Unlock complete reportThe two-unit residential building at 8639 S Houston Ave in South Chicago, owned by Hector & Norma Tamayo, has a documented history dating back to its construction in 1900. Over the past seven years, the property has experienced a notable number of building violations, totaling 33, with the majority of these occurring during a specific cluster of complaint-driven inspections on February 13, 2020. These six violations from that date, however, were all resolved and marked as complied. The building's most recent documented service request was submitted on August 19, 2025, regarding a tree emergency and was subsequently closed, though this is a matter typically unrelated to the building's habitability or safety conditions. While the total number of building violations appears high at first glance, it's worth noting that all the specific violations from 2020 were addressed and resolved, and there have been no documented violations or service requests in the past three years, suggesting an absence of recent regulatory concerns.
How 8639 S Houston Ave 1St'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 2603 buildings in this neighborhood, 2369 are predicted to be safer.
