1634 N Mozart St
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 Humboldt Park average of 1.2.
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 residential building at 1634 N Mozart St in Humboldt Park, owned by Pedro Guerrero, is an 1888 construction that has experienced consistently active maintenance and response needs over the past seven years. The property has generated a total of 31 service requests through the 311 system during this period, with the most recent cluster of incidents occurring in 2026, including multiple tree-related emergencies in June 2026 (three reports, with one still open), a street light pole damage complaint in May 2026, a vacant lot cleaning request, and a rodent-related issue in early May 2026 - all of which have been resolved. While these recent issues may suggest ongoing environmental management challenges in the vicinity, it's notable that the building has no recorded complaints regarding building-specific issues such as air quality or internal maintenance in either the 311 service request data or the more historical records, which includes only one environmental complaint from 2000 related to air pollution that did not specify a direct connection to this property. The documented service requests primarily relate to external infrastructure and environmental concerns typical of the neighborhood rather than building-specific problems.

How 1634 N 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.
Out of 6229 buildings in this neighborhood, 5544 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
