420 32nd Ave, San Francisco, CA 94121

The three-story multi-family residential building at 420 32nd Avenue in the Central Richmond neighborhood, owned by Nguyen Yen Thi, was constructed in 1988 as a flats and duplex structure containing two units. The property's development history shows a significant period of regulatory activity between 1982 and 1986, with multiple cancelled and completed permits related to unit legalization and parking requirements - including attempts to connect records and legalize a second unit, most notably an effort in November 1984 to legalize a second unit by providing an additional parking space, which was ultimately cancelled.

Prior to the current structure, there was a demolition permit issued in October 1986 for a two-family dwelling, followed by the current building's construction. The building's maintenance record shows some attention to basic upkeep, including a reroofing permit from March 1999, though this is now expired.

More recently, there were two 311 calls in 2009 related to street and sidewalk issues near the property, specifically regarding encampment items and general street cleaning needs, which were both addressed and closed by the Department of Public Works Operations. While these external maintenance issues were resolved, they occurred nearly 15 years ago and are not necessarily indicative of current conditions. The property's permit history suggests a complex and somewhat disjointed process of establishing and confirming its two-unit status in the early 1980s, though this indicates successful resolution by the time of construction in 1988, with no recent permits related to unit modifications or conversions.
