Because Lusby is an unincorporated community, it does not have its own municipal government or mayor. Instead, it is governed directly by the Calvert County Board of County Commissioners, which oversees public services, zoning, law enforcement, and infrastructure.
At the state level, Lusby is represented in the Maryland General Assembly. Federally, it falls within Maryland's 5th Congressional District. Local public services, including the Calvert County Sheriff's Office and the volunteer fire and rescue squads (such as the Solomons Volunteer Rescue Squad and Fire Department), provide essential services to the community.
