3330 25th St, San Francisco, CA 94110

The two-unit residential building at 3330 25th Street in San Francisco's Inner Mission, owned by Deng Glen Guoxiang, is a two-story flats and duplex structure dating back to 1900. The building's permit history reveals several maintenance and improvement projects over the decades, including dry rot repair and bathroom renovations in 1989, reroofing that same year, a failed garage modification attempt in 1991, and sidewalk repairs in 2002.

Recent issues in the immediate vicinity have primarily involved urban cleanliness challenges, with multiple reports of encampments (most recently in December 2024 and November 2023), and instances of human waste or debris requiring municipal intervention between 2022 and 2024. A construction-related noise and loose plate issue was reported and resolved in October 2023, though the specifics of the construction work were not detailed.

The building's fire incident record shows three alarm-related events, all occurring in 2023, including a false alarm, unintentional alarm activation, and a malfunctioning smoke detector - none of which resulted in civilian injuries. The frequency of encampment-related responses, with at least six documented cases between 2022 and 2024, and multiple reports of sidewalk cleaning needs including human waste removal, suggests ongoing challenges with the immediate street environment. While the building itself has undergone periodic maintenance and improvements, as evidenced by historical permits, the most pressing issues appear to be related to the surrounding public space rather than the structure itself.
