For a Hong Kong small business — an online shop, a trader with samples, a service firm with archive boxes, a workshop with spare equipment — mini storage is usually the cheapest way to get real stock space without a multi-year warehouse lease. But the "cheaper than a warehouse" line needs actual numbers, because the two options price space very differently. The honest version: warehouse and industrial space runs roughly HK$9–18 per sq. ft. per month in Kwai Tsing, Kwun Tong and the New Territories (recent market reports), while an urban mini-storage unit works out to about HK$60–130 per sq. ft. Mini storage is up to five to ten times more expensive per square foot — yet it is still the lower bill for most SMEs, because you rent 8–42 sq. ft. instead of a unit of a few hundred square feet you don't fully need.
| Warehouse / industrial unit | Mini-storage unit |
|---|---|
| ~HK$9–18 per sq. ft. per month (Kwai Tsing, Kwun Tong, Yuen Long, Tuen Mun) | ~HK$60–130 per sq. ft. per month in urban branches; roughly HK$60–80 on first-month offers |
| Taken in hundreds of square feet; small units are rare and still carry lease paperwork | Units from 8 sq. ft. up; scale in single-digit steps |
| Typically 2–3 years, plus a deposit (often 2 months) and agency fee | Month-to-month; most chains from 1 month minimum, some offer 14 days' notice to end |
| Rates, management fees and fit-out usually on top of rent | Rent plus a lock/card fee and a refundable deposit; no fit-out |
| Mostly New Territories — RVD records 88% of private storage stock there (Kwai Tsing, Sha Tin, Tsuen Wan) | Urban branches across Hong Kong Island, Kowloon and the New Territories |
Now a real published example. Spacebox's Sai Wan branch (Cheung Fat Industrial Building, one minute from HKU station) lists an 8 sq. ft. unit at HK$1,058 a month and a 42 sq. ft. unit at HK$4,106 — roughly HK$98–132 per sq. ft., with introductory offers bringing the same units to HK$648 and HK$2,498 (about HK$60–81 per sq. ft.). Apple Storage's Chai Wan branches start around HK$478–630 a month. For stock that fits in a unit, that is a fraction of a warehouse bill. The maths only flips once you need a few hundred square feet — at that point a warehouse unit, or a third-party fulfilment warehouse charging roughly HK$200–350 per pallet a month, usually wins on cost. See our costs and fees guide for how to compare the all-in price.
Common business use cases
- E-commerce stock. Cartons waiting to be picked, packed and shipped. Frequent access and a packing-friendly environment matter — many sellers keep a dedicated shelf for bubble wrap, tape and shipping boxes.
- Documents and archives. Accounting records, client files and signed contracts that the law or your auditor requires you to keep for years. In Hong Kong, the Inland Revenue Ordinance (Cap. 112) s.51C and the Companies Ordinance (Cap. 622) both require business records to be kept for at least seven years — the classic archive use case.
- Trade samples and marketing materials. Brochures, display units, trade-show booths and product samples you take to client meetings and exhibitions.
- Equipment and tools. Spare parts, backup hardware, event gear and seasonal machinery that does not fit in the office or workshop.
- Seasonal overflow. Peak-season stock that has nowhere to go between November and March — many retailers keep a unit only for Q4 inventory, then downsize.
What a business account actually requires
- Business registration documents. Apple Storage, for example, asks company customers for a Business Registration Certificate and the company chop — individual renters just need an ID and proof of address.
- A tax invoice (發票) for every payment. Apple Storage states it provides official invoices for every payment and accepts credit card, FPS, cheque, Alipay and WeChat Pay — worth confirming with your operator, since an invoice to your business name is what makes the rent easy to claim.
- In-situ upsizing. Confirm the branch lets you move to a larger unit in the same building without ending one contract and starting another — Apple Storage and most chains allow it with a rent adjustment; some small operators charge an admin fee.
- A mailbox or registered business address. Some operators run a mailbox service for online businesses and startups without a physical office — Apple Storage's version includes a professional business address and centralised mail handling, which is a genuinely useful add-on, not a gimmick.
Delivery acceptance, lifts and loading
- Delivery acceptance in writing. Some branches will accept parcels on your behalf, some will not — and couriers will not haul cartons up stairs. Confirm how after-hours deliveries are handled before you commit, and never trust a verbal "no problem".
- Goods lift and corridor width. A unit on the 8th floor with no goods lift means every carton goes up by trolley through a passenger lift shared with other tenants. Apple Storage advertises wide corridors designed for trolley use; ask for the same in writing.
- Trolleys and packing space. Apple Storage offers free trolleys and ladders plus a self-service packing area; StoreFriendly has an in-house logistics team that can move goods into your unit. If you pack and ship regularly, these matter more than a small rent difference.
- Parking and loading bays. A loading bay a van can pull into, and branch parking, change the economics of receiving stock. Apple Storage's Sunrise branch in Chai Wan lists hourly parking — worth checking if you will move stock by car or van.
- 24/7 access and how you enter. Apple Storage, StoreFriendly and Spacebox branches advertise 24/7 self-access by smart access card or facial recognition, year-round. Confirm the entry method and whether staffed hours (for deliveries and payments) differ from access hours.
Business stock you can't store
- Food and perishables. StoreFriendly, Spacebox and Apple Storage all ban food, perishables and items that emit odours — the ban covers everything from cooking oil to inventory with a short shelf life.
- Flammable liquids, gases and solids. Gasoline, kerosene, lighter fluid, camping gas, butane, non-safety matches, charcoal, disposable BBQs and alcohol-based products (including hand sanitiser above a certain strength) are on the standard prohibited list.
- Chemicals and hazardous goods. Paints, thinners, adhesives, pesticides, engine additives, corrosive and toxic substances, and compressed gases — all operators take the same line, citing fire-safety regulations.
- Portable chargers, power banks and lithium batteries. StoreFriendly and Spacebox both list batteries and portable chargers as prohibited — a real issue for sellers of consumer electronics who need to plan around it.
- High-value items in valet (door-to-door) storage. Spacebox's terms exclude items worth over about HK$1,000 per item (jewellery, art) from its door-to-door service, and cap box weight at 25 kg — self-storage units are a different product with different rules.
Insurance for business stock
Business stock is higher in total value and more specific than household goods, and standard policies have real limits. AXA's SmartPlan Shop policy, for example, caps stock in transit at HK$50,000 in any one year, and its "temporary removal" benefit covers contents removed for cleaning, repairing or maintenance for up to three months at a maximum of 10% of the sum insured — it is not written for stock sitting in a storage unit, and shop contents cover excludes stock-in-trade by definition. Home contents policies usually exclude business stock entirely. The practical route is a business contents and stock policy with the storage location declared, bought at replacement value (MSIG, for example, sells business insurance covering contents and stock to full replacement value). Some operators provide no cover at all — Spacebox's terms state it does not insure your items — and valet operators often set per-item caps. Check the insurable limit per unit and per item, whether theft and water damage are covered as well as fire, and whether proof of value (receipts, inventory list) is required to claim. See our mini-storage insurance guide for the gaps that catch businesses out.
Is mini storage a deductible business expense?
Yes, in the normal case. Under the Inland Revenue Ordinance (Cap. 112), all outgoings and expenses incurred in the production of chargeable profits are allowed as deductions (the general rule in s.16), and storage rent for stock, records or equipment is a standard recurring operating expense rather than capital spending. Two practical points make it easy: get an invoice (發票) in your business's name for every payment — Apple Storage says it issues official invoices specifically to simplify accounting and tax filing — and keep your records for at least seven years, which IRO s.51C and the Companies Ordinance (Cap. 622) require of business records anyway. If your business operates as a sole proprietorship, the two-tiered profits tax rates apply to that storage cost the same way as any other expense.
Frequently asked questions
Is mini storage cheaper than a warehouse for a small business?
Not per square foot — warehouse and industrial space runs about HK$9–18 per sq. ft. a month, while urban mini-storage is roughly HK$60–130 per sq. ft. Mini storage is cheaper because of size and terms: you rent 8–42 sq. ft. month-to-month with no fit-out and no multi-year lease, instead of a unit of a few hundred square feet with a 2–3 year lease and deposit. For stock that fits in a unit, the total bill is far lower. The maths flips once you need a few hundred square feet — then a warehouse unit or a third-party fulfilment warehouse (roughly HK$200–350 per pallet a month) usually wins.
Can I store business stock, and will the operator issue a tax invoice (發票)?
Yes to both, but confirm the details. Operators such as Apple Storage run dedicated business-storage accounts that accept stock, records and equipment, and require a Business Registration Certificate and company chop to open one. Apple Storage says it issues official invoices for every payment and accepts credit card, FPS, cheque, Alipay and WeChat Pay. Some operators also offer a mailbox or business-address service for online businesses without a physical office. Ask the same questions of any operator before signing.
What business stock can't go in a mini-storage unit?
Food and perishables; flammable liquids, gases and solids (gasoline, lighter fluid, camping gas, charcoal, alcohol-based products); paints, thinners, pesticides and other chemicals; compressed gases; portable chargers, power banks and lithium batteries; and items that emit odours. These are consistent across operators, who cite fire-safety regulations. Valet (door-to-door) operators add their own rules — Spacebox excludes items worth over about HK$1,000 per item and caps box weight at 25 kg. If you are unsure, check the operator's prohibited-items list in writing before you store.
Can I claim mini-storage rent as a business expense?
Yes. Under s.16 of the Inland Revenue Ordinance (Cap. 112), expenses incurred in the production of chargeable profits are deductible, and storage rent for stock, records or equipment is a normal recurring operating expense. Make it easy to prove by getting an invoice in your business's name for every payment and keeping records for at least seven years — the same retention period IRO s.51C and the Companies Ordinance (Cap. 622) require of business records anyway.
