449-455 Filbert St, San Francisco, CA 94133

The three-story, 6-unit multi-family residential building at 449-455 Filbert Street in Telegraph Hill, owned by Kenneth J & Barbara L Krzyw, has undergone several significant improvements and faced some notable challenges over its nearly 120-year history. Most recently, as of 2024, the building has received substantial fire safety upgrades including new fire alarm devices, manual pull stations, smoke detectors, and 520Hz low frequency audible signals throughout the units, with the work completed at a cost of $18,000. The building successfully completed mandatory soft-story seismic retrofitting in 2019 (Tier 4), demonstrating compliance with San Francisco's seismic safety requirements.

A significant maintenance issue was reported in September 2019 regarding recurring bathroom flooding with waste in Unit 1, which was noted as a persistent problem over that year. The building's earlier history includes routine inspections, some violations in 2006 related to rooftop deck repairs and wood post maintenance, and historical improvements such as a window replacement project in 1994 and electrical system upgrades in 2010. The recent months of 2024 have seen multiple reports to city services regarding street cleaning and debris, though these issues appear to be more related to the surrounding area rather than the building itself.

The property has undergone various infrastructure improvements over the years, including a significant electrical upgrade in early 2010 involving the installation of residential meters and a 200-amp system. A short-term rental complaint from 2020 regarding unauthorized rentals and associated disturbances was investigated and closed when the responsible party vacated the unit. The building's most recent major work, completed in mid-2024, focused on building-wide safety system enhancements including the installation of low frequency sounders to meet current safety code requirements.
