461-463 Frederick St, San Francisco, CA 94117

The two-unit residential building at 461-463 Frederick Street, owned by Ellen Conant, is a 2-story flats and duplex structure built in 1909. The property has undergone several significant renovations, most notably between 2005-2012, including a substantial $300,000 remodel of the two-story and basement area, complete rewiring with 200-amp service installation, and the addition of 60 lights, 30 switches, and multiple outlets. In 2012, interior improvements were made including the installation of new recessed lights and kitchen modifications.

The building faced serious safety concerns in December 2005 during excavation work for a horizontal addition, resulting in multiple building violations for inadequate shoring and safety precautions, though these were ultimately abated by January 2012. Recent history shows ongoing maintenance and safety management, with the most recent fire incident recorded as a carbon monoxide situation with no civilian injuries. Between 2023-2024, there has been a pattern of parking enforcement issues near the property, with multiple reports of blocked driveways being reported and addressed by parking enforcement.

There have also been several incidents of graffiti reported in 2023, though these were marked as resolved. The most recent building-related issue was recorded in December 2024 regarding garbage and debris, specifically involving human waste or urine, which was resolved without any required work. The property appears to be actively maintained with regular updates to electrical systems, though there have been some recurring issues with exterior maintenance and nearby parking compliance.
