There’s no single Nevada statute that requires carbon monoxide detectors in every rental and hotel. The requirement depends on the type of property and where it is: Clark County and Las Vegas short-term rentals must have CO alarms by law, while apartments and hotels are mainly governed by the fire and building codes each local government adopts.
If you’re checking because someone you love was hurt or killed, the answer can matter a great deal. Here’s where the rules come from, how they differ by property, and when a carbon monoxide poisoning lawyer in Las Vegas should look at what the property was required to have.
Nevada Carbon Monoxide Detector Rules by Property Type
Here’s a general overview for the Las Vegas area. Codes change and local amendments vary, so treat this as a starting point, not a final answer for any specific building.
| Property type | Main source of the rule | What it generally requires |
|---|---|---|
| Short-term rental in unincorporated Clark County | NRS 244.35356 and the county’s rental ordinance | A CO alarm, a smoke alarm, and a fire extinguisher, with mechanical systems kept hazard-free |
| Short-term rental in the City of Las Vegas | Las Vegas Municipal Code | CO alarms installed under the adopted codes, plus smoke alarms in sleeping rooms |
| Apartments and long-term rentals | Locally adopted fire and building codes | CO alarms where the code calls for them, usually tied to fuel-burning appliances or attached garages |
| Hotels and resorts | Locally adopted fire and building codes | CO detection where the code calls for it, usually tied to fuel-burning equipment |
| Smoke alarms (for comparison) | NRS 477.140, plus local codes | A smoke detector in every unit of apartment buildings with 3+ units and every sleeping room of hotels and motels with 6+ rooms |
Smoke alarms have a clear statewide rule. Carbon monoxide alarms, outside of short-term rentals, mostly don’t. That’s why the local fire code matters so much.
Where Nevada’s Carbon Monoxide Rules Actually Come From
Most CO alarm requirements in Southern Nevada come from the International Fire Code and International Building Code, which local governments adopt and amend. Clark County, Las Vegas, Henderson, and North Las Vegas coordinate many of their amendments regionally. Clark County began enforcing the 2024 International Fire Code in January 2026.
These codes generally call for carbon monoxide detection in apartments, hotels, and other places people sleep when the building has fuel-burning appliances, fireplaces, or an attached garage. The details, including which rooms, which buildings, and whether older buildings must be upgraded, depend on the code edition and the local amendments.
The Rules Are Still Moving
In 2026, Southern Nevada fire officials asked for public input on further changes to the carbon monoxide section of the fire code. That’s one reason a lawyer checks which version of the code applied when the property was built or renovated, when it was last inspected, and on the date of the death.
What Nevada Landlord and Hotel Law Does and Doesn’t Say
Nevada’s landlord-tenant law, NRS 118A.290, doesn’t mention carbon monoxide detectors by name. It does say a rental isn’t habitable if it violates housing or health codes that affect safety, or if the heating facilities and the ventilation and appliances the landlord supplies aren’t kept in good repair.
That matters because CO deaths almost always trace back to heating equipment. A landlord who ignored a faulty furnace or a water heater with a disconnected vent may have broken that duty, whether or not a separate detector rule applied. Our post on who is liable for an injury at an apartment complex in Las Vegas covers landlord duties more broadly.
Hotels have their own state rules. NRS 447.145 requires hotel heating and ventilating systems to be built and run in a way that keeps the risk of gas poisoning to a minimum. If a guest was hurt but survived, our casino and hotel injury page covers those claims.
Older Buildings and “Grandfathered” Properties
Many Las Vegas apartment complexes and off-Strip motels were built decades before modern CO rules, and owners often argue the newer requirements don’t apply to them. Some code provisions apply only to new construction or major renovations, while others reach existing buildings. Even a grandfathered building still has to keep its heating equipment safe under general premises liability rules. The answer depends on the code edition, the building’s permit history, and how the building is used.
Missing Carbon Monoxide Detector, Fatal Result: What It Means for a Claim
When the law or the code required a CO alarm and the property didn’t have one, or had one that didn’t work, that failure can be powerful evidence of negligence in a Nevada wrongful death case. A safety rule written to prevent carbon monoxide deaths is exactly the kind of rule that can help prove a death was preventable. Our premises wrongful death page explains how families use code violations to hold property owners accountable.

Frequently Asked Questions
Are landlords required to provide carbon monoxide detectors in Nevada?
It depends on the property. For permitted short-term rentals in Clark County and the City of Las Vegas, yes: state and local rental rules require a CO alarm. For apartments and long-term rentals, the requirement usually comes from the locally adopted fire and building codes, which tie CO detection to fuel-burning appliances, fireplaces, or attached garages. Nevada’s landlord-tenant statute doesn’t name CO detectors, but it does require landlords to keep heating equipment in good working order and to follow safety codes. If you’re unsure about a specific unit, the local fire or building department can tell you which code applies.
Do Las Vegas hotels have carbon monoxide detectors in rooms?
Not every hotel room has its own CO detector. Under the fire codes adopted in Southern Nevada, carbon monoxide detection in hotels is generally tied to fuel-burning equipment and where it sits in the building. Depending on the layout, some buildings may use detection in specific areas rather than in every room. What a particular hotel was required to have depends on its age, its renovations, and the code edition in force. If a guest was harmed, a lawyer can pull inspection and permit records to find out what the hotel owed its guests and whether it delivered.
Where should a carbon monoxide detector be placed?
Building and fire codes generally call for CO alarms outside each sleeping area, and many also call for one on each level of a home. In larger buildings, codes may require detection in or near rooms with fuel-burning appliances. Manufacturers also give placement instructions, such as distance from appliances and height on the wall. In a rental, placement should follow the code that applies to that building. A detector in the wrong spot, like a far hallway or behind furniture, may not wake sleeping guests in time, and placement can become a key question when an alarm existed but didn’t sound early enough.
Who replaces carbon monoxide detector batteries in a rental?
Leases often ask tenants to test alarms and replace batteries, and Nevada doesn’t have a single statewide rule assigning that task for CO detectors. Even so, the owner usually stays responsible for installing the required alarms and making sure they work at move-in and after repairs. In a short-term rental, the permit holder is responsible for keeping the alarm in place between guests, since travelers can’t be expected to test it. Many newer alarms use sealed 10-year batteries, which reduces the problem. If an alarm failed, who was supposed to maintain it is a fact question a lawyer can sort out.
Find Out What the Property Was Required to Have
The code question is technical, but you don’t have to answer it alone. Howard Injury Law can pull permits, inspection reports, and code history to show what the property owed your family and whether it delivered. Glen Howard’s years defending insurance companies mean he knows the “the code didn’t apply to us” argument well.
