Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; the county publishes required plan and septic documentation but no standard permit-review timeline.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 864-424-2341 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 864-424-2341.
N/A; the county publishes required plan and septic documentation but no standard permit-review timeline.
A 24-hour notice is required for all inspections; contact the Building Safety office at 864-424-2341. Post and protect the permit and address at the site. Required residential stages include footing, foundation, under-slab plumbing, slab, rough plumbing/electrical/mechanical, fireplace where applicable, framing, insulation, power/meter release, final trade inspections and final building. A certificate of occupancy is issued after final building approval.
Union County and its municipal partners adopt the latest International Building Codes; the county's 2024 hazard-mitigation plan identifies the 2021 code adoption context. The applicable 2026 South Carolina cycle is the 2021 International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes with South Carolina modifications, 2020 NEC and applicable state energy/accessibility requirements. The county lists retaining walls no higher than 4 feet; sidewalks and driveways no more than 30 inches above grade; painting, papering, tiling, carpeting, cabinets, countertops and similar finish work; qualifying above-ground pools less than 24 inches deep and not over 5,000 gallons; fences; minor electrical repairs such as replacing lamps or defective receptacles; portable heating appliances or replacement parts that do not alter equipment approval; and plumbing repairs such as leaks, drain/waste/vent repairs and stoppage clearing.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
