Unlock complete reportThe two-unit residential building at 1521 E 73rd Street in Chicago's South Shore neighborhood, owned by Lori Foster, is a 126-year-old structure dating back to 1897. The property has experienced several notable service requests in recent years, with the most significant cluster occurring in mid-2025 when three separate complaints regarding water in the basement were filed within a one-week period, followed by a fourth basement water complaint shortly thereafter. These recurring moisture issues appear to be a persistent problem, particularly as they were immediately preceded by a tree debris clean-up request in July 2025. Additionally, there was an abandoned vehicle complaint recorded in December 2025, though this is unrelated to the building's direct conditions. As of September 2023, there is an open request regarding the inspection of the public way adjacent to the property. The building's 311 service request history over the past seven years consists of 12 recorded incidents, which, while not excessive for a property of its age, suggests some ongoing maintenance challenges, particularly related to water management.

How 1521 E 73Rd 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 2804 buildings in this neighborhood, 1009 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
