136-142 Trenton St, San Francisco, CA 94133

The Wong Revocable Trust owns this 5-unit, 3-story multi-family residential building located at 136-142 Trenton Street in Nob Hill, which was constructed in 1910 and is classified as an Apartment building with 5 to 14 units. The property has undergone several significant safety improvements over the years, including a seismic retrofit completed in 2002 costing $38,000, brick parapet bracing in 1986, and reroofing work done in 1991. The building has undergone multiple routine safety inspections by Housing Inspection Services, with the most recent occurring in 2015, which revealed several violations that were subsequently addressed by August 2015.

These violations included the need for carbon monoxide alarms, fire escape maintenance, and stair repairs. A fire complaint regarding blocked exits was also recorded and corrected in August 2011. More recently, there has been a pattern of street and sidewalk maintenance issues near the property, with multiple 311 calls regarding garbage, debris, and sanitation concerns between October 2024 and January 2025.

These calls, while not directly related to building conditions, indicate ongoing challenges with the immediate exterior environment. Two sidewalk blockage incidents were reported in late 2024, one of which remains open as of the latest report date. The building's documented violations and complaints suggest attention to safety systems and regular maintenance has been addressed over time, though the age of the building and its systems may require ongoing monitoring.
