3319-3321 Anza St, San Francisco, CA 94121

The 3-story multi-family residential building at 3319-3321 Anza Street in San Francisco's Central Richmond neighborhood, owned by Liu Hong & Zhuang Ruiqun, was constructed in 1905 and currently contains 2 units. The building underwent significant safety improvements between 2008-2010, including the installation of a comprehensive fire sprinkler system ($10,000), followed by the installation of a sprinkler monitor system ($1,500) with various safety devices including heat detectors and horn strobes.

In 2010, additional ground floor improvements were made including construction of a bedroom, tool room, storage spaces, and associated plumbing and electrical work ($18,000), though there were concerns raised about these modifications being done without proper permits. The property has experienced recurring sewer issues, with multiple reports of sewage backups between 2021-2024, including a recent incident in June 2024.

There was also a suspension of work in 2007 due to permit violations, and a complaint in 2013 alleging the building had been illegally converted to a multi-unit property with additional mailboxes and back entrances, although this complaint is currently listed as not active. The building's maintenance history shows substantial investment in both safety systems and structural improvements, though the recent pattern of sewer-related incidents suggests ongoing infrastructure challenges. The property has also experienced periodic issues with parking violations, as documented through multiple 311 calls between 2021-2024 regarding blocked driveways and abandoned vehicles.
