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).
