Renting Out a Casita or ADU in Clark County

Drive through almost any established neighborhood in the Las Vegas Valley, from the ranch-style streets of Paradise to the newer masterplans in Summerlin and Mountains Edge, and you will spot them behind the main house. Casitas, guest houses, converted garages, and detached suites have been part of Southern Nevada living for decades. What has changed is the math. With rents at levels that make even a modest one-bedroom unit meaningful income, more Clark County homeowners are asking the same question. Can I legally rent out my casita, and what do I need to do first?

The honest answer is that this is one of the most rules-dependent moves a Las Vegas landlord can make, and the rules themselves are in the middle of a historic shift. Nevada passed a statewide ADU law in 2025, local governments have been updating their codes in response, and the difference between a casita, an accessory building, and a true accessory dwelling unit matters more than most owners realize. This guide walks through what we know, what is still settling, and how to protect yourself while you set the unit up.

Casita, Guest House, and ADU Are Not the Same Thing

People use these words interchangeably at backyard barbecues, but zoning code does not. In unincorporated Clark County, the code has long drawn a line based on two things, whether the structure is used for residential purposes and whether it contains a kitchen. A basic accessory building, think shed, workshop, pool house, or game room, is not supposed to be used for residential purposes at all. A casita, in the county’s usage, is a separate structure on a lot with a dwelling that is used residentially but does not have a kitchen. A full accessory dwelling unit goes a step further, functioning as an independent home with its own kitchen and bathroom.

That kitchen distinction is the hinge the whole question turns on. A structure with a bed and a bathroom but no kitchen has historically been treated as an extension of the main home, somewhere your in-laws or adult kids stay, not a separate rental dwelling. Once a kitchen enters the picture, you are effectively creating a second home on the parcel, and that has always drawn much closer scrutiny from planners. Clark County’s code enforcement office publishes guidance on single-family residential building violations that spells out these distinctions, and it is worth reading before you spend a dollar on improvements, because unpermitted conversions are one of the most common complaints the county investigates.

Nevada’s New ADU Law Changed the Landscape in 2026

In the 2025 legislative session, Nevada lawmakers passed Assembly Bill 396, often called the casita bill. The law added a new section to the state planning and zoning statutes, NRS 278.257, which took effect on July 1, 2026. In broad strokes, it requires larger local governments, counties with populations of 100,000 or more and cities of 60,000 or more, to adopt ordinances authorizing the development and use of accessory dwelling units on residential property. Clark County and the valley’s major cities all fall within those population thresholds.

What this means practically is that the era of blanket local hostility to backyard units is ending in Southern Nevada. It does not mean anything goes. Local governments still set standards on things like size, setbacks, design, and utilities, and jurisdictions that already had consistent ordinances in place before the deadline were allowed to keep them. The details of exactly what Clark County permits on your specific parcel, and under what conditions, are the kind of thing you confirm with the Comprehensive Planning department rather than assume from a news article. Rules were actively being updated through 2025 and 2026, and what was true for your neighbor two years ago may not be true for you today.

Your Jurisdiction Matters More Than Your Zip Code

Here is the part that surprises many valley homeowners. Las Vegas is not one jurisdiction. A home in Spring Valley, Paradise, Enterprise, Sunrise Manor, or Whitney sits in unincorporated Clark County and answers to county code. A home a mile away might be inside the City of Las Vegas, Henderson, or North Las Vegas, each with its own planning department, its own ordinance, and its own timeline for implementing the state ADU law. Summerlin splits between the City of Las Vegas and unincorporated county depending on the village. Green Valley and Anthem are Henderson. Aliante is North Las Vegas.

Before you do anything else, look up your parcel on the county assessor’s site and confirm which government actually regulates your lot. Every question that follows, whether you can add a kitchen, whether the unit can be rented separately, what parking you must provide, flows from that answer. Calling the wrong planning department wastes weeks, and relying on a rule from the wrong jurisdiction can cost far more.

Permits Are the Foundation of a Rentable Unit

Whatever your jurisdiction allows, one principle holds everywhere. A casita you rent to a tenant needs to be legal, permitted space. That means the original structure was built with permits, any conversion work, plumbing, electrical, mini-split HVAC, kitchen addition, was permitted and inspected, and the finished space complies with building code for habitable rooms. Ceiling height, egress windows, smoke and carbon monoxide detection, and proper ventilation are not bureaucratic trivia. They are the difference between an asset and a liability.

Unpermitted rentals carry a specific kind of risk that owners underestimate. If a tenant dispute goes sideways, the tenant now has leverage, because a single call to code enforcement can shut the unit down. If there is a fire or an injury in an unpermitted space, your insurer has an argument to deny the claim. If you ever sell, the unpermitted square footage complicates the appraisal and the deal. Every one of those scenarios costs more than doing it right the first time. If you are new to all of this, our guide for a first-time landlord working with property management in Las Vegas walks through how professional oversight keeps these compliance pieces from slipping.

HOAs Can Still Say No

The state ADU law reshaped what local governments must allow, and it also touched on the role of homeowners associations, but as a practical matter your CC&Rs remain a real constraint in much of the valley. Southern Nevada is one of the most HOA-dense markets in America. Summerlin, Anthem, Inspirada, Southern Highlands, Providence, and dozens of other communities have architectural review committees, restrictions on detached structures, and in many cases explicit leasing rules that govern whether any portion of a property can be rented, to whom, and for how long.

Read your governing documents before you draw up plans, and get anything ambiguous answered by the management company in writing. Some associations restrict the number of rentals in the community, some require rental registration, and some prohibit renting less than the entire property, which is exactly what a casita rental is. We cover this terrain in more depth in our piece on HOA rental restrictions in Las Vegas, and it applies doubly to backyard units, which tend to be visible, discussed by neighbors, and easy to report.

Long-Term Tenant or Short-Term Guests

Many owners first imagine their casita as a nightly rental for visitors coming for a fight weekend or a residency at the Sphere. Slow down. Short-term rental rules in Southern Nevada are strict, license-limited, and enforced, and unincorporated Clark County in particular has taken a hard line, with a licensing program that is competitive to enter and rules that many casual hosts cannot meet. Before you buy furniture, read our breakdown of the Airbnb rules in Clark County and be realistic about whether your property can qualify at all.

A long-term casita rental, a tenant on a twelve-month lease, is the simpler, steadier play for most owners. It avoids the short-term licensing gauntlet, generates predictable income, and puts one stable person in your backyard instead of a rotating cast of strangers. It is also far easier to manage remotely, insure properly, and defend to an HOA. For most Clark County homeowners weighing the two, the long-term route wins on both risk and net return once you price in vacancies, cleaning, and compliance costs on the short-term side.

Pricing a Backyard Unit Honestly

A casita does not rent like a standard apartment, and pricing it like one is the most common mistake we see. On the plus side, tenants get a detached home with no shared walls, often with a private entrance and a slice of yard, in neighborhoods where small rentals barely exist. On the minus side, the tenant usually shares a driveway, sometimes shares laundry, and lives a few steps from the owner. The right comparison set is other casitas, guest houses, and small single-family homes in your area, not the one-bedroom units at the apartment complex on the arterial.

Utilities complicate pricing too. Most casitas are not separately metered for power and water, so you will likely fold utilities into the rent or set a flat monthly utility charge spelled out in the lease. Price that honestly, because a Las Vegas summer of running a mini-split all day is not a rounding error. Our guide on how to set a rent price in Las Vegas covers the comp-driven process we use, and it applies here with the adjustments above.

Licensing, Taxes, and the Paper Trail

Once your casita is a rental, you are a landlord in the eyes of every agency that cares about rentals. Depending on your jurisdiction, that can mean a business or rental license, and it certainly means reporting the income on your taxes, where you will also get to take the deductions that come with rental property. Requirements differ between unincorporated Clark County, the City of Las Vegas, Henderson, and North Las Vegas, so verify what applies to your address rather than borrowing a friend’s checklist. We walk through the county-side process in our guide to getting a rental license in Clark County.

Tell your insurance carrier the truth as well. A homeowner policy written for a single family in one dwelling does not automatically cover a paying tenant in a detached structure. You will likely need landlord coverage for the rental exposure, and you should require renters insurance from the tenant. None of this is expensive relative to the income, and all of it is cheap relative to an uncovered loss.

Write the Lease for the Realities of Shared Ground

A casita lease needs everything a normal Nevada lease needs, plus a layer that addresses the shared-property realities. Where does the tenant park, and where do guests park? Which yard areas are theirs, which are yours, and which are common? Who maintains the landscaping and the pool, and is the tenant allowed to use the pool at all? How is access handled, given that you may need to cross their space to reach equipment, and they may need to cross yours to reach the street? What are the quiet hours, and how do packages get delivered?

Spell all of it out before move-in, because the friction in owner-adjacent rentals almost never comes from rent. It comes from the hundred small ambiguities of sharing a parcel. A precise lease, a thorough move-in inspection with photos, and a professional tone from day one prevent most of it.

Should You Self-Manage a Tenant Twenty Feet Away

Living next to your tenant sounds convenient and often becomes the opposite. Every maintenance request arrives as a knock on your door. Every late payment becomes a personal confrontation instead of a process. Every boundary you fail to hold becomes the new normal. Owners who are naturally firm and organized can make it work. Many others discover that the proximity that made the casita easy to build makes it hard to manage.

A manager in the middle changes the dynamic entirely. The tenant calls the management office, not your doorbell. Rent is collected, documented, and enforced on a schedule. Maintenance is dispatched to licensed vendors, and the records you need at tax time or in a dispute exist without you building them. For a unit that shares your fence line, that professional buffer is often worth more than it costs.

Getting Your Casita Rented the Right Way

The opportunity is real. Southern Nevada needs small rental homes, the state has pushed the legal framework toward allowing them, and a permitted, well-run casita in a good neighborhood can produce durable income from ground you already own. The sequence matters, though. Confirm your jurisdiction, verify what your parcel allows with the planning department, permit the work, clear it with the HOA, insure it, license it where required, and put a lease on it that anticipates shared-ground friction.

If you would rather hand that sequence to people who do it every week, Investment Realty & Property Management has been guiding Las Vegas owners through exactly these decisions for years, from evaluating whether a casita makes sense to leasing and managing the finished unit.
