3917 Mission St, San Francisco, CA 94112

The two-unit residential building at 3917 Mission Street in Bernal Heights, owned by Philip S M & Christine Tam, is a single-story flats and duplex structure built in 1929. The building has undergone several significant maintenance projects over its lifetime, with the most recent being a $13,500 reroofing project completed in 2020. Historical records show earlier roofing work in 2001 and 1996, as well as window replacement and wall repairs in 1991.

A notable incident occurred in 2001 when a complaint was filed regarding unauthorized construction of an apartment at the rear of the building, though this issue was quickly addressed within four days. In recent years, particularly from 2022 through 2025, there have been multiple reports of street cleaning and garbage issues near the property, with four separate cases of garbage and debris reported in late 2024 and early 2025. The building's immediate vicinity has experienced recurring issues with loose garbage, with cleaning requests documented in March, October, and December of 2022-2024.

Additionally, there have been two instances of vehicles blocking driveways in 2023, both of which resulted in citations. A manhole cover issue was reported and resolved in October 2022. While these recent incidents primarily relate to street-level concerns rather than building-specific issues, they may reflect general maintenance challenges in the area surrounding the property.
