400 Baker St, San Francisco, CA 94117

The 10-unit, three-story apartment building at 400 Baker Street in Park North, owned by Thomas Joseph Linehan, was constructed in 1986 following permits issued in 1985, including a foundation design revision. The building has undergone regular routine housing inspections dating from 1998 through 2023, with several significant issues noted over the years.

Most recently, in 2023, there is an active routine inspection on record. Notable past concerns include a 2021 complaint about insect/rodent infestation in Unit 202 that was reported to have persisted for over a month, and a series of fire safety violations between 2017-2024 related to alarm systems and fire extinguishers, though all were marked as "Condition Corrected" or "Abated" after appropriate remedial actions were taken. The building's fire safety history reveals multiple instances requiring attention to fire alarm systems and extinguishers, with violations specifically issued in June 2017 for both issues, though these were subsequently abated.

In terms of maintenance and safety infrastructure, there were two violations in 2007 regarding smoke enclosure doors and gas utility shutoff tools, both of which were resolved by May 2007. The property has experienced four fire-related incidents since 2009, including non-fire smoke detector activations and a confined cooking fire, but notably none resulted in civilian injuries. Recent activity near the building has primarily involved external issues like graffiti and street cleaning concerns, as documented in multiple 311 calls between November and December 2024, though these appear to be related to public space maintenance rather than building operations.
