6431 N California 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 West Ridge average of 1.2.
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 6-unit residential building at 6431 N California Ave, located in Chicago's West Ridge neighborhood, was constructed in 1927 and is currently owned by Alexandru Filimon. Over the past seven years, the property has experienced 38 building violations and 36 service requests through the 311 system, indicating a relatively high level of maintenance issues. Between 2025 and 2026 alone, there have been multiple service requests, including two open cases related to sidewalk conditions (a Shared Cost Sidewalk Program Request in January 2026 and a Sidewalk Inspection Request in September 2025), suggesting ongoing concerns about pedestrian infrastructure around the property. Other recent service requests have included reports of street light pole damage, business complaints, and parking code enforcement reviews, though most of these issues have been resolved (marked as closed). It's worth noting that the building's violation and service request records cover a wide range of issues, though the specific nature of these violations is not detailed in the available data. A historical air pollution complaint from 1994 is on record, but this appears to be an isolated incident from many years ago.

How 6431 N California 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 3126 buildings in this neighborhood, 2563 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
