South Carolina, McCormick County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

McCormick County HVAC Permit Requirements

McCormick County requires building permits for various projects, including mechanical, electrical, and plumbing installations, which would encompass HVAC systems. Permits are necessary for new buildings, additions, alterations, demolitions, and significant structural changes to roofing. Even structures that may be exempt from a building permit might still need to comply with zoning and planning requirements.

All contractors working in McCormick County must hold a valid South Carolina State Contractor's License, unless the project is residential construction being performed by the owner-builder. Subcontractors are also required to provide a copy of their South Carolina Contractor License before a permit can be issued.

County Jurisdiction and Unincorporated Areas

McCormick County's Building Department, located at 610 South Mine Street, McCormick, SC 29835, handles permit applications and inspections for all unincorporated areas of the county. The Zoning Department, also located at 610 South Mine Street, should be contacted prior to beginning any project to verify zoning compliance and identify any necessary special permits. Some projects that might not require a building permit could still necessitate a zoning permit.

Application Process

County staff will review the plans for compliance with the SC Building Code 2021 and local ordinances. Inspections can be scheduled by calling (864) 852-2231, with requests needing to be submitted by 2:00 PM for the next business day's inspection.

South Carolina Hvac Legislation, Codes, and Guidelines

State Statutes and Adopted HVAC Codes

In South Carolina, building codes are mandated by the state legislature and enforced at the local level. The state utilizes the International Code Council (ICC) family of codes as the foundation for its statewide standards. As of the most recent major update effective January 1, 2023, South Carolina has adopted the 2021 editions of the International Codes, including the International Mechanical Code (IMC) and the International Residential Code (IRC), with specific South Carolina-approved modifications. These codes establish the minimum requirements for the design, installation, maintenance, and inspection of HVAC systems in residential, commercial, and industrial buildings.

Primary State Agency

The South Carolina Building Codes Council is the primary state body responsible for adopting, modifying, and overseeing the implementation of these building codes. The Council, which operates under the South Carolina Department of Labor, Licensing and Regulation (LLR), reviews ICC code editions and determines necessary state-specific amendments to address local environmental and construction conditions. While the Council sets the standards, the actual enforcement of these codes is carried out by local jurisdictions (cities and counties), which are required to employ certified building officials to conduct plan reviews and field inspections.
