We strongly encourage all hosts to install smoke and CO detectors in their listings, but we don't require hosts to show proof that they have these devices in their space right now. If you don't have a smoke or CO detector installed, you should mention this in your listing’s description.
If you're a host and already have these devices installed, update your listing description to let your guests know you have this important amenity installed.
Having working smoke and carbon monoxide (CO) detectors in your home can make a big difference. To help you get started, we're giving away one free combination smoke and carbon monoxide detector to the first 25,000 eligible hosts who request one through December 31, 2016.

Be sure to check you 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.
