Does Illinois Require a Licensed Plumber? What Homeowners Should Ask

This trips up a lot of homeowners. You hire a construction company, a truck shows up, and you assume the company holds some kind of blanket plumbing license. In Illinois that is not how it works. The Illinois Department of Public Health licenses individual plumbers — the people who plan, inspect, install, alter, extend, repair and maintain plumbing systems.

So the right question is not "is your company licensed?" It is "who is doing the plumbing on my house, and is that person licensed?" Those are two different questions and only the second one has a verifiable answer.

You can read the state's own description of the program on the https://dph.illinois.gov/topics-services/environmental-health-protection/plumbing.html page. It is short and worth five minutes before you sign anything.

According to IDPH, licensure in Illinois comes after a licensed apprenticeship that runs roughly 48 to 72 months, followed by a state examination. That is four to six years of supervised work before someone sits for the test.

Licensed plumbers also complete annual continuing education to keep the license current. This matters because plumbing code changes, and a license issued years ago with no upkeep is not the same thing as a current one.

The length of that apprenticeship is the honest reason plumbing work costs what it costs. You are paying for someone who spent years learning what happens behind a wall before they were allowed to work on yours.

Variety Pros LLC is a general construction and remodeling company. On plumbing we handle issue review, fixture project planning and renovation plumbing coordination, and we bring in qualified trade contractors to perform the licensed work. Brandon Willis discusses scheduling and next steps with you directly.

That phrase — coordinating licensed trades — should never be vague. If you are hiring us or anyone else in the Chicago area, you are entitled to know who the plumber is before work begins, not after. Ask for it in writing.

Our written estimates identify allowances, exclusions and permit responsibilities so nobody is guessing at the halfway point. You can see the full scope of what we handle on our plumbing services page.

One: who specifically is performing the plumbing work, by name or by firm? Two: is that person licensed in Illinois, and can you see the credential? Three: who is responsible for pulling the permit — you, the general contractor, or the plumber? Four: what is excluded from the price?

The fourth question saves the most arguments. Exclusions on a plumbing scope often cover things like unexpected conditions inside walls, replacing supply lines that were not part of the original scope, or restoration of finishes after access is cut. None of that is unfair — it just needs to be written down before the first cut.

A contractor who answers all four without hesitating is telling you something useful about how the rest of the job will go.

Plumbing permits are a municipal matter in Illinois, and the rules differ village to village. Moving a fixture, adding a bathroom, re-piping, or any work that changes the drain, waste and vent layout commonly triggers a permit. Swapping a faucet usually does not. The line between the two is set by your own municipality, not by a general rule you read online.

Many suburbs also require the contractor to be registered with the village before a permit application will even be accepted. Tinley Park, for example, requires contractor registration with a valid license and current certificate of insurance before a permit account can be created.

We will not state permit requirements for your project before we have looked at the scope, and we would be careful about any contractor who does. Confirm with your own building department. If you are in the southwest suburbs, our Orland Park building permit guide walks through how that process looks at the village level.

We schedule by appointment, Monday through Saturday, Central time. We do not guarantee emergency or after-hours availability — if your situation is urgent, call and we will tell you honestly what we can confirm for that day rather than promising a window we cannot hold.

If water is actively running and you cannot stop it, shut off the supply at the fixture or at the main before you make any calls. That single step limits the damage more than anything a contractor can do in the next hour.

You can reach us at (312) 585-6226 or willisb245@gmail.com, or through our contact page. We offer same-day or next-day estimates, subject to availability being confirmed when you call.

Tell us where the water is showing up, when it started, and whether it is constant or only during use. A ceiling stain that appears only when the upstairs shower runs points somewhere very different than one that grows all day.

Note the age of the house if you know it, and whether anything was worked on recently. A problem that began two weeks after an unrelated remodel is a clue, not a coincidence.

Photos help. A picture of the fixture, the shutoff and the visible damage, sent before the visit, often means we arrive with the right parts instead of scheduling a second trip. Every project is quoted on site after we have seen the actual conditions.
