Illinois Umbrella and Excess Liability Guide

Illinois public contracts illustrate why you need the actual schedule: a Will County easement insurance clause in IDOT-hosted 2024 contract documents allows lower primary limits when umbrella or excess policies bring general liability to $4 million per occurrence and auto to $1 million, while a 2024 Cahokia Heights sewer-repair specification calls for $5 million per occurrence and aggregate in excess/umbrella liability. These are project terms, not statewide business limits. Ask what each layer covers, whose interests are insured, and whether the aggregate is dedicated to your project. 1,2

What Is Umbrella And Excess Liability?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. Read the national Umbrella and excess liability guide.

Illinois Requirements

RequirementDetails
Will County easement agreement example (IDOT-hosted 2024 document)For contractors working on the Will County easement premises maintained by ComEd, the IDOT-hosted letting clause allows lower limits in its first coverage schedule if umbrella/excess brings general liability to $4 million per occurrence and auto to $1 million and satisfies all other terms. A separate schedule states a $4 million general-liability requirement. This is one easement agreement, not an Illinois-wide limit. 1
Cahokia Heights sewer-repair contract exampleThe August 2024 sewer-repair specifications set $5 million per occurrence and aggregate for excess/umbrella, alongside $1 million each-occurrence CGL, $2 million CGL aggregates, and separate contractor pollution liability. The completed-operations period and required endorsements also apply under that specific contract. 2

What to Watch for in Illinois

  • Compare aggregate limits and dedication

    The Cahokia Heights specification states both a $5 million occurrence limit and a $5 million general aggregate. The Will County easement clause in the IDOT-hosted contract focuses on a total per-occurrence limit while separately allowing lower primary limits. Check the aggregate wording and whether it applies per project; the same headline excess limit can leave different remaining capacity after multiple claims. 2,1

  • Pollution is a separate question on these projects

    The Will County easement clause in the IDOT-hosted contract triggers pollution legal liability for hazardous-substance or pollutant handling, transport, disposal, or operations; the Cahokia Heights sewer-repair schedule separately specifies contractor pollution liability and a three-year post-completion period. Do not assume an umbrella follows or expands that separate pollution coverage; check whether the hazard and completed operations are insured on the required terms. 1,2

  • Track every contractor whose work is covered

    The Cahokia Heights general conditions extend insurance requirements to contractors and subcontractors and require additional-insured status for the owner and engineer, including ongoing and completed operations. Before work starts, compare the actual subcontractor schedule and endorsements with the contract; a prime’s umbrella certificate alone does not show that each subcontractor qualifies as insured under it. 2

  • Completed-operations duration affects renewal planning

    The Cahokia Heights documents call for products/completed-operations coverage for three years after final payment and state a $4 million CGL occurrence limit in the general conditions, with a separate $5 million excess schedule. If the project contract includes this period, ask how the primary and excess policies maintain coverage for work completed earlier, rather than comparing limits only for the active construction period. 2

Who Regulates Insurance in Illinois

Illinois Department of Insurance

The Department licenses and oversees insurers and insurance producers doing business in Illinois, reviews regulated insurance activity, and investigates complaints about coverage, claims, premiums, and sales. 3,5,4

Surplus-lines tax and stamping office

Reported tax rate: 3.5% of taxable premium plus a 0.04% stamping fee; separate 1% fire marshal tax on taxable fire premium When Illinois is the insured’s home state, the broker reports and remits a 3.5% tax on gross taxable surplus-line premium less returned taxable premium. The separate SLAI stamping fee is 0.04% for policies effective on or after January 1, 2023; a 1% fire marshal tax also applies to taxable fire premium. 7,6,10,11,8

Surplus Line Association of Illinois

  • Illinois guaranty fund limits: For covered claims against a member insurer, the Illinois Insurance Guaranty Fund generally caps its obligation at $500,000 per claim; workers’ compensation claims are excepted from that dollar cap. This fund does not protect policies issued by nonadmitted surplus-lines insurers. The net-worth exclusions apply to covered claims against member insurers. 8
  • Illinois FAIR Plan: If you cannot obtain basic property coverage in the voluntary market, the Illinois FAIR Plan offers a residual-market option for eligible property. Check its current eligibility and coverage limits before relying on it for a commercial location. 9

Providers With Documented State Licenses

These providers publish a national listing for Umbrella and excess liability; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Illinois. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

  • CorgiCorgi Insurance Services, Inc.Insurance producer · checked 2026-09-28Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619. New Mexico does not appear in the table and is not included here; the omission does not establish that Corgi is unlicensed there. The company-reported table has no stated as-of date and does not establish product availability. 14
  • RisklyticsRisklytics, Inc.Insurance producer · checked 2026-09-28Risklytics’ licensing page lists its Massachusetts resident agency license plus state license records in Arizona, Colorado, Illinois, Indiana, New Jersey, Ohio, Texas and Washington; it identifies the NPN record date as September 10, 2026. This list is company-published and not a product availability map. 17
  • TechInsuranceSpecialty Program Group LLCInsurance producer · checked 2026-09-28TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. 18
  • VouchVouch Specialty Insurance Services, LLCInsurance producer, Surplus-lines broker · checked 2026-09-28Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. 19

Questions to Ask Before You Buy in Illinois

  1. Which primary lines may be reduced when excess is added, and what combined limits does this particular agreement require for each?
  2. Does the umbrella/excess layer follow the required CGL, auto, and pollution terms, including additional-insured and primary/non-contributory status?
  3. Is the aggregate per project or shared across your other work, and does it remain available for completed operations?
  4. What subcontractors and additional insureds must be named, and what evidence or endorsements must each provide before work begins?

Umbrella And Excess Liability in Illinois: FAQ

Is $4 million the required Illinois umbrella limit? 1,2

No. That figure appears in one Will County easement agreement hosted in IDOT contract documents, which permits specified lower primary limits if the excess layer meets the combined requirement and other clause terms. Another Illinois public-works example uses a $5 million excess/umbrella limit. Follow the contract for your project. 1,2

Will an umbrella automatically meet an Illinois contract’s pollution requirement? 1,2

The cited contracts list contractor pollution liability separately from umbrella or excess limits. Review the actual policy schedule and endorsements for the pollution exposure the agreement identifies. 1,2
