434 W Diversey Chicago
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.
This building has 0 building violations (7y), at or below the Lake View average of 1.0.
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 9-unit building at 434 W Diversey in Chicago's Lake View neighborhood has been under the ownership of Planned Partnerships since its construction in 1909. The property has experienced significant regulatory activity over the past seven years, with an alarming total of 110 building violations recorded, in addition to 10 house share violations. While there have been some building permits issued (6 in total), this represents a relatively low level of permitted improvements compared to the size of the property and the number of violations on record. The building has also generated a substantial number of service requests, totaling 181 over the seven-year period, though recent months have shown a marked increase in restaurant-related complaints, with three such complaints filed between June and August 2025. Other recent service requests include two information-only calls to 311 City Services (in September 2025 and January 2026) and a tree trim request filed in June 2025. Given the building's age and the high number of violations on record, the property appears to be experiencing ongoing maintenance and regulatory challenges, though the most recent service requests have primarily concerned matters outside the building itself, such as tree maintenance and restaurant complaints.

How 434 W Diversey 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.
Out of 3452 buildings in this neighborhood, 3072 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
