Home safety: Smoke and carbon monoxide alarms
Smoke and carbon monoxide (CO) alarms save lives. That’s why we’re on a mission to get as many alarms into as many homes as possible. We strongly urge Hosts to install smoke and carbon monoxide alarms in spaces that use fuel-burning appliances, test them regularly, and make sure their listing description is up to date.
Airbnb provides self-contained, battery powered, combination smoke and carbon monoxide alarms to eligible Hosts at no cost. Please check your local laws for applicable requirements for where to put alarms in your space.
Already have smoke and CO alarms?
Update information about safety devices such as smoke and carbon monoxide alarms on the listing page. Go to Listing details under Guest Safety on our website, or the Things your guests should know section on the Airbnb app.
If your place only uses electric appliances, and does not have an attached garage, you have the option to select that a carbon monoxide alarm is not necessary.
Be sure to check your local regulations, which may require that you have more than one working smoke and carbon monoxide alarm installed in your place.
