Initial analysis

The two-unit residential building at 4219 W Leland Ave in Chicago's Albany Park neighborhood, owned by Walter Wayne Theefs and constructed in 1924, has experienced several notable issues over the past two years. Most concerning is a cluster of rodent-related complaints, with three separate rat-related incidents reported between April 2024 and September 2025, suggesting an ongoing pest control challenge in the vicinity. The building's service history also includes two tree planting requests (April 2024 and September 2025) and one street cleaning request (September 2025), all of which were appropriately closed following service fulfillment. While the property shows some engagement with municipal services through these requests, the frequency of rodent complaints stands out as the most significant pattern in the building's recent history. It's worth noting that only one building permit has been recorded in the past seven years, though this information pertains only to the permit that was applied for and may not accurately reflect the property's current conditions or any recent improvements.

Risk rating

How 4219 W Leland 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.
