Sangamon County Plumbing Permit Requirements
Sangamon County's Building and Safety Section is responsible for enforcing construction codes, including those for plumbing systems. They review plans, issue permits, and conduct inspections to ensure compliance with life-safety, structural integrity, and accessibility standards. The county has adopted the Amended 2014 IDPH Plumbing Code. For specific questions regarding construction and building permits, you can contact a building inspector at (217) 753-6760.
For properties in unincorporated areas, Sangamon County generally handles permitting and inspections. However, if your property is within a municipality that has an Intergovernmental Agreement (IGA) with Sangamon County for building services, you may need to coordinate with that specific municipality for zoning requirements before applying for a permit with Sangamon County. Some municipalities have IGAs for commercial projects only.
Plumbing work, as defined by the Illinois State Plumbing Code, generally requires a permit and inspection by the Sangamon County Zoning and Building Safety Department. For new system installations or significant system changes, a diagram of the proposed work will be required. Examples of work requiring plumbing permits include the installation of a plumbing system, repairs to a plumbing system, and water heater replacements.
While some smaller counties in Illinois with populations below 25,000 may have minimal or no formal building code adoption for unincorporated areas, Sangamon County appears to have established procedures for building and plumbing permits. It is always advisable to confirm the specific requirements for your project directly with the Sangamon County Building and Zoning Department.

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).
