Permit Requirements for Saint Matthews, South Carolina

For home remodeling and renovation projects in Saint Matthews, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Calhoun 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 Calhoun County:

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:

Note: Always consult the appropriate Saint Matthews or Calhoun County Authority Having Jurisdiction (AHJ) before beginning demolition or construction to ensure compliance with South Carolina amendments to the International Existing Building Code (IEBC) and avoid retroactive permitting fines.

Because Saint Matthews is located within Calhoun County, the following broader county regulations may also apply to your project:

Calhoun County, South Carolina Remodeling and Renovation Permit Requirements

Calhoun County's Building & Planning Department serves as the Authority Having Jurisdiction (AHJ) for building permits. They are responsible for ensuring that construction and renovation projects comply with the 2021 South Carolina Building Code, including any amendments. Permits are required for all construction activities in unincorporated Calhoun County.

Properties in Unincorporated Areas

A building permit is mandatory for all construction projects undertaken in the unincorporated areas of Calhoun County.

Demolition Work During Remodels

Demolition work during a remodel requires a specific demolition permit. The structure being demolished must be properly disposed of, and verification of this disposal must be submitted to the Calhoun County Building and Planning Department upon completion of the work.

Converting Non-Living Spaces to Habitable Areas

Converting spaces such as garages, attics, or unfinished basements into habitable living areas requires adherence to specific building codes and permit requirements. For garages, this includes ensuring separation from the residence and attic with appropriate fire-rated materials, and using solid wood or steel doors that are at least 1 3/8 inches thick or 20-minute fire-rated. No glass is permitted unless it is fire-rated.

For basements intended for habitable space, emergency escape and rescue openings are required. These openings must have a minimum openable area of 5.7 square feet, and the sash cannot be removed to meet this requirement. Grade floor windows have a slightly smaller exception at 5.0 square feet.

When converting any non-living space into a habitable area, plans must be submitted that clearly indicate the proposed changes, including floor plans, wall sections, and details for plumbing, electrical, and mechanical systems. The project must also meet energy code requirements, such as those outlined in the 2009 IECC (International Energy Conservation Code), and may require HVAC calculations (Manual J and D).

General Permit Application Process

To obtain a building permit, you will typically need to submit a completed Building Permit Application form, along with property owner consent (if applicable), an owner-builder affidavit (if applicable), contractor's license information, contractor and subcontractor lists, detailed plans, proof of wastewater disposal system verification (septic permit or public sewer availability), and potentially other affidavits depending on the project (e.g., restrictive covenants, roofing).

Plans should be drawn to scale and include site plans showing setbacks, driveways, and other structures. The Building and Planning Department conducts a plan review for code compliance, which typically takes 10-15 days. Permits are issued once plans are approved, and the permit card must be posted on-site before work commences.

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.
