Other executive departments maintain police departments. The Maryland Capitol Police of the Department of General Services provides security at State buildings in Annapolis and Baltimore, and may enforce laws and make arrests within 1,000 feet of those buildings and grounds. The Natural Resources Police Force of the Department of Natural Resources is the State's oldest law enforcement agency, with statewide jurisdiction to enforce conservation, boating and criminal laws. Moreover, the Department of Transportation supervises two police forces, the Maryland Transit Administration Police, and the Maryland Transportation Authority Police.
Not all Maryland counties have local police departments. In those that do, the police department is the county law enforcement agency. In others, local departments of public safety may oversee responsibilities for animal control, corrections (detention centers), emergency services, fire, and police.

With a county or municipality, the Department of State Police may enter into an agreement to provide some or all local police functions. In counties without a local police department, the Sheriff serves to enforce the laws.
