1454-1456 10th Ave, San Francisco, CA 94122

The two-unit multi-family residential building at 1454-1456 10th Avenue in San Francisco's Inner Sunset neighborhood has a documented history of maintenance and compliance issues, with the most significant recent concern being an active building complaint filed in September 2024 regarding unauthorized construction in the backyard. This complaint, which remains unresolved as of now, alleges construction of a structure against two fence lines, exceeding permitted height and occupying half of the yard.

The 1926 duplex has undergone several major infrastructure upgrades, including an electrical service upgrade to 200 amps in 2004, plumbing work in 2018 to replace a housetrap, and attempted replacement of two central heating gas furnaces in 2017 (though this permit was marked as expired). The building has received various exterior repairs, most recently in July 2022 when $18,000 worth of work was completed on wood siding, roofing materials, and exterior lighting. The property has experienced several maintenance-related issues documented through 311 calls, including a collapsed sidewalk reported in March 2024 and multiple parking enforcement requests for vehicles blocking driveways between 2018 and 2024.

While the majority of these external incidents have been resolved, they indicate recurring challenges with parking enforcement in the area. Historical records show earlier roofing work was completed in 1988 and 1992, suggesting regular maintenance of this critical building component. The property owner, Juliet Boxer, currently appears to be facing the most pressing concern with the active building complaint regarding unauthorized construction, which could potentially affect the property's code compliance status.
