Requires explosive gas detectors to be installed in certain residential properties.

This bill requires owners of residential properties with fewer than three dwelling units (like single-family homes or duplexes) to install carbon monoxide and explosive gas detectors before selling, leasing, or changing occupancy. It applies during certificate of occupancy issuance or when new tenants move in, with exemptions if no gas or carbon monoxide hazards exist. Detectors must meet specific safety standards (UL 2034 for carbon monoxide, ANSI for gas detection), and owners who fail to comply face fines up to $100. The law also extends similar requirements to hotels, multiple dwellings, and rooming houses.
