Common Remodeling Permit Triggers
Remodeling is a broad category, and permit requirements depend heavily on the scope of your work. While cosmetic updates—such as painting, installing new flooring, or replacing like-for-like kitchen cabinets—generally do not require approval in South Carolina, you will almost certainly need a permit for the following:
- Space Conversions: Altering non-living spaces (such as finishing a basement, finishing an attic, or converting a garage) into habitable living areas.
- Structural Changes: Removing, adding, or modifying load-bearing walls, headers, or the roofline.
- Demolition: Extensive interior renovations or "gutting" a space often requires a specific demolition permit prior to or concurrent with the standard building permit.
- Systems Alterations: Rerouting plumbing pipes, adding new electrical circuits, or moving HVAC ductwork.

Horry County Building & Safety Division
The Horry County Code Enforcement Division is the Authority Having Jurisdiction (AHJ) for building permits and inspections in the unincorporated areas of Horry County, South Carolina. They are responsible for ensuring that new construction and improvements comply with adopted building codes, safety standards, and zoning regulations.
Permit Requirements for Unincorporated Areas
In unincorporated Horry County, a building permit is generally required for any owner or authorized agent intending to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure. This also applies to the installation, enlargement, alteration, repair, removal, conversion, or replacement of electrical, gas, mechanical, or plumbing systems. A permit is required when the cost of construction or improvement to any building exceeds five hundred dollars ($500.00), including materials and labor.
Certain projects are exempt from requiring a building permit, including:
- One-story detached accessory structures not exceeding 200 square feet (zoning compliance may still be required).
- Fences not exceeding 7 feet in height.
- Retaining walls not exceeding 4 feet in height (unless supporting a surcharge).
- Painting, tiling, carpeting, cabinets, countertops, and similar finish work.

Permit Triggers for Demolition Work
Demolition work on a building or structure requires a permit in Horry County. The requirements for a demolition permit include a completed application, a scope of work description, and notarized authorization from the property owner.
Permit Requirements for Converting Non-Living Spaces
Altering or converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas typically requires a building permit. This is because such conversions often involve structural changes, electrical, plumbing, or mechanical system modifications, which are regulated by building codes. For example, converting a garage into a living space would necessitate a permit as it constitutes a change in occupancy and potentially structural alterations.

The following statewide building codes and regulations apply universally to all jurisdictions within South Carolina:
South Carolina Remodeler Legislation, Codes, and Guidelines
South Carolina Building Codes and Renovation Regulations
In South Carolina, the regulation of building codes and residential renovations is overseen by the South Carolina Building Codes Council. This council is responsible for adopting and modifying model building codes for the state, ensuring that construction and renovation projects meet minimum safety and quality standards. The state mandates the use of codes developed by the International Code Council (ICC), with specific South Carolina modifications. The most current adopted codes are the 2021 International Codes, which became effective on January 1, 2023.
1. Adopted State Statutes and Codes
South Carolina has adopted the 2021 International Building Code (IBC) and the 2021 International Residential Code (IRC), along with their respective South Carolina modifications. The state also adopts other International Codes, including the Fire Code, Plumbing Code, Mechanical Code, Fuel Gas Code, and Energy Conservation Code. While the International Existing Building Code (IEBC) is mentioned as a "permissive code" that local governments may adopt, it is not explicitly listed as a mandatory statewide adoption for all renovations in the same way as the IBC and IRC.
2. Primary State Board or Agencies
The South Carolina Building Codes Council is the primary state agency responsible for setting and adopting building standards. This council is composed of public and private building industry officials appointed by the governor. The South Carolina Department of Labor, Licensing and Regulation (SCLLR) also plays a role, particularly through the South Carolina Residential Builders Commission, which oversees licensing and registration for remodelers and contractors.
3. Classification of Remodels and Demolition Guidelines
South Carolina law requires building permits for any construction, enlargement, alteration, repair, movement, or demolition of a building, as well as for the installation or alteration of electrical, plumbing, or mechanical systems.
- Cosmetic Remodels vs. Structural Alterations: Generally, cosmetic updates such as painting, replacing countertops in the same location, refinishing floors, or swapping like-for-like appliances typically do not require a permit. However, alterations that involve moving walls, rerouting gas lines, adding new electrical circuits, or relocating pipes are considered structural changes and necessitate a permit. Finishing basements, enclosing porches, building decks, adding air conditioning or new gas lines, or converting attics also significantly affect the home's structure and require permits.
- Demolition Guidelines: Demolition projects in South Carolina are subject to specific notification and permit requirements. Before demolition, an asbestos inspection by a certified inspector is generally mandatory. A minimum advance notification period (often 10 working days) is typically required before demolition or renovation work that could disturb asbestos. Written notification must be submitted to the South Carolina Department of Environmental Services (DES), formerly part of DHEC. Specific demolition permits may also be required from state and local authorities. Residential demolitions of single-family homes or duplexes may be exempt under certain conditions, unless they are part of a larger commercial project or involve multiple units under a single owner.
