1350-1360 Mason St, San Francisco, CA 94133

The 7-unit multi-family residential building at 1350-1360 Mason Street in Nob Hill is a 2-story structure built in 1925, currently owned by the Yin Bing Wong Revocable Trust. The property has undergone several significant renovations and faced various challenges over the years. Most notably, it experienced a fire incident in 2016 affecting the basement areas, which required approximately $16,000 in repairs to walls and ceiling joists, along with associated plumbing and electrical work.

The building has seen recent maintenance activity with a $28,000 reroofing project completed in 2022. Between 2008-2013, the ground floor underwent multiple commercial improvements, including the installation of a fire suppression system, expansion of restaurant space, and various plumbing and electrical upgrades totaling over $150,000. The building's history includes several regulatory inspections and violations, with a significant set of citations issued in 2004-2005 regarding exterior paint, sanitation, fire escape maintenance, and lead hazard concerns, all of which were subsequently abated.

More recent routine inspections have not revealed any outstanding violations. The property has generated multiple 311 calls in 2024, primarily related to parking enforcement issues, and experienced several fire department responses for medical assists and elevator rescues, though none resulted in civilian injuries. Recent planning records indicate proper approvals for the ground floor restaurant space, which operates under ABC Type 41 and Health Department permits. The building's systems have received regular maintenance and upgrades, including the installation of new electrical service with multiple meters in 2008, though minor issues like the flue installation complaint from 2008 and construction work without permit in 2013 have been documented and resolved.
