Pools, spas and the barrier rules
Pool barriers are life safety law, inspected by your council, and they shape your entire garden layout — gates, levels, climbable objects, planting near the fence. Design the barrier first, then the garden around it.
A pool barrier is not a fence. It is life-safety law, and you are personally on the hook for it every day the pool holds more than 300 mm of water — not just on the day it was signed off. Under regulation 50(2) of the Building Regulations 2012, each owner and occupier must ensure a compliant barrier is in place, with a maximum fine of $5,000 and a $1,000 infringement notice for getting it wrong.
This lesson sits before concept design for one reason: the barrier constrains the garden far more than the garden constrains the barrier. Levels, paving, retaining, planting, the barbecue, the pot beside the pump — all of it is subordinate to clearances that do not bend. Landscapers break compliance on established pools constantly, almost always by raising a level or building something within half a metre of the fence.
If you are renovating around an existing pool, assume nothing. There can legally be four years between council inspections, so a certificate from 2023 tells you very little about today.
What a professional does at this stage
Four things, before a single line is drawn.
- Establish the pool’s age bracket. Pre-November 2001, pre-May 2016, or later. This decides which standard the barrier may comply with and which concessions exist. If you cannot date it, ask the council.
- Identify every element that forms the barrier today. Rarely just the pool fence — a boundary fence, house wall, window, retaining wall, above-ground pool side wall or shed wall can all be part of it.
- Get the last inspection result. The council provides the most recent inspection certificate on request to the owner. Find yours through the WALGA local government directory.
- Draw the exclusion envelope on the plan first. Hatch the 500 mm strip and the non-climbable zones on both sides, then design outside them. That is the whole discipline.
The trigger, and what counts
Water more than 300 mm deep — in-ground, above-ground, spa, portable, temporary, or a toddler’s wading pool. A spa bath in a bathroom is not caught, and nor is a fish pond, though a pond still drowns children. A lockable spa cover is not a barrier: when the cover is off there is no barrier at all. An empty pool needs no barrier but stays on the council register, and rain or a leaking retic solenoid refills one faster than you would think.
The non-climbable zone in plain terms
A barrier must be at least 1.2 m high measured on the outside, permanently fixed, vertical (it may lean away from the pool by up to 15 degrees but never towards it), with gaps between vertical members no more than 100 mm and no more than 100 mm between the barrier and a stable ground surface beneath it. Sand is not a stable surface. Pavers, concrete and decking are.
Building and Energy’s Rules for Pools and Spas sets out five non-climbable zones. They apply to any barrier under 1.8 m high, and always to a boundary barrier.
| Zone | Where it is | What it means on site |
|---|---|---|
| NCZ 1 | A 900 mm span anywhere on the face of the barrier | No handhold or foothold pair closer than 900 mm apart |
| NCZ 2 | A 900 mm quadrant sweeping down and away from the barrier, outside the pool area | Nothing climbable in that arc — this is the one gardens breach |
| NCZ 3 | A 900 mm quadrant from the top of the barrier, up and away | Overhanging branches, pergola beams, screen tops |
| NCZ 4 | 900 mm high by 300 mm deep on the poolside | Only required where gaps between vertical members exceed 10 mm |
| NCZ 5 | A 900 mm quadrant from the top of a boundary fence, on the poolside | Only for boundary barriers using the 1.8 m poolside option |
Two more rules that do most of the damage to garden layouts:
- Nothing within 500 mm. No object, step, retaining wall or ground level change that reduces the barrier’s required height may sit within 500 mm of it.
- Projections over 10 mm count as potential footholds unless chamfered at 60 degrees flush to the face behind. That includes gate hinges — see Industry Bulletin 123, which tells installers to space the bottom of the top hinge 900 mm clear of the top of the bottom hinge.
The garden decisions this kills
| What you wanted | Why it fails | What to do instead |
|---|---|---|
| Raised bed or low retaining wall against the fence | Level change inside 500 mm, reduces effective height | Hold the bed 600 mm off and drop the wall below fence level |
| Lifting the paving 100 mm to fix a fall | Reduces barrier height on that side | Regrade away from the barrier, or raise the fence to suit |
| Bench, pot, barbecue or filter box near the fence | Climbable object in NCZ 2 | Everything frequently used belongs outside the pool area |
| Tree with a low limb over the fence | Handhold in NCZ 3 | Choose clear-trunk species; write the pruning into maintenance |
| Trellis or screen fixed to the boundary fence | Creates footholds inside NCZ 5 | Freestanding screen set outside the zone |
| Deck stepping up towards the barrier | Level change inside 500 mm | Terminate the deck 600 mm short with a flush edge |
A pergola beside a pool has to satisfy both these rules and structures and building permits; a new wall has to satisfy retaining walls approval as well.
Planting near the barrier
Vegetation near a barrier must be maintained so it does not affect compliance. Plants that do not act as a handhold or foothold are unlikely to be treated as facilitating climbing and are typically allowed inside a non-climbable zone; plants that cannot support the weight of a young child are typically permitted within 500 mm.
As a plant list: soft, non-woody, low-forking, nothing that scrambles up the fence. Dietes, lomandra, agapanthus, low grevilleas and clumping grasses are fine. A frangipani, a lilly pilly hedge, a bougainvillea on the fence and anything with a fork at 400 mm are not. Write the pruning into your maintenance schedule — compliance is judged on inspection day, not planting day. See the Perth year.
Gates: where the failures actually are
Building and Energy states that 90 per cent of young children who drowned in WA private pools reached the water through the gate area, and gates are the most common non-compliance found by inspectors. Treat the gate as the design problem, not an afterthought.
- Opens outwards, away from the pool. Never inwards, never sliding, never into a doorway.
- Self-closes from any open position, including resting on the latch, without bouncing open.
- Self-latches, and cannot re-open without operating the latch.
- Latch release at least 1.5 m above ground on the outside — or on the poolside with a 450 mm shield, at least 150 mm below the top of the gate, and no gap over 10 mm.
- No more than 100 mm under the gate, over a stable surface. Grass under a pool gate grows and stops it closing.
- No pet doors, ever.
Keep gates out of the wind, and use a single shared footing for both posts so they cannot move independently and throw the latch out of alignment. Keeping an existing frameless glass fence? Read the gate latch warning first.
Using the boundary fence
Common in Perth, and the source of most neighbour disputes. Two options:
| Option | Requirement | Use when |
|---|---|---|
| Poolside | At least 1.8 m high on your side, with a 900 mm NCZ 5 down from the top on the poolside | Almost always — compliance stays within your control |
| Non-poolside | At least 1.2 m on the neighbour’s side, nothing within 500 mm reducing that height, NCZ 1, 2, 3 and 4 satisfied on their side | Only where the fence abuts a verge, park or public land |
The non-poolside option puts your legal compliance in your neighbour’s hands: if they lean a trailer on the fence, you are non-compliant. A barrier set back 900 mm from the boundary may be treated as an internal barrier instead, which is often the cheaper answer.
Permits, inspections and money
A building permit must be in effect before the pool is constructed or installed. Since 21 June 2024 most pool fences do not need one, unless the fence also acts as a required fall protection barrier, is masonry over 0.75 m, is non-masonry over 1.8 m, or is in cyclonic wind region C or D. From 1 July 2026 the permit fee is 0.19 per cent of the estimated value of the work certified, or 0.32 per cent uncertified, minimum $121.
The builder named on the permit lodges a BA7 notice of completion within seven days. The council must then inspect within 30 days, re-inspect within 60 days if it fails, and inspect at least every four years thereafter. Councils may charge up to $312 for the initial inspection and its re-inspections, and up to $78 a year for the periodic program — payable whether or not you are inspected that year.
One recent change matters if a supplier quotes you a standard. BCA 2025 became mandatory for new private pools on 1 May 2026 and it references AS 1926.1:2024 — but Western Australia has not adopted that edition for private pools. AS 1926.1-2012 still applies here, as modified by regulation 15B. If a quote cites the 2024 standard, the supplier is working to the wrong document.
The hazards, named
- Never take a barrier down “just for the day”. If work requires removing a panel, wall or gate, an alternative compliant barrier must restrict access for the entire period it is gone. A leaning mesh panel and a witches hat is not that.
- Electrical work near water is a licensed trade. Metal fencing, gates, handrails and light fittings within 1.25 m of the pool edge must be bonded to the main earthing system by a licensed electrical contractor. Replacing a metal pool fence is not purely a fencing job.
- Silica dust. Cutting limestone block, pavers or concrete needs on-tool water suppression and respiratory protection — see site establishment and safety.
- Excavating beside a pool shell can crack it and undermine the barrier’s footings. Both are your cost.
What this changes downstream
Your plan now carries a hatched exclusion envelope: 500 mm clear of the barrier, plus the non-climbable arcs above, below and behind it. Functional zoning and levels and grading both have to respect it.
The next lesson deals with the fence you share with the neighbour — who owns it, who pays, and what you may do to it, which is exactly the question a boundary pool barrier raises.
Checklist
- Understand the non-climbable zone and what counts as climbable
- Check gate hardware, self-closing and self-latching requirements
- Position planting and structures so they never breach the barrier
- Book the council inspection before filling

Swimming pool and spa safety barrier requirements
Building and Energy, Department of Local Government, Industry Regulation and Safety
Why this oneThe regulator's own landing page and the correct starting point for anything you build near a pool. It sets the trigger at water more than 30 cm deep, confirms that all swimming pools and spas need building approval, names AS 1926.1-2012 and AS 1926.2-2007 as the standards for barriers installed after 1 May 2016, and states that the maximum period between council inspections is four years. Every other document listed here is linked from it, including the industry bulletins that record what changed and when.

Rules for Pools and Spas: A guide to the requirements for safety barriers in Western Australia
Building and Energy, Department of Local Government, Industry Regulation and Safety
Why this oneThe single most useful document in this lesson: 48 pages, December 2025 edition, replacing the 2016 version. It reproduces the barrier requirements under licence from Standards Australia with diagrams, so you get the five non-climbable zones, the 500 mm clear rule, gate latch and hinge geometry, boundary-fence poolside and non-poolside options, retaining walls, balconies, windows and above-ground pool walls without buying AS 1926.1. Its FAQ section answers the two questions landscapers actually ask — whether you can plant near a barrier, and what happens to an empty pool.
Change this for PerthGuidance, not law. It covers the deemed-to-satisfy pathway only; a performance solution must be approved by your local government before you rely on it. Only the local government can confirm a barrier is compliant.

Rules for Pools and Spas — a simple checklist
Building and Energy, Department of Local Government, Industry Regulation and Safety
Why this oneThree pages you can print, take outside and work through against your existing barrier before you design anything. Gate first (self-closing from any position, self-latching, opens outwards, latch release at least 1.5 m up), then fence (1.2 m outside, uprights under 10 cm apart, 90 cm between handholds and footholds, under 10 cm gap to a stable surface), then climbable objects (90 cm clear outside, 30 cm clear inside). It names the culprits explicitly: barbecues, plant pots, trees, retaining walls, plumbing, toys, furniture and pool pumps.
Change this for PerthThis one-pager still carries Department of Mines, Industry Regulation and Safety branding from March 2020; the agency is now the Department of Local Government, Industry Regulation and Safety.

Non-compliant swimming pool gate latch assemblies
Building and Energy, Department of Local Government, Industry Regulation and Safety
Why this oneA live product warning about typically unbranded key-lock latch assemblies used on frameless glass pool fencing, where twisting the striker can leave the latch held open so the gate never re-latches. It is also where Building and Energy publishes the statistic that should govern your whole design: 90 per cent of young children who drowned in WA private pools got to the water through the gate area. If you are reusing an existing glass fence in a renovation, check this before you spend a dollar on anything else.

Swimming pools and spas: electrical bonding
Building and Energy, Department of Local Government, Industry Regulation and Safety
Why this oneThe page that catches landscapers out. Metal items within 1.25 metres of the pool edge — including fencing, gates, handrails, ladders and light fittings — must be bonded to the main earthing system under clause 5.6.2.6 of AS/NZS 3000:2018, and that bonding must be carried out by a licensed electrical contractor. Replacing a metal pool fence or gate as part of a garden renovation is therefore not purely a fencing job, and this is the page to hand your electrician.
