Replacing a Water Heater in Dawsonville and Dawson County

Does it need a permit?

In unincorporated Dawson County, yes: the County's building permits page says a plumbing permit is required for water heater replacement. Inside the city, the City's Planning and Zoning Department issues permits and performs inspections; ask it to confirm the requirement and the fee for your parcel. Either way, a replacement involves the relief valve piping, the connections and, for gas units, the venting and the gas line, all of which an inspector checks.

What it costs to permit in the County

The County's fee schedule, effective August 1, 2026, sets the residential trade permit fee. A failed inspection costs more the first time than later times, and starting before the permit is issued doubles the fee.

Questions to ask the installer

Is the new unit the same fuel and size, and will it fit the space? Is the relief valve discharge piped to an approved location? Is a thermal expansion tank needed? For gas, will the venting be checked and corrected? Is there a drain pan with a drain where the heater sits over a finished floor? Is haul-away included? Is the permit in the price, and who requests the inspection?

Get the answers in the written quote. They are the inspection items, and a quote that leaves them out is not comparable with one that includes them.

Tank, tankless or heat pump

Like-for-like replacements are simplest. A switch to tankless gas often needs a larger gas line and new venting. A heat pump water heater needs room, air and a condensate drain. A fuel switch involves the gas system, which is inspected. Ask for a price for each option, each including the permit, before deciding.

When it fails without warning

Shut off the cold supply valve above the heater and the power or gas. If it is leaking, open a hot faucet and drain the tank through its drain valve with a hose to a floor drain or outside. Then call for help. Even in an emergency, the permit should be filed; ask the plumber how they handle that with the City or County.

Signs of the end

Rusty hot water, popping or rumbling from the tank, moisture around the base, or a relief valve that drips are all signs an older heater is near the end. Replacing it on your schedule lets you compare quotes and file the permit ahead of time.

Choosing the size

Tank water heaters are sized by capacity and recovery rate, which together determine how much hot water is available in a busy hour. A household that runs out of hot water in the morning may need a larger tank or a faster recovery unit, not just a replacement. Tankless units are sized by flow rate and temperature rise; north Georgia winter groundwater is cold enough that the rise matters. Ask the plumber to size the unit for your household rather than matching the old one automatically.

Location affects the choice too. A unit in a garage needs protection from vehicles and, for gas, attention to ignition sources. A unit in a crawl space is exposed to cold and is hard to service. A unit in a closet over finished floors needs a pan and a drain. Replacement time is the cheapest time to move it, if moving makes sense.

Inside the city

Inside the city limits, Planning and Zoning issues permits and performs inspections. The City's inspection list says inspections are requested by email and that inspections on the day of the request are currently unavailable, so a planned replacement should be scheduled with that in mind. For an emergency replacement, ask the plumber how they coordinate the permit and inspection with the City after the fact.

Keeping the new heater working

Drain a few gallons from the tank once or twice a year to flush sediment, test the relief valve as the manufacturer recommends, and check the anode rod on a long-life tank. Keep the area around a gas unit clear. Note the installation date somewhere visible. These small steps add years to a tank.

Energy and safety notes

Set the tank temperature high enough for household needs and low enough to reduce scalding risk; many manufacturers ship units at a moderate setting for that reason. Make sure the relief valve's discharge pipe runs to a safe location and is never capped. For gas units, keep combustibles away and make sure the venting draws properly; a carbon monoxide alarm nearby is inexpensive protection. For electric units, the circuit should be sized for the new heater, which is an electrical question the installer should confirm.

Disposal of the old unit

Ask the plumber whether removal and disposal of the old water heater is included. Tanks are heavy and awkward, and scrap metal recyclers accept them, but most homeowners prefer the installer to take them away. Make sure the old unit is drained and disconnected safely, and that any gas line left behind is properly capped.

Water heater checklist

Confirm City or County. Get written quotes listing relief valve piping, expansion tank, venting and pan. Check the plumber's Georgia license with the Secretary of State. Confirm the permit. Be available for the inspection. Keep the permit, inspection result and the new unit's model and serial number.
