3909-3911 Mission St, San Francisco, CA 94112

The two-unit multi-family residential building at 3909-3911 Mission Street in Bernal Heights, owned by Angie Xiaofang Li, has experienced several notable events since its construction in 1978. The property underwent significant improvements in 2013, including an electrical survey and final inspections of completed work, which were properly documented and resolved. Two fire-related incidents were recorded in 2018 involving blocked exits and alarm systems, though both issues were promptly corrected within about six weeks.

The building's history also includes a 2007 violation for trash accumulation that endangered property, which is listed as closed. The most recent and concerning pattern of incidents involves multiple 311 calls between September 2024 and January 2025, with particular attention to parking issues, including six reports of abandoned vehicles and two complaints about blocked driveways. The property has also experienced recurring problems with street cleanliness, as evidenced by three reports of garbage and debris, and one report of a burnt-out streetlight was resolved.

Notably, there is currently an open noise complaint from October 2024. Historical records from 1989 show some modifications to the building's office space and installation of air conditioning units. The duplex structure, classified as flats & duplex, has maintained its two-story configuration throughout its documented history.
