423 E Ohio Chicago

Streeterville, Chicago IL 60611 17102110310000 50 units · 2015

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 50-unit residential building at 423 E Ohio in Streeterville, owned by 423 E Ohio LLC Golub, was constructed in 2015 and has maintained a relatively low incident record over its first seven years of operation. The property has experienced only four documented 311 service requests during this period, all of which were recorded and closed in early 2025. These requests were primarily related to sign maintenance issues, with three of the four specifically addressing sign repairs, including work completed in February and July of that year. The sole remaining service request from March 2025 concerned graffiti removal. Notably, these sign-related issues appeared in quick succession, with three requests for sign repairs clustered within approximately one month (February 2025) before the pattern shifted to the July request. The building's permit activity is minimal, with only one building permit filed in the past seven years, though the specific nature and outcome of this permit is not detailed in the provided data.

Risk rating

How 423 E Ohio Chicago'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
81stpercentile

Out of 27 buildings in this neighborhood, 5 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
