426-428 31st Ave, San Francisco, CA 94121

The four-story multi-family residential building at 426-428 31st Avenue in San Francisco's Central Richmond neighborhood, owned by Jayeshkumar and Pragna Devdhara, has experienced significant structural and water-related issues during its history. Built in 1905 and classified as a Flats & Duplex, this two-unit building underwent major construction work in the mid-2000s that led to multiple complications. Beginning in 2004, major renovation projects included electrical upgrades with a complete rewiring and 200-amp service installation (completed 2005), while the building underwent substantial structural changes including a reconfiguration of the fire escape to the roof.

During this period, the property faced serious construction-related problems, including multiple building violations related to water accumulation issues in the basement that affected neighboring properties (complaints filed in 2004-2006), concerns about unsafe building conditions, and questions regarding concealed work without proper permits. The construction period from 2004-2006 was particularly troublesome, with the building reportedly being temporarily raised for foundation work, which led to concerns about damaging adjacent properties. A series of building permits and renewals were processed during this time, including electrical work for a garage door opener installation and comprehensive rewiring of the entire building.

Various complaints about the construction work emerged, including concerns about water migration affecting neighboring properties (2004-2006), unauthorized work (2005), and roof height modifications impacting neighbor views (2005-2006), though most of these issues were eventually abated by 2006. The building has since returned to regular use status, with the most recent complaints being parking-related issues in 2022 and 2024, though these are unrelated to building conditions. A review of planning records shows attempts to add a second dwelling unit in the RH-2 district, but these efforts appear to have been withdrawn or closed without implementation.
