Preservation Contacts

Among the National Trust for Historic Preservation's most frequent collaborators in protecting America's heritage are statewide and local preservation organizations and state historic preservation offices (SHPO).

  • A statewide organizations are nonprofit groups, normally supported by voluntary memberships, that work across its state to promote good preservation practices. A local organization is a similar organization, except that it focuses on a specific community or metropolitan area.
  • Each state must have a publicly-funded SHPO, a government agency whose responsibilities include identifying historic properties, considering National Register nominations, reviewing federal projects for their impact on historic properties, and providing assistance to federal agencies, state and local governments, and the private sector.
