Lincoln Square, Chicago IL 60625 13122200380000 2 units · 1949

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 two-unit building at 2620 W Summerdale Ave in Lincoln Square, owned by Angelo Demetrakakis, was constructed in 1949 and has generated a total of 10 311 service requests over the past seven years. The most recent activities, dating from April 2026, include two notable public infrastructure concerns: a sewer cave-in inspection request and an abandoned vehicle complaint, both of which have been closed. The property has experienced recurring issues with street signage, with two open sign repair requests recorded in 2025 (one from April and another from August). Other service requests in 2025 include a closed animal in trap complaint (May) and a closed abandoned vehicle complaint (July). While the building's overall 311 request frequency appears moderate for its age and location, particular attention may be warranted regarding the open sign repair issues and the relatively recent occurrence of sewer-related concerns.

Risk rating

How 2620 W Summerdale 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.

Neighborhood percentile
25thpercentile
