554 21st Ave, San Francisco, CA 94121

The property at 554 21st Avenue in San Francisco's Central Richmond district is a two-unit, two-story multi-family residential building constructed in 1988, following the demolition of a previous two-family dwelling on the site in 1987. The building's maintenance history shows one major permitted repair: a reroofing project undertaken in September 2000 at a cost of $7,520, for which the permit has since expired.

The structure appears to have maintained its original duplex configuration and ownership, currently held by Emily L Yu, Lilian L Yu, and Yu. The building's service history includes three recorded incidents in the vicinity, though none directly pertain to the building's structural condition or safety.

Most recently, in December 2024, there was an incident involving abandoned furniture that required intervention from Recology, which was subsequently resolved. A bicycle sharing operations complaint was logged in March 2021 and noted by SFMTA, while a utility excavation issue was reported to the Department of Public Works in March 2010. Each of these service calls was appropriately closed following investigation or resolution, but they appear to be routine municipal service matters rather than building-specific concerns.
