Building permits in unincorporated York County — the fast-growing Charlotte-metro county on the Lake Wylie side of the state line — are issued by the Planning and Development Services Department, with applications filed through the County's online permitting system. Plan review runs in parallel across building, MEP, zoning, and stormwater.
This York County building permit guide covers what requires a permit, how fees work, the online portal process, trade permits, and inspections — so your York County project starts clean.
York County issues building permits for unincorporated areas, plus the Town of Hickory Grove and Town of Sharon. Fort Mill, Tega Cay, Rock Hill, York, and Clover issue their own permits inside city limits (though the County still routes well and septic approvals through SC DHEC). Use the County GIS to confirm which jurisdiction your parcel is in.
What requires a building permit in York County?
Under the South Carolina building codes (the International Codes as adopted with South Carolina modifications by the South Carolina Building Codes Council, then locally administered and enforced), a permit is required before you construct, enlarge, alter, repair, move, demolish, or change the occupancy of most structures and systems. Common triggers include:
Permit required
- New construction, additions, and renovations
- Structural / load-bearing alterations and demolition
- Reroofing, windows, doors, and exterior changes
- Electrical service changes and most wiring alterations
- Mechanical / HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Decks, pools, accessory structures, and signs
- Change of occupancy or use
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- Like-for-like fixture/device swaps by a licensed contractor
- Routine maintenance not altering structure or systems
- Small projects expressly exempt by code (confirm first)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. A new single-family home triggers a stack of permits, not just one — plan for building plus trades.
Who handles permitting in York County?
The Planning and Development Services Department oversees building, planning/zoning, subdivision, floodplain, and stormwater for unincorporated York County, issuing building and land-disturbance permits. The Development Services Center is the primary contact point, and review runs in parallel across building, electrical, plumbing, mechanical, zoning, stormwater, and resource conservation.

York County building permit cost
York County calculates building permit fees on a square-foot basis using the South Carolina ICC valuation table, then layers in plan review fees, trade permit minimums, and impact fees that vary by school district.
A clean first submittal typically clears review in about two to four weeks. Confirm current amounts before budgeting.
| Fee component | How it works |
|---|---|
| Building permit fee | Square-foot basis (SC ICC valuation table) |
| Plan review fee | Layered on building permit |
| Trade permits (E / P / M) | Charged separately (minimums apply) |
| Impact fees | Vary by school district |
| Well / septic | Routed to SC DHEC |
| Work-without-permit | Penalties and possible stop-work orders |

York County trade permits
Electrical, plumbing, and mechanical work needs its own permit and a South Carolina-licensed contractor, filed through the online portal; trade minimums apply.
Electrical permits
Required for service upgrades, panels, solar PV, and most wiring, performed by a SC-licensed electrical contractor.
Plumbing permits
Required for new plumbing, repipes, water heaters, fixtures, and gas piping, performed by a SC-licensed plumbing contractor.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration, performed by a SC-licensed mechanical contractor. Specialized systems are permitted and inspected separately.
Miscellaneous & specialty
Reroofs, decks, pools, accessory structures, and signs are permitted separately. Well and septic approvals are routed to SC DHEC through county applications, and land-disturbance work follows the County's stormwater and sediment-control ordinances.
Verify your contractor's license. South Carolina licenses commercial general and mechanical contractors through the SC Contractor's Licensing Board, and residential builders, residential specialty contractors, and home inspectors through the SC Residential Builders Commission — both under the SC Department of Labor, Licensing and Regulation (LLR). A license is generally required once the value of the work exceeds $5,000 (S.C. Code 40-11-260 for commercial/mechanical; the Residential Home Builders Act for residential). Verify before signing; the property owner is responsible for ensuring a permit is obtained.

Inspections in York County
