South Carolina, Calhoun County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Calhoun County Building & Safety Jurisdiction
In Calhoun County, South Carolina, the Building and Planning Department is responsible for coordinating permitting and development for both residential and commercial interests. This department oversees code compliance and safety standards for properties located within the unincorporated areas of the county. If a property is located within the limits of an incorporated town, such as St. Matthews or Cameron, the respective town's building department—not the county—typically handles the permitting process.
HVAC Permit Requirements for Unincorporated Areas
A building permit is required for all construction in the unincorporated areas of Calhoun County, and this includes mechanical (HVAC) work. Permits must be issued by the county before any work commences. Key requirements and considerations for HVAC projects include:
- Licensing: Contractors and subcontractors must be licensed by the State of South Carolina and have their credentials on file with the Calhoun County Building Department.
- Technical Documentation: For HVAC installations, applicants must submit Manual J (load calculation) and Manual D (duct design) information with their plans. Manually computed Manual J forms are not accepted.
- Plan Details: Floor plans must clearly show the sizing and location of all ductwork, including branch lines to individual rooms, as well as the sizing, type, and location of the HVAC equipment to be used.
- Inspections: A series of inspections is required during construction. It is the responsibility of the contractor or owner to schedule these inspections with the Building Department, typically requiring at least 24 hours' notice.
- Homeowner Exemption: While homeowners may perform work on their own property, permits are still required. However, exemptions regarding licensed contractors do not apply to mechanical work; licensed professionals are required for these trades.
