1401 25th Ave, San Francisco, CA 94122

The two-unit residential building at 1401 25th Avenue in the Central Sunset neighborhood is a two-story flats/duplex structure built in 1948, currently owned by Reginald David Wong. The building's documented history shows several significant improvements made over the years to enhance safety and functionality.

In 2004, fire sprinklers were professionally installed, and in 2003, window security measures were implemented, including the installation of window guards and a security gate. The ground floor underwent substantial modifications in the early 2000s, transitioning from a computer room to a bedroom, along with the addition of laundry facilities and a full bath in 2001. More recently, there was an attempted installation of solar panels in 2015, though this permit was ultimately cancelled.

The property has experienced some ongoing maintenance challenges, particularly in late 2024 and early 2025, with multiple reports (at least 12 cases) of garbage and debris issues near the property, though most of these were resolved with no further action required. A notable housing complaint was filed in November 2021 regarding uncleaned garbage cans potentially attracting rodents, though this case is currently listed as not active. The building's permit history suggests a pattern of improvements focused on safety and modernization, with most recent activity indicating both regular maintenance issues and environmental sustainability efforts, despite the cancelled solar panel installation.
