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

Union County HVAC Permit Requirements

In Union County, Mississippi, building permits are generally required for major construction projects within unincorporated areas. This includes work related to HVAC systems, especially if it involves new construction, additions, or major renovations. It is crucial to verify the specific requirements with the Union County Board of Supervisors, as they handle permit procedures and provide application forms.

Mississippi state law (HB 1163) mandates that all counties issue permits for construction work, including HVAC installations, in unincorporated areas. Union County, like other Mississippi counties, must comply with state building codes, typically adopting one of the recent editions of the International Building Code (IBC) or International Residential Code (IRC), unless they have formally opted out by resolution. It is advisable to confirm the currently adopted code edition directly with the Board of Supervisors.
