Marion County, South Carolina Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Marion County Building Permit Requirements

Marion County, South Carolina, handles building permits for properties located in unincorporated areas. The Building & Inspections Department is responsible for enforcing building codes and issuing permits. Projects with a value exceeding $1,000 or covering an area of 200 square feet or more generally require a permit.

Before obtaining a construction permit, you will typically need to secure a zoning compliance permit. Additionally, proof of water/sewer tap payment (if applicable), a completed building permit application, and a signed contract agreement between the contractor and homeowner are required. Contractors must also present their South Carolina State Contractor's License and a Marion County business license.

For certain commercial buildings or those in high-wind zones, plans prepared by a licensed architect or registered engineer may be necessary.

Rules for Properties in Unincorporated Areas

Marion County issues building permits specifically for properties within its unincorporated areas. If your property is within the city limits of Mullins, Nichols, or Sellers, you will need to obtain your business license from that specific city.

The Building Inspection Division reviews construction and remodeling plans for unincorporated areas. For owner-builders constructing or improving a one- or two-family residence for personal use, a contractor's license is not required, provided they personally supervise the construction and do not sell or rent the property within two years of completion. However, they must file notice with the Register of Deeds.

Permits are generally required for new construction, additions, and moving structures. Driveways and sidewalks are typically exempt from building permit requirements.

South Carolina Roofing Legislation, Codes, and Guidelines

State Statutes and Adopted Building Codes

In South Carolina, building construction and safety standards are governed by statewide building codes adopted by the South Carolina Building Codes Council. These codes are based on the model codes published by the International Code Council (ICC), which the state adopts periodically with specific South Carolina amendments. As of the most recent major adoption cycle, the state utilizes the 2021 editions of the International Building Code (IBC) and the International Residential Code (IRC). Roofing requirements are specifically addressed within these codes—Chapter 15 of the IBC for commercial structures and Chapter 9 of the IRC for residential structures. These regulations establish minimum standards for roof assemblies, including materials, underlayment, flashing, fastening patterns, and wind resistance requirements.

Primary State Agency

The primary state body responsible for setting these standards is the South Carolina Building Codes Council, which operates under the South Carolina Department of Labor, Licensing and Regulation (LLR). The Council is a statutory body established under Title 6, Chapter 9 of the South Carolina Code of Laws. Its functions include adopting and modifying model building codes for statewide use, regulating the registration of building code enforcement officers, and overseeing the modular building program. While the Council sets the statewide minimum standards, local jurisdictions (counties and municipalities) are responsible for the enforcement, permitting, and inspection of roofing projects to ensure compliance with these codes.
