2421-2427 Clement St, San Francisco, CA 94121

The three-story mixed-use building at 2421-2427 Clement Street in San Francisco's Central Richmond neighborhood, owned by Jeffrey C N & Shirley Tsai, was constructed in 1900 and contains three residential units plus commercial space. The property has undergone several notable changes and improvements over the past few decades, with the most significant recent development being the transformation of a former retail space into an ice cream shop (Let's Roll) in 2021, which included comprehensive renovations to meet ADA requirements and modern building standards.

This commercial conversion in 2021 involved substantial work including new plumbing fixtures (mop and prep sinks, 3-compartment sink, hand sinks), HVAC system updates, electrical improvements (subpanel, outlets, lighting), and facade modifications to reduce window size. Prior to this, the commercial space underwent interior fixtures removal work in 2019, and the building received a roof replacement in 2005 (though that permit expired). The building's maintenance and safety record shows generally proper upkeep, with only one fire complaint recorded in 2009 regarding blocked exits that was determined to have no merit, and a smoke detector activation incident with no fire or injuries.

Recent years have seen multiple 311 calls related to street cleaning and debris removal around the property, with the most recent instance in June 2024, though these are typical urban maintenance issues rather than building-specific concerns. The property has maintained compliance with necessary permits and regulations, as evidenced by the multiple completed permits for various improvements, and has navigated the required planning processes for changes in use and modifications to the building's commercial space. The building's infrastructure has seen regular updates, including the installation of a new furnace for the whole unit in 2021 and various plumbing and electrical upgrades to support modern commercial use.
