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

Lexington County Roofing Permit Requirements

Lexington County's Building and Safety Division handles permit requirements for construction and renovation projects. For properties located in unincorporated areas of Lexington County, the county's Building Codes Ordinance applies.

A building permit is generally required for any construction, enlargement, renovation, or change in occupancy of a building or structure. This includes the installation or replacement of electrical, gas, mechanical, or plumbing systems. Permits are also required for the installation or replacement of manufactured homes, regardless of cost.

Certain types of work are exempt from requiring a building permit. These include ordinary repairs and maintenance, fences, retaining walls (unless supporting a surcharge), water tanks, sidewalks, driveways, patios, painting, and other cosmetic finishes. Additionally, one-story detached storage structures under 200 square feet, shade cloth structures for nursery or agricultural purposes, and window awnings supported by an exterior wall do not require a permit.

Homeowners can obtain a permit to perform construction on their own residence if they plan to occupy it for at least two years after the final inspection. However, if a contractor is hired for work exceeding $200, they must be licensed by the South Carolina Department of Labor, Licensing and Regulations. It is often recommended that the contractor obtain the building permit to avoid homeowner liability for deficient work.

For projects in unincorporated areas, applicants must also meet zoning requirements before a permit can be issued. The Lexington County Zoning Ordinance specifically applies to these unincorporated areas, while municipalities have their own zoning regulations within their limits.

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.
