Illinois Storm Claims: What “Bad Faith” Means—and What It Does Not

By Supreme Building Group | September 21, 2026 | Illinois homeowner guidance

After a storm claim is delayed, denied, or estimated differently than expected, homeowners sometimes describe the situation as insurance “bad faith.” The phrase is serious, but it is also easy to use too broadly. Illinois law applies specific standards, and the result depends on the facts, the policy, the communications, and—in some cases—a regulator or court.

A disagreement, slow update, or lower estimate does not by itself prove improper conduct. This guide explains the official Illinois sources, the records worth keeping, and who is qualified to handle each part of a claim. It is general information, not legal advice or a coverage opinion.

Illinois law uses more specific terms

The Illinois Insurance Code, Section 154.5, describes when conduct listed in the next section can be treated as an improper claims practice. The statute looks to knowing violations or conduct occurring often enough to indicate a persistent tendency. That is one reason a single frustrating interaction should be documented carefully rather than immediately labeled.

Section 154.6 lists examples that may matter when committed without just cause and in violation of Section 154.5. They include knowingly misrepresenting relevant facts or policy provisions, failing to acknowledge pertinent communications promptly, failing to maintain reasonable investigation and settlement standards, refusing payment without a reasonable investigation based on available information, and failing to provide a reasonable and accurate explanation for a denial or compromise offer.

Illinois also has Section 155 of the Insurance Code. In litigation involving policy liability, the amount of a loss, or an unreasonable delay in settling a claim, a court may award specified fees, costs, and an additional amount if it finds the insurer’s action or delay vexatious and unreasonable. That is a fact-specific court determination—not a conclusion a contractor should make at an inspection.

Questions homeowners can ask without making a legal conclusion

Instead of starting with a label, start with verifiable questions:

• Did the company acknowledge important written communications?

• Did it explain what information or inspection was still needed?

• Was the investigation based on the available facts and documented property conditions?

• Did a denial or compromise offer identify the policy provision, limitation, exclusion, or condition supporting the decision?

• Were repeated requests asking for information that had already been supplied?

• Is the undisputed part of the claim being handled separately from a genuine dispute?

Illinois claim-handling rules include minimum standards for communications and explanations. For example, 50 Illinois Administrative Code 919.50 addresses timely coverage decisions, payment of undisputed portions, and written explanations for certain first-party denials or offers. The exact rule that applies can depend on the claim and its procedural stage.

Build a clean record before escalating

A well-organized file helps the insurer, a regulator, a licensed public adjuster, or an attorney understand what happened without reconstructing the timeline from memory.

• Keep a communication log with the date, time, name, role, phone number, and a short factual summary of each conversation.

• Save claim letters, estimates, emails, inspection notices, proof-of-loss materials, and requests for additional information in one folder.

• Preserve original, date-stamped photographs and videos. Keep wide views that identify the area and close views that show the condition.

• Retain receipts and photographs for reasonable emergency mitigation. Separate temporary work from the proposed permanent repair.

• Ask for important decisions and requests in writing. If a phone call changes the next step, send a brief follow-up email confirming your understanding.

• Compare the insurer estimate with the actual construction scope line by line, without assuming that every difference proves misconduct.

Our delayed-or-denied claim documentation checklist provides a practical filing structure. The estimate-versus-repair-scope checklist explains how to compare quantities, materials, code-related work, access, detach-and-reset items, and documented hidden conditions.

What a contractor should—and should not—do

A contractor can inspect accessible construction conditions, photograph what is present, identify repair methods, prepare quantities and a construction scope, and document conditions discovered during repairs. That information can make the physical-property record clearer.

A contractor does not decide whether a policy covers the loss, interpret policy language for the homeowner, adjust or negotiate the claim unless separately licensed to do so, or determine that an insurer acted unlawfully. Those jobs belong to different parties. Read our contractor, insurer adjuster, public adjuster, and attorney role guide for a plain-language comparison.

How the Illinois Department of Insurance complaint process works

The Illinois Department of Insurance complaint guide recommends first contacting the insurer or agent, documenting phone calls, and keeping written communications. A complaint can then be submitted in writing through the department’s File a Complaint page.

IDOI says the company or agent is generally allowed 21 days to respond to the department and asks consumers to allow four to six weeks for an investigation. The department may ask for corrective action when it finds that the law was not followed or the policy was not honored, then sends a written explanation of its review.

IDOI also explains its limits: it cannot act as your lawyer, give legal advice, determine the value of damaged property, decide fault, or resolve a dispute that is only one person’s word against another’s. Those limits make complete written records especially important.

When other licensed help may be appropriate

Contact the insurer for the coverage decision and claim status. A licensed Illinois public adjuster may assist a policyholder with claim adjustment within the scope of that license. A qualified Illinois attorney can advise on legal rights, deadlines, policy interpretation, Section 155, and whether the facts support a legal claim. Do not wait on a blog article or contractor opinion if a deadline, lawsuit, examination under oath, appraisal demand, or other formal legal issue is involved.

Need the construction conditions documented?

If you need a photo-documented evaluation of roof, siding, gutter, or exterior construction conditions in Chicagoland, review our storm-damage inspection service or call (224) 735-4245. Supreme Building Group can document the physical condition and prepare a repair scope; we do not promise coverage or determine whether claim handling was improper.
