South Carolina permit-fee context
Charleston + Greenville mid-tier; coastal counties add storm-zone inspection fees.
Why deck? Single building permit; modest valuation. Higher if >30in above grade (most). Coastal/freeze zones add structural review.
What this fee does NOT include
- Plan-review service fees (typically 0.5–1% of cost, separate line)
- Per-trade fees (plumbing, electrical, mechanical — $50–$200 each)
- State-level surcharges (FL DBPR, NJ DCA, OR BCD, etc.)
- Contractor's filing/processing fee
Rule of thumb: budget 1.5–2× the base permit fee for the all-in cost.

FAQ — Deck permits in South Carolina
How much is a deck permit in South Carolina in 2026?
On a typical $9,000 deck project in South Carolina, the statewide median permit fee runs $89 — about 0.99% of project cost. Major metros run higher: Charleston $111, Greenville $102, Columbia $94. Charleston + Greenville mid-tier; coastal counties add storm-zone inspection fees.
Why is the fee higher in major South Carolina metros?
Each South Carolina city/county sets its own multiplier on top of the state base rate. Charleston runs 1.25× because of stricter plan review + structural review + energy-code overhead. Columbia sits lower (1.05×) because of less plan-review depth + simpler intake. Rural counties in South Carolina often have flat-fee schedules below even the lowest metro.
What's included in the permit fee vs. what's billed separately?
The permit fee covers the building department's intake + base review. NOT included: plan-review service fees (often a separate line, 0.5–1% of project cost), per-trade fees for plumbing/electrical/mechanical (typically $50–$200 each), and any state-level surcharges (FL adds DBPR 1.5%, NJ adds DCA, OR adds 12% BCD surcharge). Your contractor's filing fee is also separate. Budget 1.5–2× the base permit fee for the all-in cost.
Can I skip the permit and save the fee?
Don't. Working without a required permit fails any future resale inspection (the buyer's inspector WILL flag it), voids your homeowner's insurance for any related claim, and triggers retro-permitting fines that are typically 2–3× the original fee. South Carolina treats unpermitted deck work as a separate violation under state building code. The "savings" become a $1,500 problem at resale on a $500 fee.
