Skagit County Plumbing Permit Requirements
Skagit County's Planning and Development Services, specifically the Building Division, oversees the enforcement and administration of building construction codes and ordinances to ensure safety in unincorporated areas. Plumbing permits are generally required for new installations, water heater replacements, relocating water or drain lines, converting tubs to showers, and installing or replacing backflow prevention devices. Minor repairs, such as fixing a faucet or unclogging a drain, typically do not require a permit.
For properties in unincorporated areas, Skagit County requires permits for most construction, alteration, repair, or demolition of buildings and structures, including plumbing work. While some small detached buildings (under 200 sq ft) may be exempt from a building permit, they still require approval if they contain plumbing. Additionally, mechanical work, even if exempt from a building permit, may require a separate mechanical permit. Electrical work may also require permits from the Washington State Department of Labor and Industries.
When applying for permits, whether as a homeowner or a contractor, you will need to provide details about the scope of work and property information. Licensed plumbers are expected to obtain the necessary permits and coordinate inspections. If you are undertaking the work yourself (DIY), you are responsible for applying for the permit and scheduling inspections.

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.
