461-463 10th Ave, San Francisco, CA 94118

The property at 461-463 10th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1900 and currently owned by Randall P. Choy and Jiali Zeng, this structure has undergone several significant modifications and faced notable compliance issues over its history.

In 2002, the building faced enforcement action for unauthorized construction, specifically regarding a rear vertical/horizontal addition and dry rot in front stairs, which created unstable conditions. These violations were addressed through a $100,000 permitted project completed in 2002-2003, which enclosed a first-floor rear area measuring 12'9" x 25'0" to create a family room, along with associated electrical work including new service installations and fixtures. The property has had various maintenance and infrastructure issues documented through 311 calls, including a sewage backup incident in 2016, several pavement defect reports in 2015, and street cleaning matters in 2019.

While there were attempts (now withdrawn) to convert the residential units into a child daycare facility, these proposals were not pursued to completion. The most recent building complaints are from 2021 regarding parking issues, though these were external to the property itself. The building's electrical system was notably upgraded in 2003 with the installation of a comprehensive electrical service including 200A service with two meters, lighting, switches, and receptacles, indicating a significant modernization of the building's infrastructure during that period.
