Here is a scenario I have watched play out more than once. A buyer tours two Castle Pines homes on the same day. Both are listed at $1 million. Both are about the same size. The buyer likes the second one slightly better and assumes the monthly cost is a wash.
It is not a wash. Depending on which community each home sits in, the difference in carrying cost can be several hundred dollars a month, every month, forever. That gap has nothing to do with the house and everything to do with two things nobody puts in the listing photos: the HOA and the metro district.
Almost nobody explains this clearly before you are under contract. So let me.
HOA and metro district are not the same thing
This is the core confusion, and getting it straight makes everything else make sense.
An HOA is a private nonprofit corporation. It collects dues from members. It maintains common areas, amenities, and landscaping, enforces covenants, and funds reserves for future replacement. You pay it directly, usually monthly, quarterly, or annually. If you do not pay, the HOA can place a lien.
A metropolitan district is a unit of local government. It levies property taxes. It was created to finance the infrastructure that made your neighborhood possible in the first place: roads, water and sewer lines, storm drainage, street lighting, parks. You pay it as a line item on your county property tax bill, not as a separate invoice. If you do not pay, it becomes a tax lien.
The practical difference for a buyer: HOA dues show up in your lender's monthly calculation as an obvious number. Metro district taxes hide inside your property tax escrow, where most buyers never break them out. That is exactly why they surprise people.
Many Castle Pines communities have both.
Why metro districts vary so much
Every metro district carries a mill levy, and the mill levy largely reflects how much infrastructure debt the district is still paying off. Newer communities built recently borrowed heavily to install everything from scratch, and they are early in repayment. Older communities have paid theirs down.
The spread within Douglas County is dramatic. For reference, here are reported district mill levies:
- Castle Pines North Metropolitan District: about 3.5 mills as of 2024, down from roughly 19 mills after the district transferred parks and recreation responsibilities to the City of Castle Pines in 2023.
- Canyons Metropolitan District No. 2: about 71.73 mills.
- Highlands Ranch: about 10.1 mills.
- Elsewhere in Douglas County, newer districts run much higher. Founders Village in Castle Rock has been reported near 94.6 mills and Sterling Ranch's district No. 3 near 95.5 mills combined.
Those numbers are not a criticism of newer communities. The Canyons has genuinely exceptional amenities, and someone had to pay to build them. But you should know what you are signing up for.
What that difference actually costs
Colorado's property tax math changed, and most online explanations are out of date. Under HB24B-1001, Douglas County applies two different residential assessment rates for tax years 2024 through 2027:
- 7.05% for school district levies
- 6.8% for local government levies, after subtracting 10% of actual value, capped at the first $700,000
A metro district is a local government levy, so the 6.8% rate applies. Note that the reduction is the lesser of 10% of actual value or $70,000, so a $600,000 home subtracts $60,000 while a $1,000,000 home subtracts the $70,000 cap.
One caveat worth stating plainly: the statute includes a growth trigger. If statewide actual value growth exceeds 5% from 2024 to 2025, the local government rate steps down further rather than holding at 6.8%. Given the softening across the south metro, the 6.8% branch appears to be the operative one, but this is determined by the state, not by inference. The figures here reflect tax year 2026 as published by the Douglas County Assessor at the time of writing.
For a $1,000,000 Castle Pines home, the local government assessed value works out to roughly $63,240. Applying the district levies above:
- In a Canyons metro district (about 71.73 mills): roughly $4,536 per year for that line item
- In Castle Pines North (about 3.5 mills): roughly $221 per year for that line item
That is a difference of about $4,315 a year, or roughly $360 a month, on two homes at the same price.
Now the essential caveat, because this number is easy to misread. Those figures are the metro district line item only. They are not your total property tax bill. Every Castle Pines homeowner also pays Douglas County, Douglas County School District, South Metro Fire, the library district, drainage, and the City of Castle Pines' own levies, which include 4.5 mills for law enforcement passed to the Douglas County Sheriff and 12 mills for parks, recreation, trails, and open space.
A realistic total annual property tax bill on a $1 million Castle Pines home lands somewhere in the $6,000 to $7,000+ range depending on district. The metro district is not the whole bill. It is simply the piece that varies most between one neighborhood and the next, which is why it deserves your attention.
Mill levies are also reset annually and vary by the specific parcel, and district figures published at different times are not always directly comparable. Treat every figure above as illustrative and verify your actual property on the Douglas County Assessor's property search, which lists the exact taxing authorities for that address. I do this for clients before they write an offer, and I am happy to do it for you whether or not we work together.
HOA dues by Castle Pines community
Approximate 2026 ranges. Confirm exact figures with the current HOA disclosure for any specific property.
The Village at Castle Pines: roughly $3,000 to $5,000 per year. Covers gate staffing at five entrances, security patrols, private trail maintenance, parks, and the Canyon Club. Golf memberships at Castle Pines Golf Club and The Country Club at Castle Pines are entirely separate and not included.
The Canyons: a Shea Homes master-planned community with its own structure funding the Canyon House clubhouse, resort-style pool, The Exchange coffee house, more than 15 miles of trails, pickleball, and event lawn. Confirm current dues with the builder or HOA, and note that the metro district levy discussed above is on top of HOA dues, not instead of them.
Castle Pines North / City of Castle Pines: the most variable category, because "Castle Pines North" is many sub-neighborhoods, including Buffalo Ridge, Hidden Pointe, The Retreat, Canterbury Park, Bramble Ridge, Daniel's Ridge, and Whisper Canyon. Dues range from modest to moderate depending on what the association maintains. The upside here is the metro district levy is now very low following the 2023 transfer.
Castle Valley: a newer development with its own association and district structure. As with any newer community, ask specifically about the district's debt position.
The three questions to ask before you write an offer
- What is the total monthly cost of ownership, not just the mortgage? Principal, interest, taxes, insurance, HOA dues, and any separate club or amenity fees.
- What is the metro district's mill levy on this exact parcel, and what is its debt schedule? A district early in a long repayment is a different proposition than one nearly paid off.
- What does the HOA actually maintain, and what is in reserves? An underfunded reserve fund is a future special assessment.
Colorado requires sellers to provide HOA documents. Read them. Specifically read the reserve study and recent meeting minutes, which is where planned assessments show up first.
Frequently asked questions
How much are HOA fees in Castle Pines, CO?
It depends heavily on the community. The Village at Castle Pines runs roughly $3,000 to $5,000 per year. Castle Pines North neighborhoods vary widely by sub-association. The Canyons has its own structure funding an unusually large amenity package.
What is a metro district and why does Castle Pines have them?
A metropolitan district is a local government that issues bonds to build neighborhood infrastructure, then repays that debt through a property tax mill levy. Most newer Colorado communities, including much of Castle Pines, were built this way.
Why are property taxes higher in The Canyons than in Castle Pines North?
Because the Canyons metro district is still repaying the debt that funded its infrastructure and amenities, at a reported levy near 71.73 mills, while Castle Pines North's district dropped to roughly 3.5 mills after transferring parks and recreation to the city in 2023.
Do metro district fees ever go away?
They can decline substantially as bonds are repaid, as Castle Pines North demonstrates. But repayment schedules often run decades, and districts can issue new debt. Ask for the current schedule rather than assuming.
