859 14th St, San Francisco, CA 94114

The two-unit residential building at 859 14th Street in San Francisco's Duboce Triangle neighborhood is a 2-story flats and duplex structure built in 1902, currently owned by the Guy F Thomas Revocable Trust. The most significant recent improvement to the property was completed in 2019, when a $56,400 reroofing project was undertaken to replace the top roofing system with a solar-ready asphalt shingles installation.

This work was properly permitted and completed, demonstrating attention to property maintenance. The building has experienced several maintenance and quality-of-life issues in recent years, with the most recent being an open case of graffiti on the building (as of August 2024) and multiple instances of sidewalk obstruction and street cleaning issues. Between 2022 and 2024, there have been recurring problems with blocked sidewalks and display merchandise, as well as issues with garbage, debris, and improperly stored toters.

A sidewalk defect was reported in November 2020, but following an inspection in December 2020, no actionable conditions were found. The property has a clean safety record with no recorded fire incidents or civilian injuries, though there was one instance of a malfunctioning alarm system. The building's permit and inspection history suggests regular attention to structural maintenance, while the 311 call records indicate ongoing environmental and accessibility challenges in the immediate vicinity.
