Uniform Construction Code
These pages provide information regarding Pennsylvania's statewide building code, generally known as the Uniform Construction Code (UCC). Enforcement of the UCC began in April 2004.
New: Act 35 of 2017 and Act 36 of 2017 went into effect October 25, 2017. These acts amend the Pennsyvlania Construction Code Act. Please go to "Regulations and Statutes" for further information.
See "Codes and Standards Enforced Under the UCC" below for information about which version of the triennial codes applies to your construction project.
Administration and Enforcement of the UCC
Over 90% of Pennsylvania's 2,562 municipalities have elected to administer and enforce the UCC locally, using their own employees or via certified third party agencies (private code enforcement agencies) that they have retained. In these municipalities, the Department has no code enforcement authority, except where the municipality lacks the services of a person certified as an "Accessibility Inspector/Plans Examiner."
If a municipality has "opted out," the Department is responsible for all commercial code enforcement in that municipality. The Department also has sole jurisdiction for all elevators and all state-owned buildings, no matter where they are located.
Certified third party agencies hired by property owners (or their contractors) enforce the residential requirements of the UCC in all opt-out municipalities. Detailed information about these agencies can be accessed by clicking on the link below entitled "Certified Third Party Agencies: Buildings" (found under "Code Official and Third Party Agency Info").
A listing of all of Pennsylvania's municipalities and their decisions regarding local enforcement of the UCC can be accessed below by clicking on the link entitled "Municipal Elections and Contact Information" (under the "Local Enforcement" header).
Codes and Standards Enforced Under the UCC
As noted above, the codes applicable to work for which a construction permit is sought on or after January 1, 2016, are the 2009 International Codes issued by the International Code Council (ICC), and certain provisions from the 2015 International Codes. After April 16, 2016, Chapter 11 and Appendix E of the 2015 International Building Code and the accessibility provisions of the 2015 International Existing Building Code are applicable. Only these codes as first published and their errata are applicable in Pennsylvania. For further information about the codes and standards adopted, click on the UCC Codes button.
