Unlock complete reportThe two-unit building at 3831 S Winchester Ave in McKinley Park, owned by Douglas Johnson, has been on record since its construction in 1929. The property's documented history over the past seven years shows limited recent activity, with only three 311 service requests filed in 2025, including a water in the basement complaint, a no-longer-accepted tree trim request, and a building violation, all of which have been closed. The building's permit activity during this period is minimal, with only two building permits issued plus an additional permit under the owner's name that covers two parcels. The property has a total of 22 service requests on record under the owner's name, though these are not all necessarily related to the building itself, as they span multiple parcels. Given the property's age and recent water-related issues, as evidenced by the basement complaint, this building's record warrants attention, though the limited number of service requests and permits over the past seven years could also suggest relative stability in other aspects of building maintenance and operations.

How 3831 S Winchester 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 1411 buildings in this neighborhood, 240 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
