How the Maryland General Assembly Works

Ninety days a year, 188 lawmakers in Annapolis pass laws and the state budget. A plain guide to the session, the two chambers and how a veto is overridden.

Most of Maryland’s laws begin in a building in Annapolis. The General Assembly is the state legislature, and understanding how it is organized makes the news from each winter and spring much easier to follow.

What is the General Assembly?

The General Assembly is Maryland’s legislature. It has two chambers: the Maryland Senate, with 47 members, and the House of Delegates, with 141. Together that makes 188 lawmakers, and members of both chambers serve four-year terms. The legislature meets in the State House in Annapolis.

How long does the session last?

The General Assembly convenes each year on the second Wednesday in January and meets for a regular session of 90 days. The end of the session is known as sine die, a Latin phrase meaning the legislature adjourns without setting a date to meet again. Because the session is short, the weeks before the final day are typically busy, with a large volume of bills moving between the two chambers.

Where does the budget fit in?

The annual state budget is the legislature’s one non-negotiable job. The General Assembly must pass it before it adjourns, and the governor is required to send a proposed budget to lawmakers early in the session, in the third week of January. Maryland treats the budget differently from other legislation: the budget bill becomes law upon its final passage and cannot be vetoed by the governor.

What happens when the governor vetoes a bill?

For ordinary bills, the governor can sign a bill into law or veto it. The General Assembly can override a veto, but it takes a three-fifths vote of both houses. That threshold means a veto is often decisive unless a bill has broad support across party lines.

A simple way to follow a bill

  1. Introduction. A bill is introduced in the Senate or the House of Delegates.
  2. Committee. Committees hold hearings and decide whether a bill moves on.
  3. Floor votes. Each chamber votes on the bill; a bill must pass both.
  4. The governor. The governor signs or vetoes the bill.
  5. Possible override. The legislature may vote to override a veto with the three-fifths majority.

Why does it matter to ordinary residents?

Decisions made in the 90-day window reach daily life: taxes, schools, health coverage, transport and the rules for local government all run through the legislature or its budget. Because lawmakers are elected, voters have a direct say in who writes those rules. Our guide to Maryland’s 2026 general election dates sets out when voting happens this autumn.

Where to find official information

The legislature publishes bills, hearing schedules and voting records for each session, and the State Board of Elections publishes who is running. For anyone tracking a particular bill, those official records are the best primary source.

This article is a general explainer. Rules about sessions and procedure are set by the Maryland Constitution and the legislature’s own rules, and details can change.
