519-521 Filbert St, San Francisco, CA 94133

The two-unit multi-family residential building at 519-521 Filbert St in Telegraph Hill, owned by the Ann Ding Yuen Jeong Trust, is a two-story flats and duplex structure built in 1907. The building's most significant recent maintenance work was completed in December 2021 when a $11,000 reroofing project was undertaken and successfully completed.

The property has experienced various challenges in 2023-2024, with multiple 311 calls reporting issues. These include three separate instances of garbage and debris (specifically human waste or urine) in October 2024, two general cleaning cases in late 2023, and incidents of graffiti on the building in August 2023.

The building has also faced some neighborhood disturbances, with two open noise complaints reported in October 2024 regarding amplified sound electronics and other noise. Additional issues have included improper street pole postings in October 2024, which required the intervention of the SES Graffiti Crew to address multiple affixed items on various street poles and fixtures. The building itself hasn't required major structural modifications since the 2021 roofing work, though it has had to contend with various environmental and maintenance challenges typical of its urban location.
