Unlock complete reportThe three-unit, three-parcel building at 4136 N Ridgeway Ave in Chicago's Irving Park neighborhood, constructed in 1902, is currently owned by Mario Lopez. The property has generated a total of 10 service requests over the past seven years, with the most significant and recent issues occurring in June 2026. Three separate tree-related emergencies were reported during this period, along with a tree debris clean-up request and a tree removal inspection in March 2026, all of which remain open and could potentially impact resident safety and environment. While there have been other service requests including a blue recycling cart request and a closed nuisance animal complaint in earlier months of 2026, the current focus appears to be predominantly on tree-related issues. The building's 311 service request record shows relatively few incidents for a structure of its age and size, though the concentration of recent tree-related emergencies warrants attention.

How 4136 N Ridgeway 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.
Out of 3714 buildings in this neighborhood, 2154 are predicted to be safer.
