Summary of Zoning Districts


All of the unincorporated areas of Cochise County have been zoned. The purpose of zoning is to guide the development of land in accordance with the County’s Comprehensive Plan, and to promote the public health, safety and general welfare of the County’s residents. Zoning districts specify permitted land uses, minimum lot sizes, and certain site development standards such as setbacks and screening. Because Cochise County encompasses a large and diverse area, there are 34 individual zoning districts. However, for general purposes, the majority of these zoning districts can be classified into three broad groupings: Rural, Residential and Commercial/Industrial. 

Following is an explanation of the three general zoning categories, and a summary of the specific zoning districts that fall under each classification. Included is a brief summary of the permitted land uses and minimum lot sizes for each district. This summarized information is intended to be used as a guide only, and therefore is not a detailed listing of everything that is allowed in a particular zoning district. A complete description of each zoning district is available from the Planning Department upon request, in addition to copies of the Cochise County Zoning Regulations.

To determine the zoning district for a parcel, contact the Planning Division (520-432-9240) with the Tax Parcel I.D. number or assigned rural address.

Rural Zoning Districts

Approximately 90% of the unincorporated areas of the County are zoned RU (Rural). These districts allow residential uses on large acreage, as well as some other uses typically found in rural areas. In addition, a wide range of commercial and industrial activities are also possible as Special Uses, which require, on a case-by-case basis, a public hearing and approval by the Planning and Zoning Commission. 

Please note that general agricultural, ranching, mining and railroad activities are exempt from County zoning regulations by State law.

Residential Zoning Districts

There are a variety of residential zoning districts offering a wide range of housing types, lot sizes and densities. These include SR (Single-Household Residential), SM (Single-Household/Manufactured Home Residential), and MR (Multiple-Household Residential). TR (Transitional Residential) districts are subject to the requirements of the similar Residential Zoning District, for example TR-8 is treated the same as SR-8. As the name implies, TR districts are located at the fringes of developed areas and act as a transition zone between high-density urban and low-density rural lands.

For the purpose of clarifying residential uses, the following terms are defined as follows by the Cochise County Zoning Regulations:

Dwelling: Any building intended primarily for residential occupancy by one or more households, containing sleeping, cooking, and sanitary facilities.

Dwelling, Multiple-household: A single dwelling in a structure containing defined space for two or more households, with separate entrances, cooking, sanitary and sleeping facilities for each. Multiple household dwellings may include apartments, condominiums, townhouses, and multiplexes.

Dwelling, Single-household: A structure surrounded on all sides by open space and setback from the property line, intended for occupancy by one household. This definition includes site or factory-built homes, rehabilitated mobile homes and manufactured homes, but does not include recreational vehicles. A mobile home that has not been rehabilitated, as required by these Zoning Regulations, may be used for this purpose only if it meets the standards under these Zoning Regulations for a lawful non-conforming use.

Factory-built Building: A residential or nonresidential building including a dwelling unit or habitable room thereof which is either wholly or in substantial part manufactured at an off-site location to be assembled on-site and placed on a permanent foundation. Factory-Built Buildings are constructed to Building Code standards and are regulated by the Arizona Department of Housing. Factory-Built Buildings do not include manufactured homes, recreational vehicles, or mobile homes. A factory-built building used for residential purposes shall be considered a single-household dwelling unit.

Manufactured Home: A structure built in accordance with the National Manufactured Home Construction and Safety Standards Act of 1974 and Title VI of the Housing and Community Development Act of 1974 and as amended. Does not include mobile homes, factory-built buildings, or recreational vehicles.

Mobile Home: A structure built prior to June 15, 1976 on a permanent chassis, capable of being transported in one or more sections and designed to be used with or without a permanent foundation as a dwelling when connected to on-site utilities. Does not include recreational vehicles, factory-built buildings, or manufactured homes.

Mobile or Manufactured Home Park: A site or parcel of land under single or unified ownership upon which three or more mobile homes, manufactured homes, factory-built buildings or a combination thereof, are set up as residences, regardless of whether the units are permanently occupied or offered as rental units. In Comprehensive Plan Category D Growth Areas designated Rural, six or more mobile homes, manufactured homes, factory-built buildings or a combination thereof shall be considered a mobile or manufactured home park.

Commercial/Industrial Zoning Districts

There are several districts established to accommodate business and industrial uses. These Commercial/Industrial zoning districts ranging from least to most intensive are NB (Neighborhood Business), GB (General Business), LI (Light Industry), and HI (Heavy Industry). A number of Special Uses are also possible in these zoning districts. Special uses must be considered on a case-by-case basis and require a public hearing before the Planning and Zoning Commission.

The commercial and industrial zoning districts are summarized as follows:


Permitted Uses*

Minimum Lot Size

NB (Neighborhood Business)
