Unlock complete reportThe four-unit residential building at 900 W 20th Place in Chicago's Lower West Side, constructed in 1887, has experienced several notable incidents and ongoing issues over the past several years. Most recently, in June 2026, there have been complaints about fly dumping and water on the street, both of which remain open. The property has faced recurring water-related issues, with at least three street water complaints recorded between 2025 and 2026, as well as a sewer cleaning inspection request in 2025. Of particular concern are the five documented air pollution complaints during the summer of 2023, with three of these being validated and requiring resolution, while two were found to have no violations. Earlier infrastructure issues were also noted, including a street light outage and an open fire hydrant complaint in 2024, both of which were resolved. The building's owner, registered as 2012 18 S Peoria RRCBM, has had minimal documented interactions with city services, with seven total 311 service requests and five environmental complaints recorded over the past seven years, with the majority of recent issues centering around water-related and air quality concerns.

How 900 W 20Th Pl'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 3683 buildings in this neighborhood, 2541 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
