331 25th Ave, San Francisco, CA 94121

The property at 331 25th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1915 and classified as a Flats & Duplex building, it is currently owned by Raymond M Quan Bypass Trst.

Over the past two decades, the building has undergone several permitted improvements, including a kitchen renovation in 2010 ($2,500) and electrical upgrades in 2006 involving the installation of three meters, one light, and four receptacles. A street space permit was also issued in 2004. The building's maintenance and incident record reveals some ongoing concerns, particularly with tree-related issues, which have been a recurring theme from 2016 through 2021.

These include problems with overgrown trees blocking sidewalks, property damage from trees, and various maintenance needs that were primarily resolved through the city's StreetTreeSF program. More recently, in 2021-2022, there have been two documented water-related incidents near the property involving a fire hydrant and street flooding, though these were not directly related to the building's infrastructure. The property's unit count and historical permit activity suggest reasonable maintenance and improvement efforts by ownership, with particular focus on electrical infrastructure and interior upgrades.
