Unlock complete reportThe two-unit residential building at 1818 W 21st Place in Chicago's Lower West Side, owned by Coty E Corcoles, has experienced a cluster of concerning water and sewer-related issues in recent years. Since September 2025, there has been a notable pattern of infrastructure problems, with multiple open service requests related to sewer inspections and water issues. Specifically, there are three open alley sewer inspection requests (as of June 2026) and one open water on street complaint from October 2025, suggesting potential ongoing challenges with the property's wastewater management systems. Prior to these, there were two other water-related incidents in late 2025, including a low water pressure complaint and a sewer cleaning inspection request, though these particular cases have been marked as closed. The building, constructed in 1888, and its surrounding infrastructure appear to be facing persistent plumbing and drainage concerns, with seven total 311 service requests registered under the owner's name in the past seven years, all of which have been water or sewer system related, though records only show multiple instances of the same type of requests.

How 1818 W 21St 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, 994 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
