Washington, Benton County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas
Benton County, Washington Plumbing Permit Requirements
Benton County, Washington, has specific requirements for plumbing permits, particularly for properties located in unincorporated areas. The county's Building and Safety Division oversees these regulations.
Jurisdiction and Unincorporated Areas
Benton County is responsible for issuing building permits for properties situated in unincorporated areas of the county. If a property is within an incorporated city, that city's building department will handle permit applications, not the county.
General Plumbing Permit Requirements
- Permits are generally required for all new plumbing work.
- Permits are typically issued only to the individual or contractor performing the work.
- Permits expire if work is not commenced within 180 days of issuance or if work is suspended for 180 days.
- Contractors must possess a valid and current contractor's license.
- For certain types of work, such as new plumbing, a water utility provider and a plumber's license are required.
Exemptions
While permits are generally required for new plumbing work, some exemptions may apply. For instance, detached accessory structures like tool sheds or carports that do not exceed 200 square feet may be exempt from building permits. However, permits will still be required for new plumbing, electrical, or HVAC work, even for these structures.
Additionally, installations on residential or farm property owned by the applicant or an immediate family member may be exempt from licensing requirements under specific state regulations.
Permit Application Process
The application process typically involves submitting a completed application form, which may include details about the job site, applicant information, property owner information, and a description of the work to be performed.
Fees for plumbing permits are based on the type of installation and equipment value. A fee schedule outlines costs for various scenarios, such as new residential installations with a specified number of bathrooms and kitchens, or remodel/alteration work.

The following statewide building codes and regulations apply universally to all jurisdictions within Washington:
Washington Plumbing Legislation, Codes, and Guidelines
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.
