1816-1818 47th Ave, San Francisco, CA 94122

The property at 1816-1818 47th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Outer Sunset neighborhood. Built in 1963 and currently owned by Anthony K & Rose L Chan, this flats/duplex building has undergone limited major maintenance, with records showing only one significant improvement: a completed reroofing project in 1998 (Permit #9800851).

The building experienced a notable maintenance incident in October 2010, when multiple violations were documented in Unit #1818, including issues with a malfunctioning toilet and peeling paint in the rear left bedroom bathroom, which were all abated by November 30, 2010. More recently, the property has generated several 311 calls between 2013 and 2024, primarily concerning external maintenance issues.

These include recurring problems with sewer vent covers (missing/damaged in 2018 and 2019), noise complaints (most recently in October 2024), and other minor issues such as street lighting problems and illegal postings. The property's maintenance history shows occasional responsiveness to issues, as evidenced by the resolution of the 2010 violations and various 311 complaints, though the relatively infrequent major repairs and improvements raise some questions about ongoing maintenance practices. The most recent activity on record includes a noise complaint from October 2024 and a street lighting issue reported in September 2024.
