Unlock complete reportThe three-unit residential building at 1431 S Karlov Ave in North Lawndale, owned by Willie Chinn, has experienced a concerning pattern of unresolved building code violations and service requests over the past seven years. Most notably, there are currently five open unresolved building code violations as of October 2023, with complain-driven inspections recorded in both 2023 and 2024. Additionally, the property has accumulated a significant number of building violations during this period, totaling 17, which is particularly notable for a three-unit structure built in 1926. The building's service history also raises concerns, with two plumbing-related issues (including a no-water complaint) recorded in May 2026, though one of these was subsequently closed. The property has also had multiple reports of injured animals (three separate incidents between 2025 and 2026) and a weed removal request in September 2025, all of which were closed. The limited activity in terms of building permits during this period, with only one permit recorded, contrasts sharply with the high number of violations and service requests, suggesting potential maintenance and oversight challenges.

How 1431 S Karlov 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
