Summary
Clay County adopted the 2012 International Plumbing Code as its official plumbing code under Sec. 150.17, so plumbing work in the unincorporated county runs on that code's permit and inspection rules. The county deleted the IPC's own administrative chapter and replaced it with Chapter 1 of the 2012 International Building Code, folding plumbing permits into the same building-permit process.
Sec. 150.17. - Plumbing Code. Section 1. Adoption of the 2012 International Plumbing Code (IPC).

(1)The following sections of the 2012 IPC shall be amended to read as follows:(a)Chapter 1 Scope and Administration Delete and replace with Chapter 1 of the 2012 IBC.
Full Breakdown
Sec. 17 adopts the 2012 International Plumbing Code, with three certified copies on file with the County Clerk, as the plumbing code of the county, fully effective and enforceable as amended. The only amendment listed deletes Chapter 1 (Scope and Administration) of the IPC and replaces it with Chapter 1 of the 2012 IBC, meaning the permit application, issuance and inspection procedure that governs a general building permit also governs a plumbing permit rather than a separate IPC administrative track. Because Sec. 1 of the Building Code.
The Sec. 03 appeal path applies here too: a denied plumbing permit application can be protested in writing to the Clay County Building Official within seven business days and appealed to the Clay County Building Codes Commission, subject to the county's posted appeal fee.
Violations & Fines
Plumbing work performed without the required permit falls under the same Sec. 150.04(B) misdemeanor as any other unpermitted building work, with the penalty referencing RSMo Sec. 64.200. Each ten-day period the unpermitted plumbing installation or repair remains uncorrected is charged as a separate offense, and the county retains authority to compel removal or correction of the work on top of any fine imposed.
