A special session this, concurrent resolution that. Every couple of weeks, there’s an uproar about an outlandish bill that gets introduced, and halfway through the year, it seems like the state government disappears altogether.

The Arizona State Legislature is a complicated government body that seems to make history and cause controversy more and more with each passing year—yet many Arizonans don’t know what goes on behind the doors of the State Capitol.

It’s not just Arizona: fewer than 20% of Americans can name their state legislators, according to a Johns Hopkins University survey. 

Here’s some information on how the Legislature works, and how to find out who represents you.

How do the two chambers of the Legislature work? 

Arizona’s Legislature is considered part-time, meaning they only meet the first few months of the year. The Arizona Constitution requires the legislative session to begin the second Monday in January, which, this year, is Jan. 12, 2026.

There are a total of 90 legislators in Arizona’s Legislature—made up of 30 Senators in the upper chamber, and 60 Representatives in the lower chamber. 

Arizona has 30 legislative districts, with one senator and two representatives representing each district. Both positions are elected to two-year terms, and legislators can switch between chambers to get around term-limit laws. 

Many senators and representatives are already running for reelection in the 2026 election on Nov. 3.

Legislators are responsible for drafting and introducing bills, voting to pass or reject bills, and debating the merits of bills. The Senate also can create laws and add amendments to the Arizona state constitution, and in conjunction with the House, the Senate approves the state’s annual budget. 

Since the Legislature is only in session for part of the year, either the Legislature, the governor, or both may call special sessions after the Legislature has adjourned for the year for reasons like budget shortfalls or times of disaster (like a pandemic). In special sessions called by the governor, the Legislature may only consider matters specified by the governor. 

Who holds the most power?

The 2026 legislative session will have a Republican majority, with 17 Republicans and 13 Democrats in the Senate, and 33 Republicans and 27 Democrats in the House of Representatives—meaning Arizona’s Republican party holds most of the power. 

Since Republicans secured a majority of members in each chamber, Republicans get to choose who runs committee meetings, which bills to vote on, and what the rules will be. 

Ahead of last year’s legislative session, Republicans elected Rep. Steve Montenegro to be the speaker of the House, and reelected Sen. Warren Petersen to be Senate president. In turn, Montenegro and Petersen set the committee agendas and select legislators to chair those committees. 

Any legislator can write a bill, but only those in these positions get to decide whether or not a bill will be debated and voted on.
