Jefferson County, Illinois Plumbing Permit Requirements

Jefferson County, Illinois, does not appear to have a readily available, dedicated "Building & Safety Division" page on its official county website that specifically details plumbing permit requirements for unincorporated areas. However, general building permit information and contact details for the county are available.

For properties in unincorporated areas of Jefferson County, it is crucial to contact the county directly to ascertain the specific plumbing permit requirements. The county courthouse is located at 100 South 10th Street, Mt. Vernon, IL 62864, and can be reached by phone at (618) 244-8000.

While a specific county building code is not explicitly published online, state law mandates that statewide minimum standards apply if a county does not adopt its own local code.

The Illinois Plumbing License Law requires that all plumbing inspectors, regardless of whether they are employed at the state, county, or municipal level, must be licensed under the law.

For specific projects, such as those involving plumbing not connected to a municipal sewer system, a Septic Permit or Approval Letter from the Jefferson County Health Department may be required.

The City of Mt. Vernon, which is within Jefferson County, has its own building permit process. Their Engineering and Inspections Office can be reached at (618) 242-6830.

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).
