Easements Explained

An easement is a legal right registered on a property's title that allows another party — usually a utility provider, council, or sometimes a neighbour — to use a specific portion of your land for a defined purpose. You still own the land, and you still pay rates on it, but your ability to build, place structures, or even plant certain trees within the easement area is legally restricted. For anyone buying a block to build on, understanding easements before you commit is one of the most important steps you can take.

The reason easements matter so much is simple: they can directly determine where your house can sit on the block. If an easement runs through the middle of your land, it may force your builder to reposition the house, reduce its size, or change the design entirely. In some cases, a block that looks perfect on a real estate listing can become far less buildable once you read the title and discover what lies beneath.

What an Easement Actually Allows

An easement grants a specific right to a specific party. It does not transfer ownership of the land — it grants a right of use. The most common types you will encounter on residential land in Australia include:

• Sewer and drainage easements — give the water authority the right to access, maintain, repair and replace underground pipes. These are the most common easements on residential blocks.
• Stormwater easements — allow stormwater to flow through your land via underground pipes or overland paths. Often found on sloping blocks or in low-lying areas.
• Powerline and electricity easements — give the electricity provider the right to access and maintain overhead or underground power infrastructure.
• Right of way (access) easements — give a neighbour or the public the right to cross your land to access their property or a road.
• Party wall easements — relevant for townhouses and duplexes where a shared wall straddles the boundary.
• Telecommunications easements — for underground or overhead phone and data infrastructure.

Each easement type comes with its own set of restrictions. A sewer easement may prohibit any structure with footings within the easement width. A powerline easement may restrict building height and require minimum clearances. A right of way easement may prevent you from fencing across the access path. The specific restrictions are defined by the authority that holds the easement, not by a universal rule.

Who Has Rights Over an Easement

Every easement has two parties: the servient tenement (your land, which bears the burden) and the dominant tenement or authority (the party that benefits). Understanding who holds the rights matters because it determines who you need to deal with if you want to build near or over the easement.

If you are unsure who holds an easement on your block, the Certificate of Title will name the authority or party. Your conveyancer can also identify this during the conveyancing process.

Can You Build Over an Easement?

The short answer is: generally no, but it depends on the authority and the type of structure.

Most water authorities and councils prohibit permanent structures — houses, garages, sheds, pools, retaining walls with footings — within a sewer or drainage easement. The reason is straightforward: if the authority needs to excavate to repair a pipe, any structure above it would need to be demolished, and the authority will not accept that liability.

Some authorities offer a build-over or encroachment approval process for minor structures. For example, some councils may permit a lightweight carport or a pergola over a shallow stormwater easement, provided the structure can be easily removed and does not impose load on the pipe. However, this is never automatic. It requires a formal application, engineering drawings, and a fee — and approval is not guaranteed.

How Easements Affect House Positioning

Easements can have a significant impact on where your house sits on the block. Here is how:

• A sewer easement running across the rear of a block may push the house forward, reducing backyard space.
• An easement running diagonally through the centre may make certain house footprints impossible without redesign.
• On narrow blocks, a side-boundary easement can consume enough width to prevent a double garage or side access.
• On corner blocks, easements on both street frontages can severely limit the building envelope.
• An easement may also affect where your driveway crossover can be located, which in turn affects garage positioning.

If you are working with a volume builder who offers a standard design, the design may need to be modified to fit around the easement. Modifications can add cost and delay. If you are building a custom design, your architect or building designer will need to work around the easement from the start.

Easements and Pools, Sheds, Retaining Walls

It is not just the house that is affected. Many secondary structures are also restricted within easement areas:

What Documents Show Easements

Before you buy a block or sign a building contract, you should review these documents:

• Certificate of Title — lists registered easements and references the relevant plan.
• Deposited Plan (DP) or Plan of Subdivision — shows the physical location and dimensions of easements on the block.
• Section 88B Instrument (NSW) or similar covenant/easement documents — details the terms and restrictions of the easement.
• Title search or property report — available from your state's land registry service.
• Council property certificate — may reveal unregistered or proposed easements.

Your conveyancer or solicitor should obtain and review these documents during the conveyancing process. If you are buying land in a new estate, the developer's sales contract and the plan of subdivision will show easements.

What Happens If Your House Footprint Conflicts

If your builder or certifier discovers that your proposed house design overlaps an easement, you have several options — none of which are quick or free:

1. Redesign the house to avoid the easement entirely. This is the most common and least expensive option, but it may reduce house size, change the layout, or require a non-standard design.
2. Apply to the authority for a build-over-easement approval. This requires engineering drawings, an application fee (often $500–$3,000+), and can take 4–8 weeks. Approval is not guaranteed.
3. Apply to have the easement relocated or removed. This is expensive, requires the authority's consent, and can take months. It is rarely practical for sewer easements.
4. Choose a different block. If you have not yet purchased, walking away may be the most cost-effective decision.

How Requirements Differ Between Authorities

There is no single national standard for easement restrictions. Rules vary by:

• State — each state has its own land title legislation and water authority structure.
• Water authority — Urban Utilities in SEQ has different build-over guidelines to Sydney Water or Yarra Valley Water.
• Council — local councils set stormwater and overland flow easement rules, which can vary even within the same city.
• Developer — in new estates, the developer may impose additional easement-like restrictions through covenants or design guidelines.
• Age of infrastructure — older easements may have less documented restrictions, while newer estates have precisely defined easement terms.

Always check with the specific authority that holds the easement on your block. Do not rely on general advice or what a friend experienced in a different council area.

What This Can Mean for Your Build

An easement can affect your build in three main ways: it can reduce the usable building envelope, it can force design changes that add cost, and it can delay approvals if you need to negotiate with the authority. In the worst case, an easement that runs through the middle of a small block can make the block effectively unbuildable for a standard home design.

On the other hand, an easement along a side or rear boundary is extremely common and may have minimal impact if your house design already keeps clear of the boundary. The key is knowing about the easement early — before you commit to a design or a builder.

Common Mistakes

• Buying a block without reading the title and discovering an easement only when the builder surveys the site.
• Assuming a small easement will not matter, only to find it forces a complete redesign.
• Assuming you can build over an easement because a neighbour did — different authorities, different rules.
• Forgetting that easements affect pools, sheds and retaining walls, not just the house.
• Not checking whether the developer's design guidelines impose additional easement-like restrictions beyond the title.
