Washington County, Illinois Plumbing Permit Requirements
Washington County, Illinois, has specific requirements for plumbing permits, particularly for properties in unincorporated areas. The county's zoning ordinance mandates that all construction, including agricultural buildings, requires a building permit.
For unincorporated areas, Washington County itself issues building permits. If a property is located within an incorporated city, that city's building department is responsible for permit issuance, not the county.
While specific details on plumbing permit applications for unincorporated Washington County are not extensively detailed in the search results, general Illinois plumbing regulations and practices can provide guidance. In Illinois, plumbing permits are typically issued to Master Plumbers licensed by the State. Homeowners may be able to obtain a permit if they occupy the property, purchase their own materials, and perform the work themselves, provided it meets all code requirements.
The Illinois Plumbing Code sets the standards for plumbing work. Licensed plumbers are required to have specific state registrations and may need to provide a letter of intent with their permit applications, especially in municipalities within larger counties.
It's important to note that permit requirements can vary significantly across different jurisdictions in Illinois. Unincorporated areas in smaller, downstate counties may have minimal or no formal building code adoption.
Rules for Properties in Unincorporated Areas
Washington County issues building permits for properties located in unincorporated areas of the county. All construction within Washington County, including agricultural buildings, requires a building permit.
For areas outside of incorporated cities, the county government is the permitting authority. However, the specific details regarding plumbing permits for unincorporated areas of Washington County would need to be confirmed directly with the county's relevant department, likely the Zoning or Building Department, as detailed information was not readily available in the search results.

State Statutes and Plumbing Codes in Illinois
The state of Illinois does not adopt model codes like the International Plumbing Code (IPC) or the Uniform Plumbing Code (UPC) on a statewide basis. Instead, the state utilizes a standalone, state-developed code known as the Illinois Plumbing Code. This code is codified in the Illinois Administrative Code as Title 77, Part 890.
The authority for these regulations is established by the Illinois Plumbing License Law (225 ILCS 320), which mandates the creation of minimum standards for plumbing materials, fixtures, design, and installation methods to protect public health and safety.
Primary State Agency
The Illinois Department of Public Health (IDPH) is the primary state agency responsible for setting and maintaining these standards. The IDPH Plumbing Program oversees the licensing of plumbers and apprentice plumbers, the registration of plumbing contractors, and the enforcement of the Illinois Plumbing Code across the state, except in jurisdictions that may have their own specific building code requirements (such as the City of Chicago, which maintains its own building code).
