Replacing a water heater in Naperville.

86%Heat with utility gas
75%Single-family homes
The median home was built in 1990. A first or second replacement is common in homes this age.
86% of homes heat with utility gas, so gas water heaters with existing venting are common here.

LOCAL CONDITIONS
What’s different in Naperville.
The city runs its own electric utility
Because Naperville has its own electric utility, ComEd rebates don't apply to electric water heaters here. The utility's energy efficiency page sends residents to Nicor Gas rebates for gas water heaters. It lists no city water heater rebate.
Fee schedule is from 2019
The city last updated its home permit fees on Feb. 1, 2019 (Ord. 18-145). There is no line for water heaters. A similar special permit, such as one for a water softener, costs an $18 clerical fee, a $26 permit fee and $44 per inspection ($88 total).

PERMITS & LICENSING
Permits and licenses in Naperville.
Permits and who issues them
Naperville's permit guide says new water heaters, including a switch in power source, need a permit. Replacing a unit with the same type does not. When you do need one, you apply and pay for the plumbing permit in the city's Civic Access portal.
Plumbers need a State license. Plumbing contractors include their State contractor registration with each permit application. Naperville doesn't appear to have its own plumbing license.
