1148-1150 Filbert St, San Francisco, CA 94109

The two-unit multi-family residential building at 1148-1150 Filbert Street in Russian Hill, owned by Nicholas J. Elliott, was constructed in 1914 and is classified as a Flats & Duplex building with two stories. The property has undergone several significant improvements over the past few decades, with the most substantial being a voluntary lateral strengthening project in 2018 costing $55,000, followed by structural modifications later that year.

Earlier maintenance included a reroofing project in 2006 ($6,480) and concrete passageway repairs in 2000 ($5,000). A notable historical improvement from 1989 involved the addition of new features including an eating area, lighting, bath, benches, and windows. The building has experienced recurring sewer issues, with documented sewage backup incidents in 2017 and 2019 involving a 4-inch vent line.

The property has no records of major safety violations or emergency responses. A complaint about illegal short-term rentals in 2018 was addressed, with a Notice of Violation issued and the listing removed, though there was an outstanding penalty fee. Recent maintenance and service calls primarily involve external matters such as street cleaning and parking enforcement, with multiple reports of illegal parking in the vicinity during 2024. The building's documented history shows regular upkeep and prompt attention to structural and maintenance needs, particularly regarding seismic safety improvements completed in 2018.
