County and city pages for South Carolina
From the nationwide permit finder; counties and cities issue most land-use approvals, so start with the jurisdiction that covers the parcel.
- South Carolina — Water permitting programs (State): South Carolina environmental authority. Start with this agency for the linked water program. Check construction stormwater, wastewater and water-quality approvals separately; this link does not cover every environmental permit.

Locate the relevant government using this directory; some directories list only cities or only counties. Confirm municipal boundaries and any separate fire, drainage, water or other district authority.
