Unlock complete reportThe three-unit residential building at 3404 N Karlov Ave in Chicago's Irving Park neighborhood, owned by Pablo & Mergedes Pepin, has been standing since 1909 and has generated a small number of service requests over the past seven years. The property has experienced several notable maintenance and quality-of-life issues in recent years, with the most recent incidents occurring in May 2026, including complaints about rodent activity and a city vehicle sticker violation. Shortly before these incidents, there were also concerns about nuisance animals (March 2026) and an apparent graffiti problem, with two separate removal requests filed in November 2025. The combination of rodent complaints and animal nuisance reports suggests ongoing challenges with pest control and maintenance in and around the building. While all five service requests have been officially closed, the frequency of these incidents over the past two years indicates some ongoing concerns about the property's management and maintenance conditions.

How 3404 N Karlov Ave 1'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, 1820 are predicted to be safer.
