1645 Filbert St, San Francisco, CA 94123

The three-story, 18-unit multi-family residential building at 1645 Filbert Street in Cow Hollow, constructed in 1926 and currently owned by Paul H Offenbacher Trustee, has undergone several significant maintenance and safety upgrades over recent years. The building completed its soft story retrofit requirements as a Tier 2 building, receiving its Certificate of Final Completion (CFC), demonstrating seismic improvement compliance. Between 2016-2018, the property underwent various plumbing updates, including the replacement of multiple water heating systems and the installation of 19 earthquake gas valves in 2012, indicating proactive infrastructure maintenance.

The building has experienced recurring boiler permit compliance issues, with violations noted in 2000, 2006, and 2017 related to boiler operation permits. However, these violations were eventually resolved, with the most recent boiler-related work occurring in 2018 involving the removal of outdated water storage tanks. Fire safety inspections between 2009-2023 have shown mostly compliant conditions, with the most recent 2023 sprinkler system complaint found to have "No Merit." Regular routine housing inspections, including a 2013 safety inspection and various plumbing updates in 2016-2018, suggest ongoing oversight of building maintenance standards.

Recent occupancy experience has mostly involved external issues, with multiple reports of abandoned vehicles near the property during 2021-2022, though these were ultimately determined to have "No Merit." The building's maintenance history shows attention to infrastructure improvements, particularly concerning water systems and seismic safety. While there have been several regulatory compliance issues related to the boiler system over the years, these have been addressed through subsequent permits and repairs, including a structural details upgrade in 2017 that cost $5,000. The property has demonstrated a pattern of addressing routine violations and has maintained regular building systems upgrades, with the most recent significant work involving water system equipment replacement in 2018.
