Initial analysis

The four-unit residential building at 3713 W Belmont Ave in Chicago's Avondale neighborhood, owned by Janusz Czosnyka, has been in operation since 1916 and has had relatively few reported issues over the past seven years. The property's 311 service request record shows a total of seven documented incidents, with the most recent being an open request from May 2026 regarding debris removal from a protected bike lane. There are currently two open requests that remain unresolved: one from August 2024 concerning sidewalk inspection and another from March 2026 regarding alley potholes, though the latter had been marked as closed in error. The building has experienced periodic issues with graffiti, with two removal requests filed in 2024 and 2025, both of which were successfully closed. Other service requests included a closed wire basket request from August 2025. The relatively low number of complaints and the successful resolution of most issues suggests routine maintenance practices, though the open requests regarding sidewalk conditions and bike lane maintenance may warrant attention.

Risk rating

How 3713 W Belmont 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.
