Smoke and carbon monoxide (CO) detectors save lives. That’s why we’re on a mission to get as many detectors into as many homes as possible. We encourage hosts to install smoke and carbon monoxide detectors in their space, test them regularly, and make sure their listing description is up to date.

Eligible hosts with an active listing can get a self-contained, battery powered, combination smoke and carbon monoxide detector at no cost through our Home Safety page (Home Safety Terms and Conditions apply).

While we encourage hosts to install smoke and carbon monoxide detectors in their space, at this time, we don’t require confirmation that they’ve been installed. Be sure to check your local regulations, which may require that you have more than one working smoke and carbon monoxide detector installed in your listing—for example, some cities require one in every room.

Information about whether or not a home has the safety measures guests expect, including smoke and carbon monoxide detectors, appears on the listing page and during the checkout process.

You can add or update these details in the Amenities section of your listing, found under Home Safety
