1531 Filbert St, San Francisco, CA 94123

The 4-unit, 2-story multi-family residential building at 1531 Filbert Street in Cow Hollow, owned by Family Bypass Trust, was constructed in 1960 and has undergone several significant maintenance and safety updates over the years. Most recently, in November 2024, the building received a substantial reroofing project costing $22,900. Major exterior improvements include a 2015 siding replacement using Hardie Plank lap siding, and in 2011, the installation of approximately 40 feet of tiebacks beneath the building to support nearby construction.

The building has also undergone important infrastructure updates, including water heater replacement in 2017 and house trap replacement at the sidewalk in 2014. The property has faced several safety and compliance issues, particularly during routine inspections in 2002 and 2016. The 2016 inspection revealed violations related to fire safety equipment and carbon monoxide alarms, all of which were abated by June 2016.

Historical records show various building improvements, including vinyl siding installation in 1990 and code compliance work in 1986. More recent fire safety incidents include a carbon monoxide detector activation (with no actual CO detected) and a small intentional outside rubbish fire, neither resulting in civilian injuries. The building's recent maintenance history appears more focused on structural and roofing work, with the most significant recent compliance issue being a fire alarm system matter in early 2022 that was resolved by March 2022.
