The definition of subdivision was expanded to Definitions. At this time the Michigan rural population was 2,084062. The average size of farm was 150 acres. Since the enactment of the 1967 Subdivision Control Act, property could be split into any number of parcels over 10 acres without platting, but only 4 parcels 10 acres or less in every 10 years. As a result, Michigan now has many parcels 10.1 or even 10.01 acres in size.
Exempt splits are actually exempt.
Divisions must go through a simplified approval process. Subdivisions , as in the past, must be platted. If the splitting and sale of a parcel does not create any parcel less than 40 acres, the split is exempt from regulation so long as it is accessible. Zoning ordinances, building codes, and other applicable laws may still regulate the use of the property. To be exempt, the split cannot create any parcel less than 40 acres.
