All districts
The five-member Board of Zoning Appeals hears administrative appeals, special exceptions, and variances. A variance application follows denial of a permit, and the Board must find a particular physical hardship (not mere inconvenience), conditions not general to the district, no self-created hardship, and no special privilege; financial return alone is never a basis. A variance cannot authorize activities in a district that the ordinance does not permit, so use changes need rezoning or a special exception instead. Overlays, planned-development approvals, recorded conditions, and Article VI exceptions can change the parcel-specific result; confirm with Smyrna Planning and Zoning before relying on this answer.
