LaSalle County Plumbing Permit Requirements
LaSalle County's Land Use Department is responsible for overseeing development and construction in unincorporated areas, including the issuance of building and construction permits. Plumbing permits are generally required for most plumbing work, with exceptions for minor repairs and fixture replacements.
County Jurisdiction and Unincorporated Areas
For properties in unincorporated areas of LaSalle County, the Land Use Department handles the permitting process. Building permits are required for various projects, including residential structures over 200 square feet or with a side of 20 feet or greater, commercial projects, and significant remodeling. Agricultural buildings are exempt from local county building code inspections but are still subject to Illinois Department of Public Health plumbing inspections.
Permit Application Process
- Confirm that your work is in unincorporated LaSalle County and is not exempt from permit requirements.
- Assemble the necessary application packet, which may include a site diagram, construction documents, and any required health department approvals (e.g., for well and septic systems).
- Submit the application to the Land Use Department at least 30 days before anticipated construction.
- The county will review the plans, and an inspector will notify the applicant when the permit is ready for pickup and provide the associated fee.
- Pay the permit fee to the LaSalle County Treasurer to receive the issued permit.
Construction beginning before a permit is issued may result in double the permit fee.

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).
