Mason County Plumbing Permit Requirements
Mason County, Illinois, handles electrical, mechanical, and plumbing permits for all areas within the county, including unincorporated areas. While the state of Illinois has a comprehensive Plumbing Code that applies statewide, local jurisdictions like Mason County are responsible for administering and enforcing these regulations. For properties in unincorporated areas, the county's Building Department typically oversees permit requirements.
The Illinois Plumbing Code sets minimum standards for the design, installation, alteration, and inspection of plumbing systems. Key aspects include:
- Water Supply: Minimum working pressure of 8 psi, with a maximum static pressure of 80 psi. Pressure-reducing valves are required if the supply pressure exceeds this.
- Drainage, Waste, and Vent (DWV) Systems: Minimum slope requirements for horizontal drain lines.
- Fixture Requirements: Minimum fixture counts for different occupancy types, with single-family homes requiring at least one water closet, lavatory, bathtub or shower, and kitchen sink.
- Backflow Prevention: Mandated air gaps or approved mechanical backflow prevention assemblies are required at cross-connection points to prevent contamination of the potable water supply.
- Inspections: Rough-in and final inspections are typically required before walls are closed and upon completion of the installation, respectively. Pressure testing of water supply and DWV systems is also part of the inspection process.
It is important to note that while the state code provides the framework, specific local requirements or additional documentation may be necessary. For instance, applications for new or replacement residences in Mason County may require a separate Plumbing and Mechanical Application, detailing the number of fixtures. Site plans showing septic systems, well locations, and stormwater components are also often required.

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).
