Indiana's Plumbing Corporation License and the Qualifier Requirement in IC 25-28.5-1-13

Indiana does not use the phrase "qualifying agent" anywhere in its plumbing statute. It does not need to. The requirement is written into Indiana Code 25-28.5-1-13 in language that is harder to work around than most states that do use the term.

Here is the operative rule. A corporation engaged in the business of a plumbing contractor must itself be licensed as a plumbing contractor. And that corporation may not be licensed unless one of its officers or employees holds a valid plumbing contractor license issued by the Commission. That individual must be designated in the application and named in the license.

Three words carry the weight: officers or employees. Indiana gives a company exactly two lawful ways to attach a licensed plumbing contractor to itself. Make the person an officer of the corporation, or employ them. The statute contemplates no third category, and the license that results has that person's name printed on it.

This is now the fifth state whose primary law states the qualifier relationship in ownership-or-employment terms rather than leaving it to inference. Read together, those five statutes describe a national pattern that the license-rental market depends on people not noticing.

What Indiana Actually Says

Indiana Code 25-28.5-1-13 governs applications by corporations, partnerships, and associations. Its requirements for a corporate plumbing contractor license are:

1. The corporation must be licensed as a plumbing contractor in its own right.
2. It may not be licensed unless one of its officers or employees holds a valid plumbing contractor license issued by the Indiana Plumbing Commission.
3. That officer or employee must be designated in the application and named in the license.
4. The application must be signed by the applicant or the applicant's duly authorized officer or officers.

The Indiana Professional Licensing Agency's own corporate licensing instructions restate the first requirement in plain English: "To qualify for a Corporate Plumbing Contractor License you must be licensed as a Plumbing Contractor in the State of Indiana." A business providing plumbing services that must file a certificate of assumed business name under Indiana Code 23-0.5-3-4 also has to register the business name, address, and telephone number with the Commission.

The Enforcement Mechanism Most States Do Not Have

Plenty of states require a qualifier at the point of application. Fewer states check again.

Indiana checks at every renewal. From the IPLA's published plumbing renewal instructions: plumbing corporation licenses expire December 31 of every odd-numbered year, and "Corporations must confirm and indicate the responsible licensed Plumbing Contractor on file with their license in order to renew."

That single sentence changes the risk profile of the whole arrangement. A qualifier requirement enforced only at application is a hurdle you clear once. A qualifier requirement enforced at renewal is a continuing condition of the company's existence as a licensed entity. The corporation does not merely need to have had a named licensed plumbing contractor at some point. It needs one, on file, identified by name, every two years, forever.

Lose that person and you do not have a compliance gap to paper over at your convenience. You have a corporate license that cannot renew.

The Contingency Provision, and What Its Eligibility Line Gives Away

Indiana wrote an emergency valve into the statute, and reading who is allowed to use it tells you exactly what the legislature assumed the qualifier relationship looked like.

Indiana Code 25-28.5-1-18.5 authorizes the Commission to issue a temporary plumbing contractor's license to an applicant "who has an ownership interest in or is an officer of a contracting business" when the plumbing contractor licensee operating that business has died or is physically or mentally unable to operate it. The license runs only for the period needed to dispose of the business or otherwise meet the emergency, and it may not exceed two years including all renewals.

Under 860 IAC 1-1-8 the temporary license issues in six-month increments at $25 each. The applicant's current or future employer must submit a letter confirming employment, and a personal appearance may be required. 860 IAC 1-1-8(d) provides that no temporary license will be issued to an applicant who fails to first appear before the Commission or the executive director of the Indiana Professional Licensing Agency to request it.

Now look at who qualifies for that lifeline: an owner or an officer. Not "anyone at the company." Not "a person who had a business relationship with the licensee."

Indiana's assumption is visible in the drafting. The legislature took for granted that when a licensed plumbing contractor dies or is incapacitated, there will be an owner or officer of that business standing close enough to the operation to step in and wind it down or carry it forward. That assumption is only true if the licensed contractor was genuinely embedded in the company, an officer, or an employee working alongside owners and officers who know the business.

A company whose only connection to a plumbing contractor license was a name on a form has nobody eligible to invoke Section 18.5. The bridge exists. It simply is not built for that company. And the corporate license cannot renew without the name that just disappeared.

We cover the operational version of that scenario in what happens when your qualifier leaves.

Five States, One Pattern

Indiana joins four other states whose primary law describes the qualifier relationship in terms of ownership or employment rather than leaving it undefined. Put side by side, the pattern is difficult to argue with.

Five states. Five different vocabularies, corporate officer or employee, engaged as an employee, designated supervisor, bona fide representative, responsible managing employee. One structure underneath all of them.

The qualifying individual is inside the company. They own part of it, they are an officer of it, or they are employed by it. Not one of these statutes describes a licensed individual who lends a credential to a business they are not part of, and not one of them creates a category for a contractor-for-hire who attaches a license to a company from the outside.

That is not an interpretation. It is what the words say, in five different states, drafted independently, decades apart.

What This Means for the "Rent a License" Offer

Somebody will offer to let an Indiana plumbing corporation use their license number for a monthly fee, no employment, no equity, no involvement.

Run that against Indiana Code 25-28.5-1-13 and see where it lands. The corporation must name an officer or employee holding the contractor license. Your prospective renter is neither. To submit the application you would have to represent to the Commission that this person occupies a relationship with your company that they do not occupy. That representation goes on a signed application, and the license that issues carries their name on it.

Then it repeats. Every renewal, the corporation must confirm and indicate the responsible licensed plumbing contractor on file. Every two years, the same representation, re-affirmed.

And the exposure is not only the company's. The individual's name is on the corporate license. Indiana's disciplinary process under IC 25-28.5-1-28 reaches the licensee. On the other side of the ledger, Indiana makes acting or advertising as a plumbing contractor without a license a Class A misdemeanor under IC 25-28.5-1-31(a), and under IC 25-28.5-1-36 no action or suit may be instituted in any Indiana court to recover compensation for plumbing contracting services by a person not licensed or registered under the chapter. A company operating on a license it does not properly hold is one complaint away from finding out whether its work was ever collectible.

Neighboring states have made the point in even blunter terms. Missouri names "allowing any person to use his or her license" as a disciplinary cause under RSMo § 324.940(4)(6), and Kansas City requires its qualified supervisor to be a full-time managerial employee serving only one company at a time, a clause that makes the multi-company rented-qualifier model structurally impossible rather than merely risky.

The full argument, with the primary sources from every state we have examined, is in is it legal to rent a contractor license.

The Compliant Version

There is nothing wrong with a plumbing corporation that does not have a licensed plumbing contractor among its founders. That is an ordinary situation, and Indiana's statute anticipates it, that is precisely why it says "officers or employees" rather than "officers."

The employment route is not a workaround. It is one of the two routes the legislature wrote.

What compliance requires is that the arrangement be what it says it is. The licensed plumbing contractor named on your corporate license should be a genuine part of your company: a full-time W-2 employee with real duties, real supervision responsibility, real payroll, and a real reason to care whether the work is done correctly. That is what makes the name on the license accurate, what makes the renewal attestation true, and what puts an actual person in position if Section 18.5 is ever needed.

That is the only model we operate. Qualifying agents are placed as full-time W-2 employees of the licensed business. Not a percentage of revenue, not a flat fee per project, not per engagement, not 1099, and not a license lent from the outside. Indiana's statute happens to state the reason with unusual clarity, but the reason holds in every state: the law describes an insider, so the relationship has to be one.

Frequently Asked Questions

Does Indiana require a qualifying agent for a plumbing company? In substance, yes, though the statute does not use that term. Under IC 25-28.5-1-13 a corporation cannot be licensed as a plumbing contractor unless one of its officers or employees holds a valid Indiana plumbing contractor license, designated in the application and named in the license. The Commission also requires corporations to confirm the responsible licensed plumbing contractor on file in order to renew.

Can an Indiana plumbing qualifier be a 1099 independent contractor? The statute authorizes two relationships: officer, or employee. An independent contractor is neither. A person providing services to your company as an outside contractor while their name sits on your corporate license does not match the category the statute describes, and the same representation has to be re-affirmed at every renewal.

What happens if our named plumbing contractor leaves? The corporate license cannot renew without a responsible licensed plumbing contractor confirmed on file. If the licensee died or became physically or mentally unable to operate the business, IC 25-28.5-1-18.5 allows an owner or officer of the business to apply for a temporary plumbing contractor license, issued in six-month increments and capped at two years including all renewals. That relief is available only to an owner or officer, and only in those circumstances. An ordinary departure is not covered.

Can one licensed plumbing contractor qualify several Indiana companies? Indiana's plumbing chapter does not state a numerical limit the way Kansas City's ordinance does with its "only one company at a time" rule for designated supervisors. But the practical test is whether the officer-or-employee relationship in IC 25-28.5-1-13 is genuine as to each company. A person cannot plausibly be a real officer or a real employee of an unlimited number of unrelated plumbing corporations, and each corporate license carries their name and their exposure.

How much does it cost to bring in a qualifying agent? There is no published price, because there is no standard one. It turns on the state, the trade, the license class, the risk the licensed individual is absorbing, the volume and type of work being qualified, and how long the arrangement needs to run. Anybody quoting a flat national figure is quoting something other than your situation. We scope it per company; see consultation packages.

Is the Indiana requirement stricter than other states? It is among the more explicit. Naming the individual in the license and re-confirming them at every renewal is stronger enforcement than most states apply. Wisconsin's "engage, as an employee" language in § SPS 305.31(1)(b) is the most direct statement of the employment requirement we have found; Indiana's is the clearest statement of the ownership-or-employment binary.

The Takeaway

Indiana's plumbing statute quietly settles a question that a lot of the contractor licensing market would rather leave open.

A plumbing corporation in Indiana is licensed only if a licensed plumbing contractor is an officer or an employee of that corporation, designated in the application and named in the license, and re-confirmed on file at every two-year renewal. The state's own emergency provision reserves the temporary bridge license to owners and officers, the people it assumed would be there.

There is no category in that statute for a license attached to a company from the outside. There is no category for it in Wisconsin, Missouri, New Jersey, or Hawaii either.

The compliant answer, in Indiana and everywhere else, is to have the right person actually working for you. If you need one, start with what a qualifying agent is and how we place qualifying agents as full-time W-2 employees. If you hold an Indiana plumbing contractor license and want to understand what that credential is worth to a company that legitimately needs it, see becoming a qualifying agent.
