Smart Smoke & Carbon Monoxide Detectors for Renters

Smart smoke and carbon monoxide alarms have become a necessity for a safe home, and renters must not ignore the need. As of 2025, renters in the U.S. should generally expect smoke alarms in key locations. This includes HUD-assisted home and CO alarms in units with fuel-burning appliances or garages. The regulations vary as per state law. That’s why it is wise to

1. As renters, you must know your local laws. You should also be aware of your state, city, or building fire codes, too.
2. Test your smoke and CO alarms regularly and report faults to your landlord.
3. Use sealed, long-life batteries and interconnected smoke alarms.
4. Ensure CO detectors are properly placed and functional.

Updated Guidance for Renters in the United States Regarding Smoke and Carbon Monoxide Alarm Regulations

There is no single federal standard for smoke and carbon monoxide alarm regulations. The requirements may vary by program and state. However, here are the key national-level and state-level highlights of the regulations. 

Federal Standards & HUD-Assisted Housing

This regulation is according to HUD-Assisted Housing (Section 8, Project-Based Vouchers). It was implemented on December 1, 2024. According to this regulation, rental units receiving HUD assistance are required to install hard-wired smoke alarms. These alarms must be equipped with a 10-year battery, and renters should also have carbon monoxide detectors in new locations.

NSPIRE Standards (Housing Quality/Inspection)

The National Standards for the Physical Inspection of Real Estate (NSPIRE) specifies that rental properties must have:

• At least one working smoke detector on each level.
• Smoke alarms should be inside each bedroom. These alarms should be within 21 feet of any bedroom door.
• CO detection standards per HOPWA NSPIRE guidelines.

Short-Term Rentals

A pending bill (House Bill 3918) would require smoke and CO detectors in short-term rentals. This includes Airbnb or VRBO, and makes it illegal to rent without them. This has not yet become law.

State-Level Variations

Each state has different laws on how it enforces smoke and CO detector requirements.

Smoke Alarms:

• Nearly all states require smoke detectors in residential properties.
• Most new constructions must have hard-wired, interconnected alarms
• Some states (like Iowa) mandate 10-year sealed battery smoke alarms in homes.
• California requires alarms in all bedrooms and hallways

Carbon Monoxide Alarms:

Many states require CO detectors, but the rules vary:

• In Illinois, these detectors are required within 15 feet of sleeping areas.
• In Oregon, landlords are prohibited from renting units with CO sources unless an approved CO alarm is installed.
• NCSL compilation offers a state-by-state breakdown. Most states have at least some requirement for CO detector installation in residential settings.

Safety Advice for Renters

Even if your state does not have any strong regulations, it is best to practice being proactive. follow

Smoke alarms	CO alarms
You generally must have one per level of your unit, inside each bedroom, and near bedrooms	Should be placed on every level of the home, near sleeping areas, and at head to knee height (not on the ceiling).
Hard-wired, interconnected alarms offer the best protection.	CO gas mixes with air and doesn’t rise like smoke. That’s why proper placement is essential
Battery-operated units are acceptable. But those with sealed 10-year batteries require less maintenance	There are no federal requirements for CO alarms in hotels or vacation rentals.  State laws are also inconsistent. That’s why carrying your own portable CO detector is often the safest choice when staying in unknown lodging

Government data shows that you are eight times more likely to die in a fire without a working smoke alarm. In 2023, there were over 26,000 dwelling fires in England. Hundreds of lives were lost in these incidents.

In the UK, CO poisoning causes around 40 deaths and 200 to 250 hospitalizations every year. Common sources of carbon monoxide leaks in homes include:

• Fireplaces and wood stoves
• Gas dryers and heaters
• Some furnaces
• Vehicles running in enclosed spaces

What to Do if Your Home Doesn’t Meet the Regulations?

If you think that your home does not have the required smoke or carbon monoxide alarms, then:

• Install a CO alarm in every room with a fixed combustion appliance
• Install a CO alarm when any new fixed combustion appliance is fitted
• Fix or replace any faulty smoke or CO alarms as soon as they are told about the problem.
• Provide smoke alarms on every floor that has living space.

If you rent in a shared or House in Multiple Occupation (HMO), for example, shared flats, bedsits, or a house split into rooms, extra rules apply:

• Smoke alarms in every bedroom and shared hallways/landings.
• Heat alarms in kitchens.
• Alarms must be interlinked and mains powered.
• Landlords must maintain the system and carry out checks, usually every six months.

You should also be given fire safety information and know your escape routes. Regular fire drills may be carried out; take them seriously.

Although carbon monoxide is a silent killer. It is odorless, tasteless, and invisible; it does have symptoms like

• Headaches, dizziness, fatigue
• Nausea or confusion

• Yellow or orange flames instead of blue on a gas hob
• Soot marks around appliances
