General Residential Neighborhood (RN-4)
The RN-4 General Residential Neighborhood Zoning District is intended to accommodate mixed medium density residential development within the City of Knoxville. Single-family, two-family, and townhouse dwellings are permitted with low-rise multi-family dwellings and new development forms such as pocket neighborhoods allowed by review and in some cases with special use approval. The RN-4 District is intended to be applied to neighborhoods that are characterized by such mixed residential development, or that have been identified as areas where such development would be suitable in the future. Limited nonresidential uses that are compatible with the character of the district may also be permitted.
