500 Capp Street, the David Ireland House, is an 1886 Italianate home in the Mission District where conceptual artist David Ireland lived from 1975 and transformed the building itself into his greatest artwork, with amber-varnished walls and site-specific installations. Collector Carlie Wilmans founded the 500 Capp Street Foundation in 2008 to preserve it, and it opened publicly in January 2016 as the city's first historic artist's home, offering tours, exhibitions, and artist residencies, still active in 2026.
