Indiana Contractor License Exam Guide (2026)

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.

Indiana contractor license types

State trade contractors must show four years of journeyman-level experience, proof of liability insurance, and bonding (typically $5,000). Municipal GC applicants submit financial statements, $10,000–$30,000 bonds, and ICC pass letters.

What's on the Indiana contractor exam

Prov operates centers in Indianapolis, Fort Wayne, Evansville, Merrillville, and Bloomington. PSI handles some municipal ICC-based exams.

What Indiana exam questions emphasize

• Indiana Plumbing Code frost depth tables and trench insulation
• Floodplain and sump/discharge requirements under 675 IAC 16
• Lien law calculations for Title 32 (pre-lien notice deadlines, 60-day filing)
• OSHA 1926 trench safety and confined space protocols

Exam-day logistics

• Bring your Authorization to Test plus two IDs; arrive 30 minutes early for sign-in
• Reference lists are limited—tab the Indiana Plumbing Code, NFPA manuals, and Title 25 book
• Failing candidates can reschedule after 24 hours; scores stay valid for 1 year

Who needs an Indiana contractor credential (and who does not)

IPLA regulates plumbing, fire sprinkler, and electrical contractors statewide. Indianapolis and other cities license GCs locally.

• Floodplain and sump/discharge requirements under 675 IAC 16

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.
2. Week 2 — Code book navigation. Drill open-book lookups (or memorisation drills if your module is closed-book) until you can find any answer in under 60 seconds. Anchor practice around: Floodplain and sump/discharge requirements under 675 IAC 16.
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.
4. Week 4 — Full simulations. Prov operates centers in Indianapolis, Fort Wayne, Evansville, Merrillville, and Bloomington. PSI handles some municipal ICC-based exams. Run two full-length timed simulations. Review every miss with a one-sentence rule statement.
