Chairman’s Message: Residential Sprinkler Installation in PennsylvaniaDecember 2010 – Newsletters In the Zone
The 2009 International Residential Code (IRC) mandates the installation of automatic fire sprinkler systems in new townhouses and in new one- and two-family dwellings. The compliance date for new one- and two-family dwellings is January 1, 2011. There are two exceptions to these requirements: (1) if a design contract or a construction contract for the construction of these dwellings was signed prior to December 31, 2009, the work will comply with the 2006 International Residential Code; and (2) if an application is submitted for a UCC building permit prior to either of the effective dates of the sprinkler requirement, the residential construction will not be subject to it. The specific requirements for the design and installation of sprinklers in townhouses are found in section P2904 in the IRC. The design and installation of sprinkler systems in one- and two-family dwellings can comply with P2904 or NFPA standard 13D.
