811-813 31st Ave, San Francisco, CA 94121

The property at 811-813 31st Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1926 and currently owned by the Derek Brian Yee Revocable Trust, this flats and duplex-style building has undergone several notable renovations over the past decades. The most significant recent improvement was a comprehensive kitchen remodel in 2016-2017 that included appliance upgrades (stove, dishwasher, microwave), electrical installations (lights, switches, range, garbage disposal, and hood), and plumbing updates (new sink and faucet), with associated costs totaling approximately $25,000.

Earlier modifications included substantial horizontal work in 1995 costing $80,000, fireplace relocations and window revisions in 1996, and foundational improvements (mud sill and treated studs) in 1983. The building has an important historical note regarding housing compliance, with a complaint filed in 1995 about an illegal ground floor unit that remained open until 1997, though no recent violations have been recorded. Recent maintenance matters primarily involve external issues, with multiple 311 calls (2023-2024) related to tree maintenance and parking violations, including several instances of vehicles blocking driveways or parking on sidewalks, resulting in citations.

A damaged tree complaint from December 2023 is currently open. The building's permit history also shows some older work, including roofing (1991) and various maintenance tasks, suggesting regular upkeep over the property's history. The most recent documented works (2016-2017) indicate substantial investment in modernizing the building's amenities while the record shows no recent major structural or safety issues.
