The Grant County Detention Center is located in Williamstown and processes bookings from the Grant County Sheriff's Office, Williamstown Police Department, Dry Ridge Police Department, and other local agencies. Booking records are publicly accessible under the Kentucky Open Records Act (KRS 61.870–61.884). The facility serves a largely rural county that sits at the transition between the Northern Kentucky suburbs and the more agricultural communities of north-central Kentucky.

Williamstown, the county seat, is a small community of roughly 4,000 residents that has experienced a boost in commercial activity since the opening of the Ark Encounter in 2016. The attraction, operated by Answers in Genesis, draws hundreds of thousands of visitors annually and has had a measurable impact on local tourism infrastructure. Dry Ridge, located along I-75 at the junction with U.S. Route 22, is the county's other primary commercial center and serves as a stopping point for travelers along the interstate.

About Grant County

Grant County is a predominantly rural county defined by farming, the I-75 corridor, and the tourism generated by the Ark Encounter. The county's northern edge is beginning to feel the suburban influence of the Northern Kentucky region as development pushes southward along I-75. Crittenden, Corinth, and Jonesville are smaller communities within the county. Grant County's economy historically depended on agriculture and tobacco, but tourism and interstate-adjacent commercial development have become increasingly important. The county's location approximately midway between Cincinnati and Lexington along I-75 gives it strategic value as a stopping point.
