What matters for project planning
This is the trade where a Certificate of Appropriateness is most likely to apply, and where it can change the answer rather than merely add a step. On a designated property, window review can reach sash configuration, material and profile, and it may carry an expectation that original units are repaired rather than replaced -- which is a different project with a different price. With dozens of registered resources across the city-county government, designation is genuinely common here, and it is settled by address rather than by how a street looks. Confirm status before anything is ordered.

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. Verify each of those with Athens-Clarke County and with whichever provider you select, before the first day of work.
