Augrented Insights Report

The three-story, 99-unit multi-family residential building at 478-480 Warren Drive in Forest Knolls, built in 1975, has undergone significant modifications and faced numerous maintenance challenges in recent years. Most notably, from 2018 to 2023, the property completed the conversion of its garage space into additional living units, adding a total of 13 ADUs (Accessory Dwelling Units), with associated electrical, plumbing, and fire safety system upgrades. The building has experienced recurring fire safety issues, with multiple violations and complaints regarding alarm systems, sprinkler maintenance, and exit obstructions between 2014 and 2024, with the most recent violations issued in 2023-2024 regarding sleeping area requirements and blocked exits. Recent tenant complaints from 2021 to 2023 indicate persistent building maintenance issues, including water leaks, electrical problems, and window-related moisture and mold concerns.

The property has undergone several fire alarm system upgrades, with permits issued in 2021-2023 for modifications to comply with fire safety regulations. The building's recent history shows attention to fire safety compliance, with multiple permits issued for fire alarm system modifications and maintenance. However, there have been several recurring maintenance issues affecting resident comfort and safety. Notable tenant complaints include reports of water leaks causing ceiling damage, electrical problems, and window-related moisture issues leading to mold concerns. During the 2020 period, there were multiple complaints regarding construction noise, and there have been several fire safety violations related to alarm systems and exit maintenance between 2014 and 2024.

The property has also seen some structural and systems upgrades, including the installation of additional fire sprinklers and the replacement of rooftop storage tanks in 2022. The most recent tenant-related issues primarily revolve around fire safety compliance and building maintenance concerns, though many previous violations have been marked as abated or corrected. The building's management has responded to various violations and complaints, with records showing correction of many fire safety issues through subsequent permits and inspections. Some violations, such as the 2020 fire alarm system violation and the 2024 exit maintenance violation, were marked as "condition corrected." However, the pattern of recurring maintenance issues and the need for multiple fire safety system upgrades suggest ongoing challenges with building systems and resident comfort. While recent permits indicate continued investment in building maintenance and safety improvements, the property has experienced periods of significant construction work and associated tenant disruption.
