Ask a longtime Highlands homeowner how they used to explain the neighborhood's public improvement district to a curious buyer, and most describe the same habit: pull up the water bill. For nearly a decade, that was the fastest way to size up what a Highlands property actually cost to carry, because for homeowners billed separately, the annual assessment that funded the district's share of fire service showed up as a monthly surcharge right there next to the usage charge, plain and itemized.
That habit stopped working last fall.
Trophy Club Municipal Utility District No. 1 expanded its service boundaries to match the area it actually serves, which now covers all of Trophy Club, including the Highlands PID, and a portion of Westlake. Before the expansion, homeowners inside the PID paid for fire protection two different ways depending on which side of the district line they sat on: some paid through the MUD's property tax, others paid through a standalone PID emergency services assessment billed on the water statement. As of October 1, 2025, that split ended. Every resident now pays for fire service through the same mechanism, the MUD's ad valorem property tax, collected alongside the rest of the annual tax bill rather than itemized on a utility statement.
The Town of Trophy Club's own materials are direct about the mechanics: residents pay one or the other, never both, and the change first showed up on 2025 tax year bills due by January 31, 2026. For homes valued above the PID's average, the shift meant a slightly higher annual amount. For homes valued below average, it meant a slightly lower one, because the old PID assessment was a flat per-lot figure and the new one scales with the home's appraised value, the same as any other property tax line.
Here's the part that gets lost when people hear "the PID surcharge went away." Only one of the Highlands PID's two assessments moved into the MUD tax, according to the Town of Trophy Club. The other is still exactly where it's always been.
The Highlands at Trophy Club was created in 2007 as a planned development; FinanceDTA describes it as 697 acres with roughly 1,474 units, while the Town of Trophy Club says the PID itself covers about 609 of those acres and an estimated 1,409 residential lots. To build the streets, drainage and utilities for that footprint, the district issued $27.5 million in special assessment revenue bonds that same year. That fixed infrastructure assessment, the one tied to lot size rather than home value, was never part of the boundary expansion. It's still a separate line, still payable in a lump sum at any time through the district's assessment administrator, as the Town of Trophy Club explains, and still on track to keep collecting for as long as those 2007 bonds remain outstanding, which for a district-financed bond of this type typically runs somewhere in the range of twenty to forty years from issuance.
Put plainly: the water-bill fire-service assessment moved into the MUD tax, while the separate bond-repayment assessment remains on its own line, collected through Denton County.
| Before October 1, 2025 | After October 1, 2025 | |
|---|---|---|
| Fire service assessment | Some paid through the MUD's property tax; others through a flat per-lot surcharge on the water bill | Ad valorem tax scaled to appraised value |
| Fixed infrastructure assessment | Separate line, tied to lot size | Unchanged, still separate, still tied to lot size |
| Where to verify | MUD property tax statement or water/utility statement | County property tax statement |
This matters more than it might sound, because the two assessments now respond to completely different inputs. The infrastructure assessment is fixed to the lot itself, so it's identical whether the house on that lot is a modest single story or a recent rebuild with a full renovation. The fire service portion is now tied to appraised value, so a home that's been significantly updated or expanded will carry a noticeably higher share of that cost than a comparable lot with an unrenovated house, even if the two homes sit across the street from each other.
That's a real pricing variable, not a rounding error, and it's the kind of thing a quick Zillow-style estimate has no way of capturing because it depends on which parcel you're standing on and what the county has that parcel appraised at this year.
The timing makes this worth paying attention to right now specifically. Freddie Mac's survey put the average 30-year fixed mortgage rate at 6.66 percent as of the end of July 2026, and Dallas-Fort Worth nonfarm employment was still up 1.3 percent year over year as of June 2026 according to federal labor data. Financing remains expensive enough that buyers are running tighter monthly budgets than they were two or three years ago, and a few hundred dollars a year in assessment differences between two Highlands lots is exactly the kind of detail that shows up in a debt-to-income calculation before it shows up in a listing photo.
Texas law hasn't relaxed on any of this. Property Code Section 5.014(A) still requires a specific written notice to buyers before they sign a contract on a home inside a PID, and Trophy Club maintains its own template of that notice for exactly this development.
Since the fire service portion moved off the water bill, checking the two assessment amounts now means looking in two different places rather than one: the county tax record for the fire service share, and the PID's own assessment roll for the fixed infrastructure share.
A few things worth confirming before either side signs anything:
For sellers, the practical shift is about pricing consistency. Comparing your home to a similar Highlands sale from two years ago without adjusting for this billing change risks pricing against a cost structure that no longer exists. For buyers, the shift means the old shortcut of glancing at a seller's utility bill to spot-check the assessment no longer tells the whole story.
None of this makes the Highlands a less desirable place to buy. It makes it a neighborhood where the fine print moved.
Does every home in Trophy Club sit inside this PID? No. The PID covers the Highlands development specifically, roughly 609 of its 697 acres. Homes elsewhere in Trophy Club are not subject to these assessments.
Is the fixed infrastructure assessment the same for every lot? No. It's allocated based on lot size, so larger parcels carry a larger share of the original bond repayment than smaller ones.
Can the fixed infrastructure assessment be paid in full? The fixed infrastructure assessment can be paid in full at any time through the district's assessment administrator.
Is a PID the same thing as a MUD? No, and the distinction matters here specifically. A MUD can levy taxes, while a PID uses assessments to repay bonds, as the Town of Trophy Club explains. The Highlands has both, which is exactly why last fall's change only touched one of them.
If you're evaluating a purchase or a sale inside the Highlands, or anywhere else in Trophy Club, Southlake, Westlake or the surrounding DFW communities, the fine print is exactly the kind of thing worth walking through before you write or accept an offer.
