We ask that all listings be equipped with smoke alarms and carbon monoxide alarms if the listings have fuel burning devices. For active Airbnb Hosts, Airbnb will cover the cost of a carbon monoxide alarm (Hosts will be responsible for any custom taxes).

All Airbnb Hosts with an active listing can get a free smoke & carbon monoxide alarm. Each Host is limited to one alarm, but we strongly advise Hosts to install more alarms depending on the needs of your listing, and purchase additional alarms for any additional listings you have.

Exposure to carbon monoxide (CO) can lead to CO poisoning, which can be fatal. Carbon monoxide alarms are designed to alert you of high levels of the gas. We encourage every Host to understand the risks of CO exposure and install alarms to help keep guests safe. You can request one alarm from Airbnb if you have an active listing.

Airbnb does not require carbon monoxide detectors in all of its rentals, of which the company says there are over 4 million, in spaces from treehouses to mansions. The group's attorney, L. Chris Stewart of the Atlanta-based civil rights firm Stewart Miller Simmons says that Airbnb needs to immediately change its rules.

Be sure to check if a place has smoke and carbon monoxide alarms, both before booking and upon arrival. You can find this out in the list of amenities under Home safety. Carbon monoxide alarms aren’t common in many parts of the world, so we recommend bringing one with you, especially if the place you’re staying in doesn’t list one.
