Storage unit rental checklist
Before renting a storage unit, confirm the interior dimensions and door opening, the access hours, whether insurance is mandatory, what the rate becomes after any introductory period, and the facility's lien and late-fee terms. Photograph the empty unit and your belongings before loading.
- Measure the door, not the unit
- Ask what the rate becomes in month three
- Photograph before loading
Before you visit
- Estimate your volume so you are comparing the same size at every facility — the size calculator takes about two minutes.
- Measure your largest item, including its diagonal depth.
- Check whether your renter or homeowner policy already covers off-site storage.
- Decide whether you need drive-up access or climate control.
At the facility
- Measure the door opening, not the advertised unit size.
- Check the interior ceiling height — 8 ft is standard, 10 ft adds 25% capacity.
- Walk the route from the loading bay to the unit. Corridor turns stop more sofas than door widths.
- Ask about access hours and whether 24-hour access costs extra.
- Look at the floor for water staining and the ceiling for daylight.
- Check the security: gate code, cameras, lighting, and whether staff are on site.
The measurements to take, and the sizes they map to
Take the tape to the unit, not just to your furniture. Advertised sizes are nominal labels, and the opening is always narrower than the space behind it:
| Size | Nominal footprint | Door as advertised | Floor area | Usable volume |
|---|---|---|---|---|
| 5×5 | 5 ft × 5 ft | 4 ft wide roll-up or swing door | 25 sq ft | 170 cu ft |
| 5×10 | 5 ft × 10 ft | 4–5 ft wide roll-up door | 50 sq ft | 340 cu ft |
| 5×15 | 5 ft × 15 ft | 5 ft wide roll-up door | 75 sq ft | 510 cu ft |
| 10×10 | 10 ft × 10 ft | 8 ft wide roll-up door | 100 sq ft | 680 cu ft |
| 10×15 | 10 ft × 15 ft | 8 ft wide roll-up door | 150 sq ft | 1,020 cu ft |
| 10×20 | 10 ft × 20 ft | 8–9 ft wide roll-up door | 200 sq ft | 1,360 cu ft |
Nominal dimensions are not a measurement of the unit you are being shown. Item volumes for the other half of the comparison are in the packed volumes for 95 household items.
Write down the door opening width, the interior ceiling height and the corridor width. Those three decide whether your largest piece arrives, and none of them appear on the price list. For the furniture side of the same comparison, see measuring furniture and door openings.
What the first year actually costs
The advertised monthly rate is the smallest of the questions. Two things move the real number: the fees added at move-in, and the rate you are paying by month twelve.
| Charge | Typical amount | What to ask |
|---|---|---|
| Administration fee | $20–$30, one time | Charged at move-in by most national operators. Occasionally waived if you ask. |
| Lock | $10–$25, one time | Disc locks are usually required. You can bring your own if it meets the spec. |
| Insurance or protection plan | $8–$35 per month | Usually mandatory. Homeowner or renter policies often already cover off-site storage — check before buying theirs. |
| Late fee | $15–$25 plus 10% | Applied quickly, often after five days. |
| Lien or auction fee | $50–$250 | After extended non-payment. Storage liens are enforced faster than most people expect. |
Questions to ask before signing
- What does this unit cost in month three? Introductory rates expire. Get the street rate in writing.
- When was this unit's rate last increased, and by how much? Increases of 8–15% within a year are standard.
- Is insurance mandatory, and will you accept my existing policy? Most will, with a declaration page.
- What is the notice period to move out? Usually 10–30 days, and missing it costs a full month.
- What happens if I pay late? Ask specifically about access suspension and lien timelines.
Full detail on what gets added to the advertised rate is on the storage fees page.
Before you load
- Photograph the empty unit, including any existing damage.
- Photograph and list your belongings — no insurance pays for what you cannot evidence.
- Put down pallets or sheeting. Concrete sweats.
- Buy a disc lock rather than a padlock; shackle padlocks are cut in seconds.
Two things settle most of the list above before you arrive: size it from your own item list so every facility quotes the same load, and the charges added at move-in so the advertised rate does not surprise you at the counter. Once the unit is yours, work out what goes in first covers the loading order.
If the unit is part of a move, the wider timeline matters too — book the unit at least six weeks out, alongside the truck or movers.
Deciding at the counter
Once you have walked the unit, the decision reduces to four checks. Any one of them failing is a reason to look at another unit rather than to negotiate.
- Does the largest item clear the opening? If not, no discount recovers it — choose a wider unit, not a cheaper one.
- Does your volume land in the 60–90% band? Below that you are renting air; above it you are relying on nothing being forgotten. Size up rather than pack tighter.
- Is the twelve-month figure, not the first month, competitive? Compare the number from the table above between facilities. A promotional month is worth less than a $10 difference in the street rate.
- Are the lien, notice and increase terms in writing? A verbal answer about rate increases is not an answer.
Worked example: a two-bedroom load of about 630 cu ft recommends a /storage-unit-sizes/10x10/. At the counter that means checking an 8 ft wide roll-up door against your sofa, confirming $90–$180 is the street rate and not an introductory one, and reading the notice period before signing. If the unit on offer is a /storage-unit-sizes/5x15/ at a better price, the volume works and the 5 ft width does not — that is a decline, not a bargain.
Related questions
What should I check before renting a storage unit?
The door opening width, the interior ceiling height, the route from the loading bay, the access hours, whether insurance is mandatory, and what the rate becomes after any introductory period.
What kind of lock should I use on a storage unit?
A disc lock. Standard shackle padlocks are cut in seconds with bolt croppers, and many facilities now require disc locks by contract.
How much notice do I need to give to move out?
Typically 10 to 30 days depending on the operator. Missing the notice window usually costs a full extra month, so confirm the date in writing when you sign.
