TN Code § 13-3-411 (2021)
2021 Tennessee Code|Title 13 - Public Planning and Housing|Chapter 3 - Regional Planning|Part 4 - Regional Planning Regulations|§ 13-3-411. Prerequisites for Issuing Building Permits or Erecting Buildings — Proposed Permanent Easements

  From and after the time when the platting jurisdiction of any regional planning commission has attached as provided in § 13-3-402, no building permit shall be issued and no building shall be erected on any lot within the region, unless one (1) of the following four (4) criteria is met:  The street giving access to the lot upon which the building is proposed to be placed has been accepted or opened as, or shall have otherwise, received the legal status of, a public street prior to that time;    The street corresponds in its location and lines with a street shown on a subdivision plat approved by the planning commission and recorded in the register of deeds; and   Whenever the street or other infrastructure improvements as denoted on the plat have not been completed, there shall be an adequate, valid, and enforceable bond, or an adequate, valid, and enforceable other guarantee for the completion of the improvements, which shall be held by the appropriate officials as provided in § 13-3-403. This subdivision (a)(2)(B) shall not be construed to require duplicate bonds or to require additional bonds when an adequate bond to complete the infrastructure is already in effect. This subdivision (a)(2)(B) shall not be construed as requiring a building contractor to post the bond required by § 13-3-403 on the infrastructure for the subdivision if such building contractor is not a developer of the subdivision;      The lot fronts upon a permanent easement which conforms to all rules, regulations and specifications applicable to the permanent easement of the planning commission or other department, division or agency of the county; provided, that such rules, regulations, and specifications governing permanent easements shall not take effect until such rules, regulations, and specifications are approved by the county legislative body in a resolution by a two-thirds (2/3) vote; and   The permanent easement has access to an existing highway, street or thoroughfare, or with a street located or accepted by the county legislative body after submission to the planning commission, and in case of the planning commission's disapproval, by the favorable vote of the county legislative body required in § 13-3-406; or     The street corresponds in its location and lines with a street shown on a street plat made and adopted by the commission.     The planning commission or other department, division or agency of a county as approved by the planning commission may recommend to the county legislative body regulations to govern a proposed permanent easement in a proposed subdivision, as defined in § 13-3-401. The purpose of the regulations is to ensure that the county is not responsible for the future maintenance of such permanent easement.   Any building erected or to be erected in violation of this section is an unlawful structure, and the state building commission or the county attorney or other official designated by the county legislative body may institute a civil action to enjoin such erection or cause it to be vacated or removed.
