Unlock complete reportThe two-building service requests filed with the City of Chicago in 2025 for 4907 W Patterson Ave in the Portage Park neighborhood appear to be unrelated to the building's residential conditions or management, as they concerned municipal issues outside the property's direct control. These included a water-on-street situation reported in September and an abandoned vehicle complaint made in May, both of which were subsequently closed. The property, which consists of six units and was constructed in 1924, is currently under the ownership of Authority Real Estate. Over the past seven years, there have been only two service requests and two building permits recorded for this address, suggesting relatively minimal interaction with city services. The building's permit and complaint history shows no significant pattern of maintenance issues or resident concerns, though it's worth noting that the time frame for the records provided (up to October 2023) means there could be more recent developments not captured in this analysis.

How 4907 W Patterson 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.
Out of 3924 buildings in this neighborhood, 2511 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
