Full Breakdown
Sumner County Building & Codes requires a zoning permit for any storage building over 200 square feet, including portable buildings delivered on skids and pole barns used for storage. The fee is a flat $100 for structures from 200 to 600 square feet; above 600 square feet it is based on construction cost using the ICC valuation table, Group U. The county does not inspect a structure issued only a zoning permit, but a one-time site visit is made before construction to confirm setback compliance, so the site plan must show distances to property lines. Metal shipping containers are barred in residential and agricultural districts. A shed cannot be used as living quarters.
