The 2021 South Carolina Residential Code (SCRC) governs nearly all aspects of residential construction in South Carolina, including the construction, alteration, movement, enlargement, replacement, repair, equipment, use, occupancy, location, removal, and demolition of:

• Detached one- and two-family dwellings
• Townhouses (up to three stories above grade plane, with a separate means of egress)
• Accessory structures (also up to three stories)

Notably, certain building types—such as live/work units, owner-occupied lodging houses with five or fewer guestrooms, and small care facilities—may follow reduced requirements under specific conditions, particularly when equipped with an approved automatic sprinkler system as outlined in Section P2904.

The practical application of the 2021 South Carolina Residential Code (SCRC) is to provide a clear, enforceable framework for the safe design, construction, renovation, and inspection of residential buildings across South Carolina. It is used daily by builders, architects, engineers, inspectors, and contractors to ensure that all aspects of residential construction—such as foundations, framing, plumbing, electrical, energy efficiency, fire safety, and egress—meet minimum code standards. This code applies to:

• New construction of one- and two-family homes and townhouses (up to three stories)
• Additions, repairs, and remodels of existing residential structures
• Accessory buildings like garages, sheds, and detached units
• Tiny homes, using specific guidelines in Appendix AQ

Local building inspectors use the SCRC to evaluate compliance during key construction phases, from foundation to final inspection. Contractors refer to it to ensure materials and installation methods meet safety and structural requirements. For homeowners and developers, it ensures that projects are built to protect health, safety, and property, while also complying with state law. In real-world use, the SCRC helps prevent construction errors, promotes energy-efficient practices, ensures proper emergency exits, and protects occupants and first responders in the event of a fire or structural failure.
