639 9th Ave, San Francisco, CA 94118

The two-story, four-unit multi-family residential building at 639 9th Avenue in San Francisco's Inner Richmond neighborhood is a 1923 apartment structure currently owned by Gene W Y Yee and Flora H Trs.

The building's documented history shows minimal inspection activity, with only two routine apartment housing inspections recorded in the past 23 years. The first inspection occurred in August 2000 and was completed by mid-September 2000, while the second took place in February 2008 and was resolved on the same day it was filed.

Both inspections were conducted by Housing Inspection Services and have since been marked as not active. The sparse record of complaints or violations, with only these routine inspections to note, suggests limited reported issues within the building during this period, though it is worth noting that routine inspections are standard procedure rather than indication of problems.
