Okanogan County Building & Safety Division and Unincorporated Area Regulations
Okanogan County's Building Department is responsible for issuing permits and enforcing building codes, including those for plumbing, in both incorporated and unincorporated areas. The county has adopted various building and related codes, including the International Residential Code and the Uniform Plumbing Code, as amended by the Washington State Building Code Council.
For properties in unincorporated areas, standard county-level building permit requirements apply. This means that any construction, alteration, repair, or installation of plumbing systems that is regulated by the adopted codes will require a permit.
Key requirements and procedures include:
- Permit Application: An application must be submitted to the Building Official to obtain the required permit before commencing work.
- Plan Review: Two sets of complete plans typically accompany the permit application. A plan review fee is often required at the time of application.
- Departmental Approvals: Before a permit can be issued, applicants may need to obtain approval from other county departments, such as Planning and Public Health (for septic and water adequacy, if required).
- Plumbing Certification: A "Plumbing & Gas Piping Certification Pressure Test" form is used by the Okanogan County Building Department, indicating specific testing requirements and certifications are necessary.
- Inspections: The owner or contractor is responsible for scheduling required inspections at various stages of the project. Approved plans and the permit must be on-site for inspections to be completed.
- Permit Validity: Permit applications generally remain valid for one year from the date received and may require extensions if the project is not completed within specified timeframes.
- Code Adoption: Okanogan County has adopted the 2021 International Codes, with a revised effective date of March 15, 2024. Fees have also been updated.

Plumbing Codes and Legislation in Washington State
The state of Washington regulates plumbing systems through the adoption of the 2021 Uniform Plumbing Code (UPC), which is published by the International Association of Plumbing and Mechanical Officials (IAPMO). This model code is adopted by reference and modified by state-specific amendments to create the Washington State Plumbing Code, codified under Chapter 51-56 of the Washington Administrative Code (WAC). These regulations are established under the authority of the Revised Code of Washington (RCW) Chapter 19.27, which governs the State Building Code.
Primary State Agencies
Two primary state entities oversee the plumbing regulatory framework in Washington:
- Washington State Building Code Council (SBCC): This council is responsible for the adoption, maintenance, and amendment of the state building codes, including the Washington State Plumbing Code. They regularly review and update these codes to ensure they remain consistent with state safety and health standards.
- Washington State Department of Labor & Industries (L&I): This department is the primary authority for the administration of plumber certification, plumbing contractor licensing, and enforcement of professional standards. While the SBCC sets the technical code, L&I manages the workforce and business regulations associated with the plumbing trade, as outlined in RCW Chapter 18.106 and WAC Chapter 296-400A.
It is important to note that while the state sets the minimum standards, local jurisdictions (cities and counties) are responsible for issuing permits and conducting inspections. Local authorities may also adopt additional, stricter amendments to the state code.
