For properties in unincorporated Washington County, a permit is necessary for any new construction or substantial alterations. This includes work on HVAC systems. The application process typically involves contacting the Planning, Zoning & Engineering Department, providing contractor information (such as material purchase certificate number or Taxpayer Identification Number, and contractor's license number if applicable), detailing the project, and paying applicable fees.
Mississippi state law requires that contractors performing work over $50,000 on residential projects or $50,000 on commercial projects must hold a Mississippi contractor license. For HVAC work specifically, a license from the Mississippi State Board of Contractors (MSBOC) is generally required for projects valued over $10,000 for residential remodeling or over $50,000 for new residential construction or commercial projects. However, local jurisdictions may have their own licensing requirements for projects under these thresholds.
The Mississippi Building Codes Council has adopted the 2021 International Residential Code (IRC) and the 2021 International Building Code (IBC) as reference codes. It is advisable to confirm Washington County's specific adoption status of these codes with the Planning Department.

Mississippi HVAC Building Codes and Legislation
Mississippi utilizes a framework based on the International Code Council (ICC) standards for its building codes. The state generally adopts the International Mechanical Code (IMC) and the International Energy Conservation Code (IECC) to govern HVAC systems, often incorporating state-specific amendments to address the state's hot, humid climate and hurricane risks. While the state provides a base code framework, enforcement is primarily handled at the local level by municipalities and counties, which may choose to adopt and enforce these codes or establish their own local ordinances.
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.
