447 21st Ave, San Francisco, CA 94121

The two-unit, two-story multi-family residential building at 447 21st Avenue in San Francisco's Central Richmond neighborhood, owned by Romanov Leonid & Waiprakhon, has a documented history dating back to its construction in 1922. Of particular note is a significant incident from 2002-2003 involving an illegal garage unit, which prompted multiple violations and complaints, including issues related to inadequate lighting, defective outlets, insufficient windows, and poor ventilation.

This situation was eventually resolved through proper permitting and removal of the unauthorized construction, with related permits (200206199463) showing work to revert the ground floor to garage use being completed in 2002. Subsequent property improvements include the installation of vinyl siding on the back of the house in 2009 ($9,000), and plumbing work in 2010 involving new water service installation and water heater replacement, though this permit has since expired. More recent history shows ongoing attention to property maintenance and neighborhood concerns, with multiple street cleaning requests in 2019-2020, parking enforcement issues including driveway blocking citations in 2023, and routine city maintenance such as graffiti removal.

The most recent building-related activities involve two bicycle-sharing service requests in November 2023. The property's historical records show a period of non-compliance regarding unit construction in 2002-2003, but this appears to have been addressed through proper permitting processes, with no active violations or complaints on record since February 2003. The building's maintenance history includes various improvements and regular responses to neighborhood issues, typical of urban residential properties.
