Uniform Construction Code
Construction in Pennsylvania, including the City of Pittsburgh, is regulated by the Pennsylvania Construction Code Act or PA Act No. 45 of 1999, which is also commonly referred to as Uniform Construction Code (UCC). The UCC adopts, in whole or part, the International Code Council’s (ICC) I-Codes.
The Pennsylvania Department of Labor and Industry is responsible for publishing UCC Regulations. Section 403.21 of UCC Regulations identifies adopted codes, refer to this excerpt which highlights the adopted codes. Please note that the 2018 IBC references the 2009 ICC A117.1 Accessible and Usable Buildings and Facilities.
City of Pittsburgh adoption and amendment of the UCC is documented under Section 1002 of the Pittsburgh City Code. These local amendments remain applicable as the UCC is updated by the Commonwealth. While the City Ordinances reference specific 2003 I-code code sections, these amendments are enforced by PLI based on the code provision and/or topic.
Please note that PLI does not enforce the plumbing code provisions of the UCC. Please see Allegheny County Health Department’s Plumbing Program for plumbing code permits and regulations.
