Efforts to establish legacy business programs are often spearheaded by neighborhood businesses, business improvement districts, or community-based organizations, such as historic preservation and main street organizations. To generate the political support needed to create new city-run programs, campaigns typically highlight the many contributions that legacy businesses make to the community. Program guidelines and eligibility vary by jurisdiction. In some cities, legacy businesses are required to apply for funding. In others, they must be nominated by an elected official or small business agency. Businesses are often selected based on their tenure, community contribution, and size.
