Metro District Taxes in Douglas County: What to Check Before You Buy

How much will a metro district add to my property taxes in Douglas County? It depends on the exact address. Metro district levies in Douglas County run from zero to more than 95 mills, so similar homes a few miles apart can carry very different tax bills. Look up the parcel's taxing authorities before you write an offer.

Picture two Douglas County homes at the same price, same square footage, same school district. You'd expect the same tax bill. You might be off by thousands of dollars a year.

Here's an example of what's at stake. Each mill is $1 of tax for every $1,000 of a home's assessed value. On a home with an assessed value of $40,000, used here as an example, Highlands Ranch Metro District's 12.250 mills adds about $490 a year. Sterling Ranch Colorado Metro District 3's 95.522 mills adds about $3,821. That's a gap of about $3,330 a year, or roughly $278 a month, on top of everything else in the payment.

Metro districts are legal, common, and often the reason a newer neighborhood has its parks, trails, and roads. The cost just isn't in the list price. Here's how to find it before you're under contract.

What a metro district is

A metropolitan district is a special taxing district, organized under Title 32 of the Colorado Revised Statutes, that funds public infrastructure such as streets, water and sewer lines, parks, and trails. Developers often use them to pay for that infrastructure up front with bonds. The homeowners inside the district repay those bonds over time through a property tax levy, measured in mills.

Colorado has a lot of them. The Colorado State Auditor's 2024 review, as reported by Colorado Newsline, cited 2,337 active metro districts statewide, according to the Department of Local Affairs.

A metro district levy is separate from an HOA. Some neighborhoods have both: a metro district levy on the tax bill and HOA dues paid to the association.

The Douglas County numbers

Douglas County's certification of levies for budget year 2026 lists every taxing authority in the county and its mill levy. A few metro district examples from that document:

Those mills stack on top of the levies every homeowner in the area pays. The same document shows Douglas County government at 19.774 mills and the Douglas County Re-1 School District at 39.752 mills, before fire, library, water, and other districts.

Many districts in the document levy zero mills. A newer planned community, where the bonds are still being repaid, is where the higher numbers usually show up.

What Colorado law requires sellers to tell you

Every Colorado residential purchase contract carries a bold special taxing district disclosure. Under C.R.S. 38-35.7-101, it tells buyers that these districts may carry debt repaid through property taxes, and that "BUYERS SHOULD INVESTIGATE THE SPECIAL TAXING DISTRICTS IN WHICH THE PROPERTY IS LOCATED."

Disclosure got more specific in 2025. House Bill 25-1219 extended metro district disclosures, which used to cover only new construction, to resale homes in districts organized on or after January 1, 2000. According to an Otten Johnson summary, the law took effect August 6, 2025, and sellers in those districts must give buyers:

• The district's authority to issue debt, levy property taxes, and charge fees
• A property tax estimate stated as a dollar amount
• A copy of the current county assessor's tax certificate

That disclosure is supposed to arrive before or when you sign the contract. If you're touring homes in Douglas County, ask for it early, before you've picked a favorite.

How to look up the taxes on a specific address

You don't have to wait for the seller. The Douglas County Assessor's maps page links to the tools that show it.

Start with the taxing authorities on the parcel

The Assessor's Tax Authorities Lookup shows every taxing authority on a parcel, and the county's "Your Douglas County Taxes" tool breaks down where the property's tax dollars go. If a metro district is on the list, note its name and total mills.

Read the district's own website

Metro districts organized after 2000 are required to post a plain-language explanation of what they do, including the maximum mill levy they can assess to repay debt. Look for the district's authorized debt, its current debt service levy, any operations levy on top, and how many years the debt runs.

Check the fee schedule

Some districts charge fees on top of the levy, for trash service, covenant enforcement, or facilities. A current fee schedule should be available from the district.

Look at last year's tax bill

The seller's most recent property tax bill, or the treasurer's certificate of taxes due, shows the real total for that parcel. Newer homes can be tricky here, because a bill based on a partly built lot can understate what a finished home will owe.

What the number means for your offer

A higher metro district levy doesn't make a home a bad buy. It does change the math.

Your lender will include property taxes in your monthly payment, so a heavier levy can affect how much house you qualify for. It's also part of what the next buyer will weigh when you sell.

Budget for change, too. A district's levy can move from year to year within the limits of its service plan, and the debt term can run for decades. Read the service plan's maximums, because this year's number can change.

Frequently asked questions

Do all Douglas County homes have a metro district tax? No. Many homes sit outside any metro district, and many districts on the county's list levy zero mills. The parcel's taxing authorities on the Douglas County Assessor's lookup tools show whether a specific address is in one.

Is a metro district the same as an HOA? No. A metro district is a government entity that levies property taxes, while an HOA is a private association that collects dues. Some neighborhoods have both.

Can a metro district raise its mill levy? A district can adjust its levy within the limits set by its service plan and voter authorizations. Check the district's website and service plan for its maximum debt service levy and how long that levy can last.
