Augrented Insights Report for 523 Dean Street

The 4-story, 8-unit building at 523 Dean Street in Prospect Heights, owned by Vernetta Nelson, has experienced numerous maintenance challenges in recent years. Most notably, between October 2023 and December 2023, there were multiple complaints about heat and hot water issues, with residents reporting problems in both individual apartments and throughout the entire building.

December 2023 brought a cluster of complaints that HPD was unable to inspect, including issues with an electric/gas range, cabinets, slow water leaks, flooring, electrical lighting, and pest-related unsanitary conditions. The building has been under the Department of Buildings scrutiny as well, with an active violation from June 2023 regarding the failure to file the 2018 External Low Pressure Inspection.

The property has a concerning history of maintenance violations, particularly affecting Apartment 4R, which has open violations as of April 2023 for various repairs needed including a broken bathtub, defective cabinets, and door lock issues. While bedbug inspections from 2019 to 2024 show no reported infestations, and rodent inspections from 2017-2018 indicated both passed inspections and the application of bait, the building continues to struggle with basic maintenance issues. Heating system problems appear to be a recurring theme, with multiple emergency complaints about heat and hot water continuing into 2023, suggesting persistent infrastructure challenges that affect resident comfort and safety.
