Hereford has been the county seat of Deaf Smith County since 1898. The County offices, housed in the Deaf Smith County Court House, serve a population of approximately 19,000 county residents. The County Judge presides over a board of four County Commissioners who are elected to rotating four- year terms. The Commissioner’s Court meets every second and fourth Tuesday of the month to dispense county business. Each commissioner presides over a precinct and takes care of that precinct.

The County maintains a Sheriff’s Office consisting of an elected sheriff, Deputies, narcotics officers, a dispatcher, communications center operators, corrections officers, and reserve deputies.

All deputies are certified through the Texas Commission of Law Enforcement Officers Standards and Education. The Sheriff’s Office administers the law to all areas of the county

Hereford has a council-manager form of government. The mayor and six councilmen are elected to rotating two-year terms. The professional City Manager is appointed by the Mayor and City Council (Commissioners). The day-to-day business operations and municipal administration is performed by the City Manager and supporting staff. The City Commissioners meet every first and third Monday of the month. ​

​The City maintains a Police Department with a Chief of Police, a Police Captain, a Patrol Division staffed with patrol officers, a Detective Division, and a Communications Division. All officers are certified through the Texas Commission of Law Enforcement Officers Standards and Education. A general Dispatcher handles incoming calls and dispatches services such as EMS, ambulances, fire department, and police officers.
