Underground Sprinkler System Resource Guide

When installing an underground sprinkler system, a permit is required.  Homeowners may install these systems; however, if you have hired a contractor to perform the work, the installation must be installed by a State of Illinois licensed plumbing contractor. 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."  You can verify if a plumbing contractor has a State license by contacting the Illinois Department of Public Health at 217.524.0791.  If you would like to install the system in the public parkway, a Right-of-Way Agreement must be submitted.  The Village's Legal Department will have the agreement recorded with the Cook County Clerk's Office and the original will be forwarded to the owner of the property.

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