129-131 12th Ave, San Francisco, CA 94118

The property at 129-131 12th Avenue is a two-unit, two-story multi-family residential building located in the Lake-The Presidio neighborhood. Built in 1912 and currently owned by the Whilt 1998 Living Trust, this flats and duplex structure has undergone several significant improvements over the years. The most recent major renovation occurred in 2016, involving bathroom upgrades with the installation of a new bathtub and shower valve, as evidenced by both building and plumbing permits totaling approximately $12,228.

Prior to this, in 2008, substantial infrastructure work was completed including a sewerline replacement and some street-related improvements. One of the more significant exterior upgrades took place in 2006 when vinyl siding and insulation were installed on the building's sides, though not on the front, at a cost of $12,000. The property has experienced various maintenance and environmental issues typical of its age and location.

Recent incidents include a parking violation on the sidewalk in June 2024 that could not be located by responding officers. Other notable events include a human or animal waste cleanup in 2019, graffiti removal in 2015, and two separate reports of abandoned vehicles in the vicinity (2012 and 2016), though in each case, the vehicles were gone upon official inspection. A temporary moving sign request was processed in November 2015, and there have been no reported building code violations or safety concerns in the available records. The property's maintenance history suggests regular upkeep of both interior and exterior features, with no recent major structural or systems deficiencies reported.
