Augrented Insights Report

The Mcalpin Apartments is a historic 8-story multi-family residential building located at 423-439 Stockton Street in Union Square, containing 78 units and constructed in 1911. The building has undergone several significant infrastructure improvements over the past two decades, including an elevator replacement in 2007 ($100,000), multiple fire safety upgrades in 2022-2023, and the installation of a new domestic hot water boiler in July 2024.

Recent maintenance issues have raised concerns about resident safety and comfort, with documented problems including elevator functionality, mold, plumbing leaks, and pest infestations between 2019 and 2023. The building has also experienced recurring fire safety violations, with multiple citations issued between 2022 and 2024 related to alarm systems, sprinkler systems, and general fire code compliance. Recent complaints from 2023-2024 have centered around various maintenance issues, including elevator problems, mold concerns, and a notable incident in 2021 involving sewage water leakage that required emergency response.

The property has maintained active compliance with fire safety regulations through ongoing upgrades, including the installation of low-frequency sounders in sleeping areas as per current fire code requirements. Building management has addressed several infrastructure needs, such as the recent hot water boiler installation and fire alarm system upgrades, though some resident complaints regarding timely responses to maintenance issues persist. The property's historical records show consistent attention to major building systems, including electrical upgrades, roof replacement, and fire safety improvements, while recent fire violations in 2024 related to various safety systems suggest ongoing attention to fire safety compliance requirements.
