Nevada's New Casita Law and Your Las Vegas Home Sale
Nevada AB 396 changed casita rules on July 1, 2026. What it means for permits, appraisals, and cash offers when you sell in Clark County.
Quick answer: Nevada Assembly Bill 396 took effect July 1, 2026 and forced Clark County and the cities of Las Vegas, Henderson, and North Las Vegas to allow accessory dwelling units on residential lots. It changes what you can build going forward. It does not automatically legalize a casita already standing in your backyard, and it does not let you sell that casita separately from the house.
Casitas are everywhere in Southern Nevada. Some were built by the production builder with a permit and a separate entrance off the courtyard. Some were a converted garage a previous owner finished on a weekend. As of September 2026, in Las Vegas, Nevada, sellers are asking a new question about both kinds, because the rules changed this summer and the change got a lot of local coverage. The short version is that the new law is about future construction, and what matters at your closing table is still the permit history on your specific parcel.
What counts as an accessory dwelling unit in Nevada?
Assembly Bill 396 of the 2025 Nevada Legislature defines an accessory dwelling unit as "an independent living space that is built on the same lot as the primary residence on a residential property, regardless of whether the independent living space is attached, detached or built within the primary residence."
Read that carefully, because two words do the work. Independent means it functions on its own, which in practice means its own kitchen, bathroom, and sleeping area. Same lot means it shares your parcel number, your deed, and your tax bill.
A guest bedroom with an ensuite is not an ADU. A detached casita with a kitchenette, a three-quarter bath, and its own door to the side yard is. A garage conversion with a stove and a shower is one too, whether or not anybody pulled a permit for it.
What actually changed on July 1, 2026?
AB 396 requires larger local governments to adopt an ordinance authorizing ADUs on residential property. The statute reaches counties with a population of 100,000 or more and cities with a population of 60,000 or more. In Southern Nevada that is Clark County plus Las Vegas, Henderson, and North Las Vegas.
The law also sets floors those ordinances cannot go below. A local ordinance may not prohibit a separate kitchen in the unit, may not require more than one additional parking space where existing or street parking meets the need, may not impose setbacks stricter than those applied to the primary residence, and may not prohibit renting the unit as housing. It may prohibit using the unit as transient lodging, which is the short-term rental carve-out. And no ordinance may authorize more than two accessory dwelling units on a single residential property.
The Nevada Real Estate Division's 2025 legislative summary notes the consequence of missing the deadline: a covered jurisdiction that failed to adopt a compliant ordinance by July 1, 2026 would see ADUs allowed without restriction on any residentially zoned parcel. Local reporting from Fox5 Las Vegas in June 2026 indicated Henderson and Clark County had already made conforming code changes, North Las Vegas considered its existing code compliant, and the City of Las Vegas was moving a clarifying ordinance that keeps its limit at one ADU per property.
Worth knowing if you own outside the metro core: Boulder City, Mesquite, and Nye County all fall below the population thresholds in the statute, so the AB 396 mandate does not reach them. If your property is in Pahrump or Mesquite, your local code still governs on its own terms.
Does the new law make my existing unpermitted casita legal?
No, and this is where sellers get into trouble. AB 396 tells local governments what their zoning ordinances have to allow. It is not an amnesty program for work that was already built without a permit.
Whether the structure in your backyard can be permitted now is a determination your local building department makes, parcel by parcel, against the code in force. A unit that was built to no standard at all may need to be opened up for inspection, brought up to code, or removed. A unit that was built well but without paperwork may be a cleaner retroactive permit. Nobody can tell you which one you have from a photo.
Your disclosure obligations are also unchanged. What you know about the permit status of that structure still has to go on the Nevada seller disclosure, and a friendlier zoning code does not erase that. The mechanics of that, including how to pull your parcel's permit history, are covered in detail in our guide to selling a Las Vegas house with unpermitted work.
How does a casita change the appraisal and the buyer's loan?
This is the part that decides your net, and it runs on lender rules, not on city zoning.
The Fannie Mae Selling Guide, section B2-3-04, effective October 8, 2025, defines an ADU as an additional living area independent of the primary dwelling with its own living, sleeping, cooking, and bathroom facilities on the same parcel. Properties with an ADU are eligible, provided the unit stays subordinate in size to the main house and keeps its separate ingress and egress, kitchen, sleeping area, and bath.
On zoning, the guide draws the line most sellers never hear about. An ADU "should always be considered legal if it is allowed under the current zoning code for the subject property." Older units that predate the current code may qualify as legal nonconforming. Where the unit is not permitted under zoning at all, the property can still be eligible, but only if the lender confirms the unit's existence will not jeopardize a future property insurance claim and the appraisal requirements are met. The guide puts the burden on the appraiser to determine compliance as part of the Highest and Best Use analysis.
Translate that into a Clark County closing and you get three different outcomes from the same square footage, depending entirely on paperwork. Financed buyers live or die on this. A cash buyer does not need the loan to clear, which is why a casita with a cloudy permit history often draws a cash offer that beats a financed offer that never closes. That tradeoff is the same one at work in whether your Las Vegas house passes an FHA appraisal.
What a casita's permit status does to your sale
| Status of the unit | Financed buyer | Appraisal treatment | Cash buyer |
|---|---|---|---|
| Permitted and allowed under current zoning | Cleanest path | Treated as legal; contributory value supportable | Pays for it, competes with the open market |
| Predates current code, legal nonconforming | Usually workable, needs documentation | Appraiser analyzes conformity and highest and best use | Rarely an obstacle |
| Not permitted under zoning | Lender must clear the insurance question first | Square footage may not count toward value | Prices the risk in, but closes |
| Built with no permit and unknown construction quality | Frequent deal killer | Often excluded entirely from the value | Most likely remaining buyer pool |
Can I sell the casita separately from the house?
No. AB 396 contains no provision authorizing separate conveyance of an accessory dwelling unit, and the statute's own definition puts the unit on the same lot as the primary residence. One parcel, one legal description, one deed. You sell them together or not at all.
Sellers ask this more often than you would expect, usually one of two ways. Some want to keep the casita for an aging parent and sell the main house, which is not possible without a lot split that Clark County or the city would have to approve as a separate land-use action. Others assume a rented casita makes the property a duplex they can market to investors as two doors. It is one door with an accessory unit, and appraisers and lenders treat it that way.
Yvonne's Casita Sale Check
- Pull the permit record on your parcel before you talk to anyone about price. The permit history, not the zoning code, is what a lender and an appraiser will react to, and you want to know what it says before a buyer's inspector tells you.
- Confirm which jurisdiction you are actually in. An address with a Las Vegas mailing label is frequently in unincorporated Clark County, and the two have adopted different ADU rules, so the wrong assumption sends you to the wrong counter.
- Decide whether to permit it, price it in, or sell as-is. Retroactive permitting can add value on a financed sale, but it takes time and can uncover work that has to be redone; pricing it in or selling as-is trades that upside for certainty.
- Put the unit's status on the disclosure in writing, whichever path you pick. Nothing kills a Southern Nevada closing faster than a casita the buyer learns about from the appraiser instead of from you.
- Compare a cash number against a listed number with the casita valued both ways. If the unit counts toward value on the MLS path and gets excluded on appraisal, the listed number you were promised was never real.
What mistakes do Las Vegas sellers make with a casita?
- Assuming AB 396 retroactively legalized an existing unpermitted unit. It governs what ordinances must allow going forward.
- Advertising the casita's rent as income without confirming the unit is a legal rental under the local ordinance and any recorded restrictions on the property.
- Counting the casita's square footage in the asking price before anyone has confirmed it is included in the county's records.
- Treating a Las Vegas mailing address as proof of City of Las Vegas jurisdiction when the parcel sits in unincorporated Clark County.
- Marketing the property as a duplex or as two units because there are two kitchens.
- Leaving a tenant in the casita through escrow without deciding how that tenancy is handled at closing. If someone is living in yours, read selling a rental property with tenants in Las Vegas first.
- Assuming an HOA cannot say anything about the structure. Community restrictions are a separate layer from city or county zoning, and in Summerlin and Henderson they often have their own architectural review. Your HOA resale package is where that history shows up.
Key takeaways
- Nevada AB 396 took effect July 1, 2026 and requires Clark County, Las Vegas, Henderson, and North Las Vegas to allow accessory dwelling units on residential property, with statutory floors on kitchens, parking, setbacks, and rental use.
- No ordinance under AB 396 may authorize more than two accessory dwelling units on one residential property, and a jurisdiction may set a lower limit.
- The law does not legalize an existing unpermitted casita. That remains a parcel-by-parcel determination by the local building department.
- Fannie Mae's Selling Guide treats an ADU as legal when current zoning allows it; where zoning does not, the lender must confirm the unit will not jeopardize a future property insurance claim.
- An accessory dwelling unit sits on the same lot as the house and cannot be conveyed separately.
Yvonne's takeaway: the casita question is never really about the casita. It is about which buyer pool can still close on your house once the appraiser writes down what is actually back there, and that is a question worth answering before you pick a price, not after an offer falls apart.
Frequently asked questions about selling a Las Vegas home with a casita
Does AB 396 mean I can build a casita on any Las Vegas lot now?
Not automatically. The law requires covered jurisdictions to adopt an ordinance authorizing accessory dwelling units and sets limits on how restrictive that ordinance can be. Your specific lot still has to satisfy the adopted local ordinance on size, setbacks, and permitting. Check with the jurisdiction your parcel actually sits in.
How many casitas can one Las Vegas property have?
AB 396 bars any covered local ordinance from authorizing more than two accessory dwelling units on a single residential property. That is a ceiling, not an entitlement. A city or county may allow fewer, and local reporting in June 2026 indicated the City of Las Vegas was keeping its limit at one per property.
Will an appraiser count my casita's square footage?
It depends on permit and zoning status. Fannie Mae's Selling Guide puts the determination on the appraiser as part of the Highest and Best Use analysis. A permitted unit allowed under current zoning is treated as legal. An unpermitted unit is frequently excluded from the value even though the space is physically there.
Can I sell my casita to my adult child and keep the house?
No. An accessory dwelling unit sits on the same lot as the primary residence and shares one parcel and one deed. Separating it would require a land division approved by your city or county as its own land-use action, which is a very different process from a home sale.
Do I have to disclose that my casita was never permitted?
Nevada's seller real property disclosure obligations apply to what you know about the property's condition, and permit status of an existing structure falls squarely in that territory. A more permissive zoning code does not change what you are required to tell a buyer. Ask your broker or a Nevada attorney about your specific situation.
Does a cash buyer care whether the casita is permitted?
Usually less than a financed buyer does, because there is no lender applying the Selling Guide rules and no appraisal condition to clear. The permit status still affects the number. A cash buyer prices the cost and risk of resolving it, which is why two offers on the same casita can be thousands apart.
Can my HOA stop me from renting the casita?
Local zoning and community restrictions are separate layers. AB 396 limits what a city or county ordinance may prohibit, and the 2025 session also amended the common-interest community statutes. What your specific association can enforce depends on its recorded governing documents, so have a Nevada attorney review them before you rely on rental income.
