Chicago Two-Flat and Three-Flat Property Tax Appeals: Combining Uniformity and Income

Owners of Chicago two-flats and three-flats occupy a useful middle ground in the property tax system, and understanding it is the key to a successful appeal. Buildings of six units or fewer are assessed as residential property at 10 percent of market value, the same ratio as a single-family home, rather than at the 25 percent commercial ratio. That residential treatment, combined with the income these buildings produce, creates specific appeal opportunities that single-family owners do not have.

The City of Chicago is its own triennial reassessment group, so two-flat and three-flat owners should know their reassessment year and file then, as well as in other years when their assessment appears high.

How the appeal works for small multi-unit buildings

Appeals go first to the Cook County Assessor and then to the Cook County Board of Review, each opening the relevant city township for about 30 days on its own schedule. The first step is confirming the township in which the building sits.

Uniformity and income, together

Two-flats and three-flats can be appealed on two grounds. The first is uniformity, comparing the building's assessment to comparable two-flats and three-flats nearby. The second, available because these buildings produce rent, draws on the income the building generates. While small residential income properties are assessed primarily on market value rather than a full income approach, documented rents and expenses can support an argument that the Assessor's market value is too high, particularly for a building with below-market rents, high vacancy, or significant deferred maintenance.

Condition and deferred maintenance

Many of Chicago's two-flats and three-flats are older buildings, and condition varies widely. A building with an aging roof, outdated systems, or deferred maintenance is worth less than a renovated building of the same size, and the Assessor's model may not capture that difference. Documenting condition, with photographs and repair estimates, supports a lower valuation.

Two-flat and three-flat owners benefit from appeals that combine uniformity with the building's real income and condition, which is more involved than a single-family appeal.
