La Salle County Building & Safety Divisions
La Salle County's Land Use Department is responsible for overseeing development and construction within the county's unincorporated areas. This department issues building and construction permits and maintains records of development activities. They also manage building code inspections, which are conducted by a private firm hired by the county to ensure compliance with adopted building codes.
Effective January 1, 2025, La Salle County will adopt updated building codes, including the International Residential Code 2024, International Building Code 2024, International Fire Code 2024, International Mechanical Code 2024, International Fuel Gas Code 2024, and National Electrical Code 2023, with specific amendments.
Rules for Properties in Unincorporated Areas
Building permits are required for most construction projects in unincorporated La Salle County. This includes all commercial projects, residential structures over 200 square feet or with a side of 20 feet or greater, and residential remodeling involving structural changes. Permits are also necessary for signs, fences, pools, solar and wind equipment, and towers.
Agricultural buildings are exempt from local county building code inspections but are still subject to Illinois Department of Public Health plumbing inspections.
Construction must not begin before a building permit is issued, as doing so can result in a penalty of double the permit fee. It is recommended to apply for permits at least 30 days in advance of anticipated construction.
Specific ordinances, such as the LaSalle County Setback Ordinance and Zoning Ordinance, also apply to structures in unincorporated areas, dictating minimum distances from roadways and property lines.
Plumbing contractors must possess a state license number for registration.

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).
