Do I need a permit for water heater replacement in Gurnee?

Permit required

Yes. In Illinois, water heater replacement generally requires a permit, and Gurnee is no exception.

Most Illinois jurisdictions require a permit to replace a water heater, and the work must be done by an Illinois-licensed plumber under the statewide Illinois Plumbing Code. Many local codes require a temperature and pressure relief line, proper venting, and seismic or expansion-tank provisions per the adopted code. Gurnee lists water heaters as their own permit, so replacing a water heater requires a permit and, per State of Illinois rules, the work must be performed by a licensed plumber registered with the Village. Gurnee requires a written, notarized letter of intent from the licensed plumber on company letterhead giving the job address and full scope of work, plus a current IDPH Plumbing Contractor's Registration. If the heater is gas-fired, the fuel-gas connection engages Gurnee amendments that prohibit corrugated stainless steel tubing. File the permit through OneStop at onestop.gurnee.il.us.
