Unlock complete reportThe two-unit residential building at 3710 N Olcott Ave in Chicago's Dunning neighborhood, currently owned by Carlos Diaz, has been recorded as having relatively minimal issues over the past seven years. The 1923 structure has generated a total of 37 311 service requests during this period, with the most recent documented incidents occurring in 2025 and consisting primarily of routine municipal service requests including street light outages, a garbage cart maintenance issue, and an abandoned vehicle complaint. Notably, there is one building violation on record for the owner during this seven-year span, though the specific nature and resolution of this violation are not detailed in the available data. The property has also generated one building permit request in the same timeframe. The most immediate concern for the property appears to be the ongoing shared cost sidewalk program request initiated in January 2025, which remains open as of the most recent data update. While the frequency of service requests seems to suggest some level of maintenance activity, most issues reported have been external to the building itself, focusing on public infrastructure and services rather than building-specific concerns.

How 3710 N Olcott 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, 663 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
