How often should you do a home safety check?
Test smoke alarms once a month, check carbon monoxide alarm batteries twice a year when the clocks change, service the furnace and replace smoke alarm batteries once a year, replace smoke alarms every 10 years, and walk the house for trip hazards at least twice a year.
The alarm timings come from the U.S. Fire Administration (2026) and the CDC (2017). The twice-a-year walk is our suggestion, because no official source we found gives a number for it. Tie it to the clock change and it rides along with the CO battery check.
The questions people actually ask, answered like a text thread
Smoke alarm. How often do I really need to press the button?
Once a month. USFA (2026): "Test the alarm monthly." Same for 9-volt, hardwired and 10-year sealed alarms.
And the batteries?
At least once a year for 9-volt batteries and for the backup battery in hardwired alarms. Sealed 10-year alarms have no battery to change; you replace the whole alarm per the maker.
Carbon monoxide too?
Check or replace the CO detector battery when the clocks change each spring and fall, says the CDC (2017). The clocks went back on November 1, 2026. Next change: March 14, 2027.
The furnace is fine, it's working.
Working isn't the test. The CDC says to have the heating system, water heater and other gas, oil or coal burning appliances serviced by a qualified technician every year.
What about rugs and cords and dark hallways?
No set number from the CDC or NIA. We'd say twice a year, plus after any change in how someone gets around. NIA (reviewed 2022) suggests light switches at the top and bottom of stairs, and holding the handrail even when carrying something.
I can't always hear high beeps anymore.
The USFA page mentions smoke alarms with strobe lights or vibration for people with hearing loss. Worth asking your local fire department about.
I fixed the loose rug last week. Done?
Mostly. Rugs creep back. RoomMend plans a reminder to look again 30 days after you tick a fix done, which is the whole reason we built it.
A November afternoon (a story we wrote)
He is 81 and lives alone in a two-floor house. The clocks went back on Sunday. On Monday his son calls, and they do it on speakerphone: press the test button on each smoke alarm, check the CO detector's battery, look at the sticker on the furnace for the last service date. The upstairs alarm chirps weakly. The furnace sticker says two winters ago.
The son logs both in RoomMend under Hallway and Utility, marked This week, and books the furnace service while they are still on the phone. Thirty days after he ticks them done, RoomMend asks him to look again. The new battery is fine. The furnace has a fresh sticker.
Honest limits
- RoomMend organizes your notes and plans. It is not a home inspection, safety certification or fall-risk assessment, and it does not detect hazards in photos.
- It cannot test, hear or monitor alarms. You press the button.
- For electrical, gas, structural or fire-safety concerns, call a qualified professional.
- Free: every walkthrough, unlimited rooms and notes, the fix list, reminders, rechecks and room PDFs. RoomMend Plus is a one-time purchase for more homes, more photos, the whole-home binder PDF and the full timeline.
Home safety check FAQ
How often should you test smoke alarms?
Monthly. The U.S. Fire Administration (page reviewed 2026) says to test the alarm monthly, replace 9-volt or backup batteries at least once a year, and replace the whole alarm every 10 years.
When should I change carbon monoxide detector batteries?
The CDC's carbon monoxide prevention guidelines (2017) say to check or replace the battery when you change the time on your clocks each spring and fall. In the US the next change is Sunday, March 14, 2027.
How often should a home be checked for fall hazards?
No federal guide we found sets a number. We suggest a room-by-room walk twice a year at the clock changes, plus after anything that changes how someone moves: a new walker, surgery, a fall, new glasses or a new pet. The CDC Check for Safety brochure and NIA's room-by-room page are good free guides for the walk.
How often should the furnace be inspected?
Every year. The CDC (2017) says to have your heating system, water heater and any other gas, oil or coal burning appliances serviced by a qualified technician every year.
How long do smoke alarms last?
The USFA says to replace 9-volt and hardwired alarms every 10 years. Alarms with sealed 10-year lithium batteries are replaced according to the manufacturer's instructions.
Can RoomMend remind me about these checks?
Partly. RoomMend has an "Alarm to test" issue you can log in any room with a This week, This month or Someday label and an optional reminder, and it plans a recheck 30 days after you tick a fix done. It is a notebook, not a monitoring system: it cannot hear or test your alarms.
Your home safety check schedule, in one table
| How often | Check | Source |
|---|---|---|
| Monthly | Press the test button on every smoke alarm | USFA, 2026 |
| Spring + fall | Check or replace CO detector batteries at the clock change | CDC, 2017 |
| Spring + fall | Walk each room for rugs, cords, dark spots, hard-to-reach shelves | Our suggestion |
| Yearly | Replace 9-volt or backup batteries in smoke alarms | USFA, 2026 |
| Yearly | Service the heating system, water heater and fuel-burning appliances | CDC, 2017 |
| 10 years | Replace 9-volt and hardwired smoke alarms | USFA, 2026 |
| 30 days after a fix | Look again to see it held | How RoomMend works |
Monthly for alarms. Twice a year for the house. Every time something changes.
One design decision we made: RoomMend's home screen shows a single next step, not this whole table. Twenty checks on one screen is how the clipboard ends up in a drawer.
Who RoomMend is not for
If you want sensors that detect a fall, smoke or a water leak and alert someone, look at a monitored alarm service or smart home devices; RoomMend does neither. If you need a professional opinion for a mortgage, insurance or a sale, book a licensed home inspector. And if a paper calendar on the fridge already works for you, keep it.
