505-509 23rd Ave, San Francisco, CA 94121

The three-unit multi-family residential building at 505-509 23rd Avenue in the Central Richmond neighborhood, owned by Frances Chiu, is a three-story flats and duplex structure built in 1913. The property has undergone several significant renovations and maintenance projects over the past two decades, with the most recent improvements occurring in early 2024, including a comprehensive kitchen renovation valued at $30,000 featuring new cabinets, countertops, sink, light fixtures, and electrical work. In 2018, substantial exterior improvements were completed, including the installation of vinyl siding on the back walls ($36,000) and replacement of 10 street-facing windows with historical-appropriate Marvin wood windows ($11,000).

The building did experience a notable violation incident in 2010 regarding unpermitted construction of front stairs, landings, and alley door work, which was resolved by May 2012 through the proper permits and corrections. More recently, there have been two significant complaints filed in 2024 and 2010 regarding unpermitted construction work, though the 2024 complaint appears to be closed without active status. The 2024 complaint cited unauthorized electrical work and kitchen/bathroom remodeling, while the 2010 complaint concerned front stairway construction and bathroom remodeling work.

The building's plumbing and electrical systems have received attention in recent months, with permitted work on kitchen plumbing and electrical systems in March 2024. Historical records indicate previous routine housing inspections (2000) and various maintenance works including a reroofing project in 2000, stair repairs, and siding work. The property has experienced recurring issues with illegal parking in the surrounding area, with numerous citations issued between 2019 and 2024, though these are external to the building's condition or management.
