Mississippi, Franklin County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

Franklin County HVAC Permit Requirements

Franklin County, Mississippi, through its Board of Supervisors, has the authority to adopt building codes that apply to unincorporated areas. These codes are intended to establish minimum requirements to safeguard public safety, health, and general welfare. The county has adopted various International Codes, including the International Mechanical Code (2021 edition) and the National Electric Code (2020 edition). HVAC work typically falls under the purview of these adopted codes.

County-Level Jurisdiction and Unincorporated Areas

Franklin County's Building Department is responsible for issuing permits and conducting inspections for new construction within the unincorporated areas of the county. This includes ensuring compliance with adopted building codes. Mississippi law (Title 19, Chapter 5, Section 9) explicitly states that any codes adopted by a county board of supervisors shall apply only to the unincorporated areas of that county. Furthermore, Mississippi law mandates that all counties require permitting as a condition for construction within unincorporated areas, regardless of whether specific codes have been adopted.
