Why is this on my ballot? Arizona's overlapping districts, explained

In one sentence: your ballot is built from a stack of overlapping district maps, and each layer of that stack puts different questions on it.

If your ballot looks long and strangely mixed, with statewide propositions next to a school bond, a city charter question, and judges, that is not a mistake. You do not live in one district. You live in many at once, and each one votes on its own business at the same election.

The layers, from largest to smallest

1. The state of Arizona

Every Arizona voter sees the statewide propositions, such as Prop 141 through Prop 320, and the statewide offices: governor, Corporation Commission, Secretary of State, Attorney General, and the other statewide offices.

2. Your congressional district

The U.S. House district you live in decides which House race you see. In this part of the Valley that is AZ-04 or AZ-05. The line between them runs through neighborhoods, so two houses on the same street can vote in different House races.

3. Your legislative district

The Arizona Legislature is drawn in 30 districts, each electing one senator and two representatives. This site covers LD12, which covers Ahwatukee, west Chandler, southwest Tempe, and part of the Gila River Indian Community.

4. Your county

Maricopa County is its own layer. County measures such as Prop 413, the jail sales tax, and county races such as the Clerk of Court and Community College Board appear on every ballot inside the county, and on no ballot outside it. Countywide judges, including all 57 judges on the retention ballot, are another county layer.

5. Your city or town

City questions appear only inside that city. Chandler voters see the Chandler ballot, Props 430 to 434 and the APS franchise question. Mesa voters see Mesa questions. If you live in one city and work or shop in another, only your home city is on your ballot.

6. Your school district taxing boundary

This is the layer that confuses the most voters, so it gets its own rule: school tax boundaries are not school attendance boundaries. You vote on a school district's bond and tax measures if your home sits inside that district's taxing boundary, whether or not your children attend its schools, and whether or not you live in the city the district is named for. That is why some households in neighboring cities vote on Mesa Unified's Prop 419 bond and Prop 420, and on the Mesa Unified governing board, even though their children attend school elsewhere. You pay the tax, so you vote on it.

7. Your community college district

The Maricopa County Community College District covers the whole county, so its board races, covered on the county races page, appear countywide.

8. Special districts

The smallest layers are special districts drawn for one purpose: a justice precinct, a fire district, a water district, a career and technical education district such as EVIT. The San Marcos justice court and EVIT races appear only inside those districts' boundaries, which is why a voter a few blocks away may not see them at all.

A worked example: Chandler and Mesa Unified

Take a household in west Chandler. Its ballot can include statewide propositions, a U.S. House race, LD12, Maricopa County measures and judges, Chandler city measures, and, if the home sits inside Mesa Unified's taxing boundary, Mesa Unified's bond, property-sale measure, and school board race as well. None of that is an error, and none of it means the household is registered in two cities. It means the taxing maps overlap, and each map gets its own vote.

The practical consequence is worth stating plainly: if a measure on your ballot looks unfamiliar, check the district that put it there before you assume it does not belong to you. It is on your ballot because your address falls inside that district's lines.

How to check your own ballot

Maricopa County's Be Ballot Ready lookup shows the exact ballot for your address, with every district and every question. Use it before Election Day, and bring this site's pages for the questions on it.

How to vote without getting your ballot rejected

  • If you vote by mail, mail your ballot by Tuesday, October 27, 2026. After that, use a drop box or a vote center.
  • Your ballot must be received by 7 p.m. on Election Day, Tuesday, November 3, 2026. Postmarks do not count.
  • Sign and date the affidavit envelope, and write a current phone number so the county can reach you if your signature needs curing.
  • Leaving any item blank is allowed and does not affect the rest of your ballot.
