Colorado stacks several kinds of government districts on top of one another, and a single home address usually sits inside most of them at once. The main types of districts in Colorado are eight congressional districts, 35 state Senate and 65 state House districts, 23 judicial districts, 178 school districts, and thousands of special districts, all overlaid on 64 counties. Each layer has its own elected officials, its own boundaries, and in many cases its own taxing authority.
Congressional Districts
Colorado has eight congressional districts, each sending one representative to the U.S. House. The state picked up its eighth seat after the 2020 Census, which showed roughly 14.8 percent population growth over the prior decade and a total above 5.7 million residents.1Colorado Independent Redistricting Commissions. Final Approved Congressional Plan Each district now contains approximately 721,714 people.
Boundaries are drawn by the Colorado Independent Congressional Redistricting Commission, a 12-member body voters created through Amendment Y in 2018. Four members are registered with the largest party, four with the second-largest, and four are unaffiliated.2Colorado General Assembly. SCR18-004 Congressional Redistricting The commission cannot draw lines to protect incumbents or favor a party, and is directed to maximize politically competitive districts where possible.3Colorado Independent Redistricting Commissions.

State Legislative Districts
The Colorado General Assembly runs on a separate set of lines. The state Senate is divided into 35 districts and the House of Representatives into 65, with population and county boundaries driving how each one is shaped.4Colorado General Assembly. Colorado General Assembly Overview You elect one state senator and one state representative based on where you live. They vote on the state budget that funds schools, roads, Medicaid, the courts, and most other state-level programs.
These maps are drawn by the Colorado Independent Legislative Redistricting Commission, created through Amendment Z, the companion measure voters approved alongside Amendment Y in 2018.5Colorado General Assembly. SCR18-005 Legislative Redistricting It uses the same nonpartisan structure as the congressional commission. Before 2018, the legislature drew its own maps.
Judicial Districts
Colorado is divided into 23 judicial districts for its trial courts. Article VI, Section 10 of the state constitution authorizes the divisions and requires that each one be made of compact territory bounded by county lines.6Justia Law. Colorado Constitution Article 6 The General Assembly can change boundaries or add districts by a two-thirds vote of each chamber. That is how the 23rd Judicial District came into being in 2020, when Douglas, Elbert, and Lincoln counties were split off from the 18th.7Colorado General Assembly. HB20-1026 Create Twenty-third Judicial District
District courts handle the heaviest trial-level work: felony criminal cases, civil disputes, domestic relations, juvenile matters, and probate. Many of the 23 districts cover several counties, especially in rural parts of the state. Denver is its own district.
Each judicial district also elects a District Attorney, who prosecutes criminal cases within the district’s territory. Office size varies widely, from small rural operations to large urban prosecutorial agencies, because the districts themselves vary so much in population.
School Districts
Colorado has 178 school districts. Each one is run by a locally elected board of education with real autonomy over hiring, curriculum, and budgeting within the limits of state law. School boards can levy property taxes, ask voters to approve bonds, and set mill levy overrides to fund operations beyond what the state’s per-pupil funding formula provides.
School district boundaries rarely match city or county lines. Neighbors across the street from each other sometimes end up assigned to different districts. Districts that receive federal Title I funding take on additional obligations tied to serving low-income students, including students enrolled in private schools within the district’s boundaries.8U.S. Department of Education. Title I, Part A – Improving Basic Programs Operated by Local Educational Agencies
Statewide policy oversight sits with the Colorado State Board of Education. It has nine members: one elected from each of the eight congressional districts, plus one elected at large. The at-large seat exists because the number of congressional districts is even, and both a new district seat and the at-large seat were added after Colorado gained its eighth congressional district.
Special Districts
Special districts are the most numerous and least understood kind of district in Colorado. Organized under Title 32 of the Colorado Revised Statutes, each one is a single-purpose local government created to deliver a service that a county or city either cannot or does not provide. Common examples include fire protection, water and sanitation, parks and recreation, libraries, and ambulance service.9Division of Local Government. Special Districts Colorado has thousands of them, far more than its cities, counties, and school districts combined.
A new special district starts with a petition and a detailed service plan describing the services, proposed boundaries, and estimated costs. The county commissioners or the relevant municipal body hold a public hearing and must approve the plan before the district can proceed. Property owners inside the proposed boundaries get notice at least 20 days before the hearing and can petition to have their land excluded.10Colorado Constitution of 1876. Colorado Revised Statutes Title 32 Special Districts 32-1-204 Once established through an organizational election, the district runs independently with its own elected board of directors, which sets the mill levy and handles day-to-day operations.
Funding comes mostly from property tax assessments and service fees. Under Colorado’s Taxpayer’s Bill of Rights, in Article X, Section 20 of the state constitution, any new tax, tax rate increase, or mill levy above the prior year’s level requires advance voter approval. Multi-year debt obligations face the same requirement unless the district already has cash reserves pledged for repayment.11Colorado Constitution of 1876. Colorado Constitution Art X 20
Metropolitan Districts and Homeowners
One kind of special district deserves separate attention because it affects more Colorado homeowners than any other. Developers of new residential communities commonly create metropolitan districts to finance roads, water systems, parks, and landscaping. The developer typically controls the board during build-out, sometimes for a decade or more, and homebuyers inherit the district’s debt through elevated mill levies on their property tax bills.
Those bills surprise many owners who didn’t fully grasp the obligation at closing. Mill levies in some communities have risen well above the projections given to early buyers. Colorado’s Department of Regulatory Agencies convened a Metropolitan District Homeowners’ Rights Task Force to examine taxing authority, foreclosure practices, communication with homeowners, and governance. If you’re buying in a newer Colorado development, confirming whether a metropolitan district applies to the property, and reviewing its current mill levy and outstanding debt, is one of the most important steps you can take before closing.
Reporting and Oversight
Special districts created after July 1, 2000, must file annual reports with the county commissioners or municipal body that approved them. All special districts must submit annual audit reports to the State Auditor within 30 days of receiving the completed audit, though districts with revenues and expenditures below $1,000,000 can apply for an exemption from the audit requirement.12Division of Local Government.

Counties: The Layer That Ties the Others Together
Colorado has 64 counties. They are political subdivisions of state government responsible for law enforcement, social services, road maintenance, and land-use control in unincorporated areas. Two of them, Denver and Broomfield, operate as consolidated city-and-county governments with the powers of both.
Counties connect the other district types. County treasurers collect property taxes for every overlapping taxing entity, including school and special districts, and keep a statutory collection fee. County commissioners review and approve service plans for new special districts. Judicial district boundaries follow county lines. School districts, while rarely matching any single county’s borders, are administered through the county property tax system.
The practical result: a single property in a growing Front Range suburb might pay taxes to a county, a school district, a fire protection district, a metropolitan district, a water and sanitation district, and a parks district all at the same time. Each has its own elected board, its own budget, and its own mill levy. The line items on a Colorado property tax bill are each a different district at work.
How to Find Your Own Districts
The Colorado Secretary of State’s voter registration lookup lets you confirm your congressional district and your state Senate and House districts by entering your name and date of birth. Your county clerk’s office can tell you which judicial district, school district, and special districts apply to a given address. The fastest way to see every taxing district at once is your property tax statement, which lists each entity that levies against your parcel.
