840-842 Filbert St, San Francisco, CA 94133

The Wong Family Living Trust owns this century-old multi-family residential building, located at 840-842 Filbert Street in Russian Hill. The 2-unit, 2-story structure was constructed in 1910 and has undergone several significant maintenance and improvement projects over its lifetime, with the most recent major work being a $14,000 re-roofing project completed in 2017.

The building's maintenance history shows regular upkeep, including multiple re-roofing efforts in 1990, interior remodeling of kitchen and bath facilities in 1987, window improvements in 1986, and a basement alteration for a wood frame deck installation in 1985. More recently, the plumbing system received attention in 2015 with the replacement of the house trap and sewer line.

The property has experienced recurring issues with illegal parking, particularly in 2021 and 2022, though these incidents have been promptly addressed through parking enforcement actions. There was a documented street space permit issued in 2011, and while various maintenance and improvement works suggest regular upkeep, there are no recorded violations or safety concerns in the available data. The building's permit history indicates a pattern of proactive maintenance, with significant improvements spaced approximately every decade, suggesting appropriate attention to building preservation and modernization requirements.
