What should you check before choosing a building spot?
Start with the legal limits. Check setbacks from property lines, roads, streams, wetlands, and wells with the county planning office, and ask whether a building permit is required. Rules differ for agricultural buildings in different places, so get the answer for your parcel.
Then look at the ground. Choose a spot that is higher than its surroundings, firm, and well drained, and avoid low areas that collect water or cold air. A pad that looks fine in August may be a pond in April. If the ground is questionable, a local contractor or your conservation district can look at it before you commit to a pad.
How does drainage affect placement?
Water should move away from the building, not toward it. Ground slightly higher than its surroundings, with a clear path for runoff, keeps floors drier and foundations safer. Roof runoff can be large during storms, and where it goes matters as much as where the rain falls.
Manure and animal yards should drain away from wells and streams. The NRCS and your conservation district can help you plan runoff control. Ask for their advice before you build, not after a wet season exposes the problem.
How should access be planned?
Plan for the largest vehicle you expect: a feed truck, a livestock trailer, a hay wagon, or a delivery truck. Make sure it can reach the building in mud and snow and turn around without backing across a yard where children play.
Think about gate widths, door heights, and the surface of the approach. A building that a trailer cannot enter is only half useful. Ask delivery drivers or neighbors what has worked for them. Remember that gravel, culverts, and ditches along the approach also need upkeep, so choose an access you can afford to maintain.
- Width for the biggest vehicle you expect
- A turnaround that avoids backing
- A firm all-weather surface near doors
- Clear sight lines at the road entrance
What about fire and emergency access?
Place buildings far enough apart that a fire in one is less likely to spread to the next. Keep hay, fuel, and the shop away from the house and from animal housing when possible.
Make sure emergency vehicles can reach each building. A clearly marked address at the road, a driveway with enough width and clearance, and a gate that can be opened quickly all help. Your local fire department can advise you on what they need to reach your property.
How do wind, sun, and neighbors influence the choice?
Face openings away from the prevailing winter wind, and use ridges, trees, or other buildings as shelter. Summer breezes can ventilate a barn if the layout allows. South-facing sides can help with winter warmth and with drying wet ground.
Consider odors, noise, and dust for the people next door. Placing barns and animal areas farther from shared boundaries helps keep good relations. A friendly conversation before you build is often worth more than a fence.
How do you future-proof a building site?
Leave room for additions, and run water and electric conduit while the ground is open, if your electrician and local codes allow. Mark where underground lines lie so no one digs into them later.
Take photos of the site before, during, and after construction, and keep copies of permits and plans. If you ever sell, expand, or deal with an insurance claim, those records are valuable.
What are common mistakes with building placement?
Building in a low spot is the most common error, and it is hard to fix once concrete is poured. Another is putting a building too close to a boundary, then learning the setback rule after the walls are up. Check before you build, and keep a copy of what the county told you.
Some owners forget about overhead and underground utilities. A tall building or a loader mast can contact power lines, which is deadly. Call your state's utility locating service before any digging, and stay far from overhead lines when moving equipment.
Others forget to leave a work area in front of the doors. Without room to park, load, and unload, the doorway becomes a muddy mess. Give each door a firm surface and enough space to work safely.
- Never build before checking setbacks.
- Call the utility locating service before digging and watch for overhead lines.
- Give every door a firm, roomy work area.
Key takeaways
- Check setbacks and permit rules with the county first.
- Choose firm, high ground that drains away from the building.
- Plan access for your largest vehicle and for emergency crews.
- Leave room to expand and keep records of the work.
