Yes. Illinois requires a home inspector licence under the Home Inspector License Act, 225 ILCS 441, administered by the Division of Real Estate at the Department of Financial and Professional Regulation rather than by a standalone inspector board. Two features distinguish it: Illinois licenses inspection entities as well as individuals, so a firm needs its own licence and a buyer should check both, and the required $100,000 general liability cover must be maintained for at least one year after each inspection report is delivered.

Illinois licenses the firm as well as the inspector
Most licensing states license people. Illinois licenses people and companies: the Act provides for a Home Inspector licence and a Home Inspector Entity licence, so a firm carrying out inspections needs its own credential alongside the individual doing the work.
This changes what a buyer should check. Verifying only the individual leaves half the question open; verifying only the company — the name on the invoice and the website — leaves the more important half open. Both records should be current, and the individual named on the report should be the one whose licence you checked.
The entity licence is a small piece of practical leverage. If a dispute arises later, you are dealing with a regulated entity rather than an unregulated business that happens to employ a licensee. Confirm both licence numbers before the inspection and record them, so that six months on you are not reconstructing who exactly you engaged.
The department also licenses education providers and approves courses separately, which is why Illinois coursework is specific to Illinois rather than national material relabelled for the state.
The cover that has to outlast the report by a year
Illinois sets a general liability minimum of $100,000, and adds a condition that few states impose: the cover must be maintained for at least one year after delivery of an inspection report.
The reason that is useful is worth spelling out. Most insurance requirements are point-in-time — cover must be in force when the licence is issued or renewed, and what happens afterwards is between the inspector and the insurer. Problems with an inspection do not surface at the inspection. They surface when the first heavy rain arrives, when the heating runs a full winter, or when a contractor opens a wall three months after closing. An inspector who let cover lapse the week after the report would leave nothing behind to respond.
Illinois closes twelve months of that gap by rule. It does not close all of it, and it is not a promise of recovery.
Two caveats. The Illinois floor is general liability, which principally answers for damage and injury; the state sets no separate errors and omissions minimum, and errors and omissions is the cover that responds when the inspection itself was wrong. And the inspection agreement may cap the inspector's liability well below the policy amount — commonly at the amount you paid. Read the clause, and ask separately whether professional liability cover is in force.
Sixty credit hours, five field inspections, and an Illinois-only examination
Entry runs through 60 credit hours of approved pre-licence instruction, which must include five field inspection events and a final field examination, before the candidate sits the written licensure examination. The field component is embedded in the course rather than served afterwards, so Illinois has no separate post-licence supervised-inspection period.
The written examination is state-specific, authorised by the department and delivered through its designated testing service, and Illinois does not use the National Home Inspector Examination. That matters for mobility: an experienced inspector relocating from an NHIE state does not carry the examination across, and sits the Illinois exam like anyone else.
For a buyer, the practical read is that "I passed the national exam" is not an Illinois qualification statement. Every current Illinois licensee passed the Illinois examination, whatever else they hold, and the licence record is what confirms it.
Standards of practice written into the administrative code
Illinois does not adopt a trade association's standards by reference. Its standards of practice sit in Subpart C of 68 Ill. Adm. Code 1410 — published state rule, amendable through the rulemaking process, and binding on every licensee.
Two things follow for a buyer holding an Illinois report. First, the scope question has a public answer: what an inspection must cover, and what may properly be excluded, is written into the administrative code and does not depend on which association the inspector belongs to. Second, if a scope disagreement develops, the Illinois rule is the yardstick — not a national association's document, however familiar.
That is a meaningful difference from states that adopt association standards or publish none. It means an Illinois report can be measured against a published requirement rather than against an impression of what inspections usually cover.
The November renewal cycle, and what a lapse does
Illinois home inspector licences renew biennially, expiring on November 30 of even-numbered years. Continuing education is twelve hours per two-year cycle, of which at least eight must come from mandatory-course content rather than being freely chosen — the department approves the courses that count.
A licence that has expired may be restored within two years of expiration under the department's restoration process. The gap between expired and restored is the interval worth caring about: an inspector working during that period is not currently licensed, whatever their history.
So read the status field rather than the presence of a number, and note the November even-year cycle if your transaction runs across that date.
Checking both licences before you rely on the report
Licence verification runs through the department's public licence lookup, reached from its check-a-licence page. Run it twice.
- The individual. Search the name of the person who will actually attend and write the report — not the name in the email signature, if they differ.
- The entity. Search the business name exactly as it appears on your engagement paperwork and invoice. Illinois issues a separate entity licence, and its absence is a real finding rather than a search failure.
In both records, read status and expiry rather than mere existence, then match the names. A firm trading under one name and licensed under another is common and usually innocuous, but you want to know which entity you contracted with before you need to rely on it.
Where the Illinois licence stops
The licence establishes that an inspector completed 60 credit hours including five field inspections and a field examination, passed the Illinois written examination, works to standards published in the administrative code, and carries at least $100,000 of general liability cover that will outlast your report by a year. That is a substantive floor.
It does not establish familiarity with your property type. A two-flat, a graystone with a century-old sewer lateral, a mid-century ranch with a finished basement below grade and a suburban new-build present different questions, and the licence does not distinguish between inspectors who know them and inspectors who do not. Ask for a full sample report on something comparable.
Nor does the licence govern the deadline. The inspection contingency in your purchase contract sets the window in which findings can still be raised or acted upon, and it does not extend because a report was late or a specialist was unavailable. Schedule so that the inspection, any specialist follow-up, the quotes and your written response all sit inside the window — because after it closes, a defect the report identified perfectly is simply a defect you now own.
Frequently Asked Questions
Do home inspectors need a licence in Illinois?
Yes. The Home Inspector License Act, 225 ILCS 441, requires a licence issued through the Division of Real Estate at the Department of Financial and Professional Regulation. Illinois issues both an individual Home Inspector licence and a Home Inspector Entity licence, so the inspection firm needs its own credential in addition to the person performing the inspection. Both should be current.
Does Illinois use the National Home Inspector Examination?
No. Illinois uses its own written licensure examination, authorised by the department and delivered through its designated testing service. An inspector who passed the NHIE in another state must still sit the Illinois examination to be licensed here. That makes the Illinois licence record, rather than a claim about a national exam, the thing to verify.
How much insurance must an Illinois home inspector carry?
General liability cover of not less than $100,000, and it must be maintained for at least one year after an inspection report is delivered — an unusual requirement, since most states only ask that cover be in force at licensure. Illinois sets no separate errors and omissions minimum, so ask whether professional liability cover, which responds to a defective inspection, is also in force.
How do I check an Illinois home inspector's licence?
Use the department's public licence lookup and search twice: once for the individual who will perform the inspection, and once for the inspection entity named on your paperwork. Read the status and expiry date rather than just confirming a number exists. Illinois licences expire on November 30 of even-numbered years, so check where your transaction sits relative to that cycle.
What standards must an Illinois home inspection follow?
The standards of practice in Subpart C of 68 Ill. Adm. Code 1410, which Illinois wrote itself rather than adopting from a trade association. They are published state rules binding on every licensee, and they define both what must be inspected and what may properly be excluded. If a scope dispute arises, that rule is the reference point, not a national association's document.
