Business storage: sizing, access, insurance and tax treatment

The monthly figures this page used to open with came off on 7 September 2026, because nothing supported them. What matters more for a business anyway is the part that does not vary by market: what the agreement lets you do in the unit, whether the standard cover is anywhere near your inventory value, and how the rent is treated for tax. Settle the size and the terms here, then get a live quote for that specification.

Sizing by Business Type

The monthly cost column that used to sit in this table came off on 7 September 2026. The figures were hand-typed and unsourced, and the size band is the part that was doing the real work anyway: settle the size and the climate question first, then get a live quote for that specification.

Tax Deductibility

What You Can Deduct

  • Monthly rent for business-only storage units
  • Insurance premiums on business storage
  • Moving costs to and from the storage unit
  • Lock purchases and admin fees
  • Climate control premiums (if business requires it)

How to Document

  • Keep all receipts and monthly statements
  • Maintain a log of what is stored (business vs personal)
  • Take photos of stored business inventory
  • Use a business credit card or bank account for payments
  • If mixed use, document the business-use percentage

A business spending $300/month on storage can deduct $3,600 annually. At a 25% tax rate, that saves $900 in taxes per year. Always consult a tax professional for your specific situation.

Frequently Asked Questions

Can you run a business from a storage unit?+
Almost all facilities prohibit operating a business from a storage unit. This means no customer visits, no office work, no manufacturing, and no living in the unit. Violations can result in immediate lease termination. Some facilities allow brief inventory management visits, but the unit must be used for storage only.
Is business storage tax deductible?+
Yes. Self storage rent is fully tax-deductible as a business expense if the unit is used exclusively for business purposes (inventory, equipment, records). Track all payments and keep receipts. If you use a personal storage unit partly for business, you can only deduct the business-use percentage. Consult a tax professional for your specific situation.
Do you need commercial insurance for business storage?+
Standard facility insurance covers a limited amount (usually $2,000 to $5,000). For business inventory worth more than that, you need a separate commercial storage policy or a rider on your business insurance. Commercial storage insurance costs $30 to $100/month depending on coverage level and the value of stored items.
Can you accept deliveries at a storage facility?+
Most facilities do not accept deliveries on your behalf. Some newer facilities and business-focused storage centres offer package acceptance as a premium service ($25 to $50/month extra). If receiving deliveries is important, ask specifically about this before signing a lease.
What about e-commerce fulfilment from a storage unit?+
While you cannot run a full fulfilment operation from a storage unit, many e-commerce sellers use storage units as overflow inventory space. You pick up inventory periodically and ship from home or a shipping centre. For more serious fulfilment needs, consider a fulfilment warehouse or a business storage facility that allows commercial use.

Still not sure what a unit near you should cost?

Write to us and ask. A person reads every message, and we reply with what we can stand behind, naming the source a figure came from so you can go and check it yourself. We make no promise about how quickly a reply lands. If the question turns out to be one other renters ask too, we may put an anonymised version on the site, and only after you have said you are happy with that.

This site is a price reference. We are not a storage operator or a broker, and rates and availability are set facility by facility and move with how full a building is that week. Confirm the rate, the cover the facility insists on and the notice period you owe with the facility itself before you sign anything.
