Augrented Insights Report for 634 Decatur Street

634 Decatur Street is a three-story, three-unit old-law tenement building located in Bedford-Stuyvesant and owned by Robert Silverblatt. Built in 1899, the property has experienced several maintenance issues over recent years, particularly during late 2021 when multiple complaints were filed regarding water leaks, window problems, electrical issues, and unsanitary conditions including mold and sewage. During this period, violations were recorded for specific water leaks, window frame, and window pane issues, though many complaints were ultimately closed without violations. The building has also had documented sewage odor problems in late 2021, rodent sightings in 2022, and a series of bedbug reporting requirements from 2021 to 2023, with the most recent reports showing no infestations or eradications.

More recent history shows improved conditions, with rodent inspections conducted from 2022 to 2025 consistently passing, except for one instance in April 2022 where rat activity was noted. The building has maintained compliance with bedbug reporting requirements since 2022, showing zero infested or eradicated units in recent years. Notable violations currently open from November 2021 include infestations of mice and roaches, and water leak issues specifically in Apartment 1. The most recent building inspection in March 2023 noted an annual bedbug report violation, though this appears to have been resolved based on subsequent filings.

Recent complaints about illegal conversion from December 2021 resulted in an inspection in May 2022, though the inspector was unable to gain access. The property shows a pattern of maintenance issues concentrated in late 2021, with many complaints related to water leaks, windows, and sanitation problems. However, there has been a significant reduction in complaints and violations in recent years, particularly regarding rodent and bedbug issues, suggesting improved management and maintenance practices. The building's most recent rodent inspections in 2023, 2024, and 2025 have all passed, indicating compliance with health and safety requirements.
