Ellenwood is unincorporated and spans DeKalb, Clayton and Henry counties, so the permit for a water heater replacement comes from whichever county your address is in. Many homes here were built in the 2000s, and their original heaters are now reaching the end of their run. Call the number on this page to be connected with a local plumber in Ellenwood.

What happens when you call
The call connects you with an independent plumber who covers Ellenwood. Tell them which county your address is in if you know it, along with the heater's fuel, size and age. If it is leaking, they will walk you through the shutoffs. They then inspect the installation and price a replacement, including the county permit. Because the rules differ by county, a plumber who regularly works across the DeKalb, Clayton and Henry lines can save you a round of phone calls.
Cost factors
- Gas or electric, tank size and efficiency
- Tankless or heat pump upgrades if you want them
- Venting, gas connector and valve condition
- Pan and drain for attic or closet installs
- County permit requirements, which differ by county
- Disposal of the old heater
Ellenwood conditions
Because there is no city government, everything runs through the county. Water and sewer come from DeKalb County Watershed Management, Clayton County Water Authority or Henry County Water Authority depending on the address. Confirm yours from your water bill.
Permits differ too:
- DeKalb side: DeKalb County Planning and Sustainability, Permits, Plan Review and Inspections, 178 Sams Street, Decatur (404-371-2155, option 3). Plumbing permits must be submitted by a plumbing contractor, not the homeowner, through the county e-Permitting Portal.
- Clayton side: Clayton County Community and Economic Development, Building Permits, 121 South McDonough St., Jonesboro ((770) 477-3569).
- Henry side: Henry County Building Department through the SagesGov portal ((770) 288-6051). Confirm how stand-alone trade work is handled.
Only about 16.5% of houses in the 30294 ZIP were built before 1980, so most heaters here are in newer subdivisions, often in garages or attics. Atlanta Gas Light is the expected gas pipe utility, though not confirmed for the ZIP. If you smell gas, leave first, then call 911 and Atlanta Gas Light at 877.427.4321.
Checklist before the plumber arrives
- Check your water bill to see which county utility serves you
- Clear space around the heater
- Know where the main shutoff is
- Have the label photo ready
- Note whether the heater is in the attic, garage or a closet
- Mention any past leaks or relief valve drips
