Mississippi, Tallahatchie County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Tallahatchie County HVAC Permit Requirements
Tallahatchie County, Mississippi, requires building permits for all construction in unincorporated areas, including HVAC work. Mississippi Code § 19-5-9 mandates permitting for new construction, additions, substantial alterations, demolition, relocation, and any construction within a FEMA-designated Special Flood Hazard Area.
While Mississippi has adopted various International Building Codes, including the International Mechanical Code (IMC), Tallahatchie County has not publicly adopted the International Building Code (IBC) or International Residential Code (IRC) for its unincorporated areas. It is advisable to confirm the current adoption status with the Board of Supervisors.
For properties in unincorporated areas, the Board of Supervisors or its designated agent reviews permit applications. To obtain a building permit application form, contact the Chancery Clerk's office in Charleston at (662) 647-5551 or Sumner at (662) 375-8731.
Contractors performing HVAC work may need to be licensed by the Mississippi State Board of Contractors (MSBOC) if the contract value exceeds certain thresholds: $50,000 for commercial projects and $10,000 for residential remodeling projects. However, HB 1163, effective July 1, 2022, requires a state-issued license for residential subcontractors performing HVAC work on any residential construction or improvement project, regardless of the cost.
It is important to note that while state licensing requirements establish minimum qualifications, local jurisdictions can impose additional permitting, inspection, or code requirements.

Mississippi Hvac Legislation, Codes, and Guidelines
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.
