Unlock complete reportThe 4300 N Mozart St 1st Floor property in Chicago's Irving Park neighborhood is a three-unit building constructed in 1964, currently owned by BTRE 2 INVESTMENTS LLC. The building's recent maintenance and service history shows a total of 48 service requests through the 311 system over the past seven years, with 11 building violations recorded during the same period. The most recent service requests between March and April 2026 primarily relate to municipal services, including a missed garbage pick-up and street light outage, while the summer of 2025 saw multiple tree-related service requests, including two tree planting requests and two tree emergencies, with one emergency request remaining open as of August 2025. The property has been subject to three building permits in the past seven years, though specific details about the nature of these permits are not provided in the available data. While the building has experienced several municipal service issues typical of urban properties, the frequency and nature of these requests suggest ongoing engagement with city services for both routine maintenance and emergency situations.

How 4300 N Mozart St 1Stfl's risk score is calculated
