Pallet racking in Nazareth, PA.

Nazareth sits on the Route 33 corridor in Northampton County, the north-south spine connecting Route 22 and I-78 up toward I-80, and that corridor has absorbed a substantial share of the Lehigh Valley's newer distribution development. Most of that construction is in Lower Nazareth and Upper Nazareth townships rather than the borough itself — modern Class A buildings running 32-to-40-foot clear with post-tension slabs and ESFR sprinklers — while Nazareth Borough retains older manufacturing and trade-supply stock at 18-to-26-foot. The area's identity is also built on precision manufacturing: C.F. Martin & Co. has built guitars here since the 19th century, and the surrounding cement industry gave Northampton County a heavy-industrial base that still operates. Permitting depends entirely on the parcel — Nazareth Borough, Lower Nazareth Township, and Upper Nazareth Township each administer the Pennsylvania Uniform Construction Code separately, and several use third-party code agencies for commercial plan review.

From Route 33 Class A distribution to precision manufacturing in the borough, permits route through the Nazareth Borough, Lower Nazareth Township or Upper Nazareth Township code office, depending on the parcel with plan reviews typically running three to four weeks. Route 33 Class A buildings are post-tension, so cable mapping and ESFR flue-space coordination come before layout is finalized.
