Initial analysis

The two-unit residential building at 1837 N Karlov Ave 1 in Hermosa, owned by Lydia E Maestre, has been operational since 1915 and has generated a total of 10 service requests through the 311 system over the past seven years. The property has experienced recurring issues this year, particularly with rodent problems, as evidenced by three separate rodent baiting complaints between May and September 2025. Additionally, there have been multiple requests for garbage cart maintenance, with two recorded in September 2025 alone, along with one tree debris clean-up request in August 2025. While all reported service requests have been closed, the frequency and nature of these issues, particularly the persistent rodent-related complaints, suggest ongoing challenges with waste management and pest control in the vicinity.

Risk rating

How 1837 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

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.
