Ever driven past a new housing estate and wondered why a huge, old gum tree was left standing in the middle of a block? Or why the developer had to build a public walkway along the creek? Often, the answer is a little-known but powerful tool called a Section 173 Agreement.
It’s a legal contract made under the Planning and Environment Act 1987 in Victoria, and it’s a bit like a permanent set of rules attached to a property’s title. These rules aren’t just for the current owner, they stay with the property, so anyone who buys it in the future must follow them too.
In Melbourne, councils use these agreements to make sure specific development conditions are met long after a planning permit is approved. This article will walk you through what these agreements are, why they matter, and what you need to know as a property owner or developer.
Understanding the Basics

A Section 173 Agreement gets its name from Section 173 of the Planning and Environment Act 1987. It’s a formal, legally binding contract between a landowner and the local council.
Sometimes, another body like Melbourne Water might be involved if the agreement affects their assets or area of responsibilty.
So, why have one? Sometimes, the usual conditions on a planning permit aren’t enough to get the job done. The council might need a stronger, more permanent way to lock in certain commitments.
Common reasons include:
- Protecting native vegetation that’s important to the local environment.
- Coordinating infrastructure works like shared access roads or drainage upgrades.
- Limiting how many lots you can create in a subdivision.
- Securing the delivery of affordable housing, as noted in State Government planning guidance.
Because it’s registered on the property title, the agreement gives the council a reliable way to make sure these promises are kept for the long haul.
Why a Section 173 Agreement May Be Required

A council might require a Section 173 Agreement in a variety of situations where they need to lock in ongoing rules for a piece of land. You might find yourself needing one if:
- Your land has special features. If your property contains native bushland, a heritage building, or a waterway, the agreement can set out clear rules on how to protect and manage them.
- The property is in a sensitive area. For land in a flood-prone or environmentally significant zone, an agreement might set minimum floor heights or limit what you can build to keep people and nature safe.
- Future development needs to be controlled. The council might want to prevent further subdivision of the land or fix the exact spot where a house can be built (the “building envelope”). This helps maintain the character of an area.
- You’re a developer contributing to the community. For new housing projects, an agreement can formalize your contribution of funds or land for things like local roads, parks, or community centres.
- The rules need to outlive a permit. A planning permit can expire, but the obligations in a Section 173 Agreement last until they are formally ended. This is a key point highlighted in the Guide to Victoria’s Planning System – Chapter 8.
Basically, if the council wants to set rules that last, an agreement is the tool they’ll use.
Key Parties Involved
Putting together a Section 173 Agreement is a team effort. Here are the main players and the roles they take on.
| Party | Role in the Agreement |
| Local Council | Usually initiates, drafts, negotiates, and enforces the agreement to align with local planning goals. |
| Landowner | The property owner who agrees to the conditions, which then become legally tied to their land. |
| Referral Authority | An external body, like Melbourne Water or VicRoads, that provides input if the agreement affects their infrastructure or interests. |
| VCAT | The Victorian Civil and Administrative Tribunal steps in to resolve disputes or approve changes when the main parties can’t agree. |
VCAT’s role is particularly important for breaking deadlocks when an agreement needs to be amended.

Legal and Practical Implications
Registration on Land Title
A Section 173 Agreement isn’t just a handshake deal. It’s formally recorded on your property’s land title, making it a permanent part of the official record. This registration is what makes the agreement so powerful and long-lasting.
Effect on Future Landowners
Because the obligations “run with the land,” any new owner automatically inherits the same responsibilities.
This can:
- Influence the property’s sale price.
- Affect its appeal to potential buyers.
- Limit future renovation or development options.
For example, if an agreement says you can’t build a second storey, a future owner can’t just ignore that rule. They’re bound by it, just like you were.
Duration
These agreements can be set up to last forever or for a specific time. If no end date is included, it stays in force indefinitely. The only way to end it is through a formal process to amend or remove it from the title, which requires the council’s approval.
The bottom line is that a Section 173 Agreement creates long-term duties that follow the property, not the person.
Common Conditions in a Section 173 Agreement
An agreement can cover a wide range of topics, but a few common conditions pop up regularly across Victoria.
- Environmental protection measures: You might be required to fence off and protect native vegetation, manage stormwater to keep local creeks clean, or set aside part of your land as a conservation area.
- Infrastructure contributions: Developers are often asked to help pay for local infrastructure. This could mean building new roads, upgrading drainage, or connecting new homes to services. Think of it as helping the neighbourhood services keep up with the growth your project creates.
- Land use restrictions: An agreement can specify exactly how land can be used. It might, for instance, limit a property to residential use only, preventing any commercial activity from taking place.
- Affordable housing provisions: In some Melbourne developments, an agreement might require a certain percentage of homes to be sold or rented as affordable housing at below-market rates.
- Subdivision controls: If you are creating new lots, the agreement might control how this happens. It could set a minimum lot size or state that once subdivided, the new lots cannot be split again.
Process for Establishing a Section 173 Agreement

Setting up an agreement generally follows these steps, though the specifics can differ between councils.
- Initiation: The need for an agreement usually comes up during planning permit negotiations with your local council.
- Drafting: The council’s lawyers will prepare a draft agreement. They may consult with referral authorities if the agreement affects things like water or roads.
- Review and Negotiation: You and your legal team get to review the draft. This is your chance to clarify obligations, check timelines, and negotiate any terms that don’t seem right.
- Execution: Once everyone is happy with the terms, all parties sign the document. This includes you, the council, and any other relevant authorities.
- Registration: The signed agreement is lodged with Land Use Victoria and registered on your property’s title. This is the final step that makes it legally binding on the land.
Amending or Ending a Section 173 Agreement
An agreement isn’t always set in stone. As circumstances change, you may be able to adjust or even end it.
Amending a Section 173 Agreement
If you want to change the terms, you’ll need the consent of all parties involved – typically you and the local council. The process involves drafting a formal variation, having everyone sign it, and registering the updated agreement on the property title. If you can’t reach an agreement, you may need to apply to VCAT to settle the matter.
Ending a Section 173 Agreement
You can end an agreement completely if all parties agree to it, or by an order from VCAT. An order from VCAT is usually sought when the agreement no longer serves a practical purpose – for example, if the development it related to is finished and all conditions have been met.
No matter which path you take, the agreement must be formally removed from the property’s title to avoid issues for future owners.
How to Check if a Property is Subject to a Section 173 Agreement
Before you buy or develop property in Victoria, it’s smart to find out if a Section 173 Agreement is attached. Here’s how:
- Search the land title: An agreement will be listed on the property’s title under “notifications” or “encumbrances.” You can order a copy of the title from the Victorian Land Registry.
- Review the planning certificate: A planning certificate, which is often part of the conveyancing process, will state whether the land is subject to an agreement.
- Contact the local council: If you’re still unsure, talk to teh council’s planning department. They can check their records and give you the details.
- Get the Section 32 reviewed by a professional: If you want to be 100% sure, get the contract reviewed by a conveyancer. We offer free Section 32 reviews here.
Doing this homework can save you from a major headache later, like discovering you can’t build that extension you’d been dreaming of.
Risks and Considerations
While an agreement might be the key to getting your project approved, it’s important to be clear-eyed about what you’re signing up for.
- Financial impact: You could be on the hook for costs like building new footpaths, upgrading drainage, or making cash contributions for community facilities. These expenses can add up and might not have been in your original budget.
- Development limitations: The agreement can place firm restrictions on your property. It might limit the size or height of a building, dictate its location, or control how it can be used. These rules stick with the property and will apply to any future owner.
- Time delays: Negotiating terms with the council, drafting the legal document, and getting it registered on title all take time. This can delay your construction schedule and have a knock-on effect if you’re working with builders on a tight timeline.

Practical Tips for Melbourne Property Owners and Developers
If you’re dealing with a Section 173 Agreement in Melbourne, a bit of forward planning can save you a lot of trouble.
First, do your homework before you buy. Get a copy of the title and ask the council if any agreements apply. Read the terms closely, as even a small clause can affect your plans.
Next, budget for compliance costs early on. The costs for landscaping, design requirements, or infrastructure contributions can be significant. Plan for them in your budget and timeline from the very beginning.
It’s also a good idea to get legal advice. A property lawyer can explain your obligations in plain English, highlight any risks, and help you negotiate better terms.
Finally, talk to the council planners early. If you understand what the council is trying to achieve, you might find a way to meet their needs while keeping your project on track. Open conversations can prevent roadblocks later.
A Final Word
A Section 173 Agreement is more than just paperwork; it’s a legal commitment that shapes the future of a property for years, or even decades. Since it’s attached to the land itself, its rules are binding on anyone who owns it.
For any property owner, developer, or buyer in Melbourne, understanding what an agreement contains is essential. It can dictate everything from how you subdivide to what you can build.
Because these agreements are not easily changed, it’s best to:
- Read and understand every clause before you sign.
- Get professional advice to clarify your obligations.
- Think about how the rules could affect your future plans for the land.
Handled correctly, a Section 173 Agreement can provide certainty for everyone and help protect a neighborhood’s character. But if you walk in unprepared, it can lead to unexpected restrictions and costs. Taking the time to be informed is the best way to make smart decisions about your property.
