After submittal, the staff will perform a zoning and building review. After the review, they will invoice a $150.00 processing fee and arrange for an inspection of the proposed re-occupancy area. Within several business days after the inspection, you will be provided with a summary of findings and a copy of the review comments. The summary of findings will be classified based on the following categories:

1. Approved - The category means that the building and/or space is in compliance with the codes, resulting in approval for occupancy.
2. Conditionally Approved - The category means that the building and/or space WILL be in compliance with the codes after all conditions/corrections noted on the Review and Summary Form are completed.
3. Denied - The category means the building and/or space is significantly non-compliant with the codes. Additional or new information will need to be provided, and/or a building permit may be required for re-occupancy. Guidance will be provided by the City of Wheaton Building Department regarding the next actions.

The summary sheet will also inform you of any additional permits or licenses that may be required from other City departments and/or governmental agencies. For example, the sale of food will require both a city license as well as approval by the DuPage County Health Department.

For new exterior signs, see our Signs Guideline.
