4036-4038 California St, San Francisco, CA 94118

The two-unit, two-story multi-family residential building at 4036-4038 California Street, located in the Lake - The Presidio neighborhood, is a 1904 flats/duplex structure currently owned by the Mary Ann Goto Living Trust. The building underwent substantial improvements in 2015, with significant work completed including kitchen and bathroom remodels in both units, window replacements, electrical upgrades, and plumbing improvements, all totaling approximately $80,000. Specific upgrades in 2015 included the replacement of 17 vinyl windows, complete remodels of two kitchens and bathrooms, reroofing, foundation repair work, and improvements to the rear staircase.

During this period, the property also saw comprehensive infrastructure updates, including electrical panel upgrades, water heater replacements, heating system upgrades, and plumbing work involving water pipes and sewer lines. The building's maintenance history shows regular attention to infrastructure, with street space maintenance permits issued throughout 2015, including sidewalk repairs. A notable safety and structural improvement was the foundation upgrade and rear staircase replacement completed in 2015.

The property had at least one documented incident in January 2022 involving offensive graffiti on city property, which was subsequently addressed by City Services. A previous sewer line replacement was completed in 2007, indicating ongoing maintenance of critical systems. The extensive 2015 renovation work appears to have brought the building's systems up to modern standards, with no recent permits or permits filed for major repairs or improvements, suggesting the building has been stable since the extensive upgrades.
