Pull up two different sources for the Highlands Ranch Metro District's current mill levy and you'll get two different numbers. One shows 10.110 mills, tied to a 2024 board decision covered by Colorado Community Media. Another, pulling from the state's Division of Property Taxation registry, lists 12.250 mills for the following tax year. Neither is wrong. The rate moved. That's the first thing worth knowing about the line on your tax bill that most buyers skip past on their way to the HOA fee: it isn't fixed, it's recertified every December, and the number you find in a blog post from six months ago may already be out of date.
That volatility is also the reason this line deserves more attention than it gets. Most guides to Highlands Ranch stop at defining the difference between HOA dues and metro district taxes. That's useful but incomplete. The more useful question for anyone comparing South Denver suburbs right now is why Highlands Ranch's number stays low relative to what newer Douglas County developments are charging for the same basic thing, and what that gap tells you about a community's financial posture ten years out.
Two separate charges, one tax bill
Highlands Ranch homeowners typically encounter two distinct costs that get conflated constantly. The Highlands Ranch Community Association, known as HRCA, is a private nonprofit that collects a quarterly assessment to run the four recreation centers, maintain trails and parks, and operate the 8,200-acre Backcountry Wilderness Area. According to HRCA's own 2026 proposed budget, the total quarterly homeowner assessment is set at $174, an increase of $12, or 1.75 percent, over the prior year.
The Highlands Ranch Metro District is a different animal entirely. It's a unit of local government with an elected board and actual taxing power, and because Highlands Ranch is unincorporated, with no city council or mayor, this district functions as the closest thing residents have to city hall. Its mill levy shows up on the Douglas County property tax bill, not as a separate invoice, which is exactly why it gets overlooked. You can find the district's budget and mill levy documents through its own financial transparency page, and the actual number for any specific parcel comes from Douglas County, not from any blog, including this one.
Why the number stayed small for so long
Highlands Ranch was founded in 1981 on a 22,000-acre cattle ranch, developed initially by the Mission Viejo Company, and it grew large enough to house roughly 100,000 residents before most of today's metro district playbook existed. That timing matters. The district's board has kept its levy well under the 12.750 mills voters authorized as a maximum, and the community transitioned to resident-controlled boards relatively early compared to newer master-planned developments, where developer-appointed boards often stay in place for years while infrastructure debt accumulates.
In 2024, the district's board actually lowered the levy to 10.110 mills, a 9.7 percent cut from the year before, even as home values were climbing. A district spokesperson described the decision this way to the Highlands Ranch Herald at the time, noting that the number the board certified was lower than what state tax law would have otherwise allowed. The following year's certified rate climbed back up to 12.250 mills, still under the voter-approved ceiling but a reminder that the district's restraint is a choice made annually, not a permanent feature of the address.
The water utility tells a similar story. The Centennial Water and Sanitation District, recently renamed Highlands Ranch Water & Sanitation, built real surface water and reuse infrastructure rather than leaning entirely on the depleting Denver Basin aquifers that several other Front Range communities still depend on. Both decisions point the same direction: a community that paid for durable infrastructure early and kept its ongoing tax ask modest as a result.
What the alternative looks like, twenty minutes down I-25
The clearest way to see what that discipline is worth is to look at what happens when it's absent, and Douglas County has two working examples close enough to compare directly.
Founders Village, a Castle Rock community governed by the Founders Village Metropolitan District and the Villages at Castle Rock Metropolitan District No. 4, carries a 2024 mill levy of 94.56 mills, the highest single metro district rate in the county and roughly nine times what Highlands Ranch residents pay. That figure traces back to a 1991 Chapter 9 bankruptcy plan that restructured the original 1986 bonds into a 40-year obligation. The district's own public communications indicate the debt is on track to be discharged in 2031, after which the levy is expected to drop meaningfully. Until then, on a $700,000 home, that one line on the tax bill runs about $4,440 a year, and once county, school, and other authorities are added in, the combined mill levy for the area clears 164 mills.
Dawson Trails, a roughly 2,000-acre development on the south end of Castle Rock anchored by an incoming Costco and a new interchange at Crystal Valley Parkway and I-25, shows the same pattern happening in real time rather than as history. The Town of Castle Rock approved an amended service plan for the project on September 6, 2022, authorizing the Dawson Trails Metro Districts Nos. 1 through 7 to carry a combined $1,062,390,000 in debt, call it a billion dollars, across seven districts that currently share a single mill levy of 74.044 mills, about seven times the Highlands Ranch rate. That debt load is financing infrastructure for 5,850 approved homes and 3.2 million square feet of commercial space that doesn't fully exist yet.
| Community | Governing district | Current mill levy | Roughly how it started |
|---|---|---|---|
| Highlands Ranch | Highlands Ranch Metro District | 10.110–12.250 mills (capped at 12.750) | Built out gradually from 1981, limited bond leverage |
| Founders Village (Castle Rock) | Founders Village Metro District / Villages at Castle Rock Metro District No. 4 | 94.56 mills | 1986 bonds restructured under 1991 bankruptcy |
| Dawson Trails (Castle Rock) | Dawson Trails Metro Districts Nos. 1–7 | 74.044 mills | $1.06 billion authorized in 2022 to build infrastructure ahead of homes |
None of this means Founders Village or Dawson Trails are bad places to buy. Both are financing real infrastructure, and in Dawson Trails' case, a lot of it is arriving alongside genuinely useful additions like the new interstate interchange. But a buyer comparing a Highlands Ranch resale to new construction in either of those Castle Rock developments is comparing two very different financing philosophies, and the mill levy is the one line on the paperwork that tells you which one you're looking at.
What this actually means if you're comparing homes right now
If you're weighing a resale in Highlands Ranch against new construction elsewhere in Douglas County, the metro district line deserves the same scrutiny as square footage or lot size. A few things are worth confirming before you write an offer, on any property:
- Ask what mill levy is currently certified for that specific parcel, not the figure from a listing description or an older blog post. Douglas County recertifies these annually every December, and the rate can move both directions.
- Ask whether the district's debt has a known payoff date. Founders Village's own communications point to 2031. A newer district like Dawson Trails is still early in a 40-year-style obligation, which means today's rate is closer to the start of the curve than the end of it.
- In Highlands Ranch specifically, confirm whether the property also sits inside a neighborhood sub-association, since HRCA's quarterly assessment and a sub-HOA's separate dues are billed differently and two homes a short walk apart can carry different total costs.
- Request the resale certificate. Colorado's Common Interest Ownership Act requires one for homes in common interest communities, and it will list current assessments and any special assessments the seller already knows about.
FAQ
Is the metro district charge the same as my HOA dues? No. HRCA is a private association that bills a quarterly assessment for recreation centers, parks, and trails. The Highlands Ranch Metro District is a unit of local government that levies a mill rate collected with your county property taxes. A single home can be subject to both.
Will the Highlands Ranch mill levy definitely stay under 12.750? That's the voter-authorized ceiling as things stand today, and the district's board has generally certified rates below it. But the certified number moves year to year, most recently from 10.110 to 12.250 mills, so it's worth checking against the current tax year rather than assuming last year's figure still applies.
Does a lower mill levy always mean fewer amenities? Not necessarily. Highlands Ranch's relatively low metro district rate coexists with four recreation centers, dozens of parks, and an 8,200-acre wilderness area, funded mostly through the separate HRCA assessment rather than the tax bill. The mill levy mainly reflects how much infrastructure debt a district is still carrying, not how much a community offers its residents.
