Augrented Insights Report

The property at 117-119 Trenton Street, located in Nob Hill, is a two-story, four-unit multi-family residential building constructed in 1910, currently owned by the Lam Family Survivor's Trust. The building has experienced several significant maintenance issues over the past decade, with the most recent major work being the replacement of the house trap in April 2023, and reroofing completed in October 2020 at a cost of $13,000.

The building has a documented history of plumbing and structural challenges, including multiple sewer-related complaints in 2019 and 2017, dry rot repairs to stairs in 2017, and various compliance-related work orders between 2011-2012. A routine inspection in 2005 revealed multiple violations requiring attention, including issues with fire safety equipment, security features, and plumbing systems, all of which were ultimately abated by February 2017. The property's maintenance record shows consistent attention to repairs and safety compliance, with fixes to stairs in 2011-2017, ceiling repairs in 2012, and addressing drainage issues in 2017.

Historical maintenance work includes parapet safety bracing in 1986 and various street space and sidewalk repairs. Recent building activity has shown proper response to maintenance needs, with the most recent plumbing work completed in 2023. The building's location has seen periodic issues with street cleanliness and sidewalk conditions, as evidenced by multiple 311 calls for general cleaning and debris removal between 2016-2024, though these are typical for urban environments and not specific to the building's condition.
