Engineering Permit Inspections

The Engineering Inspections Webpage is intended to provide guidance and direction for Wilmette property owners, developers, and contractors seeking to request to schedule an Engineering inspection as part of their permitted development or construction project.  Inspections are required to ensure that the work being performed meets applicable codes and Village Engineering Standards.  It is the permit holder’s responsibility to call and schedule all required inspections.  All Engineering Inspections shall be scheduled a minimum of 24-hours in advance, and are subject to availability.  To schedule an Engineering inspection please call the Engineering Division at (847) 853-7660, and be ready to provide the following information:

  • Project Number and property address
  • Type of inspection being requested
  • Desired date and time range for inspection
  • Name and telephone number of person requesting the inspection

If your call is not answered, please leave a voicemail message; a clerk will return your call as soon as possible.  Requests for inspection must be confirmed over the phone; please do not assume that an inspection has been scheduled just by leaving a voicemail message.  Inspections will be scheduled Monday through Friday between 8:30 a.m. and 12:00 p.m. 

 

Inspection Types and Requirements

Please see below for a list of common inspection types, along with information and requirements pertaining to each of the inspections. Not all inspection types listed below may apply to all projects.  Please review your permit conditions for a listing of required inspections, and call the Engineering Division if you should have any questions.

 

Grading Inspections

  • Top of Foundation Inspection – An inspection of the top of foundation (T/F) shall require the contractor to be present on site, with an instrument set up and ready for use by the inspector to verify the proposed T/F.

  • Pre-Sod Grading Inspection – An inspection of the finely-graded site prior to placement of sod or landscaping. The site must be properly graded per the approved Engineering plan.  All grading requirements must be approved before sod will be permitted to be placed.  Placing sod and landscaping without an inspection may result in removing the sod and landscaping and properly regrading site to match the approved Engineering plan.
  • Final Grading Inspection – An inspection typically scheduled at the end of a project following completion of all grading and landscaping work. An as-built drawing may need to be submitted prior to this inspection, as may be specified in your Engineering permit conditions. It is at this point that a Tree-Canopy Compliance Review may also be conducted as may be required under your Engineering permit conditions.
