Replacing a water heater in Wentzville.
Wentzville's Building Division charges 0.50% of the job cost for small home permits, with a $35 minimum plus a $50 plan review fee. The city doesn't say whether a same-type water heater swap needs a permit, so call first. Every contractor needs a city license renewed each February, and homeowners can do minor work themselves with a permit. The PSC lists Ameren Missouri for both electricity and gas. City water mixes local wells with water bought through St. Charles County PWSD 2.
