401-405 Filbert St, San Francisco, CA 94133

The 9-unit, 3-story apartment building at 401-405 Filbert Street in Telegraph Hill, owned by Th Eco Llc, was constructed in 1906 and has undergone numerous renovations and improvements over the past several years. Most recently, in 2023, Unit 403 received a comprehensive $55,000 renovation including bathroom and kitchen updates with new finishes throughout, completed in June 2023.

The building has seen significant modernization efforts including the installation of sprinkler heads on the 4th floor in 2021 ($4,000), and major interior remodeling work in 2020 ($200,000) that encompassed multiple units and common areas. The property has also undergone window replacements in 2016, updating 8 windows to match fiberglass units previously installed in other apartments. The building has experienced some maintenance challenges over the years, particularly in 2012 when complaints were filed regarding stucco cracking and interior wall damage, though these issues were subsequently addressed and abated by June 2012.

Previous fire safety concerns were documented between 2015-2023, including issues with street numbering, sprinklers, and exit maintenance, all of which were marked as "Condition Corrected" upon reinspection. While the building's systems and structures have generally been well-maintained with regular updates to modern standards, recent 311 calls in 2024 have primarily concerned external matters such as graffiti and sidewalk cleaning rather than building-specific issues. The most recent building permits and inspections indicate ongoing investment in maintaining and upgrading the property, with particular attention to unit modernizations and fire safety systems.
