1251-1253 46th Ave, San Francisco, CA 94122

The two-unit residential building at 1251-1253 46th Avenue in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1907, currently owned by Sebastian Properties LLC. The property has undergone several significant structural improvements over the years, with the most substantial work occurring in 2005 when major renovations included foundation replacement, lower slab work, steel beam installation, and new deck construction at both units, along with stairwell relocation and first-floor overhang infill.

More recent improvements include electrical system upgrades with two 200-amp service installations in April 2023, and earlier work in 2018 attempted to remodel a first-floor 2-bedroom unit's kitchen and finishes, though this permit was withdrawn. The building's maintenance history shows attention to essential systems, including a sewer/housetrap upgrade in 2016, reroofing work in 2009, and various electrical improvements between 2005-2006.

The property has experienced typical urban residential issues as documented in 311 calls, with the most recent incidents involving garbage and debris and illegal parking in late 2023. Several street maintenance issues have been reported and resolved over the years, including pavement defects in 2018 and 2020, as well as a manhole cover issue in 2015 that was addressed through official notice. The building appears to have maintained its structural integrity through proper maintenance and upgrades, with no recorded safety violations or significant resident complaints beyond general urban maintenance issues.
