address in 89169 can both say "Las Vegas, NV" in the mailing address while sitting in completely different permitting authorities. Unincorporated Clark County covers Paradise, Enterprise, Spring Valley, and Summerlin South. The City of Las Vegas covers the northwest and the older core. Henderson, North Las Vegas, Boulder City, and Mesquite each run their own building departments. Pahrump sits in Nye County entirely.

Pull the record from the right one:

• Unincorporated Clark County: the Clark County Building and Fire Prevention department maintains permit records and takes public records requests for building permit history. Clark County also runs a Citizen Access portal for permit lookups by address or parcel.
• City of Las Vegas: permit history runs through the City of Las Vegas permits and licenses office.
• Henderson and North Las Vegas: each city's building and safety division holds its own records. A Henderson house in 89052 near Horizon Ridge Parkway is a Henderson record, not a Clark County one.

Then cross-check the Clark County Assessor. The Assessor lists the square footage of record for your parcel. If the Assessor says 1,450 square feet and your house measures 1,780, you have roughly 330 square feet nobody knows about. That gap is the fastest unofficial permit check there is, and you can do it in ten minutes from your phone.

How much does unpermitted work actually cost a Las Vegas seller?

The honest answer is that it costs less than most sellers fear and more than most cash buyers admit. Here is the mechanism, not a guess at a number.

An appraiser measures gross living area from the exterior and generally counts only finished space that is legally habitable and consistent with what the market accepts. Unpermitted square footage frequently gets excluded from that gross living area or gets valued well below the rate applied to permitted space. So a converted garage that added 380 square feet of living space may add close to nothing to the appraised value, while also removing covered parking, which does have value in a market where July surface temperatures routinely sit above 105 degrees.

Then the loan. Conventional and government-backed financing runs through an underwriter who reads the appraiser's comments. If the appraiser flags the addition as not permitted, the underwriter can require the appraisal be completed as if the space doesn't exist, require permits before funding, or decline the file. Any one of those outcomes kills a retail buyer's timeline, which is why unpermitted work so often surfaces at day 18 of a 30-day escrow and blows the whole thing up.

And insurance. Carriers can deny a claim on a portion of a structure that was never permitted or inspected. That's a real risk a buyer inherits, and a well-advised buyer will price it.

What all of that means practically: unpermitted work usually costs you buyer pool and financing options more than it costs you raw dollars per square foot. That distinction matters when you choose your path.

What is Yvonne's Permit Reality Check?

This is the five-step sequence I run with every Las Vegas seller who has unpermitted work, before anybody decides whether to permit, price, or sell as-is.

1. Identify the jurisdiction and pull the permit record. Confirm whether the parcel is in unincorporated Clark County, the City of Las Vegas, Henderson, North Las Vegas, Boulder City, Mesquite, or Nye County, then request the permit history from that authority so you're working from the record instead of memory.
2. Measure the house and compare it to the Clark County Assessor's square footage of record. The difference between measured and recorded square footage tells you the scale of the problem in one number before you spend a dollar.
3. Classify the work by risk, not by size. Cosmetic and non-structural items sit at the bottom, added square footage sits in the middle, and anything involving electrical, gas, or structural load sits at the top, because that's the order underwriters and insurers care about.
4. Get one written estimate for bringing it to permit. Call the building department for the correction path and get a licensed contractor's bid, so the "just permit it" option becomes a real number and a real timeline instead of an assumption.
5. Put the number against your net in all three scenarios. Compare permit-then-list, list-and-price-it-in, and as-is cash side by side on net proceeds and closing date, and pick the one that actually wins. Disclose the work in every one of the three.

Step five is the one people skip, and it's the only step that answers the question they actually asked.

Permit it, price it in, or sell as-is for cash?

All three are legitimate. They fit different sellers.

Factor	Permit it first	List and price it in	As-is cash sale
Typical timeline	Weeks to months, depending on plan review, corrections, and re-inspection	Normal escrow, if the buyer's lender accepts the condition	Shortest, because no lender is reading the appraiser's comments
Out of pocket before closing	Highest. Permit fees, drawings, contractor work, possible demolition of non-conforming framing	Low, but you absorb it in the price instead	None
Who carries the risk	You, until final inspection passes	Shared, and it can resurface at appraisal	The buyer, in writing, at contract
Effect on buyer pool	Widest. Opens full financing	Narrower. Some lenders and some buyers walk	Narrowest, but it only takes one
Disclosure still required?	Yes. Disclose the history and the correction	Yes	Yes. As-is does not cancel NRS 113.130
Best when	The work is sound, the gap is large, and you have time and cash	The work is minor and the house is otherwise strong	You need certainty, speed, or the correction cost exceeds the gain

Worth saying plainly: an as-is sale is not a loophole. It shifts repair responsibility, not disclosure responsibility. If you want the mechanics of that, I broke it down in what an as-is addendum actually does in a Nevada contract.

What mistakes do Las Vegas sellers make with unpermitted work?

1. Staying deliberately ignorant. Sellers avoid pulling the permit history so they can honestly write "unknown" on the disclosure. It doesn't work the way they hope, and it guarantees the issue surfaces mid-escrow instead of before listing, when you still had options.
2. Advertising the square footage they measured instead of the square footage of record. Marketing a 1,450-square-foot house of record as 1,780 square feet is how a disclosure problem becomes a misrepresentation problem.
3. Starting demolition to "undo" it. Tearing out a converted garage the week before listing usually creates a half-finished space that appraises worse than the conversion did, and you still disclose the history.
4. Pulling a permit without asking what the correction path requires. Applying for an after-the-fact permit can trigger inspection of work that is now buried behind drywall. Ask the building department what the process opens up before you file anything.
5. Taking a wholesaler's word that permits "don't matter to cash buyers." They matter to the resale buyer behind that cash buyer, which is exactly why the offer is priced the way it is. Ask what the number would be without the permit issue.
6. Assuming the neighbor's answer applies. A house in 89149 in the City of Las Vegas and a house in 89141 in unincorporated Clark County follow different departments and different correction processes.
7. Waiting for the appraisal to raise it. By then you've lost 20 days, the buyer has lost confidence, and your listing goes back on market with days on market already stacked against it.

What does the Las Vegas market look like right now?

According to Las Vegas Realtors, the median price of existing single-family homes sold in Southern Nevada in August 2026 was $475,000, down about 1% from August 2025. Condos and townhomes had a median of $299,900, up 0.6% year over year. A total of 2,252 existing homes, condos and townhomes sold during the month. Inventory stood at roughly 7,590 single-family homes listed without offers, up 5.3% from a year earlier, and 2,714 condos and townhomes, up 6%, which works out to just over four and a half months of supply.

Reporting on the same Las Vegas Realtors release put the median time on market at 58 days, a 3.6% increase from a year earlier, with 24.2% of listings taking a price cut.

That is the context that should drive your decision. In a four-and-a-half-month market with a quarter of listings cutting price, a condition issue that narrows your buyer pool costs more than it did two years ago. Buyers have choices. A clean file wins, and a file with a surprise in it gets re-traded.

Frequently asked questions about selling a Las Vegas house with unpermitted work

Can I sell a house in Las Vegas with an unpermitted addition?

Yes. Nevada has no law requiring permits to be in place before a residential sale. You must disclose the unpermitted work you know about on the Seller's Real Property Disclosure form under NRS 113.130. Buyers using conventional financing may face lender conditions, which is why many unpermitted-addition sales in Las Vegas close as cash transactions.

Do I have to tell a buyer about a garage conversion I didn't do myself?

If you know about it, yes. NRS 113.130 requires disclosure of defects known to the seller, regardless of who performed the work or when. A conversion that existed when you bought the house is still a known condition. Write what you know, note what you don't, and never state that work was permitted unless you have the record.

Will the county fine me for unpermitted work when I sell in Clark County?

A sale by itself does not trigger a county inspection in Clark County. Code enforcement generally responds to complaints or to permit applications, not to real estate transactions. Applying for an after-the-fact permit is the step that brings the work under official review, which is why sellers should ask the building department about the correction path first.

Does unpermitted square footage count in a Las Vegas appraisal?

Often it does not. Appraisers typically exclude space that is not legally habitable from gross living area, or value it well below permitted space. A 380-square-foot garage conversion may add little appraised value while removing covered parking. That gap between what you built and what appraises is the real cost of unpermitted work in Las Vegas.

Can I get a permit after the fact in Las Vegas or Henderson?

Usually yes, though the process differs by jurisdiction and by what was built. Expect plan submittal, inspection of the existing work, and corrections to meet current code. Because inspectors may require opening finished walls to verify framing, wiring, or plumbing, get the correction path and a contractor bid in writing before you apply.

Does selling as-is mean I don't have to disclose unpermitted work?

No. An as-is sale shifts responsibility for repairs, not the duty to disclose. NRS 113.130 still applies, and NRS 113.150 still exposes a seller who knowingly conceals a defect to treble damages and attorney's fees. As-is protects you from being asked to fix it. Disclosure protects you from being sued over it.

How do I find out if my Las Vegas house has open or expired permits?

Request the permit history from the authority that governs your parcel. Unincorporated Clark County records come through Clark County Building and Fire Prevention, City of Las Vegas records through the city's permit office, and Henderson and North Las Vegas through their own building departments. Ask specifically for permits that were issued but never finaled.

Will a cash buyer in Las Vegas pay less for a house with unpermitted work?

Usually somewhat less, because the condition narrows the buyer pool on their eventual resale. How much less varies widely with the type of work. Ask any cash buyer what the offer would be without the permit issue. A licensed agent has to show you that math. An unlicensed wholesaler does not.
