An Act amending the act of November 10, 1999 (P.L.491, No.45), known as the Pennsylvania Construction Code Act, in preliminary provisions, further providing for definitions and for application.

SB 566 creates an exemption for "historical agricultural buildings" (structures built before January 1, 1999, for agricultural use that now host weddings and events) from most Pennsylvania construction code requirements. Owners must annually file an affidavit or undergo inspection confirming compliance with specific fire safety, electrical, and accessibility standards from the International Existing Building Code. Key provisions include requiring smoke detectors (hard-wired or battery-powered), portable fire extinguishers, occupancy signage, liability insurance, and prohibiting smoking and open flames - while exempting the building from needing automatic sprinklers. This bill directly affects owners of these pre-1999 agricultural buildings seeking to host public events without full modern code compliance.
