Sheriff's Office Building 

The Sheriff's Office is located at 1 E. Main Street in Christiansburg, VA. The building previously housed the Montgomery County Courthouse but underwent a complete renovation to meet the needs of the Sheriff's Office and Regional 911 Authority. The last of the Sheriff's Office personnel made the final move from the old Sheriff's Office building into the new facility on September 11, 2015.

The 50,000-square-foot facility houses the Sheriff's Office's deputies and support personnel along with the New River Valley 911 Authority serving Montgomery County, Town of Blacksburg, Town of Christiansburg, and Campus of Virginia Tech.
