How to get licensed as a contractor in Indiana
Indiana licenses exactly one construction trade at the state level: plumbing, through the Indiana Plumbing Commission under the Professional Licensing Agency. General contractors, electricians, and HVAC contractors are licensed or registered by cities and counties instead, which means requirements shift every time you cross a municipal line. The practical path is a plumbing license if you need one, plus registrations in each jurisdiction where you pull permits.

When a license is required
There is no statewide dollar threshold or general contractor license in Indiana. Plumbing work requires a state license at any amount. For all other trades and for general contracting, the licensing requirement and any thresholds come from the city or county issuing the permit.
License classes in Indiana
Plumbing license
The one state-level construction credential, issued through the Indiana Plumbing Commission with apprentice and journeyman-to-contractor progression. Some cities also ask plumbers to register the state license locally.
Local general contractor registration
Cities and counties, including Indianapolis and Marion County, register or license general contractors with insurance, bond, and fee requirements that vary by jurisdiction.
Local trade licenses
Electrical, HVAC, and wrecking licenses are municipal in Indiana. A license from one city may or may not be honored in the next one over.
What you need before you apply
- For plumbing: complete an approved apprenticeship and pass the state exam
- For everything else: each jurisdiction's registration or license application
- General liability insurance at the limits your cities require
- A surety bond where the local ordinance demands one
- Workers compensation coverage for employees
- A registered business entity with the Indiana Secretary of State
How to get licensed in Indiana
- Map your permit jurisdictions. List the cities and counties where you expect to work. Indiana licensing is local-first, so that list is your actual application list.
- Sort the plumbing license if it applies. Plumbing is the only state-licensed trade, with an apprenticeship and exam path through the Plumbing Commission. Nothing local substitutes for it.
- Register with each building department. Submit each jurisdiction's contractor registration with insurance certificates, bond if required, and the fee. Indianapolis and Marion County have the most defined process.
- Verify trade rules town by town. Electrical and HVAC licensing is municipal, and reciprocity between towns is inconsistent. Ask before bidding, not after winning.
- Track renewals. Each registration renews on its own schedule with its own fee. Keep a calendar so an expired registration never blocks a permit mid-project.
Reciprocity with other states
With no state general contractor license, there is nothing to transfer at the state level; each municipality decides what evidence of competency it accepts, and some honor neighboring cities' licenses. The state plumbing license is Indiana-specific, though the commission can evaluate out-of-state experience toward eligibility.
Working without a license
Unlicensed plumbing work risks state enforcement through the Professional Licensing Agency. Otherwise penalties are local: fines under municipal ordinances, stop-work orders, and permit denial, which in practice shuts a job down fast. Confirm requirements with each building department, since local ordinances change without statewide notice.
Frequently asked questions
Does Indiana have a state general contractor license?
No. Plumbing is the only construction trade Indiana licenses statewide. General contractors register with cities and counties, and each jurisdiction sets its own insurance, bond, and fee requirements.
Do handymen need a license in Indiana?
Not from the state, unless the work is plumbing. Whether a handyman needs local registration depends on the town and whether the work needs a permit. Small non-permitted repairs are typically unregulated, but permitted work usually requires a registered contractor.
What does Indianapolis require from contractors?
Indianapolis and Marion County register contractors through their permitting authority, with insurance and bonding requirements that depend on the work type. Registration is checked when you apply for permits. If you work in the metro suburbs too, expect separate registrations in each town.
Can I use my Ohio or Kentucky license in Indiana?
There is no state license to transfer it to. Individual municipalities decide what they accept as proof of qualification, and policies vary. For plumbing, apply through the Indiana Plumbing Commission, which can weigh your out-of-state experience.
