What the City asks for
From the City's New Residential building permit application (Form 1.2, updated 25 August 2021, read 24 October 2026), which covers detached houses, duplexes and townhomes of three stories or less with a separate exit:
| Document | The City's requirement |
|---|---|
| Site plan | Scaled, "prepared, signed and sealed by a South Carolina licensed land surveyor or design professional" |
| Building plans | Foundation, floor, elevations, electrical, windborne debris protection; building height shown from the curb or street elevation |
| Structural plans | Signed and sealed by a South Carolina licensed design professional |
| Energy | Manual J load calculation, plus the IECC contractor compliance form or a REScheck document |
| Flood | V-Zone flood design certificate and breakaway wall certificate, if applicable |
| Historic districts | If the address is under Board of Architectural Review jurisdiction, the BAR placard or approval |
| Driveway | An Engineering (right-of-way) permit for new driveway aprons and sidewalks in the right of way |
Who can apply
Contractors fill in an SC LLR license number and a City of Charleston business license number. The form also has a section "for property owners as applicants only", which says "when the total value of construction is over $5,000, property owners must file the exemption form", with the appropriate county office, before the permit can be issued.
Inspections
The form lists the inspections a new house goes through: footing, rebar and block; foundation wall; slab; pile or pier; bond beam; sheathing; strapping and tie-down; framing and hold-down; electrical, mechanical, plumbing and fuel gas rough-ins; and building and trade finals. On top of those, "a Final Engineering Site Inspection is required for all new single-family construction", as is a water and sanitary utility inspection or approval, and an elevation certificate in a flood zone.
The form lists no fees; ask the Department of Permitting & Inspections for the amount, which is worked from the valuation.

The middle half of houses reached final between 170 and 287 days after issue, so plan on six to nine months of build time once the permit is in hand.

Before you hire
Check the builder's South Carolina license on the SC LLR license lookup, and the permits already on the lot with the Charleston, SC building permit search guide. What other places ask for is in do I need a permit to build a house; filed values elsewhere in new home construction cost.
What this does not tell you
The City's public layer holds building permits only and names no builder, so the electrical, plumbing and mechanical permits on each house are missing and we do not rank firms. The valuation is the figure on the application, not the build or sale price. North Charleston, Mount Pleasant, Summerville and unincorporated Charleston County issue their own permits and are not counted.
