Pennsylvania HVAC Building Codes and Legislation

Building construction and HVAC systems in Pennsylvania are regulated under the Pennsylvania Uniform Construction Code (UCC), which was established by the Pennsylvania Construction Code Act (Act 45 of 1999). The UCC mandates a statewide building code, though over 90% of municipalities have elected to administer and enforce these codes locally, either through their own employees or certified third-party agencies.

As of January 1, 2026, Pennsylvania has adopted the 2021 International Codes (I-Codes) as the base for the UCC. These codes, which include the International Mechanical Code (IMC), International Residential Code (IRC), and International Energy Conservation Code (IECC), set the standards for HVAC system design, installation, efficiency, and safety. It is important to note that while the state adopts these standards, the UCC Review and Advisory Council (RAC) may recommend specific amendments to these codes for Pennsylvania, and local municipalities may have additional ordinances.
