The Annex facility, like all  Mecklenburg County Jails is a direct supervision facility. It was established as emergency housing for minimum and low medium inmates of Mecklenburg County.  Jail Annex was built to relieve the overcrowding of Jail Central and Jail North. This project was completed in less than a year  and opened to Administrative Staff in January 2009.  Some unique features implemented inside the construction are video visitation and Retherrm ovens.  These state of the art systems allow for a more controlled environment while reducing the labor intensity a detention facility requires.   The holding capacity is 640 male inmates, housing 40 inmates per dormitory.   Outdoor recreation yards complete the outside structure giving inmates a safe and healthy way to promote exercise.

ABOUT THE BUILDING STRUCTURE

Sprung structure was an idea that derived from a correctional facility in Lee County, Florida.  The Sprung structure consists of an aluminum frame, insulated cross section and a Tedlar exterior protective film coated architectural membrane.  Tedlar exterior protective film guards against UV and airborne contaminants and dramatically extends membrane life.  The structure has been developed to withstand wind, fire, snow, and just about any menace that nature can deliver.  The walls are constructed with 2 layers of 5/8’ high impact dry wall, reinforced with steel rebars and concrete.  When inside it's hard to visualize the outside structure. 

There are three buildings that make up the Annex:
Administrative Building - 10,536 square feet
Housing Unit A - 36,369 square feet,   460x120'
Housing Unit B - 36,369    460x120'
Apex height - 31 feet
