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

Lamar County HVAC Permit Requirements

Lamar County, Mississippi, requires construction permits for residential projects within its unincorporated areas. These permits are mandated by House Bill 1163, enacted in the 2022 session of the Mississippi State Legislature. The Lamar County Board of Supervisors adopted the Residential Construction Permitting Ordinance on July 5, 2022, with the ordinance taking effect on August 5, 2022.

For any structure requiring a utility of any type, a Flood Permit is also necessary in Lamar County's unincorporated areas.

County Building & Safety Divisions and Jurisdiction

Lamar County's Planning Department, under the Board of Supervisors, is responsible for administering various ordinances, including those related to development and construction within the county. While the county has ordinances to ensure development aligns with approved plans, it's important to note that Lamar County has not adopted structural building codes and does not conduct structural inspections in its unincorporated areas.

Rules for Properties in Unincorporated Areas

In unincorporated areas of Lamar County, a residential construction permit is required for any residential project meeting specific guidelines established by state statutes. This includes new structures, expansions, or remodels where the project value exceeds certain thresholds (e.g., $10,000 for expansions/remodels). If a general contractor is not used, each individual trade, including HVAC, will need to obtain its own permit. Contractors and subcontractors must be licensed by the Mississippi State Board of Contractors.

For HVAC work, if the job contract value is $10,000.00 or more, a Mississippi State HVAC Contractors License is generally required. If the contract value is less than $10,000.00, a valid HVAC contractor's license from another jurisdiction may be accepted, and proof of general liability insurance is also required.

The permit fee for residential construction in Lamar County is a flat fee of $50.00, payable at the time of application.

For specific questions or assistance with filing or obtaining a permit in unincorporated areas of Lamar County, individuals should contact the Planning Department at 601.794.1024 during normal business hours.

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.
