How Farms Configure a Hay Storage Building
Same clear-span engineering, different airflow and stacking approach.

Fully Enclosed, Ridge-Vented (30x50)
Full weather protection with ridge and eave venting engineered in to keep air moving over stacked hay — the airflow matters as much as the roof.

Open-Sided Bay (30x50 – 40x60)
One or more sides left open for maximum natural airflow, roof and back wall closed for weather protection — the traditional hay-shed layout, built in steel instead of wood.

Tall Clear-Span Stacking (40x60)
Maximum eave height for stacking hay higher per square foot of floor instead of spreading the pile — the largest hay building Northcraft commonly configures in C-channel.

Combined Hay & Equipment Bay
A dedicated hay section alongside an equipment bay in the same building — common on operations that don't want to build two separate structures.

Frequently Asked Questions
What does a hay storage building cost?
Northcraft's published floors for the hay storage size range start at $18,900 for a 30x50, delivered, scaling up in size through a 40x60, C-channel framing at a 10-foot eave height with standard loads. That covers stamped engineering drawings, the building components, and freight — not doors, windows, insulation, concrete, or erection.
Why does ventilation matter this much for a hay building?
Hay that goes into storage above about 20% moisture can heat internally as it cures, and in rare cases that heat builds enough to ignite — a real, well-documented risk with baled hay, not a Northcraft-specific claim. Good airflow through ridge venting, eave venting, or an open-sided wall design reduces that risk by letting heat and moisture escape instead of building up. Tell us your preferred ventilation approach and we'll engineer the wall and roof configuration around it.
Should the building be fully enclosed or open-sided?
Both are common and the structural frame is the same either way. Fully enclosed protects hay from wind-driven rain and snow at the cost of relying more on engineered venting; open-sided (one or more walls left off, roof and back wall closed) maximizes natural airflow at the cost of some edge-bale weather exposure. Most operations pick based on local climate and how long hay sits before use.
How tall can the building be stacked?
That depends on the eave height you engineer to. Northcraft's published floor assumes a 10-foot eave; going taller lets you stack more hay per square foot of floor instead of spreading the pile wider, and is one of the factors that moves the price above the floor. Tell us your typical stack height and equipment reach and we'll engineer around it.
What loads does the published price assume, and what raises it?
The floors above assume ground snow load up to 35 pounds per square foot and wind speed up to 110 mph. If your county requires more, that moves the price — tell us your zip code and we'll confirm your real number. Eave height above the 10-foot basis and high seismic activity are the other two factors that apply to a building this size.
Do I need a permit for a hay storage building?
Most jurisdictions require a permit, though many carry a separate agricultural-exemption process distinct from standard commercial permitting — check with your county. We provide the stamped engineering drawings your local building or planning department will ask for either way.
Can the building be customized, or is it a fixed set of sizes?
Every Northcraft building is fully customized to your exact specifications — the 30x50-40x60 range isn't a catalog of fixed layouts. Tell us your open-side preference, door placement, and clear height, and we'll engineer to those specs, including a buyer who already has their own plans.
How long does a hay storage building take from order to delivery?
Typically 45-60 days from order to delivery, depending on engineering review and current production volume. Your estimator confirms a real date range once your drawings are finalized.
