Full Breakdown
Section 15.12.010 adopts the 2017 Idaho State Plumbing Code (ISPC), including appendices A, B, D, E, G, H, I, J, K and L, as adopted by the State of Idaho at IDAPA 07, title 02, chapter 06. The City Council makes six changes. ISPC section 104.5 is deleted. ISPC section 1002.3 is replaced so that for trap arms two (2) inches in diameter and larger, the change in direction shall not exceed one hundred eighty (180) degrees without the use of a cleanout. IDAPA 24.39.20.08 is not adopted, which reinstates the shower pan test per ISPC 408.7.5. IDAPA 24.39.20.14.a is not adopted, which reinstates freeze resistant yard hydrant backflow. IDAPA 24.39.20.26 is not adopted and ISPC 610.2 is adopted. ISPC Combined Systems section 1101.12.2.2.2 is deleted. Any city provision more restrictive than the state code takes precedence.
The residential building code does not cover this work: Section 15.08.005 states that Part VII Plumbing and Part VIII Electrical of the International Residential Code are not adopted.
Registration sits in Section 15.12.020. It is unlawful to work as a drain layer without registering with the City, registration expires December 31 each year, and a full year's fee is collected regardless of the date. Plumbing contractors, journeyman plumbers, apprentices and the specialty mobile home trades need a certificate of competency under chapter 26, title 54, Idaho Code, but drain layers and homeowners doing work in their own homes need no state certificate. A drain layer contractor must file a bond in the sum of $2,000 (Section 15.12.030), and no permit is granted to one until registered (Section 15.12.040).
Inspection runs through the State. Section 15.12.070 authorizes the Mayor, with City Council approval, to contract with the Idaho State Plumbing Board for a state plumbing inspector to act as the City's inspector, and Section 15.12.080 makes plumbing installed in any building or structure in the City subject to that inspection.
Violations & Fines
Working as a drain layer or plumbing trade person without the required registration or certificate is unlawful under 15.12.020. Section 1.28.010 makes an ordinance violation a misdemeanor unless an infraction penalty applies, with a fine of not more than $1,000, imprisonment not to exceed 180 days, or both. An infraction is $100, and each day a violation continues is a separate offense.
