Sea Cliff incorporated as a village in 1883, with the growing community seeking to gain home rule powers and better control local affairs. The community's public library initially opened in 1894. It formally became a village-administered agency in 1927, through a transfer of charter. In March 2025, Robert Ehrlich, the founder of Pirate's Booty, falsely claimed to be the mayor of Sea Cliff during a "tense standoff at Village Hall", making reference to the Citizen Empowerment Act.
