Deck Construction Permits in Columbia

Local Rule

City of Columbia Development Services, Richland County Building Inspections

Columbia enforces the statewide South Carolina exemption of 200 square feet, 30 inches above grade, not attached to the dwelling and not serving a required exit door. The city's own fee schedule, effective September 2025, sets a $5 minimum zoning permit fee for single-family residential projects and a $50 minimum for commercial building permits, with a 30 percent surcharge on the building permit fee if a submittal needs a third plan review round. South Carolina law separately exempts any construction in a city over 97,000 residents, which includes Columbia, from needing a permit at all when total materials and labor valuation stays under $1,000, and charges only a flat $2 fee for valuations between $1,000 and $2,500, though most deck projects exceed that threshold in practice.

How This Compares to Richland County

Columbia's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:

Richland County Building Inspections

A deck under 200 sq ft, under 30 inches above grade, freestanding and not serving an exit door is exempt from a building permit; otherwise Richland County Building Inspections issues the permit. Distinctively, once the contract value of the deck work exceeds $5,000, South Carolina law requires the work to be pulled by a licensed residential builder rather than an unlicensed owner-builder.
