Ag Areas Overview

Ag Areas – official known as “Agricultural Areas” can be established through local action under the authority found in the Agricultural Areas Conservation and Protection Act passed by the Illinois General Assembly in 1980.


Ag Areas offer one means of helping to maintain farmland for farming purposes. While the Ag Area designation is not a total solution in and of itself, it is another tool that may be used by landowners.


The development of Ag Areas is best accomplished in those areas which are strictly agricultural in nature and where landowners and county officials have an interest in preserving the land for farming. A minimum of 350 acres is required. It takes the commitment of both landowners and county government officials to make it happen.


Once established, the Ag Area remains in place for 10 years; with subsequent extensions of the designation each lasting an additional 8 years. Provisions are in place to allow individual parcels of property to be removed from, or added to, the area within those periods of time. Again, both the landowners and local government officials will have to agree on those changes making Ag Areas truly a joint effort by the public and private sectors.

Miscellaneous Facts on Ag Areas

  1. Size of an Ag Area

    1. Minimum – 350 acres

    2. Maximum – No Limit

    Implementation of an Ag Area

    1. Total implemented at the county level. Ag Areas are approved, modified, or terminated by the county board. The county state’s attorney should be consulted for legal advice when forming an Ag Area.

    2. Ag Areas are adopted for a 10 year period initially, and are renewable every 8 years thereafter.

    Land proposed for inclusion in an Ag Area

    1. Ag Areas should be as compact and contiguous as possible. The county board has the discretion as to what constitutes “compact and contiguous.” Municipal authorities may object to land within a proposed Ag Area that falls within 1 ½ miles of the corporate limits. If the county board receives such an objection, the Ag Area shall be modified to exclude the land within the municipality’s 1 ½ mile jurisdiction.

    2. No land may be included within an Ag Area without the consent of the landowner(s).

    Benefits of an Ag Area

    1. Protects landowners from local laws or ordinances which would unreasonably restrict or regulate normal farming practices, including nuisance ordinances. Provides protection from special benefit assessments (examples – sewer, water, light, and non-farm drainage assessments), unless the landowners are benefited. All special benefit assessments will continue, however, if they were imposed prior to the formation of the Ag Area. Protects land from locally initiated projects which would lead to the conversion of that land to other uses (examples – park, garbage dump, etc.).State agencies may take into account the existence of Ag Areas when selecting a site for a project; however, the Act does not prohibit these agencies from acquiring land in Ag Areas for development purposes. Ag Areas protect the integrity of farming operations.

    2. A County Board that adopts Ag Areas is declaring that agriculture is important to the community and local economy.

    Mineral Rights

    1. Agreements for the extraction of mineral resources in place before the creation of an Ag Area are exempt from the provisions of the Ag Areas Act.

    2. Mineral extraction pursuant to the Surface Coat Mining Land Conservation and Reclamation Act (1980) is considered to be a temporary land use and is therefore allowed within an Ag Area.

    Land ownership and Ag Areas.

    1. There are no restrictions on buying and selling land that is within an Ag Area.

    2. The Ag Area designation continues to exist regardless of a change in ownership.

  2. Use of land within an Ag Area.

    1. No land within an Ag Area can be used for other than agricultural production.

      • Agricultural production means the production for commercial purposes of crops, livestock, as well as livestock and aquatic products.

      • Agricultural production does not include portions of land used for the processing of crops, livestock, along with livestock and aquatic products.

    2. A house can be built on land in an Ag Area if a person who lives in the residence is actively involved with the farming operation (i.e., farm owner, operator, tenant, and seasonal or year-round hired workers).
