“Four properties outside the Frederick Town Historic District may be deemed historically significant, marking the first time the city could place a historic preservation overlay on a site without first being prompted by a building demolition plan.
…
Until now, the city’s practice has been to consider overlays for buildings outside the historic district based on two criteria: The building must be at least 50 years old, and the owner must apply to demolish the building, an exterior wall or roof without plans to replace it. City officials have discussed expanding or redefining the basis of historic designation review on many occasions in recent years, but have ultimately decided against major changes.”
