Connecticut HVAC Building Codes and Legislation
The Connecticut State Building Code (CSBC) serves as the regulatory framework for all building construction, alteration, and equipment installation, including HVAC systems, across the state. The code is periodically updated to incorporate national model codes with Connecticut-specific amendments. As of early 2026, the state is in a transition period, with the 2026 Connecticut State Building Code—based on the 2024 International Code Council (ICC) family of codes—expected to take effect in mid-2026. Prior to this, projects are governed by the existing state building code, which is based on the 2021 International Code Council (ICC) model codes, including the International Mechanical Code (IMC), International Residential Code (IRC), and International Energy Conservation Code (IECC).
