1228-1230 Leavenworth St, San Francisco, CA 94109

The property at 1228-1230 Leavenworth Street is a two-unit multi-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1909, this two-story flats/duplex structure underwent significant renovations and additions between 2015-2016, including a major vertical addition of one story, installation of a new elevator, complete reconfiguration of both units, and extensive updates to electrical, plumbing, and safety systems including a new sprinkler system.

The lower unit was reconfigured into three levels with 4 bedrooms and 5.5 bathrooms, while the upper unit was transformed into two levels with 3 bedrooms and 2.5 bathrooms. Prior to these major works, the building received updates to both bathrooms in 2018, including retiling, fixture replacement, and plumbing work, along with street space and sidewalk repairs. Recent records from 2023-2024 indicate some ongoing maintenance issues, including a sewage backup incident in November 2023 and multiple reports of garbage and debris on the property in late 2023 through early 2024.

There have been several 311 complaints regarding noise (specifically dog barking) and parking issues, though these are generally typical urban neighborhood concerns. The building has gone through various infrastructure improvements over the years, including electrical rewiring, garage updates, and kitchen/bathroom renovations, with the most recent significant improvements focused on maintaining modern plumbing and electrical systems. A smoke detector malfunction was recorded as the only fire-related incident, with no civilian injuries reported.
