Indiana Contractor License & Trade Guide

Indiana licenses relatively little at the state level. Plumbing is the primary mainstream statewide trade, while radon, water-well drilling, asbestos and lead sit in specialty state programs. General contracting, electrical, HVAC, roofing, concrete and masonry are primarily local jurisdiction questions. This guide turns that split into practical permit-routing intelligence.

01 · Licensing model

How Indiana Actually Licenses Contractors

Indiana’s defining rule is the split between a small number of statewide specialty credentials and a much larger local licensing/registration layer.

There is no one Indiana contractor license.

The supplied source identifies plumbing as the primary mainstream statewide contractor credential, with radon, water-well drilling, asbestos and lead as separate specialty programs. Electrical, HVAC, general contracting, roofing, concrete and masonry are handled locally.

Important correction preserved from the source: IC 25-28.5 is the Plumbing article. Do not build a statewide electrical or HVAC gate against IPLA based on that statute.

02 · Market-defining credentials

The Codes That Shape the Market

Wide horizontal rows keep every label readable. Only codes supported by the source are treated as credentials; local labels are clearly described as routing labels.

06 · Operating checklist

What Contractors Should Verify

Indiana is jurisdiction-sensitive. Do not use one state lookup as a substitute for the project’s local building department.

Jurisdiction

Identify the city/county/AHJ before deciding which contractor gate applies.

State specialty credential

Check IPLA, DNR, IDEM or the relevant health authority where the trade is state regulated.

Local license / registration

For GC, electrical, HVAC, roofing, concrete and masonry, verify the local jurisdiction.

Exact role

Distinguish business contractor credentials from individual journeyman, worker, supervisor or tester credentials.

Permit status

Permit issuance identifies activity and timing but does not establish an open bid or guaranteed job.

Current rules

Use the live agency and local record because forms, license formats and ordinances can change.

07 · Primary authorities

Official Indiana Sources

Use these live agency resources for final credential verification. This guide is a routing aid and preserves the caution in the supplied source where a statewide credential was unconfirmed.

08 · FAQ

Indiana Contractor Licensing Questions

Fast answers to the Indiana licensing questions contractors, sales teams and permit-data users are most likely to ask.

01Does Indiana have a statewide general contractor license?+

No. The supplied Indiana source states that general contracting and building contractor licensing are local rather than a single statewide GC license.

02Which mainstream construction trade is licensed statewide?+

Plumbing is the primary mainstream construction trade identified in the source as licensed statewide through the Indiana Plumbing Commission / IPLA.

03What plumbing license types does Indiana use?+

The source identifies Apprentice Plumber, Journeyman Plumber and Plumbing Contractor. It specifically says there is no separate state master-plumber license.

04Can a journeyman plumber act as the plumbing business?+

The source distinguishes the Journeyman Plumber from the Plumbing Contractor business credential. Verify the active contractor record before treating a company as eligible to contract directly.

05Does Indiana license electricians statewide?+

No. The supplied source says electrical licensing is local. Indianapolis is an example of a jurisdiction with its own electrician licensing structure.

06Does Indiana have a statewide HVAC contractor license?+

No. HVAC/mechanical contractor requirements are local in the supplied source. Refrigerant work can also involve federal EPA Section 608 certification.

07Are roofers licensed by the state?+

No statewide roofing license is identified in the supplied source. Roofing is routed to the local city or county.

08Who licenses water-well drillers?+

The Indiana Department of Natural Resources, Division of Water, is the statewide lane identified for well drillers and pump installers.

09Who regulates asbestos contractors?+

The supplied source routes asbestos contractor and operator verification to IDEM.

10Who handles radon credentials?+

The supplied source places radon testing and mitigation in the IPLA statewide licensing lane.

11Is lead abatement a separate credential lane?+

Yes. The source identifies lead-abatement workers, supervisors, risk assessors and firms as a separate state public-health credential family.

12What does an empty IPLA search mean for an electrician or GC?+

It may be completely expected. The source warns not to use IPLA as the state gate for electrical, HVAC, GC or roofing because those are local.

13Is IC 25-28.5 an electrical or HVAC statute?+

No. The supplied source explicitly flags this as a common error and says IC 25-28.5 is the Plumbing article.

14Is there a confirmed statewide fire-suppression contractor license?+

The supplied source says this was not confirmed against a primary source and intentionally leaves it off the confirmed state-license tables. This page preserves that caution.

15How should TigerLeads route Indiana permit records?+

Start with the project jurisdiction, then decide whether the work is in a statewide specialty lane such as plumbing, radon, well drilling, asbestos or lead, or a local-only lane such as GC, electrical, HVAC and roofing.

16Does a permit mean the job is open for bidding?+

No. A permit is a project signal and timing indicator, not proof of an open bid, available subcontract or guaranteed sales opportunity.

17Should local registration be checked in addition to state credentials?+

Yes. Even when a state specialty license applies, the permit jurisdiction can impose local registration, permit or insurance requirements.

18How often should Indiana license information be rechecked?+

Recheck the live agency and local jurisdiction whenever relying on a credential because license formats, local ordinances, forms and verification systems can change.
