Augrented Insights Report for 51 Catherine Street

51 Catherine Street is a 5-story, 20-unit Old Law Tenement building constructed in 1900 and currently owned by Danny Guo. The property has experienced recurring heating and hot water issues, with multiple emergency complaints recorded between February and April 2024, along with similar complaints in late 2024. Window maintenance has also been a persistent concern, with violations issued for window pane issues noted in both May 2024 and November 2024.

A significant cluster of violations was documented in August 2024, including concerns about self-closing doors, window guards, and fire escape access. While the building has maintained compliance with rodent inspections as evidenced by passing inspections in March 2025, September 2024, and other recent dates, there was one instance of "Rat Activity" recorded in September 2022. The Department of Buildings records show several historical issues, including three ECB violations from August 2018 related to sidewalk shed safety and expired permits.

An active ECB violation from January 2018 remains regarding exhaust discharge placement. The building has consistently reported no bedbug activity in its annual filings from 2019 through 2024, indicating effective pest management. Additionally, recent documentation shows improved window maintenance compliance, with violations from 2024 being promptly addressed, though an open violation remains regarding a glass pane issue in Apartment 15. The property has maintained regular rodent inspections, with all recent inspections passing, suggesting effective management of pest control protocols.
