Augrented Insights Report for 497 St Marks Avenue

The 8-story, 147-unit building at 497 St. Marks Avenue in Crown Heights, owned by Yosi Cohen and completed in 2014, has experienced persistent maintenance issues, particularly relating to mold and building systems. Most notably, from 2024 through 2025, there have been multiple complaints and violations concerning unsanitary mold conditions, with the most recent reports of mold problems occurring as recently as June 2025.

The building has also faced problems with building systems, including a significant power outage in September 2024, fire escape safety concerns, and various door/window issues for which violations were issued. Apartment 1A has shown particular recurring maintenance needs, with violations documented between 2022-2024 regarding mold, wall conditions, and door repairs. The building's infrastructure has been a recurring source of concerns, with several Department of Buildings complaints and violations related to the elevator systems, boiler, and ventilation.

In late 2023, the building faced complaints regarding ventilation and exhaust systems, leading to an Oath violation. There have been three outstanding Environmental Control Board violations from January 2022 regarding ventilation issues that remain active, with associated penalties. While the building has maintained a clean record for bedbugs, with no reported infestations from 2020-2025, and has consistently passed rodent inspections, the persistent mold issues and infrastructure concerns suggest ongoing maintenance challenges. The property has demonstrated compliance with many HPD inspections, as violations generally get addressed, though initial inspection attempts to access some units have required follow-up inspections.
