Understanding the Arizona Legislature

The Arizona legislature is composed of two chambers: the House of Representatives (60 members) and the Senate (30 members). Lawmakers are elected from thirty legislative districts, with each district electing one Senator and two Representatives. All legislators serve two-year terms, and all seats are up for election every two years during the November general election.  The Legislature meets in regular session every year, beginning in January. The current legislative session began in January 2026. 

During the session, lawmakers introduce, debate, and vote on bills that impact workers, unions, and working families across Arizona. The Legislature meets at the State Capitol in Phoenix, and the public can follow bills, committee hearings, and floor votes in real time. You can track legislation, find your lawmakers, and get involved at the official Arizona Legislature website: https//www.azleg.gov

How A Bill Becomes a State Law

1. Bill Introduction - a legislator introduces a bill in either the House or the Senate
2. Committee Hearings - the bill is assigned to one or more committees, where it can be debated, amended, and voted on
3. Floor Vote - if it passes committee, the bill goes to the full chamber (House or Senate) for a vote
4. Second Chamber - if the bill passes, it moves to the other chamber and goes through the same committee and floor vote proceess
5. Final Approval - if both chambers pass the same version of the bill, it is sent to the Governor
6. Governor’s Desk - the Governor can sign the bill into law, veto it, or allow it to become law without a signature
