422-424 17th Ave, San Francisco, CA 94118

The Chan Family Trust owns this three-story, two-unit multi-family residential building located at 422-424 17th Avenue in San Francisco's Central Richmond neighborhood. Built in 1976, this flats and duplex-style building has undergone several significant renovations and maintenance work over the years. Most notably, in 2017, a substantial exterior remodel was completed at a cost of $36,000, which included installing James Hardie fiber cement siding on the front and right side, replacing 12 fiberglass windows in both upper and lower units, and applying vinyl siding to the rear sides.

The building previously received a one-story rear addition in 2001 valued at $35,000, and historical records show earlier maintenance work including reroofing in 1993 and plumbing updates in 1984. The property has experienced several concerning incidents near its vicinity in recent years, including reports of medical waste and human or animal waste on sidewalks in 2020 and 2018, respectively. In 2014, there was an incident of offensive graffiti on the residential building, which has since been resolved.

A medical waste incident involving needles was reported and resolved in 2020. The building's documented history also includes various administrative matters such as a cancelled 1983 application to revert the building to legal two-unit status, multiple street space permits in 2017, and a 2008 fire complaint regarding blocked exits that was found to have no merit. Recent maintenance issues have included a tree support removal completed in 2021 and several sign-related matters in 2016. Planning records confirm the building's two-unit status with condominium conversion approvals, and recent improvements include the installation of fiberglass windows and siding replacement.
