Dorchester County Building & Safety Divisions
The Dorchester County Building Services Department is the primary authority responsible for the issuance of building permits and the enforcement of building codes for both residential and commercial projects. This department oversees the permitting process, including for mechanical, electrical, and plumbing work, and conducts field inspections to ensure compliance with adopted codes. The department is located at 500 N. Main St., Summerville, SC 29483, and can be reached at (843) 832-0011.
Rules for Properties in Unincorporated Areas
Permit requirements in Dorchester County apply specifically to properties located in unincorporated areas of the county. If a property is located within an incorporated municipality (such as Summerville, North Charleston, St. George, or Ridgeville), that municipality may have its own separate permitting authority and requirements. For projects in unincorporated Dorchester County, the following applies:
- Permit Necessity: HVAC work, including installations and replacements, generally requires a permit. These are often categorized under "MPEG" (Mechanical, Plumbing, Electric, and Gas) permits.
- Code Compliance: All work must comply with the building codes adopted by the county, which include the International Mechanical Code, International Fuel Gas Code, and other relevant residential and building codes.
- Submittal Process: Applications can be submitted online through the county's Evolve portal or via the official building permit application process.
- Inspections: The county conducts inspections to verify code compliance. Requests for inspections must be made to the Building Services Department, and next-day inspections must be requested no later than 3:00 PM on the preceding business day.
- Contractor Requirements: While the county manages local permits and inspections, contractors must also adhere to state-level licensing requirements governed by the South Carolina Department of Labor, Licensing and Regulation (LLR).

State Statutes and Adopted HVAC Codes
In South Carolina, building codes are mandated by the state legislature and enforced at the local level. The state utilizes the International Code Council (ICC) family of codes as the foundation for its statewide standards. As of the most recent major update effective January 1, 2023, South Carolina has adopted the 2021 editions of the International Codes, including the International Mechanical Code (IMC) and the International Residential Code (IRC), with specific South Carolina-approved modifications. These codes establish the minimum requirements for the design, installation, maintenance, and inspection of HVAC systems in residential, commercial, and industrial buildings.
Primary State Agency
The South Carolina Building Codes Council is the primary state body responsible for adopting, modifying, and overseeing the implementation of these building codes. The Council, which operates under the South Carolina Department of Labor, Licensing and Regulation (LLR), reviews ICC code editions and determines necessary state-specific amendments to address local environmental and construction conditions. While the Council sets the standards, the actual enforcement of these codes is carried out by local jurisdictions (cities and counties), which are required to employ certified building officials to conduct plan reviews and field inspections.
