How Indiana licenses contractors

IPLA’s Plumbing Commission, Fire Sprinkler Board, and Electrical Licensing Program regulate statewide trade contractors. Many general contractor licenses remain local (Indianapolis/Marion County, Allen County, etc.). Prov (provexam.com) administers the state plumbing/fire sprinkler exams; some municipalities use PSI or ICC exams.

Northern counties need ICC Exposure C wind design and vapor control for lake-effect snow, while central Indiana deals with expansive clay and 100°F humidity, and the south braces for Ohio River flooding. Expect exam prompts about frost-depth footing insulation, tornado safe rooms, and sump pump redundancy.

A focused 4-week study plan for the Indiana exam

Because northern counties need ICC Exposure C wind design and vapor control for lake-effect snow, while central Indiana deals with expansive clay and 100°F humidity, and the south braces for Ohio River flooding, this four-week outline targets what Indiana field inspectors and your licensing board exam items actually test—not generic national prep.

  1. Week 1 — Map the exam. Pull your current candidate bulletin, list every reference, and confirm the modules you have to pass. Start a one-page error log. Spend extra time on: Indiana Plumbing Code frost depth tables and trench insulation.

  3. Week 3 — Business & Law. Indiana blends business law into each trade exam—questions cover Title 25 licensure, Title 32 liens, taxation, and safety. Layer in scenario-based questions on contracts, lien notice, payroll, and insurance.
