1278 4th Ave, San Francisco, CA 94122

The four-story, three-unit multi-family residential building at 1278 4th Avenue in the Inner Sunset was constructed in 2008 following the demolition of a previous single-family dwelling on the site. The building was equipped with modern safety features during construction, including a fire sprinkler system ($22,500), fire alarm system with smoke detectors ($3,500), and comprehensive electrical installations. Initial construction costs amounted to $573,293.

Since completion, the building has undergone several maintenance updates, including interior improvements, heating system installations, and ventilation system modifications across all units. A significant maintenance issue occurred in 2016 when the building was cited for multiple violations related to fire safety and structural maintenance, including missing carbon monoxide alarms, fire extinguisher maintenance issues, and egress obstructions. These violations were all abated by March 2017.

Prior to the 2016 violations, there were several other notable incidents, including complaints about unauthorized construction in 2008 and 1999, and a concerning report in 2002 about garbage accumulation and security issues during the building's transition period between the old and new structures. The most recent building permit activity was recorded in 2012 for siding repairs on the building's rear facade. While the building has experienced various maintenance and compliance issues throughout its history, records indicate that these problems have generally been addressed, with no active violations or complaints as of the latest data. The property is currently owned by Ho Wai King & Zhu Liang Mei.
