AI summary

The four-unit residential building at 3321 N Pontiac Ave in the Dunning neighborhood, owned by Bernard Stark, has a relatively low volume of service requests considering its age (built in 1922). Over the past seven years, there have been 11 reported service requests, with the most recent cluster of issues emerging in 2025. Notably, there are three open requests from 2025: a water lead test kit request, a tree planting request, and a tree emergency (reported through the Alderman's office). The building has also experienced some maintenance concerns, as evidenced by a leak check request filed in January 2025, though this case has since been closed. Earlier in 2025, there were two separate requests regarding blue recycling carts, both of which have been resolved. The relatively small number of complaints over this extended period suggests stable building management, though the presence of multiple open requests in 2025 warrants attention to resolution progress.

Risk rating

How 3321 N Pontiac 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

Grade A–B — Low risk

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
