1447 20th St, San Francisco, CA 94107

The 3-unit multi-family residential building at 1447 20th Street in Potrero Hill, constructed in 1950 and currently owned by Ddk Missouri Street Llc, has undergone several significant improvements over its lifetime. Most notably, in late 2012, substantial renovations were completed including comprehensive remodeling of Units 507 and 509, featuring updates to three bathrooms and two kitchens, with new fixtures, cabinets, and appliances totaling approximately $45,000. During the same period, important structural work was performed to the ground floor garage and basement/crawl space, including foundation strengthening and the installation of shear structural plywood, costing $6,500.

In 2013, the building received an electrical upgrade with the installation of a ground wire linking both PG&E services. The property has maintained regular upkeep, as evidenced by the installation of two awnings in 2003 and various maintenance work including window replacement in 1996 and reroofing in 1994, though some permits from the 1990s are now expired. Recent activity around the property has primarily involved external maintenance issues rather than building systems concerns.

Between July and December 2024, there have been multiple reports regarding the building's surroundings, including several incidents of graffiti on the sidewalk, issues with garbage and debris, and parking enforcement matters. The most pressing recent concern appears to be exterior maintenance, with three open graffiti cases reported in 2024 and one noise complaint. These external issues were generally handled promptly by city services, though one graffiti case from November 2024 remains unresolved as of the report date. The building's documented history shows a pattern of regular maintenance and upgrading, with no recorded tenant buyouts at this address in the available data.
