433-435 Filbert St, San Francisco, CA 94133

The two-unit residential building at 433-435 Filbert Street, located in Telegraph Hill and owned by Laura A & James L Stankard, is a two-story flats and duplex structure built in 1924. The property has undergone various modifications and faced several maintenance issues over the years.

In 2018, there was an ambitious proposed project (permit #201802131095) with an estimated cost of $900,000 that aimed to significantly expand the building with a new basement, fourth floor, elevator installation, and rear yard extension, though this permit was ultimately cancelled. The building experienced a tenant buyout in October 2016, with one tenant receiving $70,000. The property's maintenance history shows several infrastructure improvements, including a comprehensive electrical system upgrade in 2007 that included new lighting, switches, receptacles, and a 200-amp electrical service installation.

There have been various reported issues with the surrounding infrastructure, including a collapsed sidewalk reported in 2015 (though this condition was not found upon inspection), a pavement defect in 2020, and a burnt-out streetlight that was replaced in 2012. The building's planning records indicate a granted reasonable modification variance in January 2018, allowing for modifications to accommodate ADA accessibility, though the major expansion project was not completed. The property has maintained its two-dwelling configuration throughout these changes, with all planning and building permits ultimately closed or completed, though some permits, such as the 2018 expansion proposal, were cancelled before work commenced.
