417 Frederick St, San Francisco, CA 94117

The 417 Frederick Street property is a two-unit multi-family residential building located in the Parnassus/Ashbury Heights neighborhood. Built in 1900, this two-story flats and duplex structure, currently owned by Donald S.

Mitchell, underwent significant renovations between 2017-2018 including comprehensive updates to both units' kitchens and bathrooms, major plumbing system upgrades (covering two kitchens, four bathrooms, two laundry rooms, and gas lines), installation of two new gas furnaces, and complete electrical system modernization with 200-amp service and updated wiring. The renovation project, valued at $60,000, was carefully documented through multiple permits, including E201704214494 and E201704214495 for electrical work, and plumbing permits PP20170606966 and PM20170606967, all of which have been completed. The building's maintenance history shows attention to both interior and exterior upkeep, with earlier permits from 1990 addressing interior plaster and exterior stucco repairs, and terrazzo steps repair.

More recent building concerns have primarily involved external matters, with several 311 calls between 2020-2024 relating to street cleaning issues, including hazardous materials and waste removal. The most recent documented incident was a glass hazard reported in December 2023, which remains open. The property has experienced minimal safety concerns, with only one documented water or steam leak incident reported to the fire department, with no civilian injuries recorded.
