Packing Portable Storage: Inventory, Loading and Keep-or-Discard Decisions

Packing a portable storage container is the last step of a sort, not the first. By the time you’re loading, the keep-or-discard decisions should already be made, and everything going into the container should be something you’ve decided to keep. This page covers the packing itself: building an inventory of what’s going in, checking the provider’s restrictions and load limits, packaging and labeling, setting up access, loading by weight and fragility, and recording what ended up where. If you’re still deciding what to keep, step back to schedule sorting before a household move first; packing goes faster when only keepers are left.

Step 1: Inventory Retained Possessions

Start the inventory before you start taping boxes. It serves three purposes: it tells you roughly how much container space you need, it lets you find things later without unloading, and it’s your record if anything is damaged or missing.

• Go room by room and list furniture and large items individually; group small items by box.
• Flag what you’ll need first at the destination or during the storage period (bedding, kitchen basics, tools, seasonal clothing). These load last, near the door.
• Flag valuables and documents that shouldn’t go in the container at all: passports, financial papers, jewelry, medications, irreplaceable photos. Most providers recommend keeping those with you.
• Note anything with special handling: fragile, heavy, must stay upright, temperature-sensitive.

If more than one person decides what’s kept (a family move, an estate), the household decision owner should sign off on the list before packing starts, so nothing is packed that someone else expected to discard, or the reverse.

Step 2: Confirm Provider Restrictions and Load Limits

Portable storage companies publish rules for what can go in their containers and how much weight they can carry. Get the current terms in writing from your provider before you pack, and check:

• Prohibited items. Typically: hazardous materials, flammables and fuels (including gas left in lawn equipment), perishable food, plants, live animals, firearms and ammunition, and anything illegal. Lists differ; use your provider’s.
• Weight limit for the container size you’ve booked, and whether it’s checked at pickup.
• Interior dimensions and door opening, so you know whether the sofa or the armoire fits through.
• Climate and pest protection. Is the container weather-sealed? Will it be stored on your property, at a facility, or in transit? Temperature-sensitive items (electronics, photos, instruments, wood furniture) may need extra protection or another plan.
• Insurance or contents protection, and what it requires of you (for example, an inventory and photos).
• Delivery and pickup dates, and how long you have to load.

Provider loading guides, such as those published by the major portable-storage companies, are the authority for their containers. Where they conflict with general advice, including this page, follow the provider.

Step 3: Prepare Packaging and Labels

Gather supplies before the container arrives:

• Sturdy boxes in a few standard sizes (uniform boxes stack better than mixed).
• Packing tape, a marker, and labels or colored tape.
• Padding: furniture blankets or moving pads, bubble wrap, packing paper.
• Stretch wrap for drawers and doors on furniture, and for upholstered pieces.
• Ratchet straps or tie-downs if the provider allows them, to secure the load to the container’s tie points.
• Plastic bins for anything that shouldn’t sit in cardboard (linens in a damp climate, items stored for months).

Label every box on two sides and the top with a number from your inventory, the room it came from, and a short contents note. Mark fragile boxes clearly and pack them full so they don’t crush when stacked. Disassemble what you can (bed frames, table legs) and bag the hardware, taped to the piece it belongs to.

Step 4: Plan Loading Access

Before delivery, decide exactly where the container goes and confirm it with the provider: level ground or pavement, as close to the door you’ll carry through as the site allows, with clearance overhead and room for the truck to place and later collect it. If the container has to go on the street, check whether your municipality requires a permit. On loading day, clear the path from house to container, prop doors, protect floors and door frames, and stage boxes by the door in the order they’ll load.

If a dumpster is also on site for the items you’re not keeping, the two containers need their own placement and loading plan so nothing crosses over. That’s a separate task: coordinate temporary storage with waste removal before either one is delivered.

Step 5: Distribute Weight per Provider Instructions

A portable container travels on a truck or sits on a lift, and a badly balanced load can shift, damage contents or exceed the provider’s limits. The general order most provider guides describe:

1. Heaviest items first, at the back and along the floor: appliances, dressers, boxed books. Spread them across the width rather than all on one side.
2. Tall furniture upright against the walls, secured with straps where the provider allows.
3. Mid-weight boxes next, stacked in tiers from the back wall forward, heavier boxes below lighter ones.
4. Fragile and light items on top and in protected spaces, never under heavy boxes.
5. Fill gaps with soft items (cushions, bagged linens) so the load can’t shift.
6. Last in, first out: the items you flagged in Step 1 as needed first go in at the door.

Keep a rough running total of heavy items against the weight limit from Step 2, especially if you’re packing books, tools or appliances. The provider’s specific instructions take precedence over this sequence.

Step 6: Record Storage Contents

When the container is loaded and before it’s locked:

• Update the inventory to show which numbered boxes and items made it in.
• Photograph the loaded interior from the door, and photograph valuable items before they’re wrapped.
• Note the container number, the lock you used, where the keys are, and the provider’s contact and reference number.
• Keep a copy of the inventory with you and a second copy somewhere other than the container.

When the container is retrieved or unloaded, check the inventory as items come out, and report any damage to the provider promptly with the photos and inventory as your record.
