Unlock complete reportThe three-unit residential building at 1825 N Karlov Ave in the Hermosa neighborhood, owned by Lydia Maestre, has been standing since 1904 and has experienced several notable events over the past seven years. Most significantly, in February 2020, the building underwent a series of complaint-driven inspections that resulted in six code violations, though all of these were subsequently resolved. The property has maintained an active response record with five 311 service requests in recent years, with the most recent being a tree trim request in September 2025. The building has faced recurring rodent issues, with two rat complaints filed in May 2024 and one in August 2024. Additionally, there were maintenance-related requests for garbage cart services and blue recycling cart issues in April and May 2024 respectively. While the building has had some challenges, particularly with pest management and waste disposal matters, it's worth noting that all recorded building code violations have been resolved and only one building permit has been issued in the past seven years.

How 1825 N 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
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 1618 buildings in this neighborhood, 1586 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
