1258 19th Ave, San Francisco, CA 94122

The property at 1258 19th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1925 and currently owned by Chen Yong Guang & Wan Qin, this flats and duplex-style building has undergone several significant improvements in recent years.

In 2018, the property received critical seismic upgrades, including the installation of anchor bolts and OSB sheathing on ground floor walls, along with the replacement of two furnaces and repair of a leaking gas pipe. These improvements, along with a completed reroofing project from 2016, demonstrate the owners' commitment to maintaining the building's structural integrity and systems. The building's history includes several complaints about possible illegal units and unpermitted remodeling, dating from 1996 to 2002, though all these complaints are now listed as not active.

Recent maintenance issues in the area focus more on public infrastructure, with multiple reports of pavement defects near the property in 2023, though these are municipal issues rather than building-specific concerns. A single fire-related incident was recorded involving a carbon monoxide detector activation, which was determined to be due to malfunction with no civilian injuries reported. The property has maintained compliance with building codes in recent years, with no active violations or complaints on record since 2002.
