Buying a Self-Storage Facility
Published 16 September 2025
Why a self-storage purchase can be a property deal, a business deal, or both at once, and the due diligence each version requires.
Self-storage facilities sit in an unusual space between commercial real estate and an operating business. Depending on how the sale is structured, you may be buying the land and buildings only, the operating business and its customer contracts as well, or both together as a single transaction. Understanding which of these you are actually agreeing to buy shapes almost every other part of the due diligence process for a commercial purchase of this kind, and if you eventually plan to sell the facility on, the same distinctions apply to a commercial sale.
Property Purchase, Business Purchase, or Both
If the facility is being sold with an existing customer base, occupancy agreements, a management system and staff, you are effectively buying a business as well as land, and the contract should clearly separate the value attributed to real property from the value attributed to goodwill, plant and equipment, and existing contracts. This distinction affects GST treatment, stamp duty in most states, and what due diligence documents you are entitled to request, since business records such as occupancy rates and revenue history are not automatically disclosed the way title and planning records are. Where the sale includes staff, check what obligations you inherit as the new employer, including accrued leave entitlements, since these are usually adjusted between buyer and seller at settlement rather than simply disappearing.
Zoning and Planning Approval
Self-storage facilities are typically approved under industrial or business zonings, and the specific development approval will usually set conditions around hours of operation, on-site retail or trading activity, signage and traffic management. Check the original development consent and any subsequent modifications to confirm the current use matches what was approved, since an operator who has expanded into retail sales of packing materials, vehicle hire or on-site parking without amending their approval can leave you inheriting a compliance problem. Confirm with the local council whether any further expansion you might be planning, such as adding more storage units or drive-through access, would trigger a fresh planning application.
Reviewing Occupancy Agreements and Records
Storage occupancy agreements are generally licences to occupy rather than leases, but several states regulate self-storage arrangements under specific consumer protection provisions covering notice periods, access rights and the process for dealing with unpaid fees. Request the current occupancy ledger, average occupancy rates over at least the past two years, and a sample of the standard occupancy agreement in use, along with confirmation of how deposits or bonds are held. If occupancy figures are being used to justify the price, ask for the underlying management system reports rather than a summary prepared for the sale. It is also worth confirming what insurance arrangements apply to goods stored on site, since most operators require occupants to hold their own contents insurance and disclaim liability for loss or damage, and any gap in how this has been communicated to existing customers can become your problem after settlement.
Statutory Liens and Abandoned Goods
Most states give storage operators a statutory lien over goods left in a unit where fees are unpaid, along with a defined process for selling or disposing of abandoned goods after notice periods have passed. As the incoming owner or operator, you inherit any goods currently subject to this process, so ask for a list of units in arrears, the stage each has reached in the lien process, and whether any disputes with occupants are ongoing or threatened. This is a practical operational issue rather than a legal technicality, since mishandling the lien process, for example by giving short notice or selling goods before the required waiting period has elapsed, can expose the operator to a claim from the occupant.
Fire Safety and Building Compliance
Storage buildings are typically large, low-cost steel-frame structures, and fire safety compliance, including fire separation between units, sprinkler coverage and exit signage, should be checked against current certification. Request the most recent fire safety or essential services compliance certificate and any outstanding notices from the fire authority or council, particularly if the facility includes climate-controlled units or additional electrical load for security systems and access gates. Security infrastructure, including perimeter fencing, CCTV coverage and gate access control, is often central to how the facility markets itself, so confirm this equipment is owned outright rather than financed or leased separately from the property.
Environmental Considerations on Former Industrial Sites
Because self-storage facilities are frequently developed on former industrial land, a site history and contamination search is worthwhile even where the current use appears low-risk. Ask whether a contamination assessment was carried out at the time of the original development approval, and whether any conditions relating to soil or groundwater monitoring remain in place. This is a similar consideration to the checks recommended for any industrial-zoned commercial purchase, an area explored further in our comparison of commercial conveyancing versus residential conveyancing.
GST Treatment
Whether GST applies to the sale depends heavily on how the transaction is structured. A sale of the land alone is generally subject to GST unless the margin scheme applies, while a sale that includes the operating business, staff and contracts may qualify as a GST-free sale of a going concern if the legislative conditions are met. The ATO's guidance on GST and commercial property is a useful starting point, though the specific facts of a mixed property and business sale should be confirmed with your accountant, since this is general information rather than tax advice.
Getting Due Diligence Right
A self-storage facility can be a straightforward property purchase or a more complex combined property and business transaction, and the contract needs to reflect which one you are actually agreeing to. Working through a proper due diligence checklist for a commercial property purchase, alongside specific checks on occupancy records, zoning conditions and any statutory lien processes underway, gives you a realistic picture of what you are buying before you commit to a settlement date.
