What matters for project planning
This is the trade the Board of Historic and Architectural Review reaches most directly. Columbus designates ten historic districts with published design guidelines, and in them windows are among the exterior elements most closely examined -- review can extend to sash configuration, material and profile rather than merely to thermal performance, and in some cases to whether original sash should be repaired instead of replaced. That is settled by address, not by how a street looks, and with ten districts in play it is worth confirming before anything is ordered. The 2038 plan does not reach an opening in a wall.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Run each of those down with the City of Columbus and with the provider you eventually choose before any work starts.
