The fire safety count for your co-living house: alarms, extinguishers, drills

Issue #031 | Friday, November 6, 2026 | thecolivinginsider.com

Product Warning!

On October 29, the Consumer Product Safety Commission told people to stop using two low-cost combination smoke and carbon monoxide alarms sold on Amazon and eBay: model JZA-540COM (JuzhiAnn, Yfwsrecinoe, and JAEHSKA brands) and model YHW-542COM-R (GuardianSense and KLTseanife). The Consumer Product Safety Commission (CPSC) says both can fail to alarm when smoke or fire is present. It logged seven such reports on the first and two on the second.

Operators buy alarms in multipacks, and multipacks are where these were sold. CPSC's instruction is simple: stop using them, dispose of them, and buy only alarms that meet UL 217 for smoke and UL 2034 for carbon monoxide.

Walk your houses this weekend and read the back of every alarm. You're looking for three things: the brand and model, a UL 217 or UL 2034 marking, and the manufacture date. Replace anything 10 years old or older. If you can't read a label, treat that alarm as a failed alarm.

Co-living raises the stakes. In an ordinary rental, one household knows its own routines. Here, a new resident may not know where the second stairway is, and the person down the hall may have taken out their hearing aids. Your systems have to do what family habits do in a normal home.

Every number below depends on how your city classifies the house. The same five-bedroom can fall into different categories depending on who lives there and how you rent it.

California's current building code, for example, puts non-transient congregate residences with 16 or fewer occupants in Group R-3. Baltimore draws its R-3 line at 5 or fewer occupants. An owner-occupied lodging house with five or fewer guest rooms can often use the residential code, though California adds a sprinkler requirement to that route.

That matters for extinguishers in particular. The model International Fire Code requires them in Groups R-1, R-2, and R-4, but R-3 isn't on the list. Your city can add to the model code, and many do. Saint Paul, for instance, requires extinguishers in apartment houses with four or more units.

Call the fire marshal's office and ask three questions:

Issue #011 of The Co-Living Insider newsletter (https://shorturl.at/ekeGD) explained permits, and Issue #013 (https://shorturl.at/fjmaP) explained how houses get classified. Today’s issue covers what you need to install and do once you know which rules apply.”

That sentence is still good law. Check your local definition of "family" before you buy. This is not legal advice; verify with a local land-use attorney.

"Code minimum" below means the model codes before state and local changes. Your local rules control.

A worked example. Take a two-story house with five upstairs bedrooms, a basement, a gas furnace, and an attached garage.

Using eight First Alert combination alarms at $36.99 and three First Alert 2-A:10-B:C extinguishers at $49.99, that's about $446 before tax. That's the top of the range, since bedrooms can use smoke-only alarms.

Placement details that trip people up:

An alarm you can't prove you tested is just an opinion. Keep a one-page log for each house, with dates and initials. If there's ever a fire, a claim, or a code complaint, that log is your evidence.

Monthly: Test every alarm ( National Fire Protection Association - NFPA-based local guidance and CPSC both say monthly). Check each extinguisher's gauge, pin, hose, and body. Walk the exits for blocked hallways and stuck doors. Your property manager can do all of this during a regular house check.

Every turnover: Test the bedroom alarm, confirm the bedroom door opens from the inside without a key or code, reset the lock code, and walk the new resident through the escape routes.

Annually: Have a professional inspect and service all fuel-burning heating systems, including chimneys and vents. If your classification requires extinguishers, book the annual maintenance too. Clean dryer lint ducts while you're at it.

At year 10: Replace every alarm. Write the install date on the alarm itself. Check the manufacturer's life for CO alarms, because the sensors wear out too.

Fire prevention in co-living comes down to your house rules. Put these in the resident agreement and post them.

Cooking. Unattended cooking is the leading cause of kitchen fires. The rule is "if the stove is on, someone has to be in the kitchen." Shared kitchens need it most, because everyone assumes someone else is watching the pot.

Space heaters. This is the rule to enforce today. CPSC says keep them 3 feet from anything combustible, plug directly into the wall, and turn them off when you sleep. It estimates portable heaters cause about 1,600 fires, 70 deaths, and 150 injuries a year (2020 to 2022). A resident bringing a heater to a cold room is also telling you something about your heating. Fix the room HVAC and the heater often goes away. We ban space heaters in our co-living homes.

Lithium batteries. E-bikes and e-scooters are common in workforce houses, and they're the newest risk on this list. CPSC says never charge them while sleeping or away from home, and use only the charger approved for the device. It logged 156 fire and thermal reports tied to "universal" chargers from January 2023 to May 2024. London Fire Brigade adds that you should charge on a hard, flat surface, away from exits, with a smoke alarm in the area.

My rule: no e-bike or e-scooter batteries charging in bedrooms or hallways. Give residents a designated spot with a smoke alarm instead. A rule with nowhere to comply gets broken at midnight. A wheelchair or mobility scooter needs an individual conversation, not a blanket ban.

Smoking. Smoking is the leading cause of home fire deaths for adults 65 and over. If a resident uses medical oxygen, U.S. Fire Administration says never smoke where it's used, even when it's turned off. If you allow smoking outdoors, provide a sturdy ashtray in a set location.

Generators. After a storm, a resident may try to help. CPSC says generators belong outdoors, at least 20 feet from the home, never in a garage. No exceptions.

Doors and locks. If you use keypad locks on bedrooms, make sure they open from the inside without a key, and encourage closed bedroom doors at night. Keep a backup key or master code in a lockbox for emergency access.

Fire isn't the only emergency. Write one page per house, tailored to what's most likely where the house sits: wildfire, hurricane, tornado, flood, earthquake, or winter outage.

1. Who's in charge. Name the operator or property manager, with a 24-hour number. Name a house lead and a backup, by role rather than by assumption.

2. Where to go. Pick an outside meeting spot a safe distance from the house, where first responders can see you. Pick a second spot off the block for evacuations.

3. Getting out. Check your state and county evacuation zones and routes and write down the route plus one alternate. Plan who has no car and how they'll leave.

4. Staying in. For a tornado warning or an order to shelter in place, bring everyone inside, close windows and vents, shut off fans and forced air, and move to an interior room with few windows. Name that room in the plan.

5. Shutoffs. Show the locations of the electrical panel, water main, and gas meter, with a photo of each. Tell residents to leave gas to the utility or fire department unless they've been trained on it.

6. Getting alerts. Have everyone choose how they'll receive warnings. Sign up for your county's alert system, and post the sign-up link.

7. Contacts. Collect one emergency contact per resident at move-in, voluntarily. Store them where your manager can reach them when the Wi-Fi is down.

8. Residents who need more help. Ask every resident the same voluntary question: "Is there anything you'd want us to plan for in an emergency?" Let them decide what to share. Tell them they can inform the fire department about their needs.

9. The house kit. Keep it in a marked closet: water at one gallon per person per day for several days, non-perishable food, a manual can opener, a battery or hand-crank radio, flashlights, batteries, a first aid kit, phone power banks, and sanitation supplies. Each resident keeps their own medications, glasses, and copies of documents.

10. After the emergency. Say who calls the insurer, who documents damage with photos, and how residents get word about returning. Last week's [insurance issue, #030, https://shorturl.at/1HZQX] explains why you'll want this done fast.

A wall placard isn't required in most houses, but it puts the basics in front of residents when they need them. You have a few easy options.

Buy one. This ready-made placard is the simple route. If your house has residents who are more comfortable in another language, this similar bilingual version is a good fit.

Make your own. If you'd rather fill in details for each house, use the sample text below or print the free version: [https://shorturl.at/IjuTv]. Placard A works in the kitchen and by the main exit, and Placard B goes on the inside of each bedroom door.

PLACARD A: IN AN EMERGENCY AT [HOUSE NAME]

This address: ________________________________________ (read this to 911)

FIRE or SMOKE ALARM (3 beeps)

CARBON MONOXIDE ALARM (4 beeps)

EXTINGUISHER: ONLY IF ALL ARE TRUE The fire is small and in one spot. Everyone's been alerted. 911 has been called. Your way out is clear. You're able to use it. Pull the pin. Aim at the base. Squeeze slowly. Sweep side to side. When in doubt, get out.

Shelter room: ____________ Gas meter: ____________ Electric panel: ____________ Water main: ____________ House contact: ____________ Non-emergency fire line: ____________

PLACARD B: YOUR WAY OUT OF ROOM ____

If the door or handle is warm, don't open it. Use way out #2. If you can't get out, keep the door closed, seal the gap with a towel, call 911, and signal from the window. Stay low under smoke. Keep your phone, glasses, keys, and hearing aids within reach of your bed.

The beep patterns come from the American Red Cross. The extinguisher conditions come from the U.S. Fire Administration, and the room instructions from Ready.gov and the Red Cross. Some classifications require specific posted plans, so ask your fire marshal whether yours does.

Extinguishers in 55+ houses. Age alone shouldn't rule anyone out. I'd give every resident, whatever their age, a full explanation and hands-on training, so they know what the extinguisher can do and when to leave it alone. Be aware that USFA's list advises against older adults operating one. I think ability and training matter more than a birthday.

Whatever the resident's age, the priority stays the same: getting yourself out of the house matters more than fighting the fire. Find your way out first. An extinguisher is only for a small fire with a clear exit behind you, and never make using one a house duty.

The model fire code's drill table covers groups like hotels and college residence halls, and doesn't list R-3, so many ordinary houses have no drill mandate. Group homes and other classifications can differ, so check yours. The standard advice is to practice at least twice a year, day and night, using different exits. In a house with turnover, I'd add a walkthrough for every new resident in their first 24 hours.

Give notice, keep drills short, and make them a neighborly house meeting. A surprise 3 a.m. alarm will cost you residents, and for an older resident, a rushed trip down dark stairs is its own hazard.

Drill 1: The walkthrough (every move-in, 10 minutes). Show the new resident both ways out of their room, the meeting spot, the extinguishers, and the shutoffs. Press the test button so they know the sound. Have them sign the log.

Drill 2: Full fire drill (twice a year, 15 minutes). Press an alarm, everyone goes to the meeting spot, and you time it. Write the time down and try to beat it. Note who didn't hear the alarm, because that's the most useful finding you'll get.

Drill 3: Blocked exit, after dark (once a year, 15 minutes). Tell everyone the front door is "on fire" and they have to use the second way out. Ready.gov suggests feeling your way out in the dark. Open each bedroom window on the way. If a window sticks, fix it this week.

Drill 4: CO alarm tabletop (once a year, 10 minutes). Play the sound and walk through the steps. Stress the part people get wrong: CPSC says don't search for the source. Go out, call 911, and wait to be cleared.

Drill 5: Shelter and outage (once a year, 20 minutes). Gather in the shelter room, open the kit, and check the flashlights and water. Find the shutoffs together. Review the alert sign-up and evacuation route.

For hands-on extinguisher practice, call your local fire department and ask if they'll train your residents. A visit also starts a good relationship with the people who'd respond to your house.

Standard alarms don't reach every resident. Someone with high-frequency hearing loss, or someone who takes their hearing aids out at night, may sleep through one.

NFPA-sourced guidance describes three options: low-frequency sounders, strobe alarms, and bedside units with a bed shaker. For a resident who needs one, treat the request as a fair housing accommodation request and respond promptly. Your local attorney can tell you who pays and what you can ask.

For Silver Living houses, plan around each resident's ability. USFA says people 65 and older are twice as likely to be killed or injured by fire as the general population, and its advice is to "plan your escape around your abilities." That means clear hallways, good lighting, and a walker or wheelchair route that works without a helper.

Combination smoke and CO alarm, replaceable batteries. The practical choice for an older house with no alarm wiring, where your state allows replaceable batteries. [Smoke/CO alarms]

Combination smoke and CO alarm, wireless interconnect, sealed 10-year battery. The one to look for if your state requires sealed batteries on replacement alarms. Stay with one brand, because wireless alarms generally won't link across manufacturers. [Smoke/CO 10 year battery]

Standalone sealed 10-year alarm. Good for a spare room or a backup, but not where the code requires alarms to be interconnected. [Smoke/CO 10 year]

Hardwired interconnected alarm with battery backup. The like-for-like replacement if your house already has hardwired alarms. [Smoke/CO hardwired]

Fire extinguisher, 2-A:10-B:C. The size I'd put on each level. Look for a UL listing, a pressure gauge, and a wall bracket. Heavier units are harder to handle, so choose the largest size the user can operate comfortably. [Fire Extinguisher]

Fire extinguisher, 1-A:10-B:C. A lighter option for rooms or units where that rating is acceptable. [Fire Extinguisher]

Two-story escape ladder. An option for able-bodied residents in second-floor rooms with a usable window. Check the length, weight capacity, and sill fit. It isn't a plan for 55+ residents, and it doesn't fix a bad escape route. [Ladder]

Bedside alarm with bed shaker, or a strobe alarm. For residents who can't rely on sound. [Bed Alarm]

House kit and hallway basics: key lockbox [Lockbox], first aid kit [First Aid], LED flashlights [Flashlights], motion-sensor hallway lights [Hallway Lights]

Buying rule: No matter where you shop, look for the UL 217 and UL 2034 marks and a brand you can actually contact. A bargain 10-pack is how the alarms in our lead ended up on ceilings.
