Understand the Responsibilities of a Shared Boundary

A shared fence can help maintain privacy, define property boundaries, and clearly separate neighbouring homes. When planning a boundary fence Sydney project, neighbours should understand their responsibilities, discuss the proposed work, and agree on practical arrangements before repairs or replacement begin. Clear communication can prevent misunderstandings, manage costs, and ensure the finished fence suits both properties' needs.

Confirm the Property Boundary

Check the Existing Fence Position

An existing fence does not always sit precisely on the legal boundary. Before arranging repairs or replacement, neighbours should check available property documents and, where necessary, confirm the fence's position.

Seek Professional Advice if Required

If the boundary is unclear or disputed, a registered surveyor may be able to establish the correct position. Confirming this information before construction can help reduce the risk of placing a new fence incorrectly.

Discuss the Proposed Work Early

Agree on the Type of Work

Neighbours should discuss whether the fence requires minor repairs, partial replacement, or complete reconstruction. Comparing the condition of the existing structure can help both parties understand why work may be necessary.

Consider Each Property's Needs

One neighbour may prioritise privacy, while the other may be more concerned about maintenance, appearance, or access. Discussing these preferences early can help identify a practical solution that respects both properties.

Understand Shared Fencing Costs

Clarify the Proposed Budget

Fencing costs can depend on the material, fence length, height, site conditions, access, removal requirements, and installation complexity. A written quote can help neighbours understand the expected costs before agreeing to the work.

Discuss Cost Contributions

In New South Wales, the Dividing Fences Act 1991 generally governs shared dividing fences. Neighbours may have obligations to contribute to the cost of a sufficient dividing fence, subject to the circumstances and applicable legal requirements. If one neighbour chooses a more expensive fence, the cost arrangements may differ.

Neighbours should review the relevant NSW requirements or seek legal advice if they are uncertain about their responsibilities.

Choose Suitable Fencing Materials

Compare Available Options

Timber, COLORBOND®, aluminium, and other fencing materials vary in appearance, maintenance needs, and cost. Comparing options can help neighbours choose a fence that suits the location and their agreed budget.

Consider Long-Term Maintenance

The material should suit the property's exposure to weather and expected use. Discussing future maintenance can also set realistic expectations for cleaning, repairs, and ongoing care.

Follow the Appropriate Notice Process

Communicate in Writing

Before work begins, neighbours should document the proposed fence type, location, estimated cost, and intended timing. Written communication can provide a useful record of what has been discussed and agreed.

Understand Formal Requirements

Under NSW law, a neighbour who proposes work on a dividing fence will generally need to provide written notice to the adjoining owner, subject to the circumstances and any applicable exceptions. If you can't reach an agreement, formal dispute resolution processes may be available through the relevant NSW authorities.

Neighbours should check current requirements before proceeding, particularly if the other owner disagrees with the proposal.

Plan Access and Installation

Coordinate Site Access

Some projects require access to areas near the neighbouring property, especially when removing an old fence or installing posts. Discuss and arrange any necessary access before the contractor arrives.

Prepare for Site Conditions

Sloping ground, retaining walls, trees, drainage, and underground services can influence the installation process. Identifying these conditions in advance can help the contractor plan the work and reduce unexpected complications.

Select a Suitable Fencing Contractor

Request Clear Written Quotes

A detailed quote should identify the proposed materials, measurements, installation work, removal of the existing fence, disposal costs, gates, and any exclusions. Comparing equivalent quotes helps neighbours assess value rather than choosing solely on the lowest price.

Confirm the Project Arrangements

Before accepting a quote, neighbours should clarify the work schedule, payment responsibilities, warranty details, and process for approving additional costs. These arrangements can help keep the project organised from start to finish.

Maintain a Positive Neighbour Relationship

Keep Communication Respectful

Fence disagreements can become stressful when expectations differ. Calm discussions, clear records, and a willingness to consider reasonable alternatives can make it easier to reach an agreement.

Record the Final Decision

Once the details are settled, keep a written record of the agreed design, costs, contractor, and schedule. This helps both parties refer to the same information throughout the project.

Repairing or replacing a shared fence requires more than selecting materials and arranging installation. Neighbours should confirm the boundary, discuss costs, understand applicable NSW requirements, compare quotes, and agree on access and project details before work starts. A cooperative, well-informed approach can help protect both properties, reduce misunderstandings, and create a dividing fence that meets everyone's needs.

Frequently Asked Questions

The quote should outline materials, measurements, labour, removal and disposal of the old fence, site preparation, gates, additional charges, and any exclusions.

Can a neighbour choose a more expensive fence design?

A neighbour can propose a preferred design, but the other owner's cost contribution may depend on what is reasonably required for a sufficient dividing fence and the applicable legal arrangements.
