Lake County, Indiana Plumbing Permit Requirements

In Lake County, Indiana, plumbing permit requirements are primarily governed by the Lake County Building Code No. 18, which adopts by reference the Indiana Plumbing Code 2012 edition. This code is based on the 2006 International Plumbing Code with Indiana amendments. For properties in unincorporated areas of Lake County, permits are required before commencing any construction, alteration, repair, or maintenance of any building or structure. This includes plumbing work.

Plumbers working in the unincorporated areas of Lake County must be registered with the Licensing Division of the Lake County Planning & Building Department. While plumbers holding a valid Indiana Plumbers License are not required to take a separate test for registration, they must still register. Additionally, contractors performing work in these areas are required to have a recorded County Unified Bond of $5,000 and a Certificate of Insurance.

Permit applications for building projects, including plumbing, must be accompanied by a plat or sketch of the property, legal description, and detailed plans and specifications. The Lake County Plan Commission's Building Division is responsible for reviewing these applications. For commercial buildings, additional inspections may be required, and final approval letters from various agencies are necessary before a final inspection can be scheduled.

The Indiana Department of Homeland Security (IDHS) Division of Fire and Building Safety administers the Indiana Plumbing Code, which is a modified version of the International Plumbing Code (IPC) and the International Residential Code (IRC). Indiana-specific amendments take precedence over the base code language where conflicts arise.
