Building Permitting Information
Community Development is Transitioning to E-plan Reviews!
Iplan Table
New Iplan Table

Community Development now has an electronic plan review capabilities! We invite professional architects and engineers to submit plans in electronic form. Submittals should be PDF, with the ability to add an approval stamp, or Bluebeam compatible.  

As this is a new process for us, we welcome your professional input and suggestions. Please note that the Warrenville Fire Protection District will still require one set of paper submittals to conduct fire protection reviews. 

Please note that plans intended for committee members are still required to be submitted in paper format along with an electronic version for staff review. 

Electronic submittals can be attached to out e-permit application.

One of the goals of the Building “Division is to assure an accurate and efficient review process for all construction projects submitted to this office. In order for our staff to properly review and approve a project, certain documents are required: most requirements can be found in one of our many project information guides, available at City Hall or online. We understand your project is important to you and that you want to proceed with it right away. The list above contains the top ten reasons permit approvals are delayed in our office. Details are important and the staff here cannot make assumptions. When these items are missing or lacking detailed information, the staff is required to notify the applicant of the missing or incomplete items. When that occurs the application process starts over, including placement of the review order.
