Set by local rules
Do you need a permit for Water Heater in Carter County?
In Montana, there is no single statewide rule for a Water Heater; whether you need a permit is decided locally in Carter County.
There is no statewide plumbing code, so the rule is set by your local jurisdiction, but virtually all jurisdictions require a plumbing permit to replace a water heater, even a same-for-same swap. Fuel changes or tankless conversions also need gas or electrical permits. Because Montana leaves this to local jurisdictions, the reliable answer comes from Carter County Planning & Zoning. Zoning setbacks apply either way.
