Augrented Insights Report for 447 Dekalb Avenue

447 Dekalb Avenue is a 4-story, 7-unit Old Law Tenement building located in Bedford-Stuyvesant and owned by Nikolaos Leonardos. The building, constructed in 1905, has experienced recurring issues with heat and hot water systems, with the most recent outage reported in December 2024 affecting the entire building. A series of plumbing-related emergencies were documented in March 2024, indicating ongoing infrastructure challenges.

The property has also faced maintenance issues related to cooking gas systems, with multiple complaints recorded in 2020-2021 showing patterns of building-wide problems. More recent violations from 2023-2024 include defective self-closing doors in various locations (including the fourth-story bulkhead and vestibule entrance) and a significant fire escape ladder defect noted in May 2023. The building's maintenance history reveals several concerning patterns, including multiple heat and hot water complaints, plumbing issues, and safety violations.

While the property has consistently passed bedbug inspections from 2019-2024, rodent activity remains a persistent problem, with recent inspections in 2022 and 2025 showing rat activity. The 2023 inspections resulted in violations related to window guards in apartments 2L and 3R, and a mold issue was documented in bathroom of apartment 2R. A significant amount of debris was noted in the cellar area during a May 2023 inspection, and multiple violations related to self-closing doors were documented during the same period. The building has had some successful remediation of issues, as evidenced by several violations being closed, but the frequency and nature of complaints suggest ongoing maintenance challenges.
