The HPOZ was accomplished after years of door-to-door conversations about preservation, the circulation of a pro-HPOZ petition signed by the majority of residents, many outreach meetings involving panel discussions, frequent discussions of preservation in the neighborhood newsletter, dozens of mailings to residents, as well as a 2007 Home and Garden tour fund-raiser sponsored by affiliate neighborhood West Adams. In August, 2008, Wilshire Park Association hosted, at the National Register of Historic Places Art Deco landmark Wiltern Theater, a public meeting for all residents regarding the neighborhood's proposed designation as a Historic District known as a Los Angeles Historic Preservation Overlay Zone. City officials of the Los Angeles Office of Historic Resources held a forum as part of the event attended by over 120 residents at the landmark Ebell of Los Angeles. On November 13, 2008 Wilshire Park was officially designated as an Historic Preservation Overlay Zone.
