The Unified Development Ordinance of St. Charles County is intended to promote the health, safety, comfort, and general welfare of the County's population; to secure coordinated land use; and to facilitate the adequate provision of public improvements.  This outline is intended to serve as a guide to the processing procedures associated with changing existing zoning district designations or for the development of property.  Detailed information concerning the processing steps involved herein can be found in the St. Charles County Unified Development Ordinance (UDO), Section 405.535, and at the St. Charles County Planning and Zoning Division Office.

Applications for amendment, revision or change of the Zoning District Map of St. Charles County may be made by any owner, attorney, agent, representative, or contract purchaser who wants land to be rezoned.  If such application is made by someone other than the owner, he shall enter upon the application the name and current mailing address of the owner.  Satisfactory evidence of ownership shall be provided at the time of application.  Such application shall be made upon forms prescribed by the Planning and Zoning Commission and duly filed with the Secretary of said Commission.

  • Identification of the Property.  Your first step in seeking a rezoning is to discuss your proposal with a St. Charles County Planning and Zoning Division staff member.  You can stop by the Planning and Zoning Division at 201 N. 2nd Street, Suite 420, St. Charles, Missouri  63301, or telephone us at 636.949.7335.  At this time the staff will advise you on the County's current zoning for the property and future land use plans for the immediate development area, and other factors that may affect the site in question.
  • Applying for the Rezoning. To file the application, you will need to bring the following items, along with your application form, to our office: 
  • A legal description of the property to be rezoned.
  • A recent certificate of title or deed to the property showing ownership.
  • A filing fee in the amount shown below, as controlled by the acreage:
Up    to   4.99 acres 


5.00 to 19.99 acres


20.00   to 49.99 acres


50.00 to 74.99 acres


75.00 to 99.99 acres


100 acres or more


  Immediately upon receipt of such applications which include all items listed above, the Divison of Planning and Zoning shall note thereon the date of filing and make a permanent record thereof.  (If paying by check, please make the check payable to St. Charles County Planning and Zoning Division.)     
  • Placement on the Agenda.  A County Planning and Zoning Division staff member will then review your application to make sure all of the necessary items have been furnished.  You will be given an application number and a place on the Planning and Zoning Commission Public Hearing Agenda.  There is usually a 4 to 8 week period between the filing of your application and the date of the Public Hearing.  This period of time is due to a required period for legal advertisements, time to prepare and mail notices of the hearing to nearby property owners, and other administrative details.  Check with the Planning and Zoning Division for the deadline dates.
  • Public Hearing.   At the Public Hearing the applicant for rezoning or his/her representative will address the County Planning and Zoning Commission.  This Commission is made up of 10 members.  When speaking to this body, explain exactly what you propose to do with the property and how your development will relate to the immediate area.  Please keep your comments to the point. After you speak, the Planning and Zoning Commission may ask you questions and then other citizens are permitted to speak for or against your proposal.  After all citizens have spoken, you will be given an opportunity for a rebuttal period.  Please keep your comments directed to the rezoning proposal, and answer questions raised by the speakers.  Again, please keep your rebuttal brief and to the point. 
  • Planning & Zoning Commission Recommendation.  A recommendation will be made during the Regular Meeting following the Public Hearing, unless voted to be tabled by three (3) Commissioners for additional review and/or information.  After a recommendation is rendered by the Commission, the application will then be forwarded to the St. Charles County Council.
  • Governing Body Approval or Denial.  The Planning and Zoning Commission's recommendation to grant or deny the application will be forwarded to the County Council approximately two weeks after the Regular Meeting date.  The final decision will be made by the governing body at a later date. 
  • Protesting a Rezoning.  A written remonstrance/protest can be filed with the County Registrar against a rezoning application by property owners within 1,000 feet of the rezoning.   In case of written protest (legal remonstrance) against any proposed change, revision, or amendment signed and acknowledged by thirty percent (30%) of the owners of real property within one thousand (1,000) feet of the parcel of land for which the change, revision, or amendment is proposed, and filed with the County Registrar.  When filing the remonstrance/protest with the County Registrar the signatures must be notarized, and if the land is owned jointly, as husband and wife, both must sign the protest.
    Cities having in effect zoning within one and one-half miles of the proposed rezoning may file a Resolution in protest of the proposed rezoning. A Resolution by a City Council or Board of Trustees should be filed with the County Registrar. 
    When a valid remonstrance or resolution is filed against a rezoning application, the favorable vote of at least 5 of the 7 members of the County Council is required to pass the rezoning.
