3914-3916 26th St, San Francisco, CA 94131

The two-unit residential building at 3914-3916 26th Street in Noe Valley, owned by Genaro E Castillo, is a two-story flats and duplex structure built in 1924. The property has undergone several significant improvements over the past few decades, with the most substantial recent work being a window replacement project in 2005 that converted 15 aluminum windows to wood, completed at a cost of $13,996.

Other notable renovations include electrical upgrades in 2004 that moved fuses from a closet to circuit breakers in the basement, and historical compliance work in 1992 that involved fire-proofing the basement and garage. The building has experienced some maintenance issues in its history, as evidenced by multiple instances of graffiti in 2011 (both offensive and non-offensive), and a roof-related permit from 1993 that expired without completion. While there were several permits pulled in the 1980s for various repairs and compliance issues, most of this work appears to have been completed or properly resolved.

The property has had minimal recent issues, with only routine municipal service requests noted in the past decade, including a scooter queue service request in 2019 and an abandoned vehicle report in 2014. No major safety violations or building code issues are currently on record, and the most recent building improvements suggest regular maintenance of the property's systems and features. The building's permit history shows a pattern of addressing necessary improvements, though some older permits from the 1980s and 1990s are marked as completed or expired.
