Clallam County Plumbing Permit Requirements
Clallam County's Department of Community Development, specifically the Building Division, handles permit requirements for construction and modifications, including plumbing work. This jurisdiction applies to properties within unincorporated areas of the county.
A building permit is generally required for any work that erects, constructs, enlarges, alters, repairs, moves, improves, converts, or demolishes a building or structure. This explicitly includes plumbing modifications. While some minor construction activities may be exempt based on valuation, plumbing work is often excluded from these exemptions and may still require a separate permit even if the overall project is exempt. For instance, work exempt under IRC Section 105.2(1) for detached accessory buildings under 400 square feet does not exempt associated electrical, plumbing, or mechanical activities.
Plumbing Inspection Specifics:
- Plumbing inspections should be requested before the framing inspection or concurrently with it.
- All drainage, waste, and vent pipes require a water or air test (plastic pipe cannot be tested with air). This test must remain in place until the inspection is complete.
- Water lines are tested using existing water pressure or a 50 psi air test with a gauge.
- Shower pans must be inspected after being filled with water and before tile work begins.
- Fire sprinkler system piping, if applicable, will be inspected under a separate permit.
General Permit Information:
- Permit fees are determined by project valuation and type, with plumbing permits typically ranging from $100 to $900. The minimum permit fee is $50.
- Plan review fees are generally 65% of the building permit fee and are paid at the time of plan submittal. An alternative administrative fee of 35% may apply for private plan reviews.
- All building applications must be submitted online through the Clallam County Permit Portal.
- Inspection requests must be received by 7:30 AM on the day of the inspection.
- For final inspections, coordination with the Environmental Health Department (for septic approval) and Public Works Department (for drainage approval) is necessary.

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.
