How many smoke detectors does my home need?


The National Fire Protection Association (NFPA) established a baseline for the number of devices a home needs to get during smoke detector installation. They recommend:

  • One smoke alarm per bedroom
  • One smoke/Carbon Monoxide (CO) alarm outside every bedroom or sleeping area
  • One smoke/CO detector on every story of the house, basement included
  • If you own a two-story house with four bedrooms all on one floor, that’s a minimum of six smoke alarms — seven, if you have a basement.

For those more inclined to specific measurements, the NFPA has more exact guidelines. A smoke alarm covers a radius of 21 feet, covering 1,385 square feet. They recommend that two smoke alarms have a maximum distance of 30 feet between them — meaning if you have a 50-foot hallway, one smoke alarm should be placed at either end.

Officials also recommend keeping smoke alarms away from kitchens and bathrooms, since those rooms often generate smoke and heat that can trip smoke alarms. Although that’s a great reassurance that they’re working properly, it can get to be a nuisance.


Smoke Detector Maintenance

Smoke detectors can make the difference between fleeing a building fire in time and becoming overwhelmed by smoke and fumes. Make sure that yours are always in working order.


Carbon Monoxide Detectors

While smoke detectors are mandatory throughout the country, carbon monoxide detectors are merely strongly recommended. This does not make them any less valuable. Carbon monoxide is one of the most common types of poisoning in the US, sending more than 20,000 people to the emergency room each year. If undetected, a carbon monoxide leak can become lethal within minutes.

Frequent Questions


Where should smoke detectors be located?

Install smoke alarms inside each bedroom, outside each sleeping area, and on every level of the home, including the basement. On levels without bedrooms, install alarms in the living room (or den or family room) or near the stairway to the upper level, or in both locations.


Should smoke detectors be on the ceiling or wall?

Smoke alarms should be mounted in or near bedrooms and living areas, either on the ceiling or the wall. Ceiling mounting it is typically preferred, as it allows the smoke alarm to be placed more centrally in the room.


Why do my smoke alarms keep going off for no reason?

The most likely reason smoke detectors go off unexpectedly is that people aren’t changing the batteries in them often enough. That’s because smoke in the air will reduce the current. If your battery is dying, the current that’s flowing through your sensor also goes down. And so you can get a false positive.


What is the electrical code for smoke detectors?

NFPA 72, the National Fire Alarm Code, requires smoke detectors (alarms) to be installed in all sleeping rooms of the dwelling (except in existing dwellings not previously wired for smoke detection).
