Summary
Plumbing work in unincorporated Grant County falls under the Uniform Plumbing Code, adopted by reference at GCC 14.04.030(d), except for the code's own sewer and fuel-gas piping provisions, which the county leaves out. A permit from Development Services is required before the work begins.
(d)Except as provided in RCW 19.27.170, the Uniform Plumbing Code and Uniform Plumbing Code Standards, published by the International Association of Plumbing and Mechanical Officials with appendices E and K: provided that any provisions of such code affecting sewers or fuel gas piping are not adopted;
Full Breakdown
030(d) adopts the Uniform Plumbing Code and Uniform Plumbing Code Standards, published by the International Association of Plumbing and Mechanical Officials with appendices E and K, as part of the Washington State Building Code package alongside the International Building, Residential, Mechanical, and Fire Codes. 170. 050: the application is deemed abandoned after 180 days without good-faith progress, the permit expires three years after issuance, and fees are set from ICC Building Valuation Data updated every July 1. 1 of the Property Maintenance Code's plumbing chapter in force, requiring fixtures to be properly connected to either a public sewer system or an approved private sewage disposal system, while the rest of that chapter's requirements are not adopted. Appeals of a plumbing permit decision go to the Grant County Hearing Examiner sitting as the Building and Fire Board of Appeals.
Violations & Fines
Plumbing work performed without a permit, or that fails to meet the adopted Uniform Plumbing Code, is enforced under the same GCC 1.32 process as other building violations: a stop-work order can halt the job, and a citation carries a $500 civil fine per occurrence, rising to $1,000 and $2,000 for repeat violations within 24 months.
