The Arizona legislature: how it works

What your state legislature controls covers the general powers. This page profiles Arizona's legislature.

The basics

The Arizona Legislature is bicameral: a 60-member House of Representatives and a 30-member Senate, drawn from 30 legislative districts that each elect one senator and two representatives. Both chambers serve concurrent 2-year terms, and members face a consecutive term limit of four terms (8 years) per chamber before a mandatory break of at least one full term. The National Conference of State Legislatures classifies Arizona as a hybrid legislature: lawmakers report spending roughly three-quarters of a full-time job on legislative duties, and most still hold outside income. Regular sessions convene the second Monday in January under the state constitution and typically run several months, with adjournment timing varying by year rather than a fixed statutory end date. The 57th Legislature's 2026 second regular session convened January 12.

Who controls it now

Republicans hold majorities in both chambers: 17-13 in the Senate and 33-27 in the House. All 90 legislative seats are up for election November 3, 2026.
