Pallet racking in Chambersburg, PA.

Chambersburg anchors the southern end of Pennsylvania's I-81 distribution corridor, close enough to the Maryland line to serve the Baltimore–Washington market and far enough up the interstate to reach New York in a day. The Exit 14–20 stretch through Guilford and Antrim Townships holds a dense cluster of Class A distribution centers — 32-to-40-foot clear on post-tension slabs — serving big-box retail, grocery, and third-party logistics networks. Letterkenny Army Depot adds a substantial defense contractor and government-supply base with its own documentation and controlled-access requirements. Food processing and agricultural supply round out the market. Older borough manufacturing and agricultural-processing buildings run 18-to-26-foot clear. The Borough of Chambersburg Land Use and Community Development reviews permits inside the borough; township code offices or the PA Department of Labor & Industry handle the surrounding industrial parks.

From Letterkenny Army Depot contractors to the I-81 Exit 14–20 distribution cluster, permits route through the Borough of Chambersburg Land Use and Community Development (township code office or PA L&I outside the borough) with plan reviews typically running two to four weeks. Letterkenny Army Depot contractor work often carries added documentation and controlled-access scheduling requirements.
