Jurisdictional status
Municipal Fallback
This profile identifies a handoff outside the county’s ordinary structural permitting lane.
Required jurisdiction check
Confirm the controlling local or state authority before filing.

Project questions
Frequently asked questions for Williamsburg 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 843-355-9321 ext. 5300; Deputy Code Enforcer/Building Inspector ext. 5303.
How long might review take?
N/A for ordinary building permits; a 2024 county solar-facility ordinance requires complete solar site-plan review within 45 days, but that timeline does not apply generally to building permits.
How are inspections scheduled?
Call 843-355-9321 (ext. 5300 or inspector ext. 5303) with the address, tax map or permit number, inspection type, contractor name and contact phone. Williamsburg County requires at least 48 hours' notice and cannot guarantee a specific time, only before or after lunch. Approved plans must remain on site and the permit must be posted. Residential sequence includes foundation, slab, piers/CMU where applicable, wall/roof sheathing, rough-in, framing, insulation, temporary power and final inspection.
Which codes and exemptions should I review?
Williamsburg County's 2022-08 amended building/fire-code ordinance and plan guidance require the current South Carolina code cycle. For 2026 this is the 2021 International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes with South Carolina modifications, the 2020 National Electrical Code, the applicable energy code and ICC A117.1 accessibility standard. N/A; the reviewed current county permit pages do not publish a consolidated minor/cosmetic exemption list. Farm structures may use the South Carolina farm-structure affidavit process, while the county requires applicants to confirm other exemptions with Code Enforcement before work begins.
