Do You Need a Survey Before Building a Fence in Sydney?

While not legally required under the Dividing Fences Act 1991 (NSW), getting a boundary survey before building a fence in Sydney is strongly recommended. A survey costs $800-$1,500 and prevents costly disputes with neighbours. Building a fence on the wrong boundary can cost $5,000-$20,000+ to fix, making a survey a smart investment.

Is a Boundary Survey Legally Required for a Fence?

No, the Dividing Fences Act 1991 (NSW) does not require a survey before building a fence. However, you are legally responsible for ensuring your fence is built on the correct boundary. If your fence encroaches on a neighbour's property, you may be required to remove it at your expense.

How Much Does a Fence Survey Cost?

A boundary identification survey for fence purposes in Sydney costs $800 to $1,500. This locates your boundary corners so you know exactly where to build your fence. The survey typically takes 5-7 business days to complete.

What Happens If Your Fence Is on the Wrong Boundary?

If your fence is built on the wrong boundary, you may need to remove it and rebuild in the correct position. This can cost $3,000-$10,000+ depending on the fence type. Your neighbour could also take legal action for encroachment. Getting a survey first prevents these problems.

Can You Use Your Title Plan to Find Your Boundary?

Title plans and online maps show approximate boundaries only - they are not accurate enough for fence construction. Boundaries can only be legally determined by a registered surveyor. Using a title plan to position your fence could result in building on the wrong line.
