Clear a path wide enough for the delivery truck, check for low branches and wires, and move cars and obstacles before the driver arrives. Clearance needs differ by provider, so confirm your measurements when you book. - ## Level and firm A flat, firm surface keeps the container stable. Concrete, asphalt and compacted gravel work. Soft dirt and wet grass do not. - ## Room for the truck The truck needs far more space than the container. Measure the path from the street to the spot. - ## Look up Branches, wires and awnings can block a drop. Two providers cite 13 to 14 feet of overhead clearance. - ## Clear it the day before Move cars, bins and toys. Keep pets and children inside while the truck works. ## What is the best surface for a storage container? The best surface is flat, firm and level. Big Box Storage lists concrete and asphalt as the best fit and compacted gravel as a generally acceptable alternative. These surfaces carry the weight without sinking. Avoid soft dirt, saturated grass and steep slopes. A heavy container can sink or shift on unstable ground. If your yard is uneven, say so when you book. Your provider may suggest another spot. Surface Fit Notes Concrete Best Strong and flat. Protect it if it is new. Asphalt Best Handles the weight well. Ask your provider about new or freshly sealed pavement. Compacted gravel Acceptable Drains well. Needs a firm, level base. Grass Poor Can sink or rut when wet. Soft dirt Poor Can sink or shift. Slope Avoid Steep grades make the unit unstable. You can read more about the ground itself in these terms: [level ground](https://npsa.preview.multisites.ai/glossary/level-ground), compacted base and [gravel pad](https://npsa.preview.multisites.ai/glossary/gravel-pad). ## Does the ground need to be level? Yes, as level as you can manage. A level site makes placement easy and prevents tilting. Big Box Storage says a gentle slope is usually fine, but steep grades or soggy soil can make the container wobble or sink. XCaliber Container says a good site has level, firm ground, no pooling water and few tree roots. Pooling water can damage the container and its contents. Tree roots can cause leveling problems. Look at the ground after a rain. If water stands in the spot, pick another spot or fix the drainage first. ## Can a storage container go on grass? It can, but it is usually a poor choice. Soft turf can sink, rut or hold water under the container. Big Box Storage advises avoiding saturated grass and soft dirt. If grass is your only option, tell your provider. They may place the container somewhere else on your property or advise you on protection. Ask before delivery day. Do not ask the driver to improvise at the curb. ## Do I need a gravel pad or other foundation? A gravel pad is a good fix for soft ground. For a short driveway stay, you usually do not need one. For a longer stay on soft or uneven ground, a foundation helps. XCaliber Container lists three options for shipping containers: 1. **Gravel bed.** It offers stability and drainage. It is ideal on level ground and not suitable for sloped or uneven sites. 2. **Concrete slab.** It suits level surfaces and offers stability. 3. **Railroad ties.** They can help on sites with tree roots by giving a leveling surface. For sloped or bumpy sites, XCaliber says you can combine options, such as a gravel base with a concrete footing. That advice comes from a container seller. Ask your own provider what they accept before you spend money on a pad. If you build a pad, call your local [utility locate](https://npsa.preview.multisites.ai/glossary/utility-locate) service before you dig. Pad work is also a good time to read about site preparation basics. ## How much room does the delivery truck need? The truck needs much more room than the container. Big Box Storage says the driver needs space to approach, maneuver and lower the container into place. Exact numbers differ by provider and container size, so confirm them when you book. XCaliber Container gives these figures for its drivers: - At least 10 feet of width on each side of the container - At least 13 feet of overhead clearance - At least 30 feet of width to turn into a location - At least 10 feet to pull straight through Treat these as one provider’s numbers, not a rule. Delivery systems differ. PODS says its own system needs specific clearances and points to its delivery requirements guide. Some providers use a tilt-bed truck. Others use different equipment. Learn two terms before you call: turning radius and delivery access. ## How do I measure my delivery path? Walk the route the truck will take, from the street to your spot. Measure as you go. Big Box Storage gives a short list you can follow. 1. Measure the length and width of the placement area. 2. Measure the width of your driveway entrance and any gates. 3. Look up along the whole path for power lines and low branches. 4. Check the street for parked cars or tight turns that block the approach. Plan for the container length plus extra room at the front for the truck, says Big Box Storage. Narrow gates, tight driveway entrances and sharp turns are the most common trouble spots. Write the numbers down. Share them with your provider when you book. Photos of the path also help. Ask which container size fits your space. See [what size container you need](https://npsa.preview.multisites.ai/guides/what-size-portable-storage-container) if you are not sure. ## What about overhead wires and tree branches? Overhead clearance is the detail people forget most. Big Box Storage says delivery trucks typically need about 14 feet of vertical clearance. XCaliber Container says 13 feet. That is two providers, two numbers. Look up before delivery day. Branches, power lines and low awnings can block a safe drop. Trim branches ahead of time, and tell your provider about any wires above the spot. PODS also asks that low utility wires be accessible to the driver before arrival. Do not trim limbs near power lines yourself. Call your utility company if branches touch or sit close to a line. See [overhead clearance](https://npsa.preview.multisites.ai/glossary/overhead-clearance) for a plain definition. ## What if my yard is tight, sloped or uneven? Tell your provider before you book. Big Box Storage says to mention an uneven yard when you book so the provider can suggest a better spot. Some providers can place a container in tight spaces, and others cannot, so ask. For a slope, a leveled gravel base or a short run of blocks may help, but only your provider can say what it accepts. Do not build a pad before you ask. If the driveway is too steep or narrow, a storage center may fit better. See [portable storage on site](https://npsa.preview.multisites.ai/portable-storage-on-site) for the on-site option and ask the provider about off-site storage. ## What should I clear before delivery day? Clear the area the day before, or early that morning. The driver can only place the container where there is room. Big Box Storage gives this list. Item What to do Vehicles Move cars, trailers and boats out of the driveway and away from the street in front of it Trash bins and toys Move bins, bikes, planters, toys and hoses out of the area Low branches Trim anything that hangs into the path Pets and children Keep them inside while the truck works Loose debris Sweep away gravel and leaves so they do not scratch the surface Also think about your neighbors. A truck may block a shared driveway for a few minutes. A short note or a quick word helps. ## How do I protect my driveway? Place plywood sheets under the container’s contact points. Big Box Storage says this spreads the weight and helps prevent surface marks or cracks. Sweep first so loose grit does not scratch the surface. Be careful with new or freshly sealed pavement. PODS says newly paved driveways are a no-go. Big Box Storage advises asking your provider before you place a container there at all. If your driveway is new, wait or choose another spot. Tell the driver which direction you want the doors to face. PODS suggests talking to the driver on arrival so the container does not block your garage or sit too far from the door you will use. ## Do I need a permit or HOA approval before delivery? Often you do not need a city permit for a driveway, but you should check. Rules are local. If the container must sit on the street, you may need a right-of-way permit. An HOA may have its own rules even when the city does not. PODS says customers are responsible for securing any municipal permissions. Check before you schedule. Read the full guide: [permits and HOA rules for a container in your driveway](https://npsa.preview.multisites.ai/guides/portable-storage-permits-hoa). Check your state and local rules. ## What should I do on delivery day? Be home if you can, and keep the area clear. Big Box Storage says your presence lets you point out the exact spot and confirm the driver has room to maneuver. If you cannot be there, leave clear written instructions. 1. Walk the driver through the path and the spot. 2. Confirm the door direction. 3. Check that the container sits flat and the doors open fully. 4. Ask how long you have to load, and what extra time costs. 5. Take a photo of the container and the ground before the driver leaves. After the container is placed, PODS advises you not to load while it rains. Wet cardboard can bring moisture inside. To plan the loading, see [portable storage on site](https://npsa.preview.multisites.ai/portable-storage-on-site) and portable storage containers. ## Next step Ready to plan your delivery?

Big Box Storage says a gentle slope is usually fine, but steep grades or soggy soil can make a container wobble or sink. Tell your provider about slopes when you book so the driver can suggest a better spot. Can a storage container sit on grass? Usually it is a poor choice. Big Box Storage advises avoiding soft dirt and saturated grass because a heavy container can sink or shift. Concrete, asphalt or compacted gravel is better. Ask your provider if grass is allowed and what protection they advise. Do I need a gravel pad? Not always. For a short driveway stay, a flat concrete or asphalt surface is enough. For soft or uneven ground, XCaliber Container lists a gravel bed as a stable, well-draining option. It is not suitable for sloped or uneven sites without more work. How much room does the delivery truck need? It varies by provider. XCaliber Container says its drivers need at least 10 feet of width on each side, 13 feet overhead, and 30 feet of width to turn in. Big Box Storage cites about 14 feet of vertical clearance. Confirm your provider's numbers. What about overhead wires and tree branches? Look up before delivery day. Branches, power lines and awnings can block a safe drop. Trim low branches ahead of time, and tell your provider about any wires over the spot so the driver can plan or pick a different place. Should I be home when the container is delivered? It helps. Big Box Storage says you can point out the exact spot and confirm the driver has room. If you cannot be there, leave clear written instructions and keep the whole area open. PODS says you should talk with the driver about door direction. ## Sources 1.
