4122-4124 18th St, San Francisco, CA 94114

The property at 4122-4124 18th Street is a mixed-use building located in the Eureka Valley/Dolores Heights neighborhood, consisting of two residential units and ground-floor commercial space. Built in 1910 and currently owned by the Mark C Raggio Trust, this single-story flat and store building has undergone several notable renovations and maintenance projects over the past two decades.

The building has received consistent maintenance attention, including a roof replacement in 2019 ($10,000), an HVAC unit replacement in 2015 ($16,867), and most significantly, comprehensive interior improvements in 2016 ($48,000) that included bathroom installations, electrical upgrades, and flooring work to convert the space from an HIV resources center to a fitness studio. Earlier improvements from 2002 included the replacement of nine windows on multiple building facades.

The building's recent history shows some challenges related to external maintenance, with multiple 311 calls in late 2024 regarding graffiti and waste management issues. Notably, there was a significant safety concern in 2010 when a rotting backyard fence was reported as a hazard, though this complaint was ultimately resolved in 2014. The property has also been the subject of various planning inquiries, including a proposed conversion of the second-story dwelling unit to commercial use and a change of use request in 2016 for the ground floor space to be utilized as a personal service "Pilates studio." While the building's infrastructure and systems have been maintained through regular updates, the recent spate of graffiti and waste management issues suggests ongoing challenges with exterior upkeep, though most of these have been resolved through official channels.
