Required Inspections

After receiving notice to proceed, but prior to commencing work, the applicant must notify the City’s Inspection Dispatch at (630) 420-6100, Opt. 1 and schedule a pre-project inspection. Additional inspections may be required depending on the scope of work. After all work is completed, the applicant must notify the City and schedule a post-project inspection. Failure to schedule required inspections will cause the applicant to forfeit their grant award.

Time of Funding

After the renewable energy project is completed and the applicant has scheduled and passed a post-project final inspection, the applicant will submit a signed certification that the project has been completed, along with invoices, receipts and other documentation, by email to Bernie Saban at

The City will verify that all work and inspections have been completed, review the final application materials and issue the project reimbursement to the recipient.
