663-665 14th Ave, San Francisco, CA 94118

The two-unit residential building at 663-665 14th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure constructed in 1920, currently owned by Yee Yuet Ngor C. The property's documented history shows relatively minimal internal issues, with only one notable building complaint on record from June 2016 regarding improper paint scraping at the back of the building without appropriate containment measures, though this complaint is listed as "Not Active" without a clear resolution date.

The building's external environment has experienced several routine urban maintenance incidents over the past several years. In 2017, there were reports of sidewalk graffiti and loose garbage, both of which were resolved through intervention by city services, including steam cleaning by the SES Graffiti Crew.

A damaged tree was reported and addressed in July 2018. More recent incidents include two occurrences in 2023: one involving illegal parking that was resolved through parking enforcement, and another related to trash dumping that was addressed by park services. It's worth noting that these external incidents appear to be typical for an urban residential area and do not indicate any significant building-specific concerns.
