Commercial Requests will remain on file until granted. You must be a current Chicago Harbors Boater or have an active mooring application for the vessel you are looking to operate with on file in order to fill out a request. Please check our availability list online as well. Approval may require slip relocation. Filling out a request does not guarantee a Commercial Permit. Permits will be granted according to the Chicago Park District Code. If you receive approval for a Commercial Permit your paperwork must be submitted and permit paid for within the same boating season. If paperwork and payment is not received you will forfeit your Commercial approval and will need to reapply. All parties who do not have a valid commercial permit and operate illegally are subject to fines and revocation of their mooring permit.
