Chicago insurance, from the two-flat to the Loop

Bungalows, two-flats, greystones and towers

Chicago neighborhoods are built from a handful of building types that repeat block after block. Brick bungalows fill the Bungalow Belt on the Northwest and Southwest Sides. Two-flats and three-flats, often with a garden unit below, line the side streets of Logan Square, Pilsen, Bridgeport and Albany Park. Greystones, the limestone-fronted two- and three-flats of the late 1800s and early 1900s, cluster along the boulevards of North Lawndale and the South Side. Courtyard buildings and six-flats fill the gaps. Most of this housing is decades old, so underwriters ask about the age of the wiring, plumbing, roof and boiler, about rear wooden porches, and whether a basement unit is finished and rented.

How a building is used decides the form. An owner who lives in a two- to four-unit building can often insure it on an owner-occupied homeowners or dwelling form that carries liability for the rental units; once the owner moves out, it becomes a landlord policy, and larger courtyard buildings move into commercial apartment building insurance. In the high-rises along the lakefront, in Streeterville and the South Loop, the association's master policy covers the structure and each owner's HO-6 picks up interior finishes, contents, liability and loss assessments. The large homes of Lincoln Park, the Gold Coast and Beverly can call for high-value home coverage.

The city has also made it easier to add units. Since April 1, 2026, Chicago's expanded additional dwelling unit ordinance allows ADUs, such as coach houses and basement or attic conversions, by right in all multi-unit residential districts and certain business districts, and in single-family districts in 34 wards. A new unit changes the occupancy, the rental income and the liability picture, so the property policy should be updated when the permit is pulled, not after the first tenant moves in. The city's ADU rules also bar using the new units as short-term rentals, so a coach house is a long-term rental or family space, not an Airbnb. The economy around all this runs on finance and professional firms in the Loop, hospitals, food processing, restaurants and a freight network of rail yards, O'Hare and the interstates.

What underwriters weigh in Chicago

Chicago's property losses tend to come from water, wind and cold rather than one big catastrophe peril. These are the exposures carriers price and ask about.

• Basement flooding and sewer backupMost of Chicago has a combined sewer system, and when it rains hard the intercepting sewers and treatment plants can be overloaded, which is why the Deep Tunnel was built. Water that comes up through a floor drain is usually excluded from a home policy unless it has a water backup endorsement, and that endorsement carries its own limit. The storms of June 29 to July 2, 2023, with the heaviest rain on July 2, flooded basements across the West Side, including Austin, and led to federal disaster declaration DR-4728 for Illinois. Rising surface or river water is a separate flood insurance question.
• Derecho and tornado windOn July 15, 2024, a derecho produced 32 tornadoes in the National Weather Service Chicago forecast area, a record for that office, with tornadoes inside the city in West Town, the Near West Side and from Chicago Lawn into West Englewood, plus straight-line winds that pushed from Oak Park into Austin. Fallen trees on roofs, garages and parked cars are the typical losses. A homeowners policy generally handles wind, and the size of the deductible decides how much of a small claim you pay yourself.
• Deep cold and frozen pipesSubzero snaps such as the polar vortex of late January 2019 split pipes in unheated rear porches, vacant units and garden apartments. Policies usually expect heat to be maintained, which matters most for buildings between tenants or under renovation, where vacant and renovation coverage may be the right form.
• Porches, stairs and tenant liabilityMulti-unit buildings mean rear wooden porches, back stairs, icy walks and a steady stream of tenants' guests. Chicago still remembers the June 29, 2003 Lincoln Park porch collapse, and carriers still ask about porch age and condition on older buildings. Landlord liability limits plus an umbrella policy carry this exposure.
• Street parking and city drivingStreet parking, theft, break-ins and dense traffic drive auto claims in the city. Comprehensive coverage is what responds to theft and vandalism, and higher liability limits on your auto policy give you more room if you are sued after a serious crash in Cook County.

Illinois and Chicago rules that matter

• Auto minimums: 25/50/20Illinois requires bodily injury liability of at least $25,000 per person and $50,000 per accident and property damage liability of at least $20,000 per accident. Illinois is an at-fault state and does not require PIP. These are state minimums; Chicago has no separate city minimum.
• Uninsured motorist on every policyUnder 215 ILCS 5/143a, an auto liability policy for a vehicle registered or principally garaged in Illinois cannot be issued or renewed without uninsured motorist bodily injury coverage at least at the state's 25/50 limits. The Department of Insurance notes that underinsured motorist coverage is required when you buy UM limits above the minimum.
• Workers' comp from the first employeeThe Illinois Workers' Compensation Commission says an employer with even one part-time employee must carry workers' compensation. Coverage comes from private insurers or Commission-approved self-insurance; Illinois has no state fund monopoly. An employer that knowingly fails to insure can be fined for every day of noncompliance and ordered to stop work until it shows proof of coverage, and corporate officers can be held personally liable if the company doesn't pay the penalty.
• Shared housing registrationEvery short-term rental unit in Chicago, meaning stays of 31 days or fewer, needs an approved City registration number before it can be listed on a platform, and registrations renew every year. Not every unit is eligible. A host approved for more than one unit also needs a Shared Housing Unit Operator License from the Department of Business Affairs and Consumer Protection.
• Contractor licenses tied to insuranceThe Department of Buildings licenses general contractors by class, from Class E up to Class A, with minimum general liability that rises with the class, from $1 million per occurrence for Class E up to $5 million per occurrence for Class A. The insurer must be authorized in Illinois and rated B+ or better by A.M. Best, and the license is automatically inactivated if the policy expires.

Insuring Chicago businesses

Chicago's small business base is restaurants, taverns, corner stores, salons, auto shops and the trades that keep old buildings standing. A restaurant or bar or nightclub usually needs liquor liability on top of property and general liability, and a neighborhood landlord with a storefront below apartments needs a mixed-use building policy rather than two mismatched ones. For a contractor, the first question is which Department of Buildings license class the work falls under, because the liability limit, the carrier rating and the proof the city wants on file all follow from it.

Rail yards, intermodal ramps and O'Hare feed a large trucking, drayage and warehousing industry across the city and the suburbs. I place intermodal and drayage coverage, box truck and commercial trucking policies, and warehouse property and cargo for Chicago operators, along with workers' comp from private carriers, since Illinois lets employers buy it in the open market.

What Chicago callers ask me about

• Basement claim denied. A finished basement or garden unit took on water through the floor drain, and the policy had no water backup endorsement or a sublimit far below the damage. I look at backup limits before the next storm, especially where tenants live below grade.
• Two-flat on the wrong form. An owner lives upstairs and rents the garden unit, but the building is insured on a form that assumes a single family, or on a landlord policy that leaves out the owner's own belongings. I match the form to how the building is actually used.
• Short-term rental without a number. A unit is listed without a City registration number, or it turns out not to be eligible, and the homeowners policy excludes paid stays anyway. Short-term rental coverage only makes sense once the unit is registered.
• Condo special assessment. A high-rise association passes a large deductible or an uninsured repair through to owners. Loss assessment coverage on the unit owner's policy can help, and the limit matters more than most owners realize.
• License about to go inactive. A general contractor's liability policy is non-renewed and the city license will lapse with it. I find replacement general liability at the limit the license class requires before the expiration date.
