300-312 Pioche St, San Francisco, CA 94134

The property at 300-312 Pioche Street in the Portola neighborhood is classified as a multi-family residential building containing two separate structures on one parcel. The complex has faced significant permit and code compliance issues over the years, most notably regarding unauthorized dwelling units and safety violations. In 2022, a major violation was documented (complaint #202296209), revealing unauthorized conversions to multiple dwelling units with illegal kitchen installations, leading to the current permit application (202303274482) to convert an unauthorized dwelling unit to ADU status, with the project currently filed and estimated at $45,427.

Earlier, between 2010-2011, the property underwent several attempts to address violations, including work to remove unauthorized kitchens and legalize existing bathrooms (BPA #201104134001), though multiple operational permits were involved, including electrical and plumbing permits to complete necessary modifications. The property has also experienced various safety concerns, including insufficient natural light and ventilation, unauthorized windows, and unauthorized electrical and plumbing installations, which were documented in 2010-2011 violations. More recent history shows ongoing maintenance and safety concerns, particularly regarding tree maintenance and garbage issues, as indicated by multiple 311 calls from late 2024 to early 2025, including reports of fallen trees and debris.

A fire safety complaint about blocked exits was filed in October 2023, though it was determined to be without merit by December 2023. The property has a history of building envelope maintenance work, including roof replacement in 1988 and repairs to dry rot in 1992. In 2017, there was a tenant buyout at a different address (160 Harvard Street) involving four tenants and a payment of $75,000. The current status of the property includes several open maintenance issues as of 2025, particularly related to tree damage and debris management on and around the property.
