Charleston Permits and Local Rules

Grand Trees (24 inches or more DBH, excluding pines and sweet gums) are protected in the City of Charleston, and land disturbance, fill or vehicles are not allowed inside a fenced protective zone around them during construction.

RuleWhat it means for your projectSource
Grand Tree and Protected Tree removalGrand Trees are 24 inches or more DBH (pines and sweet gums excluded) and Protected Trees are 8 inches or more DBH. On single-family or duplex residential lots, trees under 24 inches DBH need no removal permit; commercial lots, lots with three or more units and residential lots of one acre or more must keep at least 15 Protected Trees per acre. The Zoning Administrator issues removal permits after an inspection, mainly for hazardous, diseased or damaging trees.Source
Grand Tree protective zone during constructionA protective zone around Grand Trees must be kept free of land disturbance, paving, materials, fill, debris and vehicles and fenced with a barrier at least 4 feet tall. The minimum radius is 12 feet for a 24-inch tree plus 1 foot for each 3 inches over 24 inches.Source
Critical line (OCRM) bufferTrees in the critical line buffer cannot be removed; removals there are governed by Sections 54-347.1 and 54-348 of the City Zoning Ordinance. On Daniel Island, removing trees 8 inches DBH or larger in the Visual Buffer Zone needs Board of Zoning Appeals–Site Design approval.Source
City stormwater review for land disturbance (Type I)Under the City’s Stormwater Design Standards Manual, construction, development or redevelopment disturbing 0.5 to 1 acre must file a Type I application with an erosion and sediment control sketch. The plan review fee is $500 plus $200 per disturbed acre (capped at $5,000), and the City may instead require a Type II or III application.Source
Floodplain developmentA building permit is required for all development in the Special Flood Hazard Area, and fill of one foot or more along property boundaries triggers buffer requirements. In parts of the Church Creek basin, fill needs 1.25:1 compensatory storage, and encroachments in the Church Creek AE zone require an engineer’s certification that they will not raise base flood levels more than one foot.Source
Call 811 before diggingState law requires a locate request to SC811 before any excavation begins. For a normal request, operators have three full working days to mark their lines (working days exclude the day you submit, weekends and holidays); you may dig the next working day once Positive Response shows all locates are complete. A normal ticket is valid for 15 working days. Underwater excavation needs at least 10 working days’ notice and large projects at least 30 days. Private lines are the owner’s responsibility to have marked. SC811 reports that a new state law (HB 3571) took effect May 22, 2026.Source
Construction stormwater permitThe SC Department of Environmental Services (SCDES), under EPA delegation, issues coverage under the NPDES Construction General Permit SCR100000. Coverage is required for projects that disturb more than one acre, or that are part of a larger common plan that disturbs one acre or more. Sites within one-half mile of a coastal receiving water body must also apply. The re-issued permit takes effect March 30, 2026 and expires March 30, 2031.Source
Burning cleared brushSCDES Regulation 61-62.2 prohibits open burning except as listed. Burning land-clearing debris (outside predominantly residential areas) is allowed only if: the burn is at least 1,000 feet from public roadways and far enough from neighboring homes and businesses; the wind blows smoke away from roads and occupied sites; only plant material generated on site is burned, with salvageable timber and pulpwood removed first; burning starts between 9 a.m. and 3 p.m. with no material added between 3 p.m. and 9 a.m.; and no more than two 30-by-30-foot piles burn within a six-acre area at once. Local ordinances still apply. Separately, S.C. Code 48-35-10 requires notifying the State Forester before outdoor burning of woods, brush or debris; that chapter does not apply inside town or city limits (48-35-30) and bars burning during a declared forest fire emergency (scstatehouse.gov/code/t48c035.php).Source

How to Choose an Excavation Contractor in Charleston

Send every bidder the same plans and dimensions. Ask whether the price is per cubic yard, per hour or a fixed total; whether spoil haul-off, imported fill, rock and compaction testing are included; who handles permits and utility locates; and what the finished grade will look like.

For background before you call, read site preparation, excavation cost and land grading. If the site still has trees and brush, start with Charleston land clearing contractors.

What’s the difference between excavation and land grading?

Excavation digs out or moves earth to reach required depths. Land grading shapes the surface to set slope and drainage. Many sitework contractors do both, but quotes often price them separately.

How are excavation contractors priced?

By the cubic yard, by the machine-hour or as a fixed total. HomeGuide lists $2.50 to $15 per cubic yard for soil and $100 to $300 per hour for an excavator with an operator. Ask which unit a quote uses before comparing bids.
