Illinois Contractor Insurance Requirements: Workers’ Comp First

Short answer: In Illinois, workers’ compensation is the requirement that catches solo contractors. Sole proprietors, partners, corporate officers and LLC members can normally opt themselves out — but the Illinois Workers’ Compensation Commission requires coverage anyway for extra-hazardous work, and it names construction. Fines run up to $500 for every day of noncompliance with a $10,000 minimum, and a corporate officer who knowingly goes without commits a Class 4 felony. Liability minimums come separately, from the Home Repair and Remodeling Act.

Illinois has no statewide general contractor license, which leads people to assume it has no statewide insurance requirements either. It does — written into three statutes instead of one board’s rulebook. Workers’ compensation comes from the Illinois Workers’ Compensation Commission, the liability minimums from the Home Repair and Remodeling Act, and the trade bonds and certificates from IDFPR and IDPH. Tax is separate, covered in Illinois sales tax for contractors.

Is workers’ compensation mandatory for Illinois contractors?

Yes, and the threshold is one. The Commission’s own wording is that if you have one employee, even a part-time employee, you must obtain workers’ compensation insurance, subject only to rare exceptions under Section 3 of the Act; it estimates 91 percent of Illinois employees are covered. Illinois grants no headcount grace band of the kind some states use to delay coverage until a second or third hire. Here the first person you put on a payroll — full-time, part-time or family — brings the obligation with them.

Can a one-person Illinois construction business opt out?

Illinois answers this differently for construction than for anything else.

The general rule looks generous. Sole proprietors, business partners, corporate officers and LLC members may elect not to be covered, provided they notify their insurance carrier in writing. There is no state form for it — the Commission says plainly that it neither has an opt-out form nor requires anyone to use one, which means the only evidence you were ever exempt is the letter you sent your carrier and kept. On its face, a solo remodeler could send that notice and carry nothing.

Then comes the exception that swallows it. The Commission says employees in extra-hazardous occupations must be covered despite those owner elections, and it names the categories directly: a construction business, a trucking business operating at a construction site, or other extra-hazardous occupations. Illinois also has an Employee Classification Act written specifically for the construction industry, which pushes in the same direction by making it harder to treat a construction worker as anything other than an employee.

Situation	Workers’ comp position in Illinois
Sole proprietor, non-construction, no employees	May opt out in writing
Sole proprietor, construction, no employees	Extra hazardous — coverage expected
Any employer with one or more employees	Mandatory
Corporate officers and LLC members	May opt out in writing, subject to the extra-hazardous rule

The practical effect is that the exemption most one-person businesses rely on is the one Illinois withdraws from construction, because of the injury profile of the work. If you are a one-person framing, roofing or concrete operation here, treat the opt-out as unavailable and confirm your position with the Commission or your carrier, in writing, before relying on it.

What happens if you go without workers’ comp in Illinois?

The penalties are among the harshest attached to any contractor obligation in the state, and they are not purely financial.

• Fines of up to $500 for every day of noncompliance, with a minimum fine of $10,000. The daily accrual is what makes this dangerous.
• Personal liability. Corporate officers can be held personally liable for the unpaid penalty. Incorporating is no wall against this one.
• Criminal exposure for corporate officers. The Commission states that corporate officers found to have negligently failed to obtain insurance are guilty of a Class A misdemeanor, and those found to have knowingly failed to obtain it are guilty of a Class 4 felony. Note who that lands on: an officer, personally, not an abstract company.
• Work-stop orders. The Commission may halt all business operations until you produce proof of insurance.
• Loss of the Act’s protections. An employer that knowingly fails to insure loses the protections the Act normally provides, and an employee injured during the uninsured period may sue the employer in civil court, where benefits are unlimited.

That last point is worth sitting with. Workers’ compensation is not only a cost — it is a cap on what an injury can cost you. Dropping it does not remove the liability; it removes the ceiling.

Is general liability insurance required in Illinois?

For residential work, yes — by statute rather than by a licensing board. Section 25 of the Home Repair and Remodeling Act requires anyone in the business of home repair and remodeling to obtain and maintain, in full force and effect during the operation of the business, public liability and property damage insurance at these minimums. The Attorney General posts the Act as enacted, Public Act 91-0230, effective January 1, 2000:

Coverage	Minimum
Bodily injury, per person	$100,000
Bodily injury, per occurrence	$300,000
Property damage, per occurrence	$50,000
Improper home repair or remodeling not in conformance with applicable State, county or municipal building codes, per occurrence	$10,000

There is one way out, and it is not practical for most readers: the requirement does not apply to a person with a net worth of not less than $1,000,000, as determined on the basis of their most recent financial statement, prepared within 13 months.

That fourth row deserves attention because it is unusual. Illinois requires a specific slice of coverage for work that fails to conform to code — a hazard many standard policies treat carefully. Ask your broker to confirm in writing that your policy satisfies it.

Check whether the job is even inside the Act before you assume it is. Illinois defines a “residence” for this purpose as a single-family home or a multi-family building of six or fewer units, and the Act does not reach original construction of single-family or multi-family residences, or repairs to dwellings with more than six apartments or family units. Maintenance, service or repairs under $500 fall outside the definition of home repair and remodeling entirely. None of that touches your workers’ compensation duty, which turns on employment rather than on the kind of building.

Because this obligation lives in a consumer-protection statute, Section 35 makes any violation of the Act a violation of the Illinois Consumer Fraud and Deceptive Business Practices Act, and puts enforcement with the Attorney General or a State’s Attorney. Whether you carry this personally or through an entity is one of the arguments in do I need an LLC to freelance.

What insurance do the state-licensed trades have to carry?

Illinois licenses only two trades statewide, and each attaches its own financial security on top of everything above.

Roofing (IDFPR, 225 ILCS 335). A surety bond, written by a bonding company licensed in Illinois onto the Department’s own form — BD-LRF for a limited license, BD-URF for an unlimited one — with the instruction that you must not change the language on it. Plus workers’ compensation for your roofing employees, evidenced either by a certificate of insurance or by the Workers’ Compensation Commission’s Certificate of Approval as a Self-Insurer; if the business sits in another state, the out-of-state policy needs an all-state endorsement or a clause covering Illinois accidents on the Illinois benefit schedule. Plus public liability and property damage insurance, proved only on IDFPR’s RF-INS form completed by the insurer. Plus a Statement of Account from the Illinois Department of Employment Security showing your unemployment insurance account number and no delinquency. IDFPR sets the bond and insurance amounts by rule rather than on the application, so take those figures from the Department or the Roofing Industry Licensing Rules — not from a blog, and not from this page.

Plumbing contractors (IDPH, 225 ILCS 320; 77 Ill. Adm. Code 894). Here the numbers are printed on the registration application IDPH posts (form IL 482-0679), which requires a certificate of insurance showing, per occurrence, $100,000 general liability, $300,000 bodily injury, $50,000 property damage and $500,000 workers’ compensation, naming the Illinois Department of Public Health, Plumbing Program, Springfield, as certificate holder. The Department accepts no binders and no continuous certificates; the name on the certificate must exactly match the business name on the application; the certificate must be good for at least 60 days after registration issues and stay in force throughout; and you or your insurance representative must notify IDPH in writing at least 30 days before any cancellation, material alteration or expiration. Let it lapse and the registration is suspended — which also stops your apprentices accruing time. Separately, a $20,000 surety or indemnification bond, or a letter of credit in the same amount, naming the Department as beneficiary, on the Department’s form, expiring September 30 of the current year and never continuous. The registration itself expires September 30 too. Because that form carries an older revision date, confirm the current schedule with IDPH before you write the cheque.

The plumbing rules hold the one genuine solo carve-out in Illinois contractor insurance: a plumbing contractor with no employees may elect to be exempt from workers’ compensation, using IDPH’s Affidavit of No Employees together with its Workers’ Compensation Opt-Out form — two separate documents on the Department’s forms page. That is a registration-level accommodation, not blanket permission, and it does not resolve the Commission’s extra-hazardous rule for a plumbing contractor actually performing construction work. If that is you, confirm your position with the Commission rather than assuming the IDPH filing settles it.

Does Illinois require a bond or a home warranty?

Not statewide for general contractors, for the same reason there is no statewide general contractor license: there is no state credential for a bond or recovery fund to attach to. The statewide bonds that exist are the trade ones above.

Bonding for general work is municipal. Chicago and many other Illinois cities attach their own bond and insurance conditions to a local general contractor license, and in Chicago’s case those conditions vary with the licence class. This page quotes no figures for them, because each jurisdiction publishes and revises its own — check the building department where the job sits before you bid. The licensing side is in Illinois contractor license requirements.

Nor is there a statewide home warranty obligation or contractor recovery fund. That follows from the same structural fact: with no statewide general contractor license, there is no state credential for such a scheme to hang on. Any warranty you offer is a contract term, so it belongs in the written contract the Home Repair and Remodeling Act already requires over $1,000.

How does subcontracting change your exposure in Illinois?

Calling someone a subcontractor does not settle whether they are one. Illinois has an Employee Classification Act aimed squarely at the construction industry, and the label in the paperwork is not the test — what the parties actually do is. Do not assume that a contract describing a worker as an independent contractor, on its own, discharges your workers’ compensation duty toward that worker; that question is decided on the facts of the working relationship, and it is decided after the injury, not before it.

So your own certificate is only half the file. If you bring on subs, collect their current certificates of insurance and re-collect at renewal, not only at the start. An expired sub certificate is how a solo operator ends up carrying an injury it never priced for.

What paperwork does insurance compliance actually run on?

Certificates, dates and per-job records: proof of coverage for the period a claim relates to, sub certificates matched to the jobs they worked, contracts showing the agreed scope. If the Commission asks whether you were covered on a specific day two years ago, an emailed PDF you cannot find is the same as no coverage.

That is a record-keeping problem, not an insurance one. Keel is an iOS app that keeps those records entirely on the device — no account, no bank connection, no cloud sync, App Store privacy label reading Data Not Collected. It produces invoice PDFs with your own numbering, logo and payment-link QR code; captures receipts read on-device with Apple Intelligence; logs mileage; gives you a Freeboard and reports; and writes everything into an append-only, hash-chained ledger exportable as one file per year or as an Accountant Pack. Free is $0 with unlimited invoices, receipts and mileage; Keel Pro is a one-time $249.99 Lifetime purchase.

Keel does not sell insurance, file with the Commission, or issue certificates — it is a record keeper, holding the job-level trail a comp audit, a liability claim or a Home Repair and Remodeling Act dispute is argued from. If that trail lives in a truck console, a contractor receipt organizer is where to start.

Frequently asked questions

Do I need workers’ compensation as a solo contractor in Illinois?

Almost certainly, if you do construction. Illinois lets sole proprietors, partners, corporate officers and LLC members opt out in writing — but the Commission requires coverage for extra-hazardous work and names construction and trucking at construction sites. Treat the opt-out as unavailable in construction and confirm your position with the Commission or your carrier.

What is the penalty for no workers’ comp in Illinois?

Up to $500 for every day of noncompliance with a $10,000 minimum fine, plus possible personal liability for corporate officers and a work-stop order halting the business. Corporate officers who negligently fail to insure are guilty of a Class A misdemeanor; knowing failure is a Class 4 felony. An employer that knowingly fails to insure also loses the Act’s protections, so an injured employee may sue civilly with unlimited benefits.

How much liability insurance does Illinois require for home remodeling?

Section 25 of the Home Repair and Remodeling Act sets $100,000 per person and $300,000 per occurrence for bodily injury, $50,000 per occurrence for property damage, and $10,000 per occurrence for improper work not conforming to applicable State, county or municipal building codes. It does not apply to a person with a net worth of not less than $1,000,000 on a financial statement prepared within 13 months.

Do Illinois roofers need a bond?

Yes. IDFPR requires a surety bond written by a bonding company licensed in Illinois on the Department’s own form — BD-LRF for a limited roofing license, BD-URF for an unlimited one — and the amount is set by the Department’s rules rather than on the application, so confirm it with IDFPR. Roofers must also carry workers’ compensation for roofing employees or hold the Commission’s Certificate of Approval as a Self-Insurer.

Can an Illinois plumbing contractor with no employees skip workers’ comp?

For IDPH registration purposes, yes — a plumbing contractor with no employees may elect to be exempt, filing the Department’s Affidavit of No Employees together with its Workers’ Compensation Opt-Out form. That is a registration accommodation, not a general exemption, and it does not resolve the Commission’s extra-hazardous rule for construction work.

Does Illinois require a home warranty from contractors?

No. There is no statewide home warranty or contractor recovery fund in Illinois, which follows from there being no statewide general contractor license for one to attach to. Any warranty you give is a contract term, so it belongs in the written contract the Home Repair and Remodeling Act already requires over $1,000.
