Unlock complete reportThe Keystone Courts building at 4315 N Keystone in Chicago's Irving Park neighborhood is a 61-unit residential property constructed in 1922 and currently owned by Keystone Courts LLC. The building's recent history, particularly over the past two years, shows a concentration of activity in August 2021 when six complaint-driven inspections and one periodic routine inspection occurred, though all these violations have been resolved. The property has maintained a relatively stable record over the past seven years, with a total of 12 building violations and 21 service requests, though these figures suggest some recurring maintenance and compliance issues. Most notably, there has been a recent spike in exterior infrastructure concerns, with multiple pothole complaints (at least four) reported in April 2026, all of which have been closed. These street maintenance issues, while not directly related to the building's internal conditions, may affect resident access and transportation convenience. The building's permit activity is limited, with only two permits recorded in the past seven years, though this is not uncommon for older residential buildings requiring minimal structural changes.

How 4315 N Keystone Chicago'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 3731 buildings in this neighborhood, 3731 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
