419-421 2nd Ave, San Francisco, CA 94118

The three-story multi-family residential building at 419-421 2nd Avenue in the Inner Richmond, owned by Yuk Ling Ng Revoc Tr, is a 2-unit flats and duplex structure built in 1907. The property experienced a significant adverse event in October 2015 when a fire caused substantial damage to the top unit (421), hallway, light well, and portions of vinyl siding, leading to emergency responses and subsequent building violations. The building underwent extensive rehabilitation in 2016, completed at a cost of $150,000, which included replacing damaged wood framing, updating plumbing and electrical systems, remodeling kitchens and bathrooms, and replacing windows throughout both units.

This renovation also featured the installation of new gas furnaces, service panels, and comprehensive plumbing updates for multiple bathrooms and kitchens. In terms of recent maintenance and resident experience, the building has had several plumbing and electrical upgrades since the 2016 renovations, including furnace and service panel installations. The property has had multiple street-related complaints in recent years, with the most recent being garbage and debris issues in 2024, though these appear to be external to the building itself.

Historical records show earlier improvements including the installation of vinyl siding in 1996 and aluminum windows in 1989. The building's planning records indicate that the 2016 renovation complied with requirements for usable open space and proper bathroom configurations, and documented that more than 75% of the interior framing was replaced during the renovation period. The property has maintained an active but resolving history of 311 calls regarding street cleaning and parking issues, though these are generally related to exterior conditions rather than building-specific concerns.
