6253 W Patterson Ave
Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.
This building has 0 building violations (7y), at or below the Dunning average of 0.8.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe two-unit residential building at 6253 W Patterson Ave in Chicago's Dunning neighborhood is a 1929 structure currently owned by Jose D Zavala. Over the past seven years, the property has accumulated a total of 12 service requests through the 311 system, with the most recent cluster of activities occurring in 2025-2026. The property currently shows two open requests as of October 2023: one for sidewalk inspection initiated in May 2026, and another for tree planting initiated in September 2025. The winter of 2025-2026 appears to have been a particularly active period for service requests, with completed actions including a recycling pick-up and a missed garbage pick-up complaint in March 2026, as well as a closed request for garbage cart maintenance in December 2025. Given the nature of these requests, which primarily relate to external maintenance and city services, it appears the building has been maintaining compliance with basic municipal requirements, though the frequency of recent service requests may indicate ongoing engagement with city services for various maintenance matters.

How 6253 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 1070 buildings in this neighborhood, 888 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
