Unlock complete reportThe two-unit residential building at 4528 N Karlov Ave in Albany Park, owned by Luis Lema, is a 130-year-old structure built in 1893. The property's recent history (dating back seven years) shows some concerns that warrant attention, particularly two unresolved building code violations from 2019 and 2022, which fall under complaint-driven and permit-related inspection categories, respectively. The most recent incident involving the property was a nuisance animal complaint filed in April 2024, though this matter has already been resolved. While the building hasn't accrued a large number of violations or service requests, the presence of two open code violations from previous years is notable, as is the age of the structure which typically requires ongoing maintenance and supervision. The relatively low number of service requests and violations in the past seven years could suggest reasonable building management practices, though the unresolved nature of the recent code violations raises some concerns about prompt attention to regulatory requirements.

How 4528 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.

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
