To ensure that certain short-term rentals are equipped with a smoke detector and a carbon monoxide detector, and for other purposes.

HR 3918 requires short-term rental properties (like Airbnb or vacation rentals) rented for less than 30 days to have both a smoke detector and a carbon monoxide detector. It directly affects hosts, property managers, and platforms facilitating these rentals, including single-family homes, condos, and time-shares rented to the public for fees. The bill mandates these detectors be installed before rental, with enforcement handled by the Federal Trade Commission (FTC) as part of its authority over unfair or deceptive practices. Violations could result in FTC penalties under existing law, and the requirement takes effect one year after the bill becomes law. The definition excludes meeting rooms, catering, or banquet services.
