Unlock complete reportThe three-unit residential building at 1020 W 20th Place in Chicago's Lower West Side, owned by Christopher W Mueller, has maintained a relatively clean housing record since its construction in 1886. Over the past seven years, there have been only two documented 311 service requests associated with the property, both of which were addressed and closed by the city. The most recent request, filed in January 2026, pertained to snow-related parking issues, specifically regarding object/dibs removal. Prior to that, in August 2025, there was a request related to finance parking code enforcement that required city review. Both incidents appear to be routine winter parking matters rather than substantive building or maintenance issues, suggesting that the property has experienced minimal official complaints or notable incidents during this period.

How 1020 W 20Th Pl 2Nd'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, 1731 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
