469 25th Ave, San Francisco, CA 94121

The property at 469 25th Avenue in San Francisco's Richmond District is a two-story, two-unit multi-family residential building constructed in 1900, currently owned by Calvin Wai Chu. The building has undergone several significant structural and safety improvements over the years, beginning with foundation repairs in 1987 (permit #8710540), followed by the installation of a fire sprinkler system in 1989 (permit #8904203). There were earlier changes to the property, including demolition of a previous two-family dwelling and plans for a larger four-unit structure in late 1987, though only the existing two-unit configuration remains.

In 1986, repairs were made to address issues with rear stairs and dry rot. The building's systems have seen upgrades as well, including a furnace replacement in 2012, though this permit has since expired. The property's maintenance history includes a 1999 routine housing inspection that was completed, and it has experienced minimal major incidents.

A notable event was a confined cooking fire in 2014 that caused no civilian injuries. Recent infrastructure issues included a sewage backup in January 2017, which was promptly resolved. The building's more recent history shows typical urban maintenance issues, such as sidewalk cleaning and parking enforcement matters, with the most recent incident being a parking violation in October 2024. The property appears to be well-maintained, with regular updates to safety systems and infrastructure, though some permits have expired without record of final resolution in the available data, such as the 1987 foundation repair permit and the 2012 furnace replacement permit.
