Cook County Plumbing Permit Requirements
In Cook County, Illinois, plumbing permits are required for most plumbing work, including installation, alteration, or repair of plumbing systems, sewer lines, water lines, septic systems, wells, lawn sprinklers, and gas piping. This applies to both new construction and renovations, with the exception of "ordinary repairs" that do not involve structural changes or affect safety features.
For properties in unincorporated areas of Cook County, the County's Department of Building and Zoning handles permit applications.
County-Level Jurisdiction and Divisions
Cook County's Department of Building and Zoning oversees building and safety regulations, including plumbing permits, for unincorporated areas. The department has specific divisions and processes for various types of permits, including plumbing.
Rules for Properties in Unincorporated Areas
Properties located in unincorporated areas of Cook County fall under the jurisdiction of the Cook County Department of Building and Zoning for permit requirements. This means that any significant plumbing work, beyond ordinary repairs, will require a permit obtained through the county.
Contractors performing work in unincorporated Cook County are generally required to register with the Department of Building and Zoning. Permit applications can often be submitted digitally, with specific requirements for documents such as a plat of survey, scope of work, and letters of intent from contractors.
Plumbing permits are typically valid for 12 months from the date of issuance, with the possibility of a six-month extension under certain conditions.

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).
