4040 S Montgomery 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 Brighton Park 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 three-unit, 1918 brick building at 4040 S Montgomery Ave in Brighton Park has had minimal documented activity over the past seven years, with the property record showing only two 311 service requests and two building permits during this period. The most recent 311 service request, filed in June 2026, concerns an abandoned vehicle complaint and remains open as of the latest data. Prior to this, there was one closed service request from July 2024 regarding a tree trim, though this type of request is no longer being accepted. The building permits on record show no recent modifications or improvements to the property, and no complaints or violations have been recorded in the available data. The limited number of service requests and permits over this extended period could suggest either careful maintenance practices or potentially indicate areas requiring attention, though no specific issues have been documented through official channels.

How 4040 S Montgomery 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 3962 buildings in this neighborhood, 3170 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
