Commercial Addition Resource Guide

If you are planning to construct an addition to any commercial retail, industrial, office or restaurant a permit is required.  Plan reviews are conducted for these projects. All contractors working on the project must obtain a valid village Contractor's Business License.  The village does not license roofers or plumbers as these trades are licensed by the State of Illinois. You can verify if a roofing contractor is state licensed by visiting the website of the Illinois State Department of Professional Regulations.  To verify if a plumbing contractor is state licensed, please contact the Illinois Department of Public Health at 217.524.0791. Effective March 1, 2013, per 225 ILCS 320/37 (from Ch. 111, par. 1135 of The Illinois Plumbing License Law, "A letter of intent shall be included with all plumbing permit applications. The letter shall be written on the licensed plumber of record's business stationery and shall include the license holder's signature and, if the license holder is incorporated, the license holder's corporate seal. If the license holder is not incorporated, the letter must be notarized."  If we do not have a current copy of a roofer's license or plumber's license, we will ask that they submit a copy to us prior to permit issuance.

If you have any questions regarding the permit application, process, inspections, or requirements, please contact the Permitting Division of the Community Development Department at 847.923.4420.
