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.
