The purpose of Marion's Zoning Regulations is to establish standards and procedures that:

  • Implement the Comprehensive Plan for the community;
  • Promote, preserve and protect the health, safety, morals and general welfare of the community;
  • Preserve architecturally, historically and archaeologically signification ares of the community;
  • Preserve environmental sensitive areas of the community;
  • Provide a balance between the rights of the landowners and the responsibility and authority of the City to review and regulate the subdivision of land and the installation of public improvements within the community; and
  • Provide for a balance between the rights of individual land owners and the economic, social and environmental concerns of the public.

       Editor's Note


Amendments to the Zoning Regulations are reviewed and recommended by the Planning & Zoning Commission to the City Council.  Amendments to the City Code are approved by City Ordinance.


Subdivision and zoning regulations are complex and copies of Ordinances should only be used as a reference or for initial planning.  We recommend contacting the Planning and Development Department to discuss requirements and options regarding a property before making firm plans or decisions.  It may be necessary to schedule an appointment for a pre-application meeting to discuss large or complex projects.

Staff assistance is recommended because there are circumstances where regulations may overlap or take precedents over others (such as “grandfathering”), conditions of rezoning may exist in certain areas, easements need to be identified, or a special district may exist (such as a historic district).

If the zoning classification of a property does not allow a desired use or proposed development, plans will need to be altered or a rezoning request may be submitted. In some situations a zoning variance request may be the way to proceed forward with a project.

Investment decisions based on misinterpretations of the Subdivision / Zoning Code or on the assumption that City Council, Planning and Zoning Commission or the Zoning Board of Adjustment may approve a rezoning or variance request may result in unnecessary expenses and ownership of property no longer desired.
