514-518 Clayton St, San Francisco, CA 94117

The three-unit residential building at 514-518 Clayton Street in the Haight Ashbury neighborhood, owned by the Mary Martha Smith 2008 Trust, is a three-story flats and duplex structure built in 1908. The building has undergone several significant maintenance and safety improvements over the years, including a perimeter foundation bolting with expandable anchors in 1992 and reroofing work in 1996, though both permits are now expired.

The property has experienced recurring issues with water damage and mold, with a notable complaint in 2012 regarding mold behind a sink affecting tenant health, and a leaking roof complaint in 1996. Two routine housing inspections in 2002 and 2006 revealed multiple safety and maintenance violations, including security deficiencies, fire safety issues, and sanitation concerns, though all of these violations were abated by February 27, 2002. Recent history of the building has been marked by ongoing maintenance challenges and neighborhood concerns, with multiple 311 calls in late 2024 regarding street conditions including human waste, debris, and graffiti.

There have been three recorded fire incidents, including a contained cooking fire, a building fire (though with no civilian injuries), and an unintentional alarm activation, indicating some level of fire safety system operation. The most recent building activity on record is a street space permit issued in July 2017, and there are currently two open 311 cases regarding environmental health and traffic signage as of January 2025. The building's record shows a pattern of maintenance issues being addressed, though many permits have expired and recent repair history is minimal.
