Adams County Building & Safety Division and Unincorporated Areas
Adams County, Idaho, requires building permits for all construction within its unincorporated areas. The county enforces building codes based on the 2021 International Building Code (IBC) and the 2018 International Residential Code (IRC), with amendments from Idaho. While the county has a Building Department, specific details regarding a dedicated "Building & Safety Division" for plumbing permits are not explicitly detailed, but the Building Department handles permit applications and plan reviews.
Plumbing permit requirements are generally managed through the county's building permit process. This includes submitting detailed construction documents, site plans, and potentially engineering calculations. The county's Building Department is the primary point of contact for obtaining applications and information regarding permit fees.
For properties in unincorporated areas, the standard county building permit process applies. This means that any new plumbing installations or significant modifications will likely require a permit obtained from the Adams County Building Department.

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.
