5111 N Nagle Ave
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.
This building has 0 building violations (7y), at or below the Jefferson Park average of 0.4.
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 two-unit residential building at 5111 N Nagle Ave in the Jefferson Park neighborhood, owned by Nicholas Kopsian, has experienced several notable service issues over the past several years. Most concerning are the series of water-related problems in spring 2026, which included multiple complaints about water service interruptions and water presence on the street - suggesting infrastructure challenges that impacted resident access to this basic utility. The property has also documented other maintenance and safety issues, including a street light outage in November 2025 and a leak check request in March 2025, both of which were addressed by city services and marked as closed. While the building's registered complaints total 12 over the past seven years, it's worth noting that there has only been one building permit filed during this period, which may indicate limited recent structural modifications or improvements. The most recent recorded incident was a graffiti removal request from May 2026, though the impact of this particular issue on resident quality of life is arguably minimal compared to the water-related concerns.

How 5111 N Nagle 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
