Pallet Rack Engineering & Permitting

In most Western PA jurisdictions, yes — pallet rack is treated as a structure and typically requires a building permit and stamped drawings once it exceeds a height (often 5'9" to 8' of storage, varying by code adoption) or specified loads, and a fire-code review when it affects sprinkler coverage. We confirm the requirement with your local building department and handle the submittal. Call 724-898-2000 and we will tell you what your jurisdiction needs.

A stamped (sealed) drawing is an engineering drawing reviewed and signed by a licensed Professional Engineer (PE), certifying the rack design meets the applicable building and seismic codes. Building departments require the PE seal before they will issue a permit, and insurers often ask for it too. Langer produces these drawings and provides the seal.

Seismic design is part of the rack engineering required under the IBC and ASCE 7 even in lower-seismic regions like Western PA — the calculations confirm the uprights, base plates, and anchors can resist the code-required lateral forces. Our stamped package includes the seismic calculations your jurisdiction will review.

We prepare and submit the stamped drawing package and manage plan review on your behalf; depending on the jurisdiction the permit is issued to the building owner or contractor of record. We coordinate that with you so nothing stalls. The goal is an approved permit in hand before the crew shows up to install.

Storage height, aisle width, commodity class, and whether you add solid shelves or flue spaces all change the sprinkler requirements under NFPA and the fire code — sometimes requiring in-rack sprinklers. We document storage heights and commodities for the fire marshal and coordinate with your sprinkler contractor so the rack layout and fire protection are approved together.

Drawing preparation is usually a few days to about two weeks depending on system size; plan-review turnaround then depends on the jurisdiction, ranging from days to several weeks. We push the submittal, respond to comments quickly, and keep it moving. Call 724-898-2000 with your timeline and we will map the path for your municipality.
