Two similar Ouray County homes can have different tax bills
A Colorado property tax bill comes from actual value, an assessment rate, and the mill levies of every district covering a parcel, so two like homes in Ouray County can owe different amounts.

If you compare two similar-looking homes in Ouray County and find their property tax bills are different, that is not a mistake. Colorado builds the bill from a few moving parts, and the parts can differ block to block.
It works in three steps. First the county assessor estimates the property’s actual value. Then the state applies an assessment rate to turn that into an assessed value. Finally, the mill levies of every taxing district that covers the parcel are added up and applied to that assessed value. Those districts can include the county, a town, a school district, and special districts for things like fire protection or water and sanitation.
That last layer is where two nearby homes can split. One parcel might sit inside a special district that the one next door is just outside of, so it carries an extra mill levy the neighbor does not. Same county, different total.
Two offices handle the pieces locally. The assessor sets the value; the treasurer sends and collects the bill. Rates and levies change year to year, so it is not worth memorizing a number. What is worth doing before you buy is asking which districts cover a specific parcel and what the current levies are. The Colorado Division of Property Taxation explains how the system fits together, and the county assessor has the parcel-level details.
