Harrison County HVAC Permit Requirements
Harrison County, Mississippi, through its Code Administration division, requires permits for construction work, including HVAC installations and alterations. The county's Code Administration office is located at 15309 Community Road, Gulfport, MS 39503, and can be reached at (228) 832-1622.
For properties in unincorporated areas of Mississippi, including Harrison County, permitting is generally required as a condition of construction. While counties have the discretion to adopt building codes, they are mandated to require permits for construction within unincorporated areas.
Specific HVAC contractor licensing requirements in Mississippi depend on the project's value. For residential remodeling or repair projects exceeding $10,000, and for new residential construction or commercial projects exceeding $50,000, a state-issued HVAC contractor license is required. For projects below these thresholds, local jurisdictions may impose their own licensing and permitting requirements.
It is important to note that Mississippi law, specifically HB 1163, requires all cities and counties to issue permits for construction work. This legislation also mandates a state-issued license for residential subcontractors performing HVAC, electrical, plumbing, and/or mechanical work on residential construction or improvement projects, regardless of the work's value.
When applying for a permit in Harrison County, applicants will need to provide contractor information, including their state license number.

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.
