Augrented Insights Report

111 Trenton Street is a 3-story, 4-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, currently owned by Victoria T & William J Ng R. Originally built in 1956, this apartment building has undergone significant transformations, most notably converting a ground-floor commercial space and garage into residential units between 2006-2016, increasing the unit count to 5.

Recent improvements include a closet addition in 2019 (Unit #3), comprehensive unit renovations in 2018-2019 (including kitchen and bathroom upgrades), and an electrical system upgrade to 100A service. The building has experienced recurring maintenance and safety issues, with several violations between 2005-2017 related to fire safety, sanitation, and temperature control systems, though these have all been resolved.

A routine inspection in 2023 identified issues with smoke alarms, fire extinguishers, and fire escape ladders, which were subsequently addressed and abated in April 2023. The property has maintained regular responses to 311 calls and city inspections, with recent activity primarily involving exterior maintenance and compliance matters. The most recent building improvements suggest a focus on modernizing individual units while maintaining compliance with current safety standards, with no active building violations or complaints as of now.
