Washington County Building and Safety Divisions
In Washington County, Idaho, building permits, including those for plumbing, are primarily handled by the County Planning & Zoning Department for unincorporated areas. The Idaho Division of Building Safety (DBS) may issue plumbing permits in unincorporated areas if the county does not handle them locally. However, Washington County's Planning & Zoning Department appears to manage these permits directly.

For properties in unincorporated Washington County, a building permit is required for various construction activities, including new structures, additions, alterations, demolition, moving of structures, changes in occupancy, and sewer system installations.
Specific requirements for obtaining a building permit include:
- Submitting a completed permit application.
- Providing plans and specifications that conform to County zoning and building codes.
- Including a site plan.
- Obtaining approval from the County Road Supervisor for any culvert installation or driveway approach onto county roads.

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.
