Pool fence rules in Western Australia

Every pool needs a building permit, and the 300mm test is separate

Building and Energy, the WA regulator, states that a building permit is required for all swimming pools and spas. There is no size or type exemption that gets you out of the permit, and that includes above-ground and portable pools that people often assume sit outside the system.

The barrier requirement is a different test. The Building Regulations 2012 define a private swimming pool as one that “has the capacity to contain water that is more than 300 mm deep”. Capacity is the word that matters — it is what the pool can hold, not how much water is in it on the day someone looks at it. A portable pool that can be filled past 300mm needs a compliant barrier exactly as an inground concrete pool does.

The builder carries a duty at handover: Building and Energy states the builder must provide a compliant barrier and submit a completion notice within seven days. From handover the obligation moves to you as the owner, and it does not lapse between inspections.

The standard is AS 1926.1-2012, and the 2016 date matters

WA barriers must comply with AS 1926.1-2012 (safety barriers) together with AS 1926.2-2007 incorporating amendments 1 and 2 (location of barriers). Pools installed before 1 May 2016 may instead comply with the older AS 1926.1-1993.

That date is the first thing to establish on an existing pool, because the two standards are not the same document and a barrier that was legitimately compliant in 2010 is not automatically judged against the 2012 rules. If you are buying a WA property with a pool, the age of the barrier is worth knowing before you price any rectification.

One WA-specific rule catches renovators: child-resistant doors — a door from the house serving as part of the barrier — are generally not permitted for outdoor pools unless they were approved or installed before 5 November 2001. If a WA pool is currently fenced using the back door of the house, that is the arrangement to ask about first.

The four-year cycle, and why it changes what you check when buying

Local governments must inspect the barrier of every private pool in their district, and the maximum period between inspections is four years. The cycle starts from the date compliance is achieved after a barrier is installed on a new pool or spa.

This is a genuinely different regime from the eastern states. In NSW and Queensland the certificate is produced because the property is being sold or leased, so the transaction forces the check. In WA nothing about a sale triggers an inspection, and there is no certificate for a seller to give you. If you are buying in WA, the compliance history sits with the local government, not in the contract of sale — so ask the council when the pool was last inspected and what the result was, and treat the answer as part of your due diligence rather than something the vendor will hand over.

Being between inspections is not a defence. Building and Energy reported that 2,170 private pools in WA — 1.2 per cent — were overdue for barrier inspections at 30 June 2025, with 65 per cent of reporting local governments up to date. An overdue pool is an uninspected pool, not a compliant one.

What a WA inspection costs, and why the number is different in every council

The Building Regulations 2012 include regulation 53A, headed “Charges may be imposed for inspection of barrier”. Building and Energy confirms local governments can charge the owner for the initial inspection and can charge for the operation of the periodic inspection program. The regulations do not set a state-wide amount, so the fee is a local government decision and it varies.

Two verified examples, both from the councils’ own published pages:

• City of Vincent — a $218 initial inspection fee once the City receives the completion notice (form BA7), and a $62 annual swimming pool levy added to rates thereafter.
• City of Melville — a pool inspection fee of $312.00 applying from 1 July 2025.

That is a spread of nearly $100 on the same statutory obligation, which is why we will not publish a single “WA inspection fee”. Take the figure from your own council’s current schedule of fees and charges. The one number that is not council-set is the barrier itself — fencing is priced by the metre by private installers and has nothing to do with the inspection fee.

Penalties, and exactly how far we could verify them

Building and Energy’s own guidance refers to “significant fines” without publishing an amount. WA local governments do publish amounts, and they agree with each other: the City of Vincent and the City of Melville both state that the infringement penalty for a non-compliant private pool or spa enclosure is $1,000, and Vincent adds that a fine of $5,000 can be imposed by the Magistrates Court on successful prosecution.

We tried to confirm both figures in the Building Regulations 2012 themselves at legislation.wa.gov.au. The regulation text our fetcher retrieved was truncated at the swimming pool provisions, so we could read the definitions and the headings of regulations 53 and 53A but not the penalty schedule. Treat $1,000 and $5,000 as the amounts WA local governments publish, which is a credible source, rather than as figures we have read in the regulation. If the exact statutory maximum matters to you — for example in a dispute — read Part 8 of the Building Regulations 2012 directly.

The practical point is unchanged either way. A $1,000 infringement is smaller than the cost of most rectification work, and neither figure is the real risk. The regulator's stated reason for the whole regime is that drowning remains a leading cause of accidental death for young children.

If you are getting a pool built in WA

Three things to settle before you sign anything. First, confirm the builder is holding a current registration — Building and Energy publishes a register of builders, updated daily. Second, confirm who is applying for the building permit and who is responsible for lodging the completion notice, because the seven-day duty sits with the builder and you want it in the contract rather than assumed. Third, get the barrier priced in the same quote as the pool, not as an afterthought, because the pool is not lawfully usable without one.

Compare quotes on identical scope: same shell, same barrier specification, same paving area, same handover condition. A quote that excludes fencing is not cheaper than one that includes it.
