3440 Pierce St, San Francisco, CA 94123

The building at 3440 Pierce Street is a two-story, five-unit multi-family residential structure built in 1927, currently owned by Bypass Tr-delmon Fmly Tr 20. The property has undergone several significant safety and infrastructure improvements over the past decade, most notably a weak story seismic retrofit in 2016 that included the installation of steel moment resisting frames and foundations ($25,000), and a mandatory fire alarm upgrade in 2023 to comply with California state fire marshal code.

Recent maintenance includes a gas line repair for the stove in July 2023, and the building's fire safety systems have experienced multiple false alarms, though no actual fires have been recorded. The building's infrastructure has received consistent attention, with major works including reroofing in 2015 ($11,000), water main replacement in 2013, and various plumbing upgrades.

However, it's important to note that the building is currently listed as non-compliant with tier 4 soft story requirements, indicating that while many structural improvements have been made, there are still outstanding seismic retrofit obligations. Recent 311 calls show typical urban maintenance issues, including sidewalk defects (2024), animal waste (2024), and tree-related concerns, though most have been resolved promptly. The property has maintained basic habitability standards with no reported injuries from its recorded fire incidents, which have all involved system malfunctions or false alarms rather than actual fires.
