Initial analysis

The two-unit residential property at 3521 N Keating Ave in Portage Park, owned by John Nealis, has been actively monitored over the past seven years, with 89 service requests recorded through the 311 system. The 1908 building has experienced notable recent activity, particularly in June 2026, with six consecutive Finance Parking Code Enforcement Review requests filed between May 30 and June 9, all of which have been closed. This cluster of parking-related complaints represents the most significant recent pattern of incidents associated with the property. Looking at the broader history, the building has accumulated a total of 18 violations over the past seven years, though specific nature and resolutions of these violations are not detailed in the available records. Permit activity has been relatively low, with only two permits issued to the owner during this period, suggesting limited recent construction or modification work. The building's total parcel ownership is recorded as five, indicating the owner holds additional property interests beyond the main building location. The age of the building and the total number of service requests and violations, while notable, should be viewed in the context of its long-standing history in the neighborhood.

Risk rating

How 3521 N Keating 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

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.
