Custer County, Idaho Plumbing Permit Requirements
In Custer County, Idaho, plumbing permit requirements for properties in unincorporated areas are managed by the Custer County Planning & Zoning Department. While the county issues a "building notification," separate electrical, plumbing, and HVAC permits may be required from the Idaho Division of Building Safety. It is crucial to contact the Planning & Zoning Department for specific guidance, as they review projects for zoning compliance and floodplain status before issuing a building notification. For any plumbing work, it is generally necessary to obtain a permit from the Idaho Division of Occupational and Professional Licenses (DOPL), unless an exception applies. Licensed plumbers are required to perform plumbing work, and permits are typically issued only to individuals or entities holding a valid certificate of competency.
For new residential construction, additions, major renovations, and commercial or industrial buildings in unincorporated areas, a building notification is required. This process involves obtaining a zoning compliance certificate and, if applicable, an approved septic permit from Eastern Idaho Public Health. The building notification application must include all required documents, such as a site plan, proof of ownership, and the approved septic permit.
Specific plumbing permit applications can be found on the Idaho Division of Occupational and Professional Licenses (DOPL) website, which includes applications for both contractor and homeowner plumbing permits. Permit fees are generally non-refundable.

State-Level Plumbing Codes and Legislation in Idaho
Plumbing regulations in Idaho are established to protect public health, safety, and welfare by setting minimum standards for the design, installation, and maintenance of plumbing systems. The legal framework for these regulations is primarily found in Idaho Code Title 54, Chapter 26, which governs the licensing of plumbing professionals and the administration of the state's plumbing program.
The state of Idaho adopts the Uniform Plumbing Code (UPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO), as its base technical standard. This is integrated into the Idaho State Plumbing Code (ISPC), which includes the base UPC along with specific state-level amendments adopted by the Idaho Plumbing Board to address local conditions and requirements. These rules are further detailed in the Idaho Administrative Code (IDAPA), specifically under the rules governing plumbing.
Regulatory Agencies and Oversight
The primary state agency responsible for the administration and enforcement of plumbing standards in Idaho is the Division of Occupational and Professional Licenses (DOPL). DOPL oversees the licensing of plumbing contractors, journeyman plumbers, and apprentice plumbers, as well as the issuance of permits and the conduct of inspections.
Within this structure, the Idaho Plumbing Board plays a critical role. The Board is responsible for adopting and updating the Idaho State Plumbing Code, reviewing licensing applications, and addressing industry concerns. The Board works in conjunction with DOPL to ensure that plumbing installations across the state comply with established safety and technical standards.
