571 Frederick St, San Francisco, CA 94117

The two-unit residential building at 571 Frederick Street, located in the Parnassus/Ashbury Heights neighborhood, is a two-story flats and duplex structure built in 1926, currently owned by Lance D. Hein and Mike Chang.

The building's maintenance history includes a reroofing project from 1996 (now expired) and a completed electrical upgrade in 2008, which involved installing a 200-amp meter main service without residential space heater modifications. The property has experienced recurring issues with driveway access, as evidenced by three separate parking enforcement calls between 2016 and 2024, with the most recent incidents occurring in September 2024 and May 2023, where citations were issued for blocked driveways.

Additionally, there have been two documented instances of offensive graffiti on street poles near the property (in 2010 and 2018), and one tree maintenance request in October 2023 that was subsequently cancelled. The building underwent general cleaning for loose garbage removal in December 2016, and there was a street cleaning response to garbage issues in October 1998 that appears to be logged under the wrong date. While the property's infrastructure upgrades (roofing and electrical) suggest basic maintenance compliance, the periodic parking enforcement issues indicate ongoing challenges with street access management in the vicinity.
