Tiny House Zoning in Tennessee

Anderson County, home to Oak Ridge and Clinton in East Tennessee, combines Manhattan Project history, TVA lake recreation, and mixed development patterns creating varied tiny house opportunities across incorporated cities and unincorporated county areas. The county distinguishes between incorporated municipalities (Oak Ridge, Clinton, Norris, Oliver Springs—each with own codes and some with building inspection programs) and unincorporated areas where county zoning applies. In county-administered areas, regulations focus primarily on septic system approval, and tiny houses on permanent foundations may proceed where they meet Tennessee Department of Environment and Conservation septic requirements and county Land Use policies. Minimum square footage regulations exist for some zones but enforcement varies. THOWs face classification as recreational vehicles with occupancy restrictions, though enforcement depends on location and visibility. Water availability varies—Oak Ridge and Clinton have municipal water and sewer, while unincorporated areas require wells (generally feasible through East Tennessee geology) and septic systems. Norris and Melton Hill lakes create recreational appeal but also TVA shoreline management regulations affecting waterfront properties. The county's terrain includes valleys, ridges, and Oak Ridge's restricted federal areas. Before purchasing land in Anderson County, determine whether your property falls under city or county jurisdiction, review applicable zoning and building codes, verify water and sewer availability or confirm well and septic feasibility, check for TVA easements if near lakefront, and understand that Oak Ridge maintains more stringent development standards than surrounding areas due to its planned community heritage and ongoing federal presence.

Bedford County, centered on Shelbyville in Middle Tennessee's rolling hills and horse farming region, offers relatively affordable land and straightforward rural zoning but requires attention to water and septic infrastructure. The county distinguishes between incorporated Shelbyville, Normandy, Wartrace, and Bell Buckle (each with own codes) and unincorporated areas where county zoning regulations apply. In unincorporated county areas, tiny houses on permanent foundations may qualify as residential structures if they meet Tennessee septic requirements and county zoning standards, though minimum square footage requirements may exist for primary dwellings in some zones. The county's focus is typically on septic approval rather than strict size regulations. THOWs are classified as recreational vehicles and face occupancy restrictions, though enforcement in rural areas varies. Water availability is critical—incorporated towns have municipal systems, but rural properties require wells (generally feasible in Middle Tennessee karst terrain, though depth and yield vary) with state Water Resources Division approval and septic systems approved by the Tennessee Department of Environment and Conservation based on soil percolation tests. Bedford's rolling terrain (elevation 700-1,100 feet) brings moderate climate and productive agricultural soils. The Tennessee Walking Horse National Celebration in Shelbyville creates tourism but also right-to-farm considerations. Before purchasing land in Bedford County, verify water availability through well feasibility assessment, confirm septic approval prospects with soil evaluation, check whether the property falls under city or county zoning, review any subdivision covenants from horse farm developments, and understand that the county's agricultural character means infrastructure self-sufficiency is expected in rural areas.

Benton County, along the Tennessee River and Kentucky Lake in West Tennessee, combines TVA lake recreation, rural character, and minimal regulatory oversight that can accommodate tiny houses with proper infrastructure. The county administers basic zoning in unincorporated areas, while Camden runs its own municipal code.
