Who Actually Owns Grease Trap Servicing at Your Site: The Manager, the Landlord, or the Agreement?

This is for anyone running a commercial kitchen inside a leased site, a food court tenancy, or a multi-tenant building where it is not obvious who pays for grease trap servicing or who gets the call when it fails an inspection. By the end you will be able to check your lease, your trade waste agreement, and your service contract, and know exactly where your responsibility starts and stops.

A blocked or overflowing trap does not wait for a dispute over whose job it was. The health inspector does not care whether the lease says landlord or tenant. Someone has to answer for it, and in a lot of kitchens nobody has actually checked who that someone is.

Why This Question Comes Up So Often

Commercial kitchens rarely operate in a single-owner building. A food court has one landlord and a dozen tenants sharing plumbing infrastructure. A strip mall restaurant leases from an owner who may or may not have specified trap servicing in the lease. A pub or club might own its building outright but still split kitchen and bar operations across different managers.

In our experience, the quote requests we see come from commercial kitchens across this exact range: restaurants, cafes, pubs, clubs, takeaways and food courts. A striking number of them are requesting a quote not because they know their obligations, but because something has already gone wrong and they are trying to work out who should have booked the service in the first place.

The confusion is not really about grease traps. It is about who signed what, and whether anyone actually read it.

Start With the Trade Waste Agreement, Not the Lease

Before you look at your commercial lease, look at your trade waste agreement with your local water authority. This is the document that legally sets your pump-out frequency and your discharge limits, regardless of what your lease says about maintenance responsibilities.

Most operators do not know they have one, let alone what it specifies. In our experience, a trade waste agreement with the water authority sets the pump-out frequency for a commercial kitchen, and many operators simply do not know theirs. Close that gap before you argue with a landlord or a neighbouring tenant about servicing frequency. The water authority does not care about your internal arrangement. The agreement is between the business operating the kitchen and the authority, not between tenant and landlord.

Sydney Water publishes trade waste requirements for commercial and industrial dischargers, including grease arrestor conditions, on its trade waste page (see external links below). If you cannot locate your agreement, your first move is contacting the authority directly, not guessing at a schedule.

What the Agreement Usually Covers

• Discharge limits. The maximum grease, oil and fat concentration your kitchen is permitted to send into the sewer.
• Pump-out frequency. How often the trap must be serviced, based on trap size and kitchen output, not a generic industry rule.
• Reporting obligations. Some agreements require service records to be kept and produced on request, separate from any lease clause.
• Trap sizing sign-off. Confirmation the installed trap meets the authority's minimum requirement for your kitchen type and covers.

Where the Lease Comes In

Once you know what the water authority requires, the lease determines who pays for it and who is contractually responsible for booking it. This varies enormously between properties, and generic advice about "landlords usually cover base building services" is not reliable enough to act on.

Read the maintenance clause specifically for plumbing and trade waste infrastructure, not just the general repairs section. Some leases place all grease trap servicing on the tenant as an operating cost. Others split it, with the landlord responsible for the trap itself as base building infrastructure and the tenant responsible for regular pump-outs as an operational expense. In food courts, the shared trap serving multiple kitchens is very often the landlord's or centre management's responsibility, with costs recovered through outgoings.

If your lease is silent or ambiguous, that is not a neutral outcome. Ambiguity tends to default to whoever notices the problem first having to fix it. That is usually the tenant, because the tenant is the one standing in the kitchen when it backs up.

The Comparison: Who Typically Holds Responsibility

The options below describe common arrangements. Your actual position depends entirely on your specific lease and trade waste agreement, so treat this as a checklist for what to confirm, not a default answer.

• Single-tenant standalone site, tenant-installed trap. The tenant usually owns the trap and the servicing obligation outright, because the trap was installed as part of the tenant's kitchen fit-out. Check the fit-out approval documents, not just the lease.
• Single-tenant site, landlord-installed trap. The landlord may retain responsibility for the trap as fixed building infrastructure, while the tenant covers the ongoing pump-out cost as a utility-style expense. This split is common but not universal, so confirm it in writing.
• Multi-tenant food court, shared trap. Centre management typically holds the trade waste agreement and books servicing centrally, recovering the cost through tenant outgoings. Ask for the servicing schedule and your share of the cost before you sign, not after a dispute.
• Multi-tenant building, individual traps per kitchen. Each tenant usually holds their own trade waste agreement and books their own servicing, even though the building is shared. This is the arrangement most likely to be assumed rather than confirmed, so check explicitly.
• Franchise or managed operation. Head office agreements sometimes centralise trade waste compliance across sites, meaning the local manager's job is confirming the service happened, not booking it. If that assumption is wrong at your specific site, you find out at inspection time.

What Happens When Nobody Has Checked

Based on what we see in quote requests, most operators only think about the trap when it smells, backs up, or a council or water authority inspection is due. That reactive pattern is exactly how responsibility gaps turn into compliance failures. Nobody is deliberately skipping servicing. Everybody assumed someone else had it covered.

A failed inspection does not accept "I thought the landlord handled that" as a defence. The kitchen operating out of the space is generally the one held to the discharge standard, regardless of who was supposed to book the pump-out. Sorting out the contractual reimbursement afterwards is a separate, slower problem.

The cleaning and compliance side of this is covered in more detail in Grease Trap Regulations in Australia: What You Need to Know, which walks through the discharge and reporting obligations once you know who is holding them.

What to Actually Do This Week

If You Are a Tenant

Pull your lease and find the plumbing and trade waste maintenance clause. If it does not mention grease trap servicing specifically, do not assume silence means someone else's problem. Contact your water authority directly and ask whether a trade waste agreement exists under your business name, and if so, what frequency it specifies.

If You Manage a Multi-Tenant Site

Confirm whether your shared trap has a single trade waste agreement covering all tenants or individual ones per kitchen. If it is shared, document the servicing schedule and the cost recovery method, and tell your tenants. Do not bury it in outgoings nobody reads closely.

If You Are Not Sure Who to Ask

Get the trap serviced and the paperwork sorted first, then resolve the contractual question separately. Get 3 Grease Trap Quotes from licensed cleaners gets you moving while the responsibility question gets settled on paper, rather than leaving the trap unserviced while emails go back and forth.

Pricing Reflects the Same Confusion

Because responsibility is often unclear, pricing conversations get muddled too. Cleaners quote on trap size, servicing frequency, access to the trap and disposal fees. Two kitchens with an identical trap can receive quite different prices on those factors alone, not on who is paying the invoice. Knowing who is financially responsible does not change what drives the cost, but it does determine who should be collecting quotes in the first place.

If you are a licensed contractor who services grease traps and wants a steady flow of quote requests without chasing them down individually, you can apply to join GreaseTrapQuotes or check contractor territory pricing to see how the coverage areas work.

The Bottom Line

Grease trap servicing responsibility is not a matter of common sense or industry convention. It is written down somewhere, either in a trade waste agreement, a lease, or both. The only reliable way to know your position is to read those documents specifically for trap servicing language, not infer it from how similar-looking kitchens seem to operate.

If you have checked and you are the one responsible, or you have decided the fastest path is to get the trap serviced while the paperwork gets sorted, Grease Trap Quotes sends three quotes from licensed cleaners by SMS, usually within about a minute of the request. The service covers Sydney today and is expanding to other Australian cities. Get your quotes and read more on the blog, or find out more about GreaseTrapQuotes.
