421-423 Scott St, San Francisco, CA 94117

The two-unit residential building at 421-423 Scott Street in Hayes Valley is a two-story flats and duplex structure built in 1922, currently owned by Fannie Mae Mcdaniel 2016 Re. The property has undergone several significant maintenance and improvement projects over the years, with substantial work completed in 2004 including window replacements, roof framing work, and a major electrical upgrade that involved installing new panels, circuits, and fixtures. More recent maintenance includes a water heater replacement in 2021 and the repair of stairs in 2012.

The building has experienced some infrastructure challenges, evidenced by an attempted sewer lateral replacement in 2010, though this permit ultimately expired. The property has been subject to various municipal service calls, primarily related to external issues rather than building-specific problems. These include multiple parking enforcement calls for blocked driveways and sidewalk parking between 2018-2025, several instances of graffiti (most recently in 2024), and occasional street cleaning needs.

There was one building-related complaint in 2004 regarding dust and debris affecting surrounding properties, though this was promptly resolved within two days. While the property has had its share of typical urban maintenance issues, there are no recent or recurring concerns that suggest significant resident experience or safety impacts. The building's permit history demonstrates regular maintenance and upgrading of essential systems over time, with no current outstanding building maintenance issues on record.
