Isaias Contreras is a REALTOR® with Contreras Properties Group at Keller Williams Signature, working with buyers and sellers across Katy, Fulshear, and Richmond, TX. Katy is a suburban city west of downtown Houston that spans three counties — Harris, Fort Bend, and Waller — inside the Greater Houston Area of Texas. This guide breaks down what it actually costs to live there in 2026: housing, property taxes, utilities, groceries, and transportation, plus how those numbers compare to two nearby alternatives.

What Is the Cost of Living in Katy, TX?

The cost of living in Katy, TX is the total monthly and annual expense of housing, property taxes, utilities, groceries, and transportation in this three-county suburban city west of Houston. Katy sits within Harris, Fort Bend, and Waller counties in the Greater Houston Area of Texas. Its defining cost features are a median home price near $355,000, property tax rates above the national average, and the absence of any Texas state income tax.

How Much Does Housing Cost in Katy, TX in 2026?

Housing is the single largest line item, with a median home price of roughly $355,000 in Katy, TX as of mid-2026 according to Houston Association of Realtors MLS data. The broader range across Katy runs from about $330,000 to $410,000 depending on the subdivision and which data source you use.

That spread is wide because Katy is not one uniform market. Older established neighborhoods closer to the original city center price differently than newer master-planned sections built out toward the Grand Parkway. Newer construction with current finishes and larger lots pulls the top of the range; resale inventory from the early 2000s anchors the bottom.

What Are Property Taxes Like in Katy, TX?

Combined property tax rates in Katy, TX generally land between 2.0% and 2.5% of assessed value, which is the cost most buyers relocating from out of state underestimate. Because Katy spans three counties, your exact rate depends on which side of the county line your address falls on.

The main components stacking into that combined rate:

• Katy Independent School District: $1.1171 per $100 of valuation — the largest single piece (Katy ISD)
• City of Katy: $0.4250 per $100 of valuation for addresses inside city limits (City of Katy)
• County rate: varies across Harris, Fort Bend, and Waller counties
• MUD (Municipal Utility District): applies in many master-planned communities and can add meaningfully to the total

Not every Katy address carries a city rate. Plenty of homes with a Katy mailing address sit in unincorporated county territory, which changes the math. Always pull the actual tax record for a specific property rather than assuming a neighborhood-wide figure.

The offset is that Texas collects no state income tax. For a household earning a middle-to-upper income, that absence frequently outweighs the higher property tax burden compared with states that tax both.

What Do Utilities, Groceries, and Commuting Cost in Katy, TX?

Utilities in Katy, TX average roughly $195 to $210 per month for a typical single-family home, with summer cooling driving the peak. July and August bills routinely run well above the annual average, and a larger home with more square footage to cool will exceed this range.

Groceries in Katy track near the national average. Cost-of-living index trackers place Katy anywhere from slightly below to slightly above 100 overall depending on methodology, so treat any single index number with skepticism — the underlying baskets differ between sources.

Commuting is a genuine cost factor. The average one-way commute from Katy runs about 29 minutes, and households working downtown or in the Energy Corridor should budget for tolls on the Grand Parkway or Westpark if they use them daily. Two commuters with toll usage can add a real monthly figure that rarely shows up in cost-of-living calculators.

How Does Katy Compare to Fulshear and Richmond, TX?

Katy sits between its two closest suburban alternatives on price. Fulshear runs materially higher; Richmond sits close to Katy with slightly more room at the entry level.

If retail access and commute time matter most, Katy carries the advantage. If your priority is newer construction and you can absorb roughly $150,000 more at the median, Fulshear delivers that. Richmond is the closest substitute to Katy on price while still sitting inside Fort Bend County.

Why Does This Matter for Buyers and Sellers in Katy, TX Right Now?

The practical takeaway is that in Katy, TX the monthly payment is driven as much by taxes as by price. A buyer comparing a $355,000 home in a MUD district against a $370,000 home without one can easily find the cheaper house costs more every month. That reverses the instinct most buyers arrive with, and it is the single most useful thing to understand before touring.

For sellers, it means the tax and MUD profile of your neighborhood is part of your competitive position, not a footnote. If your section carries a lower combined rate than the comparable listing two miles away, that is a payment advantage worth surfacing in how the home is presented.

Looking forward, Katy's position between Fulshear's higher price point and Richmond's comparable one means it competes on convenience rather than on being the cheapest option in Fort Bend County. Buyers who value that convenience will keep supporting Katy pricing; buyers who don't have two credible alternatives within a twenty-minute drive.

What Do Buyers Most Want to Know About the Cost of Living in Katy, TX?

Is Katy, TX expensive compared to the rest of Greater Houston?

Katy, TX sits in the middle of the Greater Houston suburban range. Its median home price near $355,000 runs above Houston's urban core averages in some submarkets and below newer western suburbs like Fulshear. Where Katy costs more than average is property taxes; where it costs less is the absence of any Texas state income tax and utility rates that stay close to national norms.

What should you budget monthly to live in Katy, TX?

Beyond your mortgage principal and interest, budget for property taxes at roughly 2.0% to 2.5% of assessed value annually, homeowners insurance, utilities around $195 to $210 per month, any HOA dues, and commuting costs including tolls if you use the Grand Parkway or Westpark daily. The tax and MUD line is the one most often underestimated by buyers relocating from other states.

Why are property taxes different across Katy addresses?

Katy spans Harris, Fort Bend, and Waller counties, so the county portion of your rate changes with your address. On top of that, homes inside Katy city limits carry the city rate while unincorporated addresses with Katy mail service do not, and many master-planned communities add a Municipal Utility District levy. Always verify the actual tax record for the specific property.

How does Katy compare to Richmond, TX on cost?

Richmond, TX runs close to Katy at the median, roughly $366,000 to $381,000 against Katy's $355,000, and both sit within the Greater Houston Area. Richmond is entirely inside Fort Bend County, which simplifies the tax picture compared with Katy's three-county footprint. Katy generally offers more retail and dining density; Richmond often offers more square footage per dollar at the entry level.

Does the lack of state income tax actually offset Katy's property taxes?

For many middle-to-upper income households, yes. Texas collects no state income tax, so income that would be taxed in states like California or New York stays with the household. Whether that fully offsets a 2.0% to 2.5% property tax rate depends on your income level, home value, and the tax structure of the state you are leaving. Run both numbers before you decide.

What geography should you understand before buying in Katy, TX?

Start with the subdivision, then the city, then the county. A Katy subdivision sits inside Katy, TX, which spans Harris, Fort Bend, and Waller counties, within the Greater Houston Area of Texas. That layering determines your tax rate, your utility district, and in some cases whether you are inside city limits at all — three things that directly change your monthly cost.

Are utility costs in Katy, TX predictable year-round?

No. The $195 to $210 monthly average smooths out a wide seasonal swing. Cooling costs during a Greater Houston summer push July and August bills substantially above that average, while mild winter months fall below it. Budget against the summer peak rather than the annual average, particularly in a larger home.
