246-248 21st Ave, San Francisco, CA 94121

The two-unit residential building at 246-248 21st Avenue in the Central Richmond neighborhood, owned by G & Lika Yu Ng Rev, was constructed in 1922 as a two-story flats and duplex structure. The property has undergone several significant improvements over the years, with the most recent being an electrical service upgrade to 200 amps, issued in January 2025.

Previous renovations include two bathroom remodels (in 2009 and 2015) involving new tiles, sinks, and toilets, as well as a complete reroofing in 2009 and the installation of aluminum windows in 1986. The building has experienced numerous parking-related issues in recent years, particularly between 2019-2022, with multiple reports of vehicles blocking the driveway or parking on the sidewalk, resulting in some citations being issued.

These incidents, while not directly related to the building's condition or safety, indicate ongoing challenges with neighborhood parking enforcement. Additionally, there were two sanitation-related issues noted in 2022, including a general cleaning matter involving loose garbage in June and a report of garbage cans being left out continuously in August 2008, though this latter incident is now quite dated. The building's maintenance record shows regular upkeep and modernization, with particular attention paid to bathroom facilities in multiple renovation projects, suggesting proactive property management.
