Is a permit required for an Agricultural barn?

T.C.A. 43-1-113 states: "Agriculture" means the land, buildings and machinery used in the commercial production of farm products and nursery stock. 

Under the law, an agricultural use or activity must involve the commercial production of farm products or nursery stock.   Property owners wishing to have a building or structure considered for exemption from regulation for an agricultural purpose may do so by providing evidence satisfactory to the Building Codes Department that the agricultural use or activity qualifies as an agricultural purpose. To qualify for this exemption and so that the Building Codes Department may verify the ‘commercial production of farm products and nursery stock’, the property owner shall fill out an Affidavit and provide evidence required by the Building Codes Department that satisfactorily demonstrates that the agricultural use or activity qualifies as an agricultural purpose. Such evidence may be one or more of the following: an IRS Schedule ‘F’ from their most recent years tax return, an Agricultural Sales and Use Tax Exemption certificate issued by the Tennessee Department of Revenue, any other information, including any other tax records or financial information, and/or site inspection to confirm that the property qualifies as a working farm as prescribed by law.
