Summary
Knox County's RP Rural Preservation Zone recognizes Tennessee's Right to Farm Act: agricultural uses that are lawful under state law and comply with state regulations are exempt from Knoxville-Knox County Planning Commission review under Zoning Ordinance Sec. 5.23.01. The zone otherwise limits development to uses compatible with long-term farming, capping lot coverage at 10 percent and requiring 15 acres per dwelling.
5.23.01. General description. The rural preservation zone is provided to help insure the continued production of agricultural commodities by encouraging preservation of productive agricultural lands and the open space, wildlife habitat, and scenic corridor value that productive agricultural lands provide. Uses allowed within the district are intended to be limited to uses which are compatible with the long-term agricultural productivity of lands. The general intent of the district is to encourage farming without undue burden on the landowner. Applications for Rural Preservation zoning shall be reviewed for: A.Preservation of agricultural and forest lands and activities;B.Water supply protection; and/orC.Conservation of natural, scenic or historic resources. Note: Certain agricultural uses are permissible by Tennessee state law under the Right to Farm Act and other regulations. These uses, if permissible and deemed in compliance with state regulations, are exempt from planning commission review.

Full Breakdown
The RP, Rural Preservation Zone exists "to help insure the continued production of agricultural commodities by encouraging preservation of productive agricultural lands," and Sec. " The same section carries the county's clearest right-to-farm language: a note explaining that "certain agricultural uses are permissible by Tennessee state law under the Right to Farm Act and other regulations," and that uses meeting that standard "are exempt from planning commission review" entirely, meaning a qualifying farm operation does not need a use-on-review hearing before the Knoxville-Knox County Planning Commission.
Uses permitted outright in the RP zone under Sec. 02 include agricultural production, one office incidental to the farm, roadside stands for produce grown on site, agritourism, employee housing tied to an active agricultural operation, and animal feed and sales yards. Uses permitted on review include rural retreats, utility facilities, churches, dog kennels and bed-and-breakfast lodging. The zone's own area regulations, separate from the right-to-farm exemption, set a 50-foot setback on all sides, a 250-foot minimum lot frontage, 15 acres of lot area per dwelling, a 10 percent maximum lot coverage, and a 35-foot height limit except for silos and other agricultural production and storage structures, under Secs. 05.
Violations & Fines
There is no separate penalty clause for the right-to-farm exemption itself: it simply removes a qualifying agricultural use from the planning commission's use-on-review process. Any other violation of RP zone standards, such as building outside the 50-foot setback or exceeding 10 percent lot coverage, is enforced the same way as elsewhere in the zoning ordinance: the Department of Code Administration and Enforcement can assess a civil penalty of $10 to $500 per day under Sec. 6.20.02.A, with appeal to the Board of Zoning Appeals within 30 days under Sec. 6.60.05.
