The C-O Office Commercial District is established to allow professional offices and other small-scale commercial uses with similar characteristics to operate within residential structures along State highways in areas adjacent to commercial zoning districts. The purpose of the C-O district is to allow alternative land uses while retaining single-family resi dences as permitted uses in the district. The district allows non-residential uses which can be accommodated within a converted residential structure, which can be compatible with single family residences, whether located in the C-O district or in adjacent residential districts, and which do not present excessive demands for parking. The C-O district includes development standards to prevent land use conflicts between uses within the C-O District and between C-O district uses and adjacent residential districts. The regulations of this district shall not be interpreted to prevent construction of new buildings for any of the listed permitted or conditionally permitted uses.
