Full Breakdown
City Code Section 7-26(a) adopts the latest South Carolina Residential Code and South Carolina Building Code, as published by the International Code Council, and requires that all building construction, reconstruction, alteration and repair, including plumbing systems and appliances, conform to those codes. C. Code Section 6-9-60. 1 to set a minimum burial depth of 12 inches for water service piping exposed to freezing, twice the model code's usual cover requirement. Because the state code is incorporated by reference rather than rewritten locally, plumbing work triggers the same permitting and plan-review steps built into that code; the Building Inspections Division within the Department of Public Service reviews plans and issues plumbing trade permits alongside building, electrical, fuel gas and mechanical permits.
City Code Section 2-274 lets the city waive permitting fees, including trade permits for plumbing, on city-owned construction projects and priority-status affordable housing projects, but fines and fees for starting work without a permit are excluded from any waiver. Charleston does not maintain a standalone local plumbing chapter; the plumbing rules that apply inside the city are the adopted state code plus these Section 7-27 amendments.
Violations & Fines
Charleston's adopted Building and Residential Codes carry their own stop-work and revocation powers for work performed without a permit; where a specific fine is not set for a violation, City Code Section 1-16's general penalty applies, up to a $500 fine or 30 days in jail, with each day the violation continues counted as a separate offense.
