Ada County Sheriff's Office.

The Ada County Sheriff's Office is the largest local law enforcement agency in Idaho.  The Ada County Sheriff's Office is committed to giving every citizen the best possible service. Our main goal is to ensure Ada County is a safe place to live, work, and play.  We do that by focusing on the causes of crime, encouraging community participation, and making the best possible use of existing resources. Ada County Sheriff’s Office deputies patrol unincorporated Ada County and the cities of Eagle, Kuna and Star. Ada County Sheriff’s employees also manage and staff the 1,224-bed Ada County Jail, run the county-wide 911 emergency dispatch center and fulfill a variety of statutory and cooperative duties. ACSO employees also issue driver's licenses and concealed weapons permits, patrol county waterways, and serve civil process from the courts.
