Utility setup in McKinney, TX requires knowing more than just your zip code. Your specific street address dictates which companies can serve your house and how your monthly bills are structured.

A house inside the main city limits usually means straightforward municipal water and an open choice of electricity providers. Move out toward the newer subdivisions or the city’s edges, and you might find yourself in a utility district with a separate tax rate, or an electric cooperative where rates are fixed and shopping around isn’t an option.

Key Takeaway

For most homes inside McKinney city limits, the City of McKinney handles water, sewer, and trash, and you choose your own electricity retailer on Oncor’s lines. Check the specific address first, though: some McKinney-area homes are in a utility district or co-op territory where the bill and your choices change. With single-family homes taking a median 65 days to sell, you usually have time to ask the seller for a year of bills before you commit.

Who This Guide Is For

You are buying, selling, or renting a home in McKinney and need to know which companies will serve that specific address and what the monthly bills will realistically look like before you commit.

Why Utilities in McKinney Depend on the Address

The utility bills you inherit are set by the address, not the city name. Service-area boundaries don’t follow city borders cleanly, and with 4.3 months of supply on the market, buyers have room to confirm every provider and get a year of real bills before the option period ends.

Your location determines the water provider, city versus a municipal utility district (MUD) or special utility district (SUD), and whether you have access to Texas’s open electricity market or are locked into a cooperative. You can review the McKinney zip codes guide to see how different parts of town compare.

How to Narrow Down Your Utility Setup

Four specific questions determine what services your new home uses.

First, is the address inside McKinney city limits and on city water, or is it in a MUD or special utility district? Second, is it in Oncor’s service area, where you shop retail plans, or in an electric co-op’s territory? Third, is it a townhouse or HOA community where dues may cover water, trash, or other services? Finally, how many days until you get the keys?

Those four answers tell you exactly who to call and what to schedule first.

Who Provides Water and Electricity in McKinney

Water and electricity vary the most by address in Collin County, and they drive the largest share of your monthly household operating costs. Because service territories overlap across the region, assuming a provider based on a nearby neighborhood can lead to billing surprises. Verify both the water source and the electric grid for your exact lot.

City of McKinney Water vs. a Utility District

Inside city limits, the City of McKinney bills water, sewer, and usually trash on one account. The city buys its treated water wholesale from the North Texas Municipal Water District, which uses Lavon Lake as its primary raw water source. Some addresses in the McKinney area fall outside this standard setup and are served by a municipal utility district (MUD) or special utility district (SUD).

You can confirm the water provider for the exact address using the TCEQ/PUC service-area lookup, or simply ask for the seller’s latest water bill. If you’re looking at a master-planned community like Trinity Falls, ask the seller or builder whether the home is in a MUD. Private wells are uncommon for typical subdivision homes, but they do exist on rural acreage outside city service. If a listing has one, ask for a recent water test and the well’s service records.

A MUD address carries a meaningful extra tax rate and a different water rate structure. You won’t see it in the list price, only on the tax statement and the water bill, so get both before the option period ends. The moving to McKinney guide has a broader look at property taxes.

Oncor Service Areas vs. Electric Co-Ops

Most McKinney addresses run on Oncor’s wires, placing them in the competitive Texas electricity market. You choose a retail electricity provider and plan; Oncor delivers the power and handles outages. You can compare available plans on the state’s Power to Choose website.

When shopping for a plan, pull the seller’s highest summer month in kilowatt-hours (kWh) off their bills and compare each plan’s price at the nearest Electricity Facts Label usage level (500, 1,000, or 2,000 kWh) rather than relying on the headline rate. Some addresses on the city’s edges are served by an electric cooperative instead, such as CoServ Electric or Grayson-Collin Electric Cooperative. In co-op territory, you can’t shop retail plans on Power to Choose; the co-op is your provider and sets your rate.

The open market cuts both ways. Advertised low rates often apply only at one specific usage level, and variable plans can spike during a summer heat wave. In co-op territory, the billing structure you inherit is the one you keep.

Natural Gas, Trash, and Recycling in McKinney

The City of McKinney provides once-a-week fully automated curbside collection for both trash and recycling through its contracted hauler, Frontier Waste Solutions. Residents must set out their gray trash and blue recycling carts by 7 a.m. on the scheduled collection day. Bulky item pickup works differently: residents get up to 12 free bulky item collections per year, requested by noon the business day prior.

In HOA communities, confirm whether trash is billed by the city or arranged directly by the association.

Atmos Energy provides natural gas service to neighborhoods where homes are piped for it. Since some newer builds are entirely electric, check the property to see if it uses gas appliances. A gas account means a second setup deposit and a minimum monthly base charge, even in summer when the furnace is off.

Internet Providers in McKinney

Internet availability is determined street-by-street. Check your exact address on the FCC National Broadband Map, because fiber lines and high-speed cable don’t cover every neighborhood equally. A newer subdivision might have only one wired option; an older street may lack fiber entirely.

If you work from home, confirm actual service speeds with providers before closing. Don’t assume the provider you used in a previous city will offer the same tier of service at a new address.

How Much Utilities Cost in McKinney

Effective October 1, 2026, City of McKinney residential water rates inside city limits are tiered, starting with a base monthly charge of $21.60. The usage rate is $5.45 per 1,000 gallons for the first 7,000 gallons, rising to $7.50 for the next tier, up to $11.40 for usage above 40,000 gallons. Sewer service adds a minimum monthly rate of $31.20, calculated using your winter quarter average consumption.

For electricity, Texas’s average residential price was 15.88¢ per kilowatt-hour in July 2026. That’s a useful benchmark when estimating cooling costs, though what you pay depends on the plan you select and how much you run your AC.

To build a realistic monthly budget, total the seller’s 12 months of electric, water, and gas bills and divide by 12. Note the summer peaks separately, because cooling dominates North Texas utility bills. The cost of living in McKinney guide shows how these bills fit into a complete household budget. Larger homes cost more to cool, so checking the price-per-square-foot figures of available properties will help you estimate the operating footprint of your next house. The pros and cons of living in McKinney help put these monthly costs into perspective.

Summer Water Use and Watering Rules

The city is currently in its summer water conservation plan, which prohibits outdoor watering between 10 a.m. and 6 p.m. Outdoor watering is permitted on your trash day and three days later if necessary, and the city asks customers to reduce irrigation watering by two minutes per zone. Additional restrictions may apply depending on the ability of McKinney and the North Texas Municipal Water District to meet water demands.

Irrigation is usually what pushes summer water bills into the higher pricing tiers. Ask the seller for their irrigation controller settings and a copy of their summer water bills before you close. If you want to review local water quality, the city’s annual water quality report is the place to start.

How to Set Up Utilities When You Move to McKinney

For residential service, the City of McKinney charges a $200 regular deposit, plus a high-risk deposit if applicable. A connection fee of $50 applies during regular business hours, or $100 for same-day or after-hours service.

Roughly two weeks before you move, confirm the specific providers for your address and start your city water, sewer, and trash accounts with the start date set to your closing day. Then pick an electricity plan or contact the local co-op and set your switch date. From there, schedule your gas and internet installations.

Sellers should schedule their stop dates for the day after closing so the home doesn’t lose power during the final walkthrough. Ask each provider whether a deposit applies and whether a letter of credit history waives it. If you need help, Bale Real Estate Group can request bills and provider details from a seller during the option period, and the buying process guide has a full closing timeline.

Utility Questions to Ask Before You Buy

Ask the seller for 12 months of electric, water, and gas bills before the option period ends. Ask for the water provider’s name and whether the home is in a MUD, which you can verify on the property tax statement. Find out who the current electricity provider is and whether the seller is on a fixed-rate contract and when it ends, since that contract stays with the seller, not the house.

Ask whether gas is piped to the home and request the current irrigation settings for the lawn. For townhouses, which sell for a median $370,004 (based on 22 sales, so treat with caution), ask the HOA which services the dues cover.

A surprise MUD tax or unexpectedly high summer bills give you a fair reason to negotiate, particularly given the 4.3 months of supply currently on the market.
