10 Lupine Ave, San Francisco, CA 94118

10 Lupine Avenue is a three-story, 30-unit multi-family residential building constructed in 1957, currently owned by Castle Enterprises. The building has undergone several significant safety and infrastructure improvements, including a comprehensive fire system upgrade in 2023 ($25,000) featuring new panels, smoke detectors, heat detectors, and low-frequency horns in all units, as well as a mandatory soft-story retrofit completed in 2015 ($16,050). Recent fire safety issues were noted, with a sleeping area violation issued in November 2023, though this has since been abated.

The building's maintenance history shows consistent attention to infrastructure needs, with multiple boiler replacements (most recently in 2011), window upgrades in 2004, and fire alarm system improvements in 2023. The property has experienced several compliance issues in the past, particularly in 2016 when multiple fire safety violations were documented, including problems with fire proofing, smoke enclosure doors, fire extinguisher maintenance, and paint conditions - all of which were abated by March 2017. Earlier issues included unsafe siding concerns in 2009 and asbestos shingle problems in 2009, which were resolved.

Recent external concerns have been documented through 311 calls, primarily related to sidewalk conditions due to tree roots, though these issues were closed as resolved. Regular routine inspections have been conducted throughout the building's history, with the most recent fire safety violations being addressed through proper channels. The building's overall record shows a pattern of responsive maintenance and improvements, with particular attention to fire safety systems and structural requirements.
