Permit Requirements for Hanahan, South Carolina
For home remodeling and renovation projects in Hanahan, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Berkeley County.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Berkeley County:
- Within City Limits: The Hanahan Building Department typically oversees all Hanahan building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Hanahan boundaries are generally governed by the Berkeley County Building & Safety Division.
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.

South Carolina, Berkeley County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Berkeley County Building & Safety Division
The Berkeley County Building & Safety Division, also known as Building and Codes Enforcement, is the Authority Having Jurisdiction (AHJ) for building permits and inspections within the county. They enforce the latest South Carolina State adopted versions of the International Building Code, International Residential Code, International Mechanical Code, International Plumbing Code, International Gas Code, International Fire Code, International Energy Efficiency Code, and the National Electric Code.
Permit Requirements for Unincorporated Areas
For properties located in unincorporated areas of Berkeley County, a Permit Authorization Card (PAC Card) is required for all contractors. All individuals applying for or purchasing permits must comply with South Carolina's Labor and Licensing Regulations regarding proper licensing. State law requires residential construction to be performed by licensed residential builders and/or specialty contractors, with an exemption for property owners building or improving a one- or two-family residence for their own use and occupancy, provided it's not for sale or rent. Buildings or structures, excluding manufactured homes, moved into or within unincorporated areas require applicable building, electrical, mechanical, plumbing, and gas permits as if they were new construction.
Permit Triggers for Demolition Work
Demolition permits are required for demolition work in Berkeley County. To obtain a demolition permit, the property owner or contractor must complete a permit application. For mobile homes on rented lots, both the property owner and the owner of the dwelling must complete the application and provide a copy of the title. In cases of heir's property, the legal representative must apply or provide legal written notification, and the dwelling owner must complete the application. For abandoned and condemned properties, all demolition permits must be purchased. Verification that electrical service has been permanently disconnected by the power company is required. An inspection of the property is also required once debris is removed. Additionally, all permit holders are responsible for obtaining proper approval(s) from DHEC/State agencies regarding the demolition and disposal of demolished building or structure.
Permit Requirements for Non-Living Space Conversions
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. For example, any new garage construction, whether attached or detached, requires a building permit in Berkeley County. If a garage conversion involves adding electricity, plumbing, or mechanical systems, additional permits are required regardless of size. Structures larger than 200 square feet typically require a full building permit. For accessory structures like a room over a detached garage, built to residential standards, a permit may be required for occupancy while a primary residence is constructed, with specific conditions for vacating the accessory structure after the primary residence receives a certificate of occupancy. While specific definitions for attic or basement conversions are not explicitly detailed, the general principle is that any alteration or conversion that changes the use or occupancy of a space, or adds habitable square footage, will likely trigger the need for a building permit and associated inspections to ensure compliance with building codes.

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.
