About Annexations

Voluntary annexations of unincorporated Johnson County property into the City of Olathe require approval of the City Council and, in specific situations, the approval of the Johnson County Board of County Commissioners. In order for a property to be annexed into the City, the property owner must request via written petition that the City Council annex the property.  Copies of the petition forms (Individual / Partnership / Corporate) are available on the City's website. The petition must be accompanied by the property legal description and a map showing the location of the property.  If the property does not have a boundary that is contiguous with the City boundary, then the Johnson County Board of County Commissioners will also have to approve the annexation of the property. 

The City of Olathe has written agreements with its surrounding cities (DeSoto, Gardner, Lenexa, Overland Park, and Spring Hill). These agreements establish the City's "planning area," which is the City's ultimate boundary limit (Map). The inter-local agreement states that the City of Olathe will not accept annexation petitions from owners of property outside of the City's planning area and that neighboring cities will not accept annexation petitions from the owners of property within the City's planning area.
