121 Yukon St, San Francisco, CA 94114

121 Yukon Street is a two-story, three-unit multi-family residential building constructed in 1908, currently owned by A & M Asset Holdings LLC, located in the Eureka Valley/Dolores Heights neighborhood. The property has experienced significant recent activity, with demolition and construction permits filed in June 2023 for a new four-story building with three dwelling units and a basement, though these permits remain in "Filed" status as of October 2023.

The building has a notable history of violations and complaints, with a particularly concerning cluster of fire safety issues documented in September 2010, including problems with fire sprinklers, fire escape ladders, and the need for professional inspections of building attachments - all of which were abated by October 2010. More recently, in 2022-2024, there have been multiple complaints regarding security concerns and unauthorized access, with reports of squatters and disturbances, suggesting the building may have experienced periods of vacancy or inadequate maintenance. The property's maintenance history shows some attention to upkeep, including a $15,000 reroofing project permitted in 2008.

Recent building permits and planning records indicate plans for substantial redevelopment, seeking variances for rear yard setbacks and utilizing the Fourplex Density Bonus. The site has generated various 311 reports in 2023-2024 primarily related to external issues such as graffiti, security concerns, and routine maintenance matters in the surrounding area, though these are generally not directly related to the building's condition itself. As of October 2023, the status of the demolition and new construction permits remains unresolved, with the project being described as seeking "Informational" status during planning review.
