Unlock complete reportThe property at 20 North Throop Street is a two-unit building located in Chicago's West Loop neighborhood, constructed in 1890 and currently owned by 20 North Throop LLC. The building's service request history over the past seven years shows a total of 16 recorded incidents, with the most recent requests occurring in 2025-2026. Notable recent issues include an open tree emergency reported in June 2026 and a water lead test kit request from November 2025 that remains unresolved. The property has also experienced wildlife-related concerns, with a coyote interaction complaint filed in February 2026, though this was subsequently closed. Other service requests have included routine maintenance matters such as tree debris clean-up in December 2025, blue recycling cart services, and garbage cart maintenance, all of which were successfully closed. While many of the service requests pertain to standard municipal services, the two open requests related to tree issues and water testing may warrant particular attention from a resident safety perspective.

How 20 N Throop St's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 205 buildings in this neighborhood, 23 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
