Set by local rules
Do you need a permit for Water Heater in Boone County?
In Illinois, there is no single statewide rule for a Water Heater; whether you need a permit is decided locally in Boone County.
There is no statewide plumbing code, so the rule is set locally, but most Illinois jurisdictions require a plumbing permit to replace a water heater. Chicago is a notable exception: same-for-same residential replacements in buildings up to four stories are exempt. Because Illinois leaves this to local jurisdictions, the reliable answer comes from Boone County Building Department. Zoning setbacks apply either way.
