Brighton Park, Chicago IL 60632 19011310380000 3 units · 1940

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.

Initial analysis

The three-unit residential building at 4256 S Mozart Street in Brighton Park, owned by Vincent Tellez, has been standing since 1940 and has experienced minimal documented activity over the past seven years. The property has generated a total of 11 service requests by the owner, with only one building permit and two minor violations recorded during this period. The most recent and only building-related service request occurred in April 2026, concerning an alley pothole, which remains open as of the report date. Prior to this, between October 2025 and February 2026, there were three street pothole complaints, an abandoned vehicle report, and one general information call to 311, all of which have been resolved. It's important to note that these recent roadway-related issues appear to be infrastructure concerns affecting the broader area rather than problems specific to the building itself. The relative scarcity of building permits and violations over this extended period could suggest either careful maintenance or minimal record-keeping; however, no recent major renovations or improvements are documented in the permitted work history.

Risk rating

How 4256 S Mozart St'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.

Neighborhood percentile
9thpercentile

Out of 3962 buildings in this neighborhood, 3605 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
