Washington County, Tennessee Plumbing Permit Requirements

Washington County, Tennessee, has adopted the 2018 International Residential Code (IRC) for building and safety regulations. This code sets minimum standards for public safety, health, and welfare, covering aspects like structural strength, sanitation, and fire safety. The county's Zoning Office is responsible for regulating development in the rural, unincorporated areas, including building codes, planning, and stormwater management.

For properties in unincorporated areas, Washington County issues building permits. If your property is within an incorporated city, that city's building department will handle your permits.

While the search results detail building permit requirements and the adoption of the International Residential Code, specific plumbing permit requirements are not explicitly detailed. However, Tennessee has state-level plumbing regulations. The state adopts the International Plumbing Code (IPC) as its baseline, which governs materials, installation standards, fixture requirements, and system design. Local jurisdictions, including counties, may adopt amendments to the state-adopted IPC.

The Washington County Zoning, Planning & Building Codes department handles building permits and inspections. Rough-in plumbing and final plumbing inspections are listed as part of the inspection process.

For specific plumbing permit applications and detailed requirements, it is recommended to contact the Washington County Zoning, Planning & Building Codes department directly. The county's website provides forms for residential building permits and zoning compliance applications.
