Mississippi HVAC Building Codes and Legislation
Mississippi utilizes a framework based on the International Code Council (ICC) standards for its building codes.

Primary Regulatory Agencies and Boards
The regulation of HVAC in Mississippi is divided between building code standards and contractor licensing:
- Mississippi Building Code Council (MBCC): This body is responsible for the adoption and updating of the state's building codes, including the mechanical and energy codes, on a multi-year cycle.
- Mississippi State Board of Contractors (MSBOC): This board administers the licensing requirements for HVAC and mechanical contractors. State law requires contractors to hold a license for HVAC work exceeding specific dollar thresholds ($10,000 for residential remodeling and $50,000 for new residential or commercial construction).
- Office of the State Fire Marshal: This office is responsible for enforcing the Mississippi Fire Prevention Code, which includes standards relevant to mechanical and HVAC systems in specific types of buildings, such as state-owned facilities, public assembly buildings, and high-rise structures.
