Rural Residential Mobile Homes Allowed – RUR-MH
Zoning districts in the USA are defined areas regulated by specific laws, determining land use, building types, and development rules. They guide urban and suburban development in alignment with community plans for safety and growth. Districts allow for diverse development like residential, commercial, industrial, or mixed-use, each with unique regulations.
RURAL RESIDENTIAL DISTRICT (RUR)
This category represents primarily those areas that are transitional between
higher density developments and agricultural or conservation uses. This district
is intended to preserve economically viable agricultural land and large tracts of
residential land in order to maintain a rural atmosphere in appropriate areas of
the County. This category allows for residential use at a maximum density of 1.0 unit per 10
acres. Single family residential may be permitted at a density not to exceed one
unit per five (5) acres when having at least fifty percent (50%) open space,
provided additional standards are met, including a PUD as outlined in Chapter
Four. In addition to residential development, the following is a list of land uses with
notations as to whether they are permitted.
