1250 48th Ave, San Francisco, CA 94122

The 12-unit, 2-story multi-family residential building at 1250 48th Avenue in the Outer Sunset, currently owned by the Tung Kon Cheung Trust, has undergone several significant safety and structural improvements since its construction in 1962. Most notably, the building completed its mandatory soft-story seismic retrofit work as a Tier 4 property in 2018, securing a Certificate of Final Completion (CFC).

Recent fire safety upgrades include a 2023 fire alarm system enhancement with 12 horn/strobe installations to meet San Francisco Fire Code requirements, following multiple documented fire alarm system inspections and violations between 2018 and 2024, demonstrating ongoing attention to life safety systems. The building has had several substantial maintenance and repair projects, including the 2018 replacement of damaged stairs in the lightwell ($25,000) and joist repairs due to dry rot in 2021 ($3,000). Historical issues included a significant cluster of interior violations documented in 2000 related to water damage, mold, and various structural concerns, all of which were abated by June 2000.

The property has addressed various infrastructure upgrades over the years, including a complete unit renovation in 2010 (kitchen and bath remodel) and window replacements in 2005. An illegal unit was removed in 2011, returning the building to its proper configuration. Recent building history shows regular maintenance and compliance with safety requirements, though there have been recurring issues with fire alarm systems requiring attention and verification between 2018 and 2024, with the most recent complaint from August 2024 being marked as "Condition Corrected" in October 2024.
