456 Hill St, San Francisco, CA 94114

The two-unit residential building at 456 Hill Street, owned by Achtenberg Benjamin Alexand, is a 1900 flats/duplex structure located in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant improvements and faced various compliance issues over the years. Most recently, in 2024, there was a sewage backup incident from the side sewer vent and multiple tree-related issues including hanging limbs and a damaged tree.

The building has a history of street space permits, with seven such permits issued between 2005 and 2017, suggesting regular use of public space for construction or maintenance purposes. The property has experienced two notable building violations: one in 2006 regarding damaged sidewalk/driveway conditions that required maintaining a clear 3-foot wide accessible walkway, and another in 2012 concerning expired permits for retaining wall work. Both violations were eventually abated, with the sidewalk issue being resolved in 2012.

A sprinkler system issue was reported and corrected in September 2021. The building underwent a reroofing project in 2013, and in 2005, significant work was done including an underground electrical conversion and retaining wall construction with soil engineer revisions. Multiple 311 calls in 2024 indicate various neighborhood issues including abandoned vehicles, pavement defects, and parking violations near the property, though these are not directly related to the building's condition or safety.
