Set by local rules
Do you need a permit for Water Heater in Toole County?
In Montana, there is no single statewide rule for a Water Heater; whether you need a permit is decided locally in Toole 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 Toole County Courthouse. Zoning setbacks apply either way.
