If your old home and your new one do not line up, you have three realistic places to keep your belongings: the moving company's warehouse (storage-in-transit), a portable container, or a self-storage unit. Which one fits depends on how long the gap lasts, how far you are moving and who is handling the truck. Self-storage typically runs from about $35 to $160 or more a month depending on unit size, while mover storage is priced on your estimate and governed by federal and state rules you should read before you sign.
This guide walks through each option, what it costs, what to check in the paperwork and how to pack so your furniture comes out the way it went in.
TL;DR
- Storage-in-transit (SIT) means your mover keeps your shipment in its warehouse, generally for 90 days or less, before final delivery. After day 90, mover liability ends and warehouse rules and charges apply.
- Self-storage is the flexible, lower-cost route for a gap of a few weeks to a few months. Monthly rates run roughly $35 to $160+ depending on size.
- If you cannot accept delivery at the agreed time, an interstate mover may put your shipment into storage without notifying you, and you pay the storage, handling and delivery fees.
- Read the bill of lading and inventory before you sign anything. They are your contract and your proof of condition.

Why a gap between homes is so common
Closings slip. A buyer's financing takes longer than expected, a lease ends before the new one starts, or a new build is not ready on the date promised. Retirees who sold a house and are choosing where to settle, families waiting on a school-year move, and business owners relocating ahead of a lease start all run into the same problem: the truck is ready and the home is not.
The answer is to decide, before moving day, where the belongings will sit and who is responsible for them. The worst outcome is the unplanned one. Federal rules allow an interstate mover to place your shipment into storage at your expense if you are not available to accept delivery, so a missed delivery window can cost you money you did not budget for.
Your three storage options compared
| Option | Best for | Typical timeline | Who handles your goods | Main watch-out |
|---|---|---|---|---|
| Mover storage-in-transit (SIT) | Long-distance moves with a short gap | Up to 90 days | The moving company, in its warehouse | Liability ends after day 90 |
| Portable container | Moves where you want to load once and unload later | Weeks to a few months | You load; a carrier transports and stores | Packing and loading are largely on you |
| Self-storage unit | Flexible gaps, local or split moves | Month to month | You, with your own access | You move items in and out yourself |
We cover each below. If you are weighing containers against a traditional crew, our comparison of container moving services versus traditional movers lays out the trade-offs.
Option 1: Storage-in-transit with your mover
The Washington Utilities and Transportation Commission describes storage-in-transit as temporary warehouse storage of belongings for 90 days or less, held while the move to the final destination is pending. The Federal Motor Carrier Safety Administration defines it in similar terms: temporary warehouse storage while a shipment awaits further transportation.
This is the simplest option on a long-distance move because one company has your inventory from pickup to delivery. There is no second truck, no second set of hands and no gap in accountability. For a deeper look at the rules, see our guide to storage in transit for U.S. moves.
The 90-day line
This is the detail people miss. According to the Washington state guide, if your belongings are not removed within 90 days, the move is considered complete and mover liability ends at midnight on day 90. After that, the warehouse's own rules and charges apply. If you expect your gap to run close to three months, ask the mover in writing what happens on day 91, and whether your goods convert to long-term storage under a separate agreement.
When storage happens without you asking
FMCSA explains that when you cannot accept delivery at the agreed time, for example because the home is not ready, the mover may place the shipment in SIT without notifying you. You then owe SIT, warehouse handling and final-delivery fees. FMCSA's FAQ adds that an interstate mover can also store household goods at your expense if you have not paid the charges due at delivery.
Essential Tip: Put your delivery date range in writing, give the dispatcher a phone number that will be answered, and tell the mover as early as possible if the closing moves. A planned SIT booking is almost always cheaper and calmer than an unplanned one.
Option 2: Portable containers
With a portable container, a carrier drops a container at your door, you fill it, and the carrier either transports it to your new address or holds it in a facility until you are ready. The appeal is a single loading session and a built-in storage option. The trade-off is labor: you or hired helpers load and unload, and the quality of that loading determines how your items arrive. Protecting furniture from shifting matters even more when it will sit for weeks.
Containers suit budget-minded movers who are comfortable with the physical work. They are less suited to retirees downsizing from a large home or anyone with heavy antiques, where a crew with wrapping materials is safer.
Option 3: A self-storage unit
Self-storage gives you control. You decide when to visit, what to take out and how long to keep paying. SpareFoot's guide on temporary storage describes it as an affordable, flexible option for gaps between homes.
The cost is mostly your time and effort. You need a way to get the items there and, later, to your new home. On a long-distance move that usually means a mover picks up from the unit or you rent a truck for the final leg. Plan that second step before you sign the rental.
What storage costs
Monthly self-storage averages reported by Today's Homeowner in 2025 break down like this:
| Unit size | Typical monthly cost |
|---|---|
| 5×5 | $35 to $75 |
| 5×10 | $55 to $95 |
| 10×10 | $80 to $100 |
| 10×15 | $90 to $130 |
| 10×20 | $110 to $140 |
| 10×30 | $130 to $160+ |
Rates vary by city, climate control and the facility's promotions, so treat the table as a range, not a quote. Ask about introductory pricing too: a low first-month rate can step up afterward, so compare the full-term cost.
A worked example
Say your closing slips by two months and a two-bedroom apartment's contents fit in a 10×10 unit. At the $80 to $100 range, two months of rent comes to $160 to $200 before insurance, fees or a truck for the second move. Add those and the real figure is meaningfully higher, so ask for every line item. For long-distance mover pricing in general, our interstate moving costs guide explains what drives an estimate.
Mover storage is priced differently: it is tied to your shipment's weight or volume and stated in your estimate and bill of lading. We do not publish flat storage rates, because the figure depends on your shipment, route and the length of stay.
How to choose
Use these criteria in order:
- Length of the gap. Under 90 days on a long-distance move, SIT keeps everything with one accountable company. Longer or uncertain gaps point to self-storage or a separate long-term agreement.
- Distance. The farther you move, the more a single carrier's handoff matters. Splitting the job between a self-storage unit and a second hauler adds a step where things go wrong.
- Your physical capacity. Containers and self-storage mean you load and unload. If that is not realistic, choose a full-service mover.
- Value and fragility of the items. Heirlooms, art and electronics need controlled conditions and careful packing.
- Total cost, not rent alone. Add insurance, access hours, deposits, transport to and from the unit and any late fees.
What to check in the paperwork
FMCSA's Ready to Move brochure explains that the order for service should list pickup and delivery dates, that the bill of lading is your contract and receipt, and that the inventory is the receipt describing each item and its condition. The Washington guide adds that you should check the bill of lading for services, charges and liability.
Before you sign, confirm:
- The pickup date, the delivery date range and what happens if either moves.
- Whether storage is included, optional or charged separately, and the fee structure for warehouse handling and final delivery.
- The 90-day SIT limit and what the warehouse charges after it.
- Who is liable for items while in storage, and at what coverage level.
- Whether items stay on the truck or are unloaded into the warehouse and reloaded, since each handling is another chance for damage.
- Access: can you retrieve a specific box during storage, and at what cost?
FMCSA defines the inventory as a detailed list showing each item's number and condition. Make yours thorough, because it is what you compare against at delivery. Our moving inventory list guide shows the fields to copy, and the mandatory documents for interstate moves page explains estimates and bills of lading in plain language.
FMCSA also runs Protect Your Move, where you can check a mover's registration. It notes that interstate movers must give you the Your Rights and Responsibilities booklet and the Ready to Move brochure before the move.
Red flags with storage offers
- A verbal quote with no written estimate.
- No USDOT registration you can verify.
- Storage fees that appear only at delivery.
- Pressure to pay in full in cash before pickup.
- Reluctance to say where your goods will be stored and who runs the warehouse.
What to pack, and what to leave out
Not everything belongs in storage. The FMCSA notes that if a shipment is partly lost or destroyed by fire after you pack hazardous material such as gasoline, the mover may require you to pay the full transportation cost. Keep flammables, propane, paint and cleaning chemicals out of your boxes, and carry medications, documents, jewelry and anything you need in the first week with you.
Movers and facilities also commonly restrict perishable food and live plants, so confirm the list in writing. Pets are never stored, of course. If you are moving with animals, plan their travel separately from the household goods.
How to protect furniture and boxes in storage
A few weeks is easy on your belongings. Several months is not, especially in humid or hot regions. These steps come from preservation and storage guidance:
- Clean and dry everything first. U-Haul's furniture guidance recommends cleaning and completely drying items, disassembling furniture, and using furniture blankets and mattress bags. It also advises against plastic wrap on upholstered furniture, which can trap moisture.
- Get boxes off the floor. On concrete slab floors, one storage guide suggests lifting boxes at least 4 inches with pallets or wood to prevent moisture wicking.
- Stack smart and leave a path. State Farm recommends heavy boxes below lighter ones, labeled boxes and a center aisle, plus wrapped fragile items and sheets over furniture.
- Mind temperature and humidity. The Texas Historical Commission's 2025 guidance recommends 40% to 60% relative humidity and 59 to 77°F, and avoiding attics and basements. Wood furniture, photographs, instruments and upholstered pieces are the most sensitive, so climate-controlled space is worth asking about for them.
- Check for pests and leaks. The Better Business Bureau advises choosing a facility with good security and monitoring, looking for signs of neglect such as pests or leaky roofs, and considering insurance.
Fragile and sentimental items
Heirlooms, glassware and framed pieces need more than a wrapped box. This guide to packing fragile heirlooms with extra cushioning covers double-boxing and photo documentation, which also helps if you ever file a claim. Our own tests on cushioning are in how to pack fragile items, and our heirloom antiques and glassware transport guide covers the highest-value pieces.
Insurance
Check your own policy. One storage guide reports that renters or homeowners policies often extend to off-site storage at roughly 10% of the contents limit, though many exclude risks like mold or vermin. Call your insurer and ask, then compare that with the valuation coverage the mover or facility offers. Our article on what movers do with furniture wrapping and the $0.60 per pound trap explains why default liability can leave you underprotected.
Our perspective
We see the same pattern every season: people book a mover, then discover the gap in their housing timeline, and they scramble. We recommend deciding on storage during your first quote, not the week of pickup. Tell every mover you speak to that your delivery date may move, and ask each to put their storage terms, the 90-day limit and the fee categories into the written estimate.
Our network is made up of pre-screened, licensed and insured movers, and our coordinators act as your single point of contact, so changes to a delivery window go through one person instead of being passed between a dispatcher, a driver and a warehouse. We work with binding estimates so the figures you see are the figures you plan around. If your closing date is uncertain, say so at the start: it changes which mover and which storage option we point you toward.
Our honest advice on the choice: for a long-distance move with a gap under three months, keep everything in one chain of custody with SIT. For anything longer, or if you want frequent access, use a self-storage unit and plan the second leg in advance.

FAQ
How much does it cost to store furniture between moves?
Self-storage units cost roughly $35 to $75 a month for a 5×5 up to $130 to $160 or more for a 10×30, according to 2025 averages. A 10×10 unit, enough for a small apartment, runs about $80 to $100. Add insurance, deposits and the cost of moving items in and out.
How long can a mover store my belongings?
Storage-in-transit is meant for 90 days or less. After day 90, the Washington state guide says mover liability ends and the warehouse's rules and charges apply. If you need longer, ask for a separate storage agreement in writing.
Can a mover put my things in storage if I am not ready?
Yes. If you cannot accept delivery at the agreed time, an interstate mover may place your shipment in storage without notifying you. You are then responsible for the storage, warehouse handling and final-delivery charges.
What are red flags when hiring movers who offer storage?
Watch for quotes with no written estimate, no verifiable USDOT registration, fees that surface only at delivery and vague answers about where your goods will be kept. You can verify a mover's registration on FMCSA's Protect Your Move site.
