Initial analysis

The three-unit residential building at 4236 W Crystal St in Humboldt Park, owned by Detongress Grayer, was constructed in 1920 and has had minimal documented issues in recent years. The property has generated three 311 service requests over the past seven years, with all incidents occurring between April 2024 and April 2025. These service requests include a fly dumping complaint in April 2025, a yard waste pick-up request in October 2024, and an abandoned vehicle complaint in April 2024, all of which were closed following proper resolution procedures. The limited number of service requests and their nature—primarily relating to external property management issues rather than building-specific concerns—suggests the property has experienced relatively few significant concerns requiring municipal intervention.

Risk rating

How 4236 W Crystal St'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.
