Unlock complete reportThe five-unit residential building at 2020 N Keystone Ave in the Hermosa neighborhood, owned by RTS PROP LLC, has been part of the Chicago real estate landscape since 1924. The property's recent maintenance history, as documented through 311 service requests, shows relatively few incidents over the past years, with only two service requests recorded in the past year and a half: an alley light outage in May 2025 and a dead animal pickup request in October 2024, both of which were promptly closed. The building's overall 311 service request record from the past seven years shows only two complaints related directly to the property itself, suggesting minimal resident-initiated service calls. However, the building has experienced some regulatory challenges, with records indicating one house share prohibition violation in the past seven years. In a broader context, the property owner, RTS PROP LLC, has a total of 16 service requests on record across its three parcels, with four violations of house share regulations, though it's worth noting that these totals include multiple properties and do not necessarily reflect conditions at the Keystone Avenue building specifically.

How 2020 N Keystone Ave'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 1617 buildings in this neighborhood, 631 are predicted to be safer.
