About Long Island's County Legislatures

Nassau County Legislature

The Nassau County Legislature replaced the Board of Supervisors in 1996 following a federal court ruling that required equal representation. The 19-member body is led by a Presiding Officer elected by the members. The Legislature approves the county budget, passes local laws, confirms appointments, and oversees county departments. Legislators serve four-year terms.

Suffolk County Legislature

The Suffolk County Legislature was established in 1970 when the county transitioned from a Board of Supervisors to a charter form of government. The 18-member body is led by a Presiding Officer. The Legislature shares power with the County Executive in a separation-of-powers system. Legislators serve two-year terms and are responsible for approving the county budget and enacting local legislation.
