1066-1070 Filbert St, San Francisco, CA 94133

The three-unit residential building at 1066-1070 Filbert Street in San Francisco's Russian Hill neighborhood was constructed in 1909 and has undergone several significant modifications over the years. Most recently, in 2019, substantial improvements were made to legalize an ADU unit and upgrade an apartment unit's bathroom, kitchen appliances, and convert an office area to a master bathroom, with permits totaling approximately $150,000.

The building has experienced various maintenance and safety-related events, including a noteworthy series of fire safety violations in late 2005 that were promptly addressed by January 2006, involving issues with egress obstructions, sprinkler heads, fire extinguishers, and other safety requirements. Recent records from 2023-2024 show several service requests and complaints regarding waste management, including multiple instances of toters being left out continuously, and one sewage backup issue reported in July 2024.

A significant planning process is currently underway, proposing substantial modifications including additional bedrooms, decks, and interior remodeling across multiple units, though these changes are under review and require various permits. The building's history includes some structural modifications, such as a rear yard stairway replacement in 1996, reroofing work in 2005, and recent tenant buyout activity in 2022. The property has also experienced periodic routine housing inspections in 1999, 2002, and 2005, with all issues from these inspections having been resolved.
