1100 Clay St, San Francisco, CA 94108

The three-story, six-unit multi-family residential building at 1100 Clay Street in the Nob Hill neighborhood, owned by Ke Holdings, LLC, has undergone several significant improvements since its construction in 1900. Most notably, the building completed mandatory soft-story seismic retrofit work in 2017 (at a cost of $60,000) as a Tier 3 building, demonstrating compliance with San Francisco's earthquake safety requirements. Recent improvements include a complete laundry room remodel in 2022 (costing $6,000), which included new equipment as well as electrical and plumbing upgrades.

The building has a history of diligent maintenance, with prior work including roof replacement in 2016 ($10,000), exterior siding repairs, and various unit remodels. Several building violations were recorded in 2000 related to fire safety and electrical systems, though these were promptly addressed and abated by August 2000, and there was a routine inspection in 2016 that noted various items requiring attention, including water heater issues and fire safety requirements, which were subsequently resolved. The property has experienced a few maintenance challenges over the years, including issues with broken windows in 2019-2020, though these were eventually addressed.

Recent 311 calls from 2023-2024 have primarily concerned external matters such as sidewalk cleaning and graffiti removal, which are typical for urban properties. The building's permit history indicates regular upkeep and modernization efforts, with the most recent significant work being the laundry room renovation in 2022. The addition of an ADU at the basement level was filed in 2018, though the status of this project is not clearly indicated in the recent records. The property has generally maintained compliance with housing codes, with past violations being addressed promptly through proper channels.
