455-459 Linden St, San Francisco, CA 94102

The two-unit residential building at 455-459 Linden Street in Hayes Valley, built in 1913, has experienced several significant maintenance and safety issues over the past decades. The most pressing current concerns involve active violations from November 2019 related to general dilapidation, including problems with ceilings, walls, windows, and an urgent plumbing safety issue regarding water heater installation that requires proper metal strapping. These violations seem to stem from earlier problems, including a burst water heater in the basement that caused mold growth and interior damage.

The building has a history of infrastructure maintenance, with roof replacements in 1986, 1992, and 2005, and various plumbing updates, including a 2019 project to bring water heaters up to code. A notable historical incident occurred in 2006 when an adjacent construction project caused foundation concerns, though this violation was eventually abated. More recent records show the property has faced multiple challenges typical of urban environments, including multiple 311 calls in 2024 regarding encampments, waste management, and tree maintenance issues in the immediate vicinity.

There was also a 2019 complaint about possible illegal units or rooms, though this was quickly resolved. While the building has undergone various repairs and improvements over the years, including electrical work to repair the meter socket in 2011 and gas line installations in 2008, the persistence of active housing code violations as of 2019 indicates ongoing maintenance challenges. The building's ownership history shows Mark C Price as the current owner, and the property has maintained its classification as a Flats & Duplex building throughout its history.
