4475-4477 Mission St, San Francisco, CA 94112
The three-story, five-unit multi-family residential building at 4475-4477 Mission Street in the Excelsior neighborhood, owned by Diane L Szucs Trust 2002 and constructed in 1930, has undergone several significant safety and infrastructure improvements over the past two decades. Most notably, in 2021, the building received an important fire safety upgrade with the installation of eight low-frequency sounders in sleeping areas and associated electrical work to bring the fire alarm system into compliance with SF Fire Code requirements.
The building has also undergone routine maintenance and safety improvements, including the installation of an exterior stairwell handrail in 2010 to address a citation, though this work was part of a broader set of repairs required due to multiple housing inspections. The property has experienced a series of housing inspections between 1999 and 2010, with several violations documented and subsequently resolved, including issues related to fire safety systems, stairway conditions, and painting requirements.
A notable incident occurred in 2004 involving a rooftop fan system that was allegedly blowing grease onto an adjacent property, which was resolved within two months. More recent records from 2024 show numerous parking enforcement calls and some minor building maintenance issues, including garbage debris reports and a graffiti complaint, though these do not appear to indicate any significant safety concerns. The building's fire alarm system has experienced periodic malfunctions, with documented service calls in 2020, but no injuries or major incidents have been reported.
