421 Fair Oaks St, San Francisco, CA 94110

The two-story, four-unit multi-family residential building at 421 Fair Oaks St in Noe Valley, owned by Duffy Frank & Monica Trust, has been standing since 1961 and has undergone several significant maintenance and safety improvements over the decades. The building's maintenance history includes a roofing project from 1989, though this permit has since expired, and completion of work to comply with a Department of Public Works report from 1983.

In the mid-1980s, the property underwent important safety enhancements, including the installation of self-closing devices on entry and exterior doors, as well as modifications related to "Code work 3r-1179" in 1984. The building has been subject to routine housing inspections over the years, with documented inspections in 2002, 2009, and most recently in 2017.

While the 2009 inspection was resolved within one day, the status of 2017's inspection remains indeterminate in the records. The only recent complaint on file was a resolved 311 call from January 2021 regarding improperly affixed illegal postings, which was addressed by the Department of Public Works Operations. It's worth noting that there are no recorded building code violations or serious complaints in recent years, suggesting generally attentive property management during this period, though the age of some permits and the lack of more recent permits could indicate minimal recent modifications to the building's infrastructure or systems.
