Augrented Insights Report for 641 St Marks Avenue

641 St Marks Avenue is a four-story, 30-unit residential building located in Crown Heights, built in 1900 and currently owned by Prospect Heights 637-641 Realty LLC. The property has experienced several significant maintenance issues in recent years, with particular concern for rodent infestations emerging as a recurring problem, with multiple rat sightings documented in 2025 and ongoing baiting efforts continuing into July 2025.

The building has also faced various safety and maintenance challenges, including fire escape violations (April 2025), multiple general maintenance complaints in April 2025 (including issues with signage, roof access, pavement, water damage, and various other conditions), and emergency complaints regarding heat and hot water systems in June 2025. The building's history shows persistent maintenance challenges, with violations previously issued in 2024 related to life safety systems, including faulty smoke and carbon monoxide detectors in Apartment 4D.

Other notable violations include concerns about the building's exterior, with inspections revealing issues such as cracked roof soffits, loose bricks, and problems with the sidewalk shed structure. The property has also faced regulatory scrutiny regarding its boiler system and building access points, with multiple Department of Buildings (DOB) violations issued from 2024 through 2025, including issues with electrical wiring, water damage, and various construction-related concerns. While there have been no documented bedbug infestations in recent years (with annual reporting showing zero affected units), the building's maintenance history indicates ongoing challenges with both basic building systems and pest control, particularly regarding rodent management as evidenced by the frequency of rodent-related service requests and inspections through 2025.
