Required jurisdiction check
Confirm the controlling local or state authority before filing.

Project questions
Frequently asked questions for Dorchester County
Who handles permitting for this jurisdiction?
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 843-832-0011.
How long might review take?
N/A for plan review; next-day inspection requests are available when submitted by 3:00 p.m. the prior business day.
How are inspections scheduled?
Request inspections by calling 843-832-0011 or emailing InspectionRequests@DorchesterCountySC.gov. Next-day inspections must be requested no later than 3:00 p.m. on the preceding business day. Keep the county-approved stamped construction documents and engineered-product shop drawings at the job site for each inspection.
Which codes and exemptions should I review?
Dorchester County lists the 2021 International Building, Fire, Plumbing, Mechanical, Fuel Gas, Residential, and Existing Building Codes; 2020 National Electrical Code; and 2009 International Energy Conservation Code. The listed codes took effect January 1, 2023, except the energy code, which is listed as effective January 1, 2016, and include South Carolina's mandatory modifications. Dorchester County states that detached accessory structures under 200 square feet that are not intended for living purposes are exempt under the South Carolina Residential Code. Adding living amenities changes the structure's intent and removes that exemption. The department does not publish a complete separate list of cosmetic or ordinary-repair exemptions; confirm all other work with Building Services.
