Fencing is another area where townhouses are completely different from apartments. Most apartment buildings have no fences at all. Townhouse schemes have fences everywhere โ€” boundary fences with neighbours, fences between lots, fences around courtyards, fences on common property. Each type follows different rules.

What we're talking about

The fencing question in a townhouse scheme generally involves three different kinds of fence:

Typical position

Usually OC

  • External boundary fences (street side and shared with neighbours)
  • Fences on common property
  • Common gates and entry features

Usually owner

  • Internal fences within the lot (shown inside the lot boundary)
  • Garden screens, trellises and similar features inside courtyards
  • Damage caused by the owner (e.g. car backing into a fence)
  • Decorative additions to a common fence (often unapproved)

Often grey

  • Fences between two lots within the same scheme
  • Fences shown on the plan exactly on the lot boundary
  • Old fences replaced by previous owners without records
  • Decorative changes (paint colour, height, materials)

โš  Townhouses and apartments are very different here

Apartment buildings usually have no boundary fence to worry about โ€” the building is the boundary. Townhouse schemes have actual boundary fences with the neighbours next door. Whether the Dividing Fences Act 1991 (NSW) applies depends on where the fence sits โ€” ask us before acting.

Within a townhouse scheme, start with the strata plan and by-laws for internal fences between courtyards or around private yards.

Grey areas and common disputes

External fence shared with a neighbour outside the scheme

When the fence between your scheme and the next-door property needs repair or replacement:

Fences between two lots within the same scheme

This is the trickiest category. The fence sits on or near the boundary between two lots. Depending on how the strata plan is drawn:

If the plan shows the fence on common property between the two lots, it's the OC's. If the plan shows it inside a lot, it's that owner's. Honest answer: it can be genuinely unclear in older plans and may need legal advice if there's a dispute and a real repair cost.

Painting, height changes and replacing materials

Even when a fence is "yours" to maintain, you usually can't change it without OC approval. Painting a common fence a different colour, raising its height, or replacing palings with colorbond can all affect common property or the scheme's appearance, and need approval first โ€” ask us which route applies.

Damage caused by a vehicle, tree or activity

If a fence was damaged by a specific cause โ€” a vehicle, a contractor, a tree from one lot โ€” the cost can shift to the party responsible regardless of which side of the fence they're on.

Decorative additions and lattice

Lattice work, screens and trellis attached to a common fence by a lot owner can be a sore point. They're usually not approved, often not removable cleanly, and tend to fail over time. If you want to add screening for privacy, ask for OC approval and consider a free-standing internal structure that doesn't attach to the common fence.

Start with the strata plan

For any fence inside the scheme, the registered strata plan and by-laws decide who's responsible. For a fence on the scheme's outer boundary, whether the Dividing Fences Act applies depends on where the fence sits โ€” ask us before acting.

Practical next steps

  1. Identify which kind of fence it is โ€” external boundary, common property fence within the scheme, or fence inside or between lots.
  2. Check the strata plan for the lot boundaries.
  3. Photograph the issue, with the surrounding area visible.
  4. For external boundary fences, let your strata manager deal with the neighbour rather than owners doing it themselves.
  5. For internal fences, raise it in writing with your strata manager. If responsibility is unclear in the plan, ask for the position to be set out in writing.
  6. Don't just pay and hope. If you pay for work on a common property fence without OC approval or an NCAT order, you're unlikely to get the money back (Colman [2025] NSWSC 63). Ask first, in writing.

This isn't legal advice. Boundary disputes and fence disputes are some of the most fact-specific issues in strata. The strata plan and any registered by-laws come first; for external fences, ask us whether the Dividing Fences Act applies. If a repair is significant and responsibility is contested, get advice before committing.
