Replacing a water heater in Lemont.
Lemont's pages don't say if replacing a water heater with the same type needs a permit, so call the Building Department to check. ComEd supplies power, Nicor Gas supplies gas, and the village softens its own deep-well water. Permits and contractor licenses are all handled online, and plumbers pay no village license fee.

PERMITS & LICENSING
Permits and licenses in Lemont.
Permits and who issues them
Since August 29, 2022, Lemont has taken building permit applications, contractor licenses and inspection requests only through its online permit portal. The pages we checked don't say whether a same-type water heater replacement needs a permit. Ask the Building Department (permits@lemont.il.us, 630-257-1580).
Contractors need a village license before they start work. General contractors and subcontractors pay $100 flat. Plumbing, electrical, irrigation, fire alarm and sprinkler trades pay no license fee. Contractors must meet the insurance rules, and working without a license gets a citation.
