Do I need a permit for water heater replacement in Wheaton?
Yes. In Illinois, water heater replacement generally requires a permit, and Wheaton 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. Wheaton requires a permit for a water heater, whether conventional or on-demand, and requires a room schematic showing clearances to walls and combustibles plus a water line bonding diagram. Water heater and water piping work is plumbing work that must be performed by an Illinois state-licensed plumber (state registration 055 and license 058) who is registered with the City of Wheaton. A gas-fired, non-high-efficiency unit also requires a combustion air calculation worksheet. Confirm the submittal list with the Wheaton Building and Code Department at 630-260-2050.
