Unlock complete reportThe three-unit building at 1637 W North Ave in Wicker Park, owned by Richard Chayygoa, has experienced a concerning pattern of issues over the past several years. The 132-year-old property has accumulated 30 building code violations in the past seven years, with the most recent violations recorded in March 2024 and multiple unresolved routine inspection violations from November 2023. Notably, there appears to be a significant ongoing issue with water management, as evidenced by multiple 311 service requests in early 2026, including two basement water complaints and a plumbing violation, all of which have either been closed or are in the process of being addressed. The property has also undergone three periodic routine inspections since 2023 that have resulted in open violations, as well as two complaint-driven inspections in 2022 with unresolved violations. While there have been some building permits issued in the same timeframe, their limited number (only two) in relation to the frequency of violations suggests minimal proactive maintenance or improvements. The most recent services requested by the city have included a water lead test kit request, indicating possible concerns about water quality that may require attention.

How 1637 W North 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 1722 buildings in this neighborhood, 1567 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
