342-344 12th Ave, San Francisco, CA 94118

The two-unit residential building at 342-344 12th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1924, currently owned by the Helen Jue Survivor Trust. The property's maintenance history shows regular upkeep, with the most recent significant improvement being a completed re-roofing project in November 2023 costing $15,700.

The building underwent a substantial window replacement in April 2003, with 26 windows being updated from wood to vinyl while maintaining original dimensions, and visible from the street. An earlier re-roofing was attempted in January 1991, but that permit expired.

The property has had minimal street-related interventions, with two identical street space permits issued in July 2011 at a nominal cost of $1 each. There were also two documented 311 calls regarding general street cleaning in 2010 and 2012, both related to loose garbage issues, though these appear to be neighborhood-wide concerns rather than building-specific problems.
