Full Breakdown

001(B) of the Mount Pleasant Code adopts the International Plumbing Code, as amended by the South Carolina Building Codes Council, by reference as though fully set forth in the town's own code, alongside the Building, Mechanical, Fuel Gas, Residential and other International codes listed in the same section. 003. 002: the Building Official values the work using ICC Building Valuation Tables or the contract amount, whichever is higher, and all building permits, including plumbing, are value-based. No permit is required where the materials-and-labor valuation does not exceed $1,000, unless an inspection is required regardless of value.

Work started before a permit is obtained still triggers a fee under the Department of Engineering and Development Services' latest fee schedule, but paying it does not excuse full code compliance or other penalties. 019. 999, the chapter's catch-all penalty.
