What water and energy rebates does the City of Mesa offer?

The page lists seven programs. Three are about water, one is about gas appliances, and the rest are electric or aimed at other customer types:

• Natural Gas Appliance Rebate, for Mesa natural gas customers.
• Residential Grass-to-Xeriscape and Tree Bonus Incentive Program, described as "Incentives available for residents to reduce water use, increase efficiency, and save money."
• Water Management for Commercial Customers and Water Management for HOAs, for those account types.
• Electric Vehicle Time of Use Rate, Renewable Energy Service Rider and Electric Smart Peaks Program, which are electric programs.

The page doesn't list a toilet, showerhead or faucet rebate for homeowners. If you're comparing cities, our page on Phoenix's water-saving rebates shows what Phoenix lists, and Scottsdale's 2026 water rebates covers the next city over.

### Which program fits your house?

Sort the menu by what you own and what you bill for:

• You have a gas water heater or are buying one. Look at the gas appliance rebate, and check that Mesa, not Southwest Gas, is your gas utility.
• You have a single-family home with a grass yard. Look at the grass-to-xeriscape incentive. Start with the application, not the shovel.
• You manage an HOA or a commercial property. Mesa has separate Water Management pages for those account types, so don't use the residential rules.
• You want to cut your electric bill. Mesa's page hands that to SRP and the state.

Mesa's Natural Gas Appliance Rebate page lists "Natural Gas Water Heater - $25 rebate" and "Natural Gas Pool/Spa Heater - $50 rebate." It applies to Mesa gas customers only. The page says "Southwest Gas customers are not eligible." The water heater must be tank style, at least 30 gallons, new, and bought by the homeowner, and the credit arrives on your bill after approval.

That's the short version. The full eligibility list, the paperwork and the permit and gas meter cautions are on our page about whether Mesa's gas appliance rebate covers a water heater. If you're weighing a switch, start with gas versus electric water heaters.

Mesa's page says "Take advantage of our incentive of up to $2,100 to replace your grass with a low-water-use Xeriscape!" The amount depends on how much grass you remove and whether you add trees:

• 500 to 999 square feet: $1,000, or $1,050 to $1,100 with one or two qualifying trees.
• 1,000 to 1,499 square feet: $1,500, or $1,550 to $1,600 with trees.
• 1,500 square feet and above: $2,000, or $2,050 to $2,100 with trees.

Those tiers are Mesa's. The rules matter more than the amounts.

Start with the basics:

• The applicant must be the current owner of a single-family home and a Mesa water customer.
• It is for future projects. Mesa's program page says "Complete your application BEFORE you start your conversion project!" and "No work can be done before an approval to proceed is given."
• "Funding is limited and on a first-come, first-served basis."
• One incentive is allowed per property in a 3-year period, and the minimum is 500 square feet of grass.
• "Spray irrigation and non-pervious materials (such as black plastic sheeting) are not permitted in the converted area."
• Artificial turf alone doesn't qualify. The new plants must reach at least 50 percent canopy coverage at maturity.

The city gives you six months to finish after approval. Then come the fine print. Here are more conditions from the program page:

• The grass has to be alive. The page defines healthy as "routinely irrigated and manicured with an average coverage of 70 percent (70%)."
• "Any grass areas watered by wells or flood irrigation water are not eligible." Only landscapes watered by potable water that can be measured through a city water meter qualify.
• New plants must come from the Arizona Department of Water Resources low-water-use plant list, and the new landscape needs mulch at least 2 inches deep.
• Homeowners in an HOA "must ensure that the new landscape complies with HOA Covenants, Codes & Restrictions (CC&Rs)."
• A W9 form is required after the project is complete, and the city issues a 1099.
• The Tree Bonus, up to $100 more, requires one or two low-water-use trees, and the page says "Trees planted prior to or after the completion of an approved conversion project do not count."

Homes built within the past year of the application date are ineligible. Mesa's Save Water Indoors and Out page describes the residential incentive as "up to $1,100," which doesn't match the program page's $2,100. Two pages, two numbers. That's why you confirm on the program page itself.

A grass-to-xeriscape project touches your irrigation lines, and that's where a plumbing surprise hides. Mesa's tree guidance says "Trees should be on a separate valve of the irrigation system for optimal watering amounts and frequency," and to "Call AZ Blue Stake 8-1-1 before digging to identify underground utility locations." Know where your own irrigation and water lines run, too, before anyone trenches. Our pages on drip irrigation repair and planning landscaping around plumbing lines cover that, and a meter check after the work confirms nothing got nicked. See how to do a water meter leak test.

Mesa's page also lists savings from other agencies. It says SRP "supplies electric service to about 90% of Mesa residents" and that SRP has rebates, tips and audits. It says "Southwest Gas services some Mesa residents" and points those customers to Southwest Gas for rebates. It mentions Arizona's tax credit for residential solar and Efficiency Arizona, "a rebate program for qualified households to install highly efficient appliances and HVAC equipment."

On the federal side, ENERGY STAR's tax credit page says "There are federal tax credits available through the end of 2025." As of 2026-09-29 that date has passed, so don't count on a federal credit without confirming it's still available.

Here's the play. Find out which utility bills you, pick the program that fits, confirm the current rules on the city page, and get approval before you start anything.
