New construction vs. established homes in Katy: how to choose

In the Katy area right now, new construction and resale prices are closer than they have been in years, which means the decision is less about price and more about trade-offs: a brand-new house in a growing master plan versus an established home with mature trees and a settled school zone. Neither is objectively better. This guide covers where new construction is actually happening, what it costs once MUD taxes and upgrades are counted, and the questions that point to the right choice for your family.

First, a geography note that matters

"Katy" is three different things, and new construction sits in all three. The City of Katy is a small incorporated town, and very little new master-planned building is inside its limits (Cane Island is the notable exception). Greater Katy is unincorporated Fort Bend or Harris County land with a Katy mailing address, which is where most of the big new communities actually sit. Katy ISD is the school district, covering parts of three counties and assigning schools by exact address, so two neighboring communities can feed different schools or even different districts. Tamarron and Jordan Ranch, for example, are marketed as Katy but are zoned to Lamar CISD. Always verify a specific address with the district before you fall in love with a floor plan. The community map labels every community by true geography, and the school zoning guide explains how to check any address.

Where new construction is happening in the Katy area

New-home sales in the Katy orbit are concentrated in a handful of master plans, each with its own geography, school district and price band. This is a mid-2026 snapshot, not a promise: builder lineups, price bands and school boundaries all shift.

• Elyson (77493, greater Katy, Katy ISD): a Newland development with nine active builders, including David Weekley, Brookfield, Perry, Highland, Chesmar and Toll Brothers, which opened its Elyson collections in January 2026 with 340 homes. Prices run roughly from the mid-$300s to about $950,000, with two amenity centers and a 31-acre lake.
• Sunterra (77493, greater Katy and Fulshear edge, Katy ISD and Royal ISD sections): reported as the top-selling master-planned community in Texas with 1,024 sales in 2025. A dozen-plus builders, homes from the high $200s to $800,000-plus, and a Crystal Lagoon amenity.
• Tamarron (77494, Fulshear-adjacent, Lamar CISD): a D.R. Horton-led development with roughly 974 sales in 2025 and about 6,600 homes built by the end of that year. Prices from about $265,000 to $330,000-plus.
• Cane Island (inside Katy city limits, Waller County, Katy ISD): reported as the first major master-planned community inside Katy city limits, north of I-10, with David Weekley, Perry, Westin and Taylor Morrison building there as of September 2026.
• Jordan Ranch (77494, Fulshear, Lamar CISD): David Weekley, Plantation, Westin and Highland build here, and David Weekley's Premier Collection starts around $625,000.
• Firethorne (greater Katy): active new-home listings run roughly $303,000 to $1 million.
• Cross Creek West (Fulshear): the sister community to Cross Creek Ranch, which is no longer selling new homes. Cross Creek West added about 250 homesites in its north tract in 2026, with Coventry and Ravenna Homes joining the builder lineup in June 2026.

The market data page keeps the dated, sourced numbers, and a current search beats any article. For a deeper look at the biggest established plans, the community comparison post lines up Cinco Ranch, Grand Lakes and Cross Creek Ranch side by side.

What new homes cost in 2026

The old rule of thumb was a 15 to 20 percent premium for new construction over resale. By mid-2026 that gap has narrowed to roughly $15,500 in the Katy and Woodlands corridors, according to a June 2026 analysis by Bexley Realty Group. New-construction listings in Katy span about $235,000 to $700,000-plus, with a median listing around $375,000 (Mohebbi Realty Group, 2026), while the resale market sits at a median sale price around $340,000 to $363,000 (Redfin, May 2026). The sticker prices overlap; the real differences show up in the monthly math.

The cost that surprises buyers: MUD taxes

Most Katy-area master plans sit in Municipal Utility Districts, or MUDs, which fund the water, sewer and drainage infrastructure the city does not provide. A MUD tax is billed annually on top of city (where applicable), ISD and county rates. In a new community with active MUD bonds, the total effective rate can run well above the roughly 1.65 percent average effective rate cited for Fort Bend County, and it typically declines over time as bonds are paid off. The practical advice from HAR's 2026 tax guides: ask for the current tax statement and the outstanding bond schedule before you compare two homes, because a lower purchase price can be offset by a higher tax rate, and vice versa.

What you gain with a new home

New construction buys predictability and freshness: a floor plan you choose, a warranty, energy-efficient systems, and no deferred maintenance for years. In 2026 builders are also competing hard for buyers. Incentives such as closing-cost assistance, mortgage rate buydowns and design and upgrade packages are common across Katy-area communities (Nestahead's 2026 builder-incentive guide; LRG Realty's 2026 buydown analysis). And the school picture is genuinely new: Katy ISD opened Robertson Elementary in 2022, Youngblood Elementary in 2023, Nelson Junior High and Freeman High School in 2024, and Boudny Elementary in Elyson and Cross Elementary in Sunterra in 2025, so several new communities now have on-site or nearby campuses rather than long bus rides.

Why an established home can be the smarter buy

Established Katy neighborhoods like Cinco Ranch, Grand Lakes and Seven Meadows trade the showroom shine for things that only age well: mature trees and landscaping, a proven resale history, a settled school zone you can verify against years of attendance data, and a tax statement with a track record instead of a projection. You can often move in within weeks instead of waiting out a build, and the community's amenity program is already finished and funded. For buyers who value location over newness, or who want the largest house for the dollar, resale frequently wins. The Cinco Ranch guide and the Grand Lakes guide show what a mature master plan looks like in practice.

New construction vs. established: a decision checklist

• Verify the school zone by address. Katy ISD, Lamar CISD and Royal ISD all touch the Katy area. Use the district's boundary lookup, not the community's brochure.
• Get the full tax picture. Request the current tax statement and MUD bond schedule for any new home, and the last two years of statements for any resale.
• Price the upgrades, not the base. Compare the final price with the options you actually want, then compare it to resale homes of similar size.
• Time your move. New construction runs on a build schedule measured in months, plus landscaping and fence work. Resale can close in weeks.
• Walk both at the same price. If your budget is $450,000, see what a new build and an established home each deliver before you decide.
• Check the HOA and amenity math. New communities often carry higher HOA dues while amenities are still being built; established communities have a funded track record.
