1409 San Bruno Ave, San Francisco, CA 94110

The two-unit residential building at 1409 San Bruno Avenue, located in San Francisco's Inner Mission neighborhood, is a two-story flats and duplex structure built in 1900 and currently owned by Jason Guan.

The property has experienced a notable pattern of graffiti incidents in recent years, with four documented cases between 2024 and 2025 involving both the building itself and the public sidewalk in front. These graffiti cases, categorized as both private and public, include two recent open cases from January 2025 and two resolved cases from August 2024, along with one street-related incident from April 2024.

Other notable incidents include a noise complaint related to a delivery service business in January 2023, an abandoned vehicle report in March 2023 that was resolved when the vehicle was no longer present, and several street maintenance matters including loose garbage removal in April 2022, a defaced parking sign in May 2021, and an illegal parking complaint in October 2020 where the vehicle could not be located upon officer arrival. While not all incidents directly affect the residential experience, the recurring graffiti issues on and around the property represent the most significant pattern of reports in recent years, with particular attention needed to note that two of the most recent incidents from January 2025 remain unresolved as of October 2023.
