Augrented Insights Report for 634 St Nicholas Avenue

The six-story, 60-unit building at 634 St. Nicholas Avenue in Harlem, owned by Dio Del Rosario, has been facing several ongoing maintenance challenges, particularly related to water issues and elevator service.

As of June 2025, there is an open complaint regarding a door issue, while previous complaints this year (February 2025) about building-wide heat/hot water problems were resolved. The building experienced multiple water-related incidents in August 2024, including heavy flow leaks and slow leaks, along with concerns about unsanitary conditions related to pest infestations and garbage storage. Notably, there were violations issued for ceiling paint/plaster issues and various maintenance problems affecting apartments 2H and 4H.

The elevator system has been a recurring concern, with multiple complaints between 2019-2025 about single device service and no alternate service availability, leading to several Environmental Control Board violations. Recent rodent inspections in 2025 revealed regular rat activity, though there have been some successful bait applications. The building has maintained a pest-free status for bedbugs in the most recent three reporting periods (2021-2024), with only two infested units reported in 2019 and one in 2018.
