Augrented Insights Report

The three-story, 10-unit multi-family residential building at 455-457 Ellis Street, managed by S4 Development LLC, has experienced persistent maintenance and safety issues since its construction in 1911. Most recently, the property has faced significant problems with water intrusion and mold, with multiple complaints filed in 2024 (June and August) reporting leaks affecting kitchen, living areas, and ceilings, along with confirmed mold presence.

There have been recurring issues with building systems, including a series of fire safety violations from 2022-2024 related to extinguishers, alarm systems, and exit reliability. The building's structural and safety concerns are documented through recent permits (2023) for window replacements and compliance repairs costing $22,000, addressing previous violations from 2022-2023. Historical records show the building has battled similar maintenance challenges over the years, with notable events including the 2018 cancellation of a $60,000 fire escape replacement project, various plumbing issues (including a 50-foot sewer replacement in 2020), and multiple building violations related to mold, ventilation, and security systems in the early 2000s.

Recent 311 calls between 2023-2024 indicate ongoing issues with exterior cleanliness and waste management in the surrounding area. The building's fire safety history includes several false alarms and sprinkler system incidents, though no civilian injuries have been reported. While some violations have been abated, including recent fire safety issues, the recurring nature of plumbing, mold, and fire safety concerns suggests ongoing maintenance challenges within the building.
