The state adopts by law the IBC and all codes referenced by the IBC except for Property Maintenance. Local jurisdictions can amend the state code to be more restrictive, but these ordinances can be appealed to the Secretary of Labor & Industry, who then holds a hearing and determines whether the local amendment will be allowed. The codes are updated following the issuance of new editions of the ICC codes every three years.

In accordance with the requirements of Act 45 of 1999 as amended, the Pennsylvania Uniform Construction Code (UCC) Review and Advisory Council (RAC) initiated review of the 2018 I-Codes on May 14, 2019. On April 29, 2021, the RAC submitted their report to the Pennsylvania Department of Labor & Industry which details the results of this voting process, thus ending this review period. The code provisions that were adopted during this process will take effect in the first quarter of 2022 (official effective date to be confirmed).
