Airbnb and short-term rental platforms have transformed travel — but they've also created a new category of accommodation that sits outside many of the safety regulations that govern traditional hotels.

The Regulatory Gap

Airbnb only requires hosts to disclose whether a CO detector is present — not to have one verified or inspected. A consumer safety study found 62% of inspected short-term rentals lacked verified CO protection.

Traditional hotels are subject to state and local fire codes, health department inspections, and in many jurisdictions, mandatory CO detector requirements. Airbnb properties are private homes — they're governed by local residential codes, which vary enormously, and are rarely inspected between guests.

  • Airbnb's policy requires hosts to disclose whether CO detectors are present — but does not mandate them
  • A disclosed detector may be present but expired, improperly placed, or non-functional
  • 62% of short-term rentals inspected in a 2022 consumer safety study lacked verified CO protection
  • Host compliance with local codes is largely self-reported
📋 Airbnb's platform shows a 'CO detector' badge on listings where hosts have confirmed one is present. This is self-reported and unverified. Treat it as a starting point, not a guarantee.

The 7-Point Arrival Checklist

Every short-term rental check-in should include: locating and testing the CO detector, checking its expiration date, confirming placement near sleeping areas, identifying fuel-burning appliances, checking vent clearances, locating exits, and plugging in your own portable detector.

Run through this checklist every time you check into a short-term rental:

  • 1. Locate and test the CO detector — find it, press the test button, confirm it beeps
  • 2. Check the expiration date — CO detectors have a 5-10 year lifespan; the date is usually on the back
  • 3. Check placement — CO detectors should be at breathing height, near sleeping areas
  • 4. Identify fuel-burning appliances — gas stove, furnace, water heater, fireplace
  • 5. Inspect ventilation around appliances — blocked vents are a red flag
  • 6. Locate the nearest exit from the bedroom and count doors to the exit
  • 7. Plug in your own portable detector near where you'll sleep

When There's No Detector

If no detector is present despite the listing claiming one, contact the host, report to Airbnb support as a platform violation, and rely on your own portable detector — do not assume the space is safe without independent verification.

If you arrive and there's no CO detector present despite the listing claiming one, or if you can't verify any detector is functional, you have a few options:

  • Contact the host immediately — a responsible host will address this
  • Contact Airbnb support — non-disclosure of amenities is a platform violation
  • Use your own portable detector in the meantime — this is the simplest fallback
  • If you don't have your own detector and feel unsafe, request a refund due to health and safety concerns

Protecting Yourself Regardless of Host Compliance

Carry your own portable CO detector on every trip — it gives you an independent live PPM reading within seconds of plugging in, regardless of what the host disclosed or what a wall-mounted alarm may or may not do.

The most reliable approach is to carry a portable CO detector on every trip. A device the size of a TV remote plugs into any outlet and gives you a real-time PPM reading within seconds of arriving. You don't have to trust the host's compliance, the listing's accuracy, or the local inspection schedule. You have your own data.
