Shared Pool Fencing Between Neighbouring Properties

What This Requirement Covers

Shared pool fencing between neighbouring properties covers the design, construction and location of safety barriers where a swimming pool on one property adjoins or is close to another property. The requirement exists to prevent unsupervised access by young children to the pool area and to reduce drowning risk by ensuring a continuous, child-resistant barrier is provided for the full extent of the hazard. It applies to property owners, designers, builders, certifiers and occupiers responsible for pools and their boundaries where a pool could be accessed from an adjoining lot.

Under the National Construction Code (NCC) and the referenced Australian Standards, a pool barrier may be an on-property fence or incorporate a shared boundary element where that element can meet the same functional and dimensional criteria as an individual pool fence. The barrier must be continuous, of adequate strength and rigidity, and have self-closing, child-resistant gates or latches as required by the relevant NCC provisions and AS 1926.1 (the pool safety barrier standard).

Key Requirements

1. Depth threshold: Requirements apply to swimming pools with a depth of water more than 300 mm, as specified in NCC Volume One and NCC Volume Two (see H7 and G1 provisions). Refer to NCC Volume Two, Part H7 and NCC Volume One, Part G1 for jurisdictional application. (NCC Volume Two - Part H7; NCC Volume One - Part G1)
2. Continuity and purpose: The barrier must be continuous for the full extent of the hazard, restrict young children from the pool and immediate surrounds, and be strong and rigid to withstand foreseeable impact (NCC Volume One - G1P2; NCC Volume Two - H7P1).
3. Standards reference: Technical construction requirements are satisfied where barriers comply with AS 1926.1 (Design and construction of pools, pool fencing) and AS 1926.2 where applicable; water recirculation systems must comply with AS 1926.3 (NCC Volume One G1D2; NCC Volume Two H7D2).
4. Boundary / shared fences: AS 1926.1 identifies that a barrier may be formed by a boundary barrier provided it meets the same dimensional and construction requirements as any other pool barrier (see clause 2.3.1 of AS 1926.1 referenced in NCC guidance). The NCC notes that out-of-ground pool walls and above-ground pool walls (including inflatable pools) are not considered effective barriers (NCC Volume Two explanatory notes).
5. Dimensions and clearances (from AS 1926.1): Key dimensional rules to be met for a compliant barrier or boundary barrier include (extracts and typical values from AS 1926.1):
6. Minimum barrier height: 1200 mm above finished ground level on the pool side (or as specified for the particular configuration in AS 1926.1).
7. Maximum gap under barrier: 100 mm maximum clearance between ground and barrier where a child could otherwise get under the fence (typical AS 1926.1 requirement).
8. Maximum vertical or horizontal bar spacing: 100 mm (for vertical or horizontal members where a child might pass through), with larger openings restricted by additional geometry rules in AS 1926.1.
9. Climbable zones: Any objects, structures or projections within 900 mm of the outside of the barrier that would assist climbing must be removed or the barrier adjusted to prevent use as a foothold (AS 1926.1 climbable zone provisions).
10. Gate requirements: Gates must be self-closing and self-latching, with latches located not readily operated by young children - typically with latch release at least 1500 mm above ground or an equivalent child-resistant mechanism as described in AS 1926.1.
11. Strength and rigidity: The barrier must be constructed to resist foreseeable impact from people; where structural design is necessary, relevant building standards and structural codes apply (refer to general structural practice such as AS 1684 for timber framing or AS 4100 for steel where applicable to fence posts and supports).
12. Applicable building classes: The NCC provisions and AS standards apply to swimming pools associated with residential and other classes where the pool depth exceeds 300 mm, including Class 1, Class 2, Class 3 and Class 4 parts as identified in the NCC (see NCC Volume One - G1D2/NCC Volume Two - H7D2).
13. Code references to cite: NCC Volume One - G1P2 and G1D2; NCC Volume Two - H7P1 and H7D2; AS 1926.1 (Design and installation of safety barriers for swimming pools), AS 1926.2, AS 1926.3. When structural members are designed to support fences, use relevant standards such as AS 1684 or AS 4100 where materials and structural design are applicable.

Residential vs Commercial

1. Residential (Class 1 and Class 10A accessory pools): The NCC requires barriers for pools deeper than 300 mm; the usual compliance path is to meet AS 1926.1. For freestanding domestic pools, a boundary fence that forms part of a shared boundary may be accepted when it meets all AS 1926.1 dimensional and latch requirements. Local pool safety or swimming pool acts and regulations may add administrative or inspection requirements for private residences (see state schedules and local regulation references below).
2. Commercial and multi-occupancy (Class 2-9): Pools associated with Class 2, 3 or Class 4 parts also require barriers meeting AS 1926.1/AS 1926.2 and the NCC may invoke additional or jurisdiction-specific provisions (for example, children’s services or commercial pools will often require compliance with AS 1926.2 and AS 1926.3 for recirculation equipment). For shared or communal pools in multi-occupancy buildings, the pool barrier design must also consider means of escape, fire service and access regulations where those overlap with building code obligations.

Exceptions and Exemptions

1. Pools or water features with depth 300 mm or less are typically exempt from these barrier requirements under the NCC definition; however, some state legislation may still regulate shallow water features.
2. Out-of-ground or above-ground pool walls (including many inflatable pools) are not accepted as effective barriers under NCC guidance unless they are specifically designed and constructed to comply with AS 1926.1 (NCC explanatory notes specify these are generally not considered effective barriers).
3. Alternative solutions or performance solutions may be accepted where a designer demonstrates equivalent or superior safety performance to the prescriptive AS 1926.1 requirements - subject to approval by the relevant building surveyor or certifier and consistent with the NCC performance provisions.

State and Territory Variations

1. The NCC is a national code, but each state and territory may adopt schedules or separate legislation that modifies administration or imposes additional requirements. Notable points:
2. New South Wales: The NCC provisions are applied in conjunction with the Swimming Pools Act 1992 and the Swimming Pools Regulation 2018; NSW H7D2 and G1D2 specifically reference AS 1926.1 and AS 1926.2 for technical construction requirements (NCC Volume Two - NSW H7 provisions; NCC Volume One - NSW G1 provisions).
3. Victoria: The NCC includes a Victoria-specific G1P2 replacement that requires barriers for certain pools and references AS 1926.1 and AS 1926.2 where applicable (NCC Volume One - VIC G1P2/G1D2).
4. Queensland, Western Australia, South Australia, Tasmania, ACT and NT: Each jurisdiction may have specific pool safety legislation or local council rules that operate alongside the NCC. The NCC guidance notes to Part H7 and G1 say to check state schedules; for example, Queensland has its own schedule and administrative rules that can affect enforcement or additional fencing requirements. Always verify the relevant state schedule in NCC Volume One (Schedules 4-12) and local legislation.

Note: State schedules within the NCC and separate state Acts and Regulations may prevail where inconsistent with the NCC - always check the state schedule and the local swimming pool safety legislation.

Practical Compliance Tips

1. Confirm the water depth: Verify the pool's maximum water depth is more than 300 mm before applying AS 1926.1 requirements. If under 300 mm, check local regulation for any additional rules.
2. Treat boundary fences as pool barriers only if they fully comply: A shared boundary fence can form the pool barrier only when it meets the 1200 mm minimum height, gap limitations, gate latch heights and climbable-zone rules in AS 1926.1.
3. Avoid climbable objects near the outside of the barrier: Keep gardens, furniture, bins and trellis at least 900 mm away from the outside face of the barrier or otherwise ensure they cannot be used to climb over the fence (AS 1926.1 climbable zone guidance).
4. Select gate hardware that meets child-resistant criteria: Use self-closing hinges and self-latching mechanisms with the latch release positioned out of reach of young children (commonly 1500 mm or higher, or as per AS 1926.1), and test gates to ensure reliable closing and latching every time.
5. Check shared-owner responsibilities early: Where a shared boundary is used, confirm ownership and maintenance responsibilities in writing between neighbours so that the barrier remains compliant and maintained over time.
6. Document compliance for certifiers and inspectors: Keep drawings, AS 1926.1 compliance checks, photos and any performance solution evidence ready for a certifier or local pool safety inspector; include measurements of heights, gaps, latch positions and clearances.
7. When in doubt, pursue a performance solution or seek certifier advice: If an existing boundary feature cannot meet prescriptive rules, engage a registered certifier or a pool safety auditor to propose and certify an alternative solution that demonstrates equivalent protection.
