1846-1848 9th Ave, San Francisco, CA 94122

The property at 1846-1848 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1947 and currently owned by the Tommy Chee Fong Trust. The building has undergone several significant modifications over its history, including a vertical and horizontal addition in 1991, removal of stucco and wood repair due to dry rot in 1992, and reroofing work the same year. In 2003, there was an electrical upgrade involving a 2/0 feeder and underground conversion, though this permit has since expired.

Of particular note are multiple housing code violation complaints related to an allegedly illegal garage-level addition. Between 1996 and 2012, there were three separate complaints about an unauthorized two-bedroom unit charging $1600 in monthly rent, lacking proper utilities and reportedly being uninhabitable under California civil code. The building's recent history has been marked by ongoing parking enforcement issues, with multiple 311 calls reporting sidewalk parking violations between 2018 and 2024, resulting in several citations being issued.

There was also one noise complaint filed in 2021 regarding excessive noise, which was accepted by the department. The property has experienced various maintenance and compliance issues over the years, particularly regarding unauthorized unit modifications, though many of these historical complaints are no longer actively being pursued. The most recent building-related activity on record is from 2024, primarily focusing on parking enforcement matters.
