How to read it. The regional map sorts hundreds of local district names into nine broad classes; tap a spot to see the district's local name. A hatched area is land whose class differs between the 2015 and 2025 regional maps. Many are real rezonings, but some come from the region redrawing or relabeling a district, so check the city or township record before reporting one as a rezoning. Areas of 2 acres or less and slivers along boundaries are left out. This map is not a legal zoning determination; the local zoning office has the official map.
