Tenn. Code Ann. § 6-54-106: Regulation of powder magazines

The governing body of any incorporated municipality may authorize the building of powder magazines at any safe and prudent distance from the limits of the corporation. When it gives such authority, it shall be by order upon its records, designating and appointing the places within its county where such magazines may be erected, in which it shall be lawful to deposit and keep gunpowder. The corporate authorities shall adopt such regulations in regard to the construction of such magazines as may, in their opinion, best secure the community from danger.
