Augrented Insights Report

89 Belle Avenue is a 3-unit, 2-story multi-family residential building constructed in 1947 in the Ingleside Heights neighborhood, currently owned by Irwin Ku. The property has experienced significant maintenance and occupancy challenges over the past decade, with multiple periods of vacancy and code violations. Most notably, between 2015-2019, the building faced several violations including fire hazards, structural issues, improper occupancy, and sanitation problems, resulting in multiple Notices of Violation.

In 2018, the building underwent repairs for fire damage, and since 2020, several renovation projects have been attempted, including bathroom remodels and window replacements in different units, though many of these permits have expired without final inspection. Two recent active complaints from 2024 concern unauthorized stucco repairs and multiple expired permits, while earlier complaints in 2023-2024 indicated issues with vacant building security and unauthorized construction work. The building has a history of fire-related incidents, primarily consisting of smoke detector activations and false alarms, though no civilian injuries were reported.

Previous fire code violations from 2016 included concerns with exits, storage, and electrical systems, all of which were subsequently abated. Recent permits show attempts to bring the building into compliance with earlier NOVs through various improvements, including electrical upgrades to 400 amp service and plumbing work, though some permits remain in "Expired" status. A current project under review aims to remodel Unit A, add new windows, and address multiple violation corrections. The property has undergone various maintenance efforts over the years, including window replacements, bathroom renovations, and attempts to address historical issues related to vacancy and security, though many of these efforts have encountered permit compliance challenges.
