Container Delivery & Placement Requirements: What You Need to Know Before Delivery Day
A practical guide to space, ground conditions, and site prep — so delivery goes smoothly the first time, with no surprises for you or the driver.
What You Need to Know First
Delivery is the part of the process most customers underestimate. Ordering a container or mobile office is the easy part — getting a 30,000+ pound truck and trailer safely onto your site, and getting the unit placed exactly where you need it, depends almost entirely on two things: how much space is available, and what the ground is like when the driver shows up.
Most delivery delays, reschedules, and site damage don't come from equipment problems. They come from tight clearance nobody measured, or ground that turned out to be softer than it looked. This guide covers exactly what to check before delivery day, so nothing catches you off guard.
How Much Space Is Needed to Deliver a Storage Container?
Space requirements depend on the container size and the type of delivery equipment used in your area (typically a tilt-bed or Landoll trailer).
20-Foot Containers
- Straight clearance: approximately 50 to 100 feet, depending on delivery equipment
- Width: approximately 12 feet
- Turning room: the truck needs room to back in and straighten out — tight driveways may require a longer approach
40-Foot Containers
- Straight clearance: approximately 100 to 120 feet
- Width: approximately 12 feet
- Note: 40-foot units need a longer, straighter shot — sites with sharp turns or multiple obstacles may not accommodate a single 40-foot unit without repositioning
Overhead Clearance
- Access route: minimum 13.5 feet of overhead clearance
- At the drop point: 15.5 to 17 feet total, since the trailer lifts the container to set it down
- Trees, power lines, awnings, and low wires all need to be cleared or accounted for before delivery day
Tight-Access or Urban Sites
If your site doesn't have 50+ feet of straight clearance, delivery may still be possible with a smaller truck, a different trailer approach, or repositioning after drop — but this should be flagged when you schedule delivery, not discovered by the driver on-site.
Ground Conditions: What Works and What Doesn't
The delivery truck and trailer can weigh over 30,000 pounds. The surface needs to be level, smooth, and firm enough to support that weight without shifting — otherwise the container can end up unlevel, doors can bind, and the truck itself can get stuck.
Concrete or Asphalt
Ideal in almost every scenario. No prep needed beyond making sure the pad is clear and large enough for the footprint.
Compacted Gravel
A strong option for most jobsites and residential deliveries. If the gravel is loose or thin, add depth and compact it before delivery day.
Dirt
Workable if the ground is dry and firm. Loose, freshly-tilled, or saturated dirt is a problem — see the mud section below. On soft ground, we recommend supporting each corner with gravel, asphalt, concrete footings, pavers, or railroad ties.
Grass
Yes — storage containers can be delivered on grass, as long as the subsoil underneath is firm and well-drained. Grass itself isn't the problem; what's underneath it is. A lawn over compacted, dry soil handles delivery fine. A lawn over soft, saturated, or recently graded soil will rut, and the truck can get stuck.
- Best attempted in dry conditions or dry season
- Confirm the lawn hasn't been watered, irrigated, or rained on heavily in the days before delivery
- Expect some tire tracking on grass — this is cosmetic, not a sign of a failed delivery
- If the site has been consistently wet, plan for a gravel or plywood track-out path instead
Why Mud Matters More Than Any Other Site Condition
Of every ground condition, mud is the one most likely to delay, damage, or outright cancel a delivery. It isn't a minor inconvenience — it's the single biggest reason deliveries go wrong.
- Weight sinks trucks. A loaded delivery truck and trailer can exceed 30,000 pounds. On saturated ground, that weight has nowhere to go — tires sink, and the truck can become stuck before the container is even off the trailer.
- Mud causes ruts and lawn damage. A stuck or straining truck tears up turf and subsoil far more than a clean delivery ever would — the exact damage most customers are trying to avoid.
- It compromises placement accuracy. A trailer that's slipping or unstable can't set a container down level or in the exact spot requested.
- It creates liability and safety risk. A truck stuck in mud, or shifting during unload, is a safety issue for the driver, the site, and anyone nearby.
- It's the most common reason for rescheduling. If your site has seen heavy rain in the 24-48 hours before delivery, mud — not the container size, not the equipment — is the most likely reason a delivery gets pushed back.
The fix is simple: check the ground the day before delivery, not just the day you scheduled it. If there's standing water, visible saturation, or ground that gives underfoot, treat it the same as a hard no until it dries out or is reinforced with gravel or plywood.
Common Container Delivery Mistakes (and How to Avoid Them)
- Underestimating clearance. Measuring the parking spot but not the full approach path — driveways with a turn, a gate, or a narrow gap between structures need more than the container's length.
- Ignoring overhead obstacles. Tree branches, power lines, and satellite dishes are easy to miss when you're only thinking about ground-level space.
- Scheduling delivery right after rain. A site that looks fine on a dry day can turn to mud within hours of a storm — check the forecast, not just the calendar.
- Not marking utility lines. Underground utilities and septic lines should be flagged before a 30,000-pound vehicle drives over them.
- Assuming any flat spot works. Level and firm are two different things — a flat lawn over soft subsoil is still a delivery risk.
- Not communicating door orientation. Deciding which direction the doors should face after the truck arrives, instead of before, often means a second repositioning attempt.
- Skipping the pre-delivery walk-through. A quick call with your rep to confirm space, ground condition, and placement direction prevents nearly every delay on this list.
How to Prepare Your Site Before Delivery Day
A short checklist covers almost everything that affects a smooth delivery:
- Confirm 50-120 feet of straight clearance, depending on container size
- Confirm at least 13.5 feet of overhead clearance along the approach, and 15.5-17 feet at the drop point
- Clear low-hanging branches, wires, and any temporary obstacles (vehicles, equipment, trash bins)
- Check ground conditions the day before — look for standing water, soft spots, or recent rain
- Add gravel, pavers, or plywood track-out if the surface is soft, wet, or recently graded
- Mark known utility lines or septic fields in the delivery path
- Decide and communicate door-facing direction before the truck arrives
- Have someone on-site (or reachable by phone) at the scheduled delivery window
Following this list before delivery day resolves the vast majority of issues before a truck ever leaves the yard.
Ground Conditions Compared
| Ground Type | Delivery Difficulty | Prep Needed | Weather Risk | Best Practice |
|---|---|---|---|---|
| Concrete / Asphalt | Easiest | None | Low | Delivers in almost any weather |
| Compacted Gravel | Easy | Minimal grading | Low-Moderate | Add gravel pad if soft underneath |
| Packed Dirt (dry) | Moderate | Level & compact | Moderate | Check forecast; avoid soft spots |
| Dirt (wet/soft) | Difficult | Gravel or plywood track-out | High | Reschedule after rain if possible |
| Grass | Moderate | Confirm firm subsoil | High | Best in dry season; risk of ruts |
| Mud | Not deliverable | Must be resolved first | Severe | Delivery will be delayed or refused |
Note: conditions vary by region and season. Always confirm current site conditions with your local rep before delivery day.
Common Myths About Container Delivery
MYTH: "Any flat spot works."
FACT: Flat and firm are different things. A level lawn over soft, saturated subsoil is still a delivery risk — firmness matters as much as grade.
MYTH: "Containers can't be delivered on grass."
FACT: Grass delivery is common and usually fine, as long as the ground underneath is firm and dry. It's the subsoil, not the grass itself, that determines whether delivery works.
MYTH: "A little rain the day before won't matter."
FACT: Saturation can persist well after rain stops, especially on clay-heavy or poorly-drained soil. Ground condition should be checked the day before delivery, not assumed from memory.
MYTH: "As long as the parking spot is big enough, delivery will work."
FACT: The full approach path matters as much as the drop point — a wide-enough spot behind a narrow gate or tight turn still isn't deliverable without adjustments.
Frequently Asked Questions
How much space is needed to deliver a storage container?
A 20-foot container needs roughly 50 to 100 feet of straight clearance; a 40-foot container needs roughly 100 to 120 feet. Both require approximately 12 feet of width. Exact clearance depends on the delivery equipment used in your area.
Can storage containers be delivered on grass?
Yes. Grass delivery works as long as the subsoil underneath is firm and well-drained. The grass itself isn't the issue — soft, saturated, or recently graded ground underneath it is.
Why does mud matter so much for container delivery?
Delivery trucks and trailers can weigh over 30,000 pounds. On muddy or saturated ground, that weight can sink tires, stall the delivery, damage the site, and prevent accurate, level placement of the container.
Can a container be delivered right after it rains?
It depends on how the ground drains. Sites with good drainage may be fine within a day; clay-heavy or poorly-drained sites can stay soft for much longer. Check the ground itself, not just the time since the last rain.
What ground surface is best for container delivery?
Concrete or asphalt is ideal. Compacted gravel is a strong second option. Dirt and grass both work if the ground is dry and firm. Mud is the one condition that reliably causes delays or cancellations.
How much overhead clearance is required for delivery?
A minimum of 13.5 feet is required along the approach route. An additional 2 to 3.5 feet (15.5 to 17 feet total) is needed at the actual drop-off point, since the trailer lifts the container into place.
What happens if the ground is too soft on delivery day?
The driver may need to reposition the drop point, add temporary track-out material like gravel or plywood, or reschedule the delivery until the ground firms up. This is far more common — and far less costly — than attempting delivery on unsafe ground.
What are the most common container delivery mistakes?
The most common mistakes are underestimating clearance along the full approach path (not just the parking spot), missing overhead obstacles, scheduling delivery right after rain, and not confirming door orientation before the truck arrives.
The Bottom Line: Space and Ground Condition Decide Delivery Day
- Measure the full path, not just the parking spot. 20-foot containers need 50-100 feet of clearance; 40-foot units need 100-120 feet.
- Overhead clearance is easy to overlook. 13.5 feet along the route, 15.5-17 feet at the drop point.
- Ground firmness matters more than ground type. Concrete, gravel, dirt, and grass can all work — soft or saturated ground is what causes problems.
- Mud is the top cause of delivery delays. Check site conditions the day before, not just the day you scheduled.
- A short pre-delivery checklist prevents almost every common mistake. Clearance, overhead obstacles, ground condition, and door orientation — confirmed in advance.
