Zoning Symbols and Names

Zoning symbols vary among communities. An R2 zone in one community is not necessarily the same as an R2 in another community. Frequently, communities use letters of the alphabet as code abbreviations to identify the use allowed in a physical geographic area, such as A for agricultural (or airport or apartments), R for residential, C for commercial, I or M (industrial or manufacturing) and P for park or parking lots. These symbols are usually followed by a number to specify the level of use. For example, the common generalizations are R1 for a single-family home, R2 for two-dwelling units, and R3 for apartment complexes. In addition, some communities also designate another number to indicate certain square footage for that particular zone. For instance, R1-3 signifies a single-family dwelling with a lot size of less than 3 acres.
