The Carbon Monoxide Alarm Standards in Lodging Establishments Act establishes requirements for the installation and maintenance of carbon monoxide alarms in lodging establishments that utilize fossil-fuel-burning heaters, fireplaces, or appliances, or have attached garages. Under the new law, these establishments must have operational and approved carbon monoxide alarms installed in proximity to the heating sources and in every unit on the same floor within 18 months of the law's effective date. The act defines key terms such as "lodging establishment," "unit," and "operational," and clarifies that the owner is responsible for the maintenance, repair, or replacement of these alarms.

Additionally, the act imposes penalties for non-compliance, specifically a summary offense with a fine of up to $50 for willful failure to install or maintain the required alarms. The legislation does not alter the authority of the Department of Labor and Industry as outlined in the Pennsylvania Construction Code Act. The act is set to take effect immediately upon passage.
