Arapahoe County Detention Facility

The detention facility has come a long way since the doors to the one-room jail house in Littleton opened in 1865. After many years in operation, a new structure was built nearby that accommodated the sheriff's office and a much larger jail. In 1987, a 299,241 square foot detention facility opened at 7375 South Potomac Street, in what is now the Centennial, with a bed space capacity of 404. In 1999, construction began on two additional housing units, followed by occupancy in late 2001 and early 2002. With expansion and remodeling, the facility now accommodates approximately 1,400 inmates, currently receives an average of 17,000 inmates annually and is staffed around the clock by civilian personnel, medical personnel, non-certified deputies and Colorado POST certified deputies.
