Columbia, South Carolina Remodeler Local Permit Ordinances and Codes
Columbia, South Carolina Municipal Permit Ordinances for Remodelers and Home Renovations
The City of Columbia's Planning & Development Services department, specifically the Building Inspections Division and the Zoning Division, serves as the Authority Having Jurisdiction (AHJ) for building permits and renovation projects. They aim to provide an efficient and clear development review process.
Permit Triggers: Demolition vs. Standard Building Permit
In Columbia, South Carolina, a distinct demolition permit is required for the wrecking or removal of any load-supporting structural member of a facility, or any related handling of regulated asbestos-containing material. This differs from a standard residential building permit, which covers new construction, additions, and renovations. For demolition permits, specific submittal requirements include a commercial or residential permit application, a site plan, and a signed letter from the property owner approving the demolition. If the project is in a designated Historic or Design District, or in a floodplain, supplementary review requirements will apply.
Space Alterations: Converting Non-Living Spaces
Converting non-living spaces like basements or garages into habitable areas is subject to zoning and permit rules. The City of Columbia's Unified Development Ordinance (UDO) addresses accessory dwelling units (ADUs), which can include spaces within or attached to the principal structure, or detached structures like apartments above garages. The floor area of an ADU cannot exceed 1,000 square feet or 50% of the principal dwelling's floor area, excluding unfinished basements and carports. If attached, an ADU must have an operative interconnecting door with the principal structure. If detached, it must be at least ten feet from the principal structure and located in the same base zoning district. An ADU must also share utilities and driveways with the principal dwelling, unless accessed from a separate right-of-way. Only one kitchen is allowed per ADU, and they cannot be leased for tenancies of less than 30 days.
Fee Nuances and Inspection Stages
Permit fees in Columbia are generally based on the project's valuation. For residential projects, structural permit fees for alterations or repairs are calculated based on the fair market value. Commercial permit fees are determined by the greater of either the valuation based on the ICC Building Valuation Data Table or the value stated by the applicant. A plan review fee is typically required at the time of permit application, with specific amounts for residential and commercial projects. Inspections are a crucial part of the process, and they can be scheduled through the City's online Access portal. There is a cut-off time for next-day inspections, and same-day inspections are not available. Re-inspection fees apply if work is not ready or is disapproved.

Because Columbia is located within Richland County, the following broader county regulations may also apply to your project:
South Carolina, Richland County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Richland County Remodeling and Renovation Permit Requirements
The Building Permitting and Inspections Department of Richland County is the Authority Having Jurisdiction (AHJ) for building and safety matters within the county. They are responsible for issuing permits, enforcing building codes, and ensuring the safety and integrity of structures.
Unincorporated Areas
The Planning and Development Services Division of Richland County guides growth in unincorporated areas to protect public health and safety and ensure new development aligns with local ordinances.
Demolition Work During Remodels
Demolition of any regulated facility requires an ePermitting application to be submitted to the South Carolina Department of Environmental Services (SCDES) at least 10 working days in advance, even if asbestos is not present. A permit from the SCDES is required prior to demolition activity. Richland County may demolish abandoned or unsafe structures as a last resort if the owner fails to take action.
Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. Any associated plumbing, electrical, or mechanical work will also require separate permits.
- Garages: Converting a garage into living space requires a building permit. The new space must comply with current residential and energy codes. Alternative off-street parking may be required if parking spaces are removed. Building plans illustrating the proposed work, including floor plans, window and door openings, and locations of safety features like smoke alarms, are necessary.
- Attics and Basements: Habitable attics require vertical access and emergency escape and rescue openings. Unfinished basements may have specific code requirements for cable runs. In general, any alteration that creates habitable space will need to meet current building codes.
Specific requirements for these conversions, including necessary plans and safety features (like emergency escape and rescue openings), will be dictated by the South Carolina Building Codes, which are updated periodically. It is crucial to contact the Richland County Building Permitting Office to determine the exact requirements for your specific project.

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.
