BUILDING CODES: Requires gas detection devices in homes with gas appliances

This bill requires homes with gas appliances to install fuel gas alarms that detect leaks and sound an alarm. It applies to single-family and multi-family residences connected to natural gas or propane services, while exempting licensed residential care facilities from new enforcement rules. The law mandates that these alarms be tested by independent labs and installed according to manufacturer instructions, with the fire marshal allowed to create specific placement rules. Enforcement will only happen during existing building or fire safety inspections, and violations will initially result in a written warning rather than immediate penalties. The requirements are scheduled to take effect on January 1, 2030.
