Unlock complete reportThe six-unit residential building at 1251 W Columbia Ave in Rogers Park, owned by Peter M Nicholas, has experienced several significant issues over the past seven years. Most notably, there are three unresolved code violations recorded on August 4, 2022, following a complaint-driven inspection that warrant attention due to their open status. The building's maintenance history shows a series of service requests between 2025-2026, including two rodent-related complaints in July 2025 (one through the Alderman's office and one through 311 City Services), and a water lead test kit request in July 2025, suggesting potential concerns about water quality. The property also experienced infrastructure issues with two pothole complaints on the street in early 2026. While all these service requests have been closed, the presence of multiple complaints about rodents and unresolved building code violations indicates some ongoing challenges with building maintenance and environmental conditions, though the closed status of most recent complaints suggests these issues may have been addressed. The building, constructed in 1912, is currently listed with three building code violations and eight service requests over the past seven years, which is consistent with its age and historical context.

How 1251 W Columbia 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.
Out of 1536 buildings in this neighborhood, 1075 are predicted to be safer.
