Columbia, SC
Columbia Plumbing Permit Cost
A standalone Columbia plumbing permit prices at $20.00 up to $5,000 of value then $4.00 per $1,000 or fraction thereof for one- and two-family residential
and the $50.00 + $9.00-per-$1,000 commercial ladder for commercial work — with the City's no-cost rule for subcontractors filing under the general contractor's permit number.

Fees that do not apply here
Listed so you can see what was considered and left out, rather than wondering whether something is missing. A rule can also be left out because it is not published for this permit at all, and that is stated where it matters.
- Commercial plumbing permit ($50.00 + $9.00 per $1,000 to $100,000) — This fee does not apply to the inputs provided.
- No-cost trade permit under a GC building permit — This fee does not apply to the inputs provided.
Assumptions
- Calculated from 1 fee rule in effect on 2026-09-28.
- Amounts are rounded to the nearest cent, once, at the end of each component.
Above the first $5,000 there is $7,500 of value, which rounds up to eight whole $1,000 steps: 8 × $4.00 = $32.00, plus the $20.00 base = $52.00.
What is different in Columbia
Plumbing trade permits file with the SC-licensed plumbing contractor's information, the total contract value and the master permit number where applicable. The Development Center reviews the work concurrently with zoning, and inspections run at rough-in and final through the Access portal. Columbia's flat residential trade rate keeps most service jobs inexpensive — a $5,000-or-less job pays the $20.00 base alone.
What this figure does not include
Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.
Not included in these figures
City of Columbia Water Works water and sewer tap and capacity fees, grease-trap review for food service, backflow device registration, and re-inspection charges are outside the trade permit fee.
What you need before applying
- South Carolina Plumbing Contractor LicenseRequired
Plumbing trade permits are issued to SC-licensed plumbing contractors; subcontractors under a general contractor file with the GC's permit number for a no-cost permit.
