446-450 14th St, San Francisco, CA 94103

The three-unit residential building at 446-450 14th Street, constructed in 1907, has experienced several notable events throughout its history, with the most significant being an ongoing effort to legalize an apparently unauthorized fourth unit on the ground floor. This unit, reportedly containing a kitchen and full bathroom, was the subject of a 2019 complaint and has led to a filed permit in late 2019 for electrical and fire sprinkler improvements.

The building underwent significant window improvements in 2017, replacing 12 aluminum windows with wood double-hung sashes. The property has seen various maintenance issues, particularly in the late 1990s, including plumbing leaks, electrical problems, and structural concerns, though these were addressed through housing inspections.

More recent concerns have centered around building maintenance and neighborhood impacts, with a notable period of short-term rental activity in 2018-2019 that generated regulatory scrutiny and was subsequently ceased. The building's recent history, particularly in 2024, has involved issues typically associated with urban environments, such as graffiti remediation, noise complaints, and parking enforcement matters. A significant tenant buyout occurred in July 2018 for the 448 address, involving two tenants and totaling $85,000.
