A permit is required to install, operate, erect, construct, reconstruct, alter or add a piece of regulated equipment or area as defined in the Chicago Municipal Code, Section 11-4-610. Regulated equipment or area means “any combustion equipment, pollution control device, process equipment, or process area.” In general, this refers to equipment and areas that have a potential to emit any air contaminant into the atmosphere. Neither the size of the facility nor the amount of the air contaminant has any bearing on whether or not you need a permit.
If you are uncertain as to whether a permit is needed for the activity you wish to perform, read Frequently Asked Questions about Air Pollution Control Permit.
An Architectural Surface Cleaning Permit is also required for sandblasting, grinding, and chemical washing.
Please note, CDPH will no longer accept permit applications or payments by mail or walk-in at any location. All permits must be applied for online on the City of Chicago Permit Portal at https://ipi.cityofchicago.org/Profile/
