5726 California St, San Francisco, CA 94121

The two-unit residential building at 5726 California Street, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1947, currently owned by the Bruce & Belle B. Y.

Lam Revocable Trust. The property's recorded history shows relatively minimal permitted work over the past decade and beyond.

In February 2011, a street space and sidewalk-related permit was issued with a nominal cost of $1, though the nature and scope of this work appear to be minimal. Most significantly, as of December 2024, there is an active plumbing permit (PW20241209647) allowing for the replacement of the sewer line and house trap, representing an important infrastructure upgrade to the property's waste management system. This recent work suggests the owners are addressing critical systems maintenance, though it also indicates that the building's plumbing infrastructure may require attention after nearly eight decades of service.
