Open Burning Permits

Only dry, seasoned wood is to be burned at any time. It is a violation of the open burning ordinance to burn leaves, grass, rubbish or garbage, and/or any wood that is still green or has been freshly cut.

Residential fires that are less than two feet by two feet by two feet do not require a burn permit, they are allowable any day of the week, and must be continually supervised by someone over the age of 16. If placed in an approved container, the fire must be a minimum of fifteen feet from any temporary or permanent building and/or fence. If the fire is not in an approved container, it must be located a minimum of fifty feet from and temporary or permanent building and/or fence.

Residential fires (bonfires and large landscape fires) that are greater than two feet by two feet by two feet and up to five feet by five feet by five feet require an Open Burning Permit. These fires are only permitted on Fridays and Saturdays for a maximum of five consecutive hours and must be placed a minimum of fifty feet from any temporary or permanent building and/or fence. The approved Open Burning placard must be present and visible during the duration of the bonfire or large landscape fire.

To obtain an Open Burning permit, you must complete the Open Burning permit application and attach a site plan of the property indicating where the burning will take place and where the water source is located in relation to the burn site.  The property will be inspected before the permit will be approved.  Open burn application must be submitted to the Community Development Department a minimum of three business days prior to the scheduled open burning.  If you have any questions, contact Community Development at (630)393-9050.

Overweight / Oversize Vehicle Permit (Oxcart Permit System)

Sign Permit

An application for a sign permit must be accompanied with a completed Building Permit Application, two sets of Plat of Survey for ground signs, or Building Elevation Drawings for wall signs, two sets of sign drawings, and any other pertinent information (see Sign Regulations for details).

Special Use Permit

Most land uses are only allowed to operate in certain Zoning Districts. Some uses cannot be allowable generally in a particular zoning district, but may be allowed under special conditions. Such uses require Special Use Permit approval. Refer to the Section three of the Zoning Ordinance or contact the Community Development Department to confirm that the proposed land use is permitted at the specific site. Special Use Permit approvals require a Formal Public Hearing. The Plan Commission holds a Public Hearing and provides a recommendation to the City Council. The City Council makes the final decision on the petition.

In recommending or granting approval or conditional approval of a Special Use, the City Council and Plan Commission shall prepare written findings of fact that on the basis of the characteristics cited under Review of Special Uses Section seven of the Zoning Ordinance or changes to such characteristics that conditions to which the approval is made subject require the proposed use will be compatible with existing uses in the area, and with Permitted Uses in the zoning district, in the following ways:

  • Traffic - Any adverse impact of types or volumes of traffic flow not otherwise typical in the zoning district has been minimized
  • Environmental Nuisance - Any adverse effects of noise, glare, odor, dust, waste disposal, blockage of light or air, or other adverse environmental effects of a type or degree not characteristic of Permitted Uses in the zoning district, have been appropriately controlled
  • Neighborhood Character - The proposed use will fit harmoniously with the existing natural or man-made character of its surroundings and with Permitted Uses in the zoning district
    • The use will not have undue deleterious effect on the environmental quality, property values, or neighborhood character already existing in the area or normally associated with Permitted Uses in the district
  • Public Services and Facilities - The proposed use will not require existing community facilities or services to a degree disproportionate to that normally expected of Permitted Uses in the district, nor generate disproportionate demand for new services or facilities as compared with the Permitted Uses, in such a way as to place undue burdens upon existing development in the area
  • Public Safety and Health - The proposed use will not be detrimental to the safety or health of the employees, patrons, or visitors associated with the use nor of the general public in the vicinity
  • Other Factors - The proposed use is in harmony with any other elements of compatibility pertinent in the judgment of the commission or council to the particular Special Use or its particular location
