439 21st Ave, San Francisco, CA 94121

The 4-unit, 2-story multi-family residential building at 439 21st Avenue in the Central Richmond neighborhood was constructed in 1972 and is currently owned by Yu Lan Fong Yeun Yu. The building's maintenance history shows completed repairs to the siding on both the north and south sides in 2006, a reroofing project in 1993, and brick replacement work at the front of the building in 1989.

The property has undergone two routine housing inspections by Housing Inspection Services in 2002 and 2011, both of which were promptly resolved. The most recent issues concerning the property primarily involve street-level concerns rather than structural or safety matters within the building itself. In December 2024, there were multiple reports of garbage and debris, including furniture, on the sidewalk area, along with one complaint about a blocked driveway that was closed as invalid due to incomplete reporting information.

A building inspection request was submitted and transferred for processing in February 2024, which represents the most recent internal building-related inquiry on record. Other external issues noted in the 311 calls include two parking violations on the sidewalk in 2019, graffiti in January 2019, and a report of human or animal waste in November 2022, all of which have been resolved. The property's maintenance record shows regular attention to structural issues when they arise, with no major safety violations or complaints on file.
