Within the area of jurisdiction and powers established by section 23-114, the county board may divide the county into districts of such number, shape, and area as may be best suited to carry out the purposes of this section and regulate, restrict, or prohibit the erection, construction, reconstruction, alteration, or use of nonfarm buildings or structures and the use, conditions of use, or occupancy of land. All such regulations shall be uniform for each class or kind of land or buildings throughout each district, but the regulations in one district may differ from those in other districts. An official map or maps indicating the districts and regulations shall be adopted, and within fifteen days after adoption of such regulations or maps, they shall be published in book or pamphlet form or once in a legal newspaper published in and of general circulation in the county or, if none is published in the county, in a legal newspaper of general circulation in the county. Such regulations shall also be spread in the minutes of the proceedings of the county board and such map or maps filed with the county clerk. The county board may decide whether buildings located on farmsteads used as residences shall be subject to such county's zoning regulations and permit requirements.
For purposes of this section and section 23-114.04, nonfarm buildings are all buildings except those buildings utilized for agricultural purposes on a farmstead of twenty acres or more which produces one thousand dollars or more of farm products each year.
