The Fuel Gas Detector Act mandates the installation and maintenance of fuel gas detectors in both residential and commercial buildings in Pennsylvania. Building owners are required to install these detectors in any room containing appliances that combust propane, natural gas, or liquefied petroleum gas, ensuring compliance with the manufacturer's requirements. For residential buildings, landlords must provide functioning fuel gas detectors at the time of occupancy and address any deficiencies reported by tenants. Additionally, individuals acquiring residential buildings after January 1, 2027, must install fuel gas detectors within 30 days of acquisition if they are not already present.

The act also outlines enforcement mechanisms, allowing municipalities to inspect buildings and impose civil penalties of up to $500 for violations. It provides liability protections for property owners who comply with the installation and maintenance requirements, as long as they conduct necessary inspections and are not notified of any defects. Furthermore, the act prohibits interference with the operation of fuel gas detectors, except under specific circumstances related to construction or rehabilitation activities. The law is set to take effect 120 days after its enactment.
