Unlock complete reportThe Wellington Flats, a four-unit residential building located at 621 W Wellington Ave in Chicago's Lake View neighborhood, has experienced several notable incidents over the past three years (2025-2026) that warrant attention. The 128-year-old property, currently owned by Wellington Flats LLC, is facing multiple open issues as of 2026, including a water lead test kit request, a building violation, and a construction-related violation regarding lack of proper permits. These open violations, particularly the water lead test request, could potentially impact resident safety and quality of life. The building's service request history also reveals some attention to property maintenance and community services, with three closed requests in 2026 (g garbage cart maintenance), 2025 (tree planting), and 2025 (dead animal pick-up), though these generally indicate routine municipal interactions rather than significant building issues. The property has generated a total of 12 service requests across two parcels in the past seven years, though most of these were not specified in the available records. The concentration of open violations and service requests in 2025-2026 suggests current challenges in property maintenance and compliance with local regulations.

How 621 W Wellington 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 3452 buildings in this neighborhood, 2175 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
