470-472 Sanchez St, San Francisco, CA 94114

The 3-unit, 4-story multi-family residential building at 470-472 Sanchez St, owned by Tommy T H & Elizabeth L Lee, was constructed in 1912 and underwent significant safety upgrades in 2009. The most substantial improvements included the installation of a comprehensive fire sprinkler system with 86 new heads ($22,500), a fire monitoring system with alarms and detectors ($4,000), and new plumbing work for two units including waste/vent and water systems.

The building received new electrical systems including 90-amp panels, and all units were upgraded with various modern amenities such as gas fireplaces, kitchen appliances, and electrical features. Prior to these upgrades, the building had several safety concerns noted in a 2004 routine inspection, including lead paint issues, stair repairs, door security problems, and fire proofing needs, all of which were abated by February 2005. Recent maintenance includes a 2020 sewer and house trap replacement.

The property has experienced some external issues as documented in 311 calls, including recent sidewalk defects (March 2022, open), and several parking-related complaints. Two minor incidents were recorded by the fire department: a flammable liquid spill and a malfunctioning alarm system, neither resulting in injuries. While the building's recent history shows no major safety violations or complaints, it's important to note that the last major upgrades occurred over a decade ago (2009), and some systems may now be approaching the end of their typical service life.
