Buying a Car Wash or Car Yard Commercial Site

Car washes and car yards are grouped together here because they share a common thread: both are vehicle-related commercial uses with their own specific environmental, licensing and zoning considerations that differ meaningfully from a standard retail or office commercial purchase. The due diligence required, however, is quite different between the two.

Two Different Property Types Under One Banner

A car wash is typically a purpose-built structure with water recycling and wastewater treatment infrastructure, while a car yard is usually a large hardstand or showroom site used for vehicle display and sale, sometimes with a workshop attached. Confirm early which of these you are dealing with, and whether the sale includes any operating business, equipment or vehicle stock, since this affects both the contract structure and the GST treatment of the sale.

Environmental Due Diligence for Car Washes

Car washes use significant volumes of water and chemicals, and most operate under a trade waste agreement with the local water authority governing how wastewater is treated and discharged. Confirm that a current trade waste approval is in place and check whether the site's water recycling system meets current standards, since retrofitting an older system to meet updated requirements can be a significant undertaking. Ask for records of any wastewater testing or compliance issues raised by the water authority, and confirm whether chemical storage on site complies with current dangerous goods requirements.

Environmental Due Diligence for Car Yards

Car yards, particularly those with an attached workshop or that have operated as a service centre in the past, carry a real risk of soil contamination from oil, fuel and solvent use, similar in nature to the concerns raised in our guide to contaminated land considerations for service stations. Even where the current use is limited to vehicle display and sale, ask about the site's history, including any prior use as a service station, panel shop or fuel depot, and whether a contamination assessment has ever been carried out.

Zoning and Planning Conditions

Both car washes and car yards are typically approved under a specific planning permit that addresses traffic management, on-site parking, signage and, for car washes, noise and operating hours given their proximity to nearby homes in many locations. Confirm the current use matches the approval, and check whether any conditions relating to landscaping, stormwater management or hours of operation remain outstanding. If you are planning to add services such as detailing, minor mechanical work or a second wash bay, check with council whether this falls within the existing approval or requires a fresh application.

Reviewing Any Existing Lease or Franchise Arrangement

Many car washes operate under a franchise or licence arrangement with a branded operator, and many car yards are leased to a dealership under a commercial lease with its own rent review and make good provisions. Review the lease or franchise agreement for its remaining term, any requirements around signage or branding, and whether consent is needed from a franchisor or landlord before the sale can proceed. If the property is changing hands with the lease intact, the assignment of that lease needs to be handled formally at settlement, including transfer of any bank guarantee or security deposit held.

Equipment, Hoists and Plant

Car washes typically come with fixed plant such as wash tunnels, vacuum stations, water recycling equipment and payment systems, while car yards may include vehicle hoists, compressors and workshop tools if a mechanical component is part of the operation. Request a schedule listing everything included in the sale, its age and service history, and whether any of it is financed, leased or subject to a security interest that needs to be cleared before settlement. Equipment condition reports are worth obtaining separately from a standard building inspection, since specialised machinery like this falls outside what a general building inspector typically assesses.

Ownership Structures for Commercial Sites

Buyers of car washes and car yards commonly hold the property through a company or trust structure rather than in their own names, particularly where the site is being acquired as an investment separate from the operating business. This decision affects financing, GST registration and how the property is eventually sold, so it is worth settling on a structure before contracts are exchanged rather than partway through the due diligence period, and your accountant should be involved in that decision from the outset.

GST Treatment

Where the property is sold with a lease or franchise arrangement, existing agreements and, in the case of a car yard, vehicle stock and equipment included, the sale may qualify as a GST-free supply of a going concern. Where the land is sold on its own, standard GST or the margin scheme may apply. The ATO's guidance on GST and commercial property explains these categories in more detail, and this is general information rather than tax advice, so confirm the specific treatment with your accountant.

Getting the Contract Right

Because car washes and car yards each carry their own environmental and regulatory profile, the contract should reflect the specific due diligence you have carried out rather than a generic commercial template. Conditions allowing time to review trade waste approvals, environmental history, lease consents and franchise arrangements before the contract becomes unconditional give you room to walk away or renegotiate if something material turns up. If settlement is likely to fall close to a public holiday period, building in a realistic timeframe from the outset avoids the kind of last-minute pressure that can complicate an otherwise straightforward commercial sale or purchase.
