Water Heater Replacement in Greenwood Village, CO

Greenwood Village homeowners usually replace a water heater when the tank starts leaking, the hot water runs rusty or short, or repairs on an older unit stop making sense. The city lists water heater replacement among residential projects that require a building permit. Call the number on this page to be connected with a local plumber in Greenwood Village.

Does Greenwood Village require a permit for a new water heater?

Yes. Community Development's Building Permits & Inspections group lists water heater replacement and other plumbing work among residential projects that need a permit. Applications go through the city's Online Access Portal, and questions can go to 303-486-5783 or comdev@greenwoodvillage.com. The city also requires plumbers working here to hold a Greenwood Village contractor license, so it's fair to ask anyone you hire whether they're registered with the city before work starts. A plumber who works here regularly will already have that sorted.

Which water provider serves my house, and does it matter?

It depends on the address. Denver Water runs the system directly in the City of Greenwood Village Total Service area, while Southgate Water District and Cherry Creek Village Water District serve other parts of the city using Denver Water supply. The city publishes Water Districts and Sanitation Districts maps so residents can look up their provider. Denver Water's 2026 report lists average hardness around 105 ppm, ranging from about 55 to 124 ppm. That's moderate, enough for some sediment to collect in a tank over the years, so flushing annually helps a new heater keep its capacity.

What's involved in replacing a heater in a larger home?

Bigger houses often have more bathrooms, longer pipe runs and larger soaking tubs, so the replacement is a good moment to rethink capacity. Some owners move to two heaters, a larger tank, a tankless unit or add a recirculation line to shorten the wait for hot water at distant fixtures. Each option affects gas line sizing and venting, which a plumber should check before quoting. If the heater sits in a finished basement, a drain pan with a proper outlet is worth including. Xcel Energy supplies gas in the city; if you ever smell gas, leave the house first, then call 911 and Xcel at 1-800-895-2999 from outside.

A local note

Because providers vary across the city, the water district on your bill, not the city, is who to call for a shutoff at the curb or a main break. Keep that number handy alongside the heater's model and age when you call for quotes.

Water Heater Replacement questions in Greenwood Village

Does a water heater replacement here need a permit, and who issues it?

Yes. Greenwood Village lists water heater replacement among residential projects that need a building permit, applied for through the city's Online Access Portal. Plumbers must also hold a city contractor license.

How do I find out which water provider serves my address?

Greenwood Village is split among Denver Water's Total Service area, Southgate Water District and Cherry Creek Village Water District. The city's Water Districts map shows which one serves you.

What size should the replacement tank be?

Larger homes with several bathrooms may need more capacity than the old tank provided. A plumber can size a bigger tank, a second unit or tankless based on how you use hot water.

Can the new heater go in a different location?

Often, yes, but moving it adds water lines, venting for gas units and a drain. The relocated install still needs the city permit.
