Alabama Hvac Legislation, Codes, and Guidelines

Overview of HVAC Building Codes in Alabama

Alabama does not have a single, mandatory statewide building code for all residential construction. Instead, the state operates under a decentralized system where building regulation is primarily handled at the local level. Cities and counties have the authority to choose whether to adopt and enforce specific building codes. Consequently, code requirements and the specific editions of codes enforced can vary significantly across different jurisdictions within the state.

Adopted Codes and Standards

While local adoption varies, many jurisdictions in Alabama utilize the International Codes (I-Codes) published by the International Code Council (ICC) as their baseline. For state-regulated buildings (such as state-funded projects), the Alabama Division of Construction Management (DCM) has adopted the 2021 editions of the International Building Code (IBC), International Mechanical Code (IMC), and other related standards. Additionally, the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR) mandates that all certified contractors adhere to specific minimum standards for installation, service, and repair, which include the International Mechanical Code, International Residential Code (IRC), International Fuel Gas Code, and the National Electrical Code (NFPA 70), among others.
