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:
- External boundary fences โ between the scheme and the neighbour next door, or between the scheme and the street
- Internal common property fences โ running through the scheme between common areas, or marking off common gardens
- Fences between or around lots โ the most variable, including fences around courtyards
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)
โ 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:
- Whether the neighbour shares the cost, and whether the Dividing Fences Act applies, depends on where the fence sits โ ask us before acting
- The OC needs to approve the spending before anything is agreed with the neighbour
- Your strata manager should handle the correspondence on the OC's behalf โ owners shouldn't be negotiating directly with the neighbour
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:
- The fence may sit entirely on common property (OC's responsibility)
- It may sit exactly on the lot boundary (one of the more disputed scenarios)
- It may sit inside one lot (that owner's responsibility, even though the fence benefits the other)
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.
