Dayton, OH Historic Preservation: Historic-Cultural Monuments (2026)

Dayton R.C.G.O. § 150.345.2 creates three historic overlay tiers: HD-1 protects individual or grouped historic properties and governs major modifications only; HD-2 covers districts of largely rehabilitated historic properties and governs both major and minor modifications; HD-3 applies to single properties the Landmark Commission finds so significant that only demolition/removal is regulated. All three tiers together are called the "Dayton Register of Historic Places." The seven-member Landmark Commission that designates and reviews these districts, one registered architect, three residents or business owners within a historic district, one Dayton History or Preservation Dayton, Inc. representative, is established under general code §§ 44.50-44.51.
