1431-1443 Willard St, San Francisco, CA 94117

The three-story, seven-unit multi-family residential building at 1431-1443 Willard Street, constructed in 1907 in the Parnassus/Ashbury Heights neighborhood, has undergone several significant improvements and maintenance activities over the past three decades. Most notably, in 2018, the building completed a mandatory soft-story seismic retrofit at a cost of $115,000, achieving compliance with San Francisco's soft-story ordinance (Tier 4) and receiving its Certificate of Final Completion.

The building has experienced multiple plumbing and infrastructure issues, including three separate sewage backup incidents in mid-2014, and underwent a significant plumbing upgrade that year involving drain and sprinkler system improvements. Historical records show earlier maintenance work including roof repairs in 1989 and back stair repairs in 1985. The property has undergone regular housing inspections, with routine inspections recorded in 1999, 2007, 2009, and 2010, though no active violations or concerns were noted from these inspections.

Recent activity around the building has primarily involved street-level maintenance, including general cleaning in 2021 and holiday waste removal in 2023. While the building's maintenance history shows attention to structural and safety improvements, including the recent seismic retrofitting, there have been recurring issues with the building's sewer system, particularly evident in the 2014 incidents. All recent building permits and work orders related to building systems have been properly closed out, indicating appropriate follow-up on maintenance activities.
