Zero-lot boundary properties
Some new developments have small blocks that allow building close to the boundary. A zero-lot boundary helps maximise available building space on the property.
Zero boundary allotments do have a small setback from the boundary up to 250 millimetres. This keeps the fascia, gutter, termite system, and footings within the boundary. They can also include allowances for systems such as termite barriers and footings.
Protecting your boundary wall
Check the footing design of your boundary wall with your builder and design engineer. They will ensure it can withstand possible impacts from the property next door.
Swimming pools, gardens, and trees located close to the boundary wall can also affect your footing.
You cannot place fill material against the boundary wall or structure. This can damage the termite barrier or cause water to enter.
Fire separation requirements
Walls built near the boundary must meet a fire resistance level of 60 minutes. You cannot have openings such as doors or windows in the wall. Local councils enforce compliance with the National Construction Code and local planning rules for fire separation. For more information, refer to the National Construction Code.
Maintenance-free boundary structures
Buildings close to a boundary are hard to access for painting, repairs, or sealing. Work often requires entering a neighbour’s property. Buildings and structures located within 750 millimetres of a boundary must be maintenance-free. This means you must use materials that won’t need ongoing painting, sealing, or upkeep.
Acceptable finishes include unpainted or untreated masonry or prefinished steel sheeting. This applies to boundary walls, dividing fences, and similar structures. This reduces ongoing maintenance risks and avoids disputes.
Accessing a neighbour’s property
You must get written consent from your neighbour before accessing their property. This applies even if easement rights allow entry. Consent is needed not just for minor work, but also for:
- ongoing inspections
- termite treatment
- gutter cleaning
- repairs.
Encroachment on built-to-boundary structures
Neighbours of built-to-boundary structures cannot attach or fix anything to them. This would be an encroachment, as it crosses onto your property without consent. For example, a neighbour cannot attach a fence, shade sail, or clothesline.
Neighbour disputes
If encroachment or another dispute occurs, such as a neighbour refusing access to their property, try speaking with them first to resolve the issue. If you cannot reach an agreement, you can:
