Courtesy Review
Applicant must provide 15 sets of all applications, letters, drawings, Plats of Survey and related information. If legible, these documents should be submitted in 8-1/2" x 11" or 11" x 17" format. All documents should be compiled into stapled, paper-clipped, or rubber banded sets suitable for agenda packets.

Proof of Ownership or a Letter from the Current Property Owner(s) authorizing the Applicant to Present Plans for the Property must be submitted.

It is important that copies of the plats of survey and drawings (drawn to scale) accurately represent the property as well as all related structures.

The property address must be clearly marked to enable the Plan Commission/ZBA members and Staff to easily locate it. In the case of vacant land, a detailed description of the exact location must be provided.

If this information is not received by the specified time the request will be moved to the next meeting date - no exceptions.

Review and Approval Process
In order to receive approval for any new development, redevelopment, subdivision, zoning ordinance amendment, special use, variation, planned unit development, or re-zoning, an application must be filed. Upon receipt of a completed submittal, City Staff will review the proposal to ensure it meets the requirements and intent of the applicable City Codes and Ordinances. It is then forwarded to the Plan Commission (PC) and/or Zoning Board of Appeals (ZBA). The PC/ZBA reviews the project and makes a recommendation to the City Council. If a Public Hearing is needed, the process will take approximately three months. The ZBA makes final decisions on minor amendments. Typically, there are five weeks between when the Plan Commission makes a recommendation on a development and the when the City Council takes final action.

Warrenville Fire Protection District
The Warrenville Fire Protection District is responsible for review and approval of all non-single family related building and occupancy permits and for approving all Fire Alarm and Sprinkler system drawings.

A Variance is required when a proposed project does not conform to certain of the standards and/or requirements in the City's Zoning Ordinance. The purpose of the Zoning Ordinance is to improve and protect the public health, safety and welfare of the residents of the City. The literal application of the provisions of the Zoning Ordinance may create hardships or practical difficulties. The City recognizes "Major" and "Minor" variances. The Community Development Director or a member of his staff can assist you in determining whether yours is a major or minor variance. A Minor variance is a modification of the provisions of the Zoning Ordinance of 10% or less. Refer to the Section seven of the Zoning Ordinance or contact the Community Development Department to review in further detail. A Variance requires a Formal Public Hearing. The Zoning Board of Appeals holds a Public Hearing and provides a recommendation to the City Council on major variances, the City Council then makes a final decision. The ZBA makes final decisions on minor amendments.

The ZBA may recommend, and the City Council may grant variances from the provisions of the Zoning Ordinance. In recommending or granting approval or conditional approval of a Variance, the ZBA and City Council shall prepare written findings of fact that all of the conditions below apply to the application:

  1. Special Circumstances: Special circumstances exist relating to the physical character of the property that are peculiar to the property and that do not apply generally to other properties in the same zoning district. And these circumstances are not of so general or recurrent a nature as to make it practical to provide, in the form of an amendment to this Ordinance, a general rule to cover them.
  2. Hardship or Practical Difficulties: Because of these special circumstances, the literal application of the provisions of this Ordinance would, without a variance, result in unnecessary and undue hardship or practical difficulties for the applicant, as distinguished from mere inconvenience.
  3. Not Resulting from Applicant Action: The special circumstances, practical difficulties, or hardship that are the basis for the variance have not resulted from any act, undertaken subsequent to the adoption of this Ordinance or any applicable amendment thereto, of any party with a present interest in the property.
  4. Reasonable Use and Return: Without the requested variance, the property cannot yield a reasonable return, or cannot be reasonably used consistent with the intent of the zoning district and the use of other properties therein, but the purpose of the variance is not otherwise to increase the return from the property or to confer special privileges not ordinarily enjoyed by other properties in the same district.
  5. Not Alter Local Character: The variance will not alter the essential character of the locality or substantially impair public safety or welfare or property values in the area.
  6. Minimum Variance Needed: The variance approved is the minimum required to allow reasonable use and enjoyment of the property.
