What this checker looks for
This tool helps renters think through common CO alarm gaps: missing alarms, blocked alarms, chirping alarms, unknown product instructions, fuel-burning appliances, attached garages, and whether everyone knows what to do when an alarm sounds.
What to do if your result is low
- Do not ignore a chirping, missing, damaged, or expired alarm.
- Report problems to your landlord or property manager in writing when possible.
- Check the alarm manufacturer instructions for placement guidance.
- Ask your local fire department or housing authority where to find local CO alarm requirements.
- Leave immediately if a CO alarm sounds. Do not stay inside to troubleshoot.
