Augrented Insights Report for 509 Dean Street

509 Dean Street is a 4-story, 8-unit residential building constructed in 1930, currently owned by Oron Tanami. The property has experienced several significant issues in recent years that may impact resident safety and comfort. Most concerning is an active violation from February 2025 regarding disconnected steel steps on the rear fire escape between the 1st and 2nd floors, and approximately 30-foot-long crack observed at the right corner of the building.

The building is also under structural monitoring as of March 2025. Multiple violations related to external low-pressure inspections remain active from 2018 through 2024, indicating possible ongoing maintenance compliance issues. While the building has maintained an active bedbug reporting history showing zero infestations from 2021 through mid-2025, there were several years with documented fire escape access issues, including a 2018 violation for a defective drop ladder and obstruction by garbage cans.

The building's maintenance history shows periodic struggles with rodent control between 2017 and 2018, with multiple rat activity reports followed by successful compliance inspections. Two unsanitary condition complaints regarding garbage/recycling storage were filed in October 2019, though no violations were issued following inspections. The property has consistently filed timely bedbug reports over the past four years, indicating good compliance with this particular requirement. While earlier violations (2018) regarding fire escape access were resolved, the most pressing current concerns involve the building's structural integrity and fire safety equipment maintenance.
