The four mandatory pool inspection stages in Victoria
A Victorian pool is not inspected once at the end. Regulation 169 sets four mandatory notification stages across the build, and the relevant building surveyor has no power to skip one. A complying barrier is required as soon as the excavation holds 300mm of water, and the site fence must be up before any digging starts. A fibreglass pool and a concrete pool pass the same four stages in a different order.
Victoria prescribes four mandatory notification stages under regulation 169: completion of the excavation; before pouring any footing or in-situ reinforced concrete member specified in the permit; completion of any regulation 116 precautions; and final, on completion of the pool and its barrier. The surveyor cannot vary or omit any of them, and a complying barrier is required once the hole holds 300mm of water.
The short answer
- Four stages, set by regulation 169 of the Building Regulations 2018. The relevant building surveyor has no discretion to drop one.
- A site fence must be in place before any excavation commences — that is before stage one, not at it.
- A complying AS1926.1-2012 barrier is required as soon as the excavation or shell holds 300mm of water. Rain counts.
- A concrete pool and a fibreglass pool hit the same four stages in a different order, because the fibreglass shell is filled with water during construction.
- A concrete pool must not be filled until the surveyor has certified a complying barrier is in place.
| Stage | What triggers it | Concrete pool | Fibreglass pool |
|---|---|---|---|
| Before stage 1 | Site fence in place | Before excavation commences | Before excavation commences |
| 1 | Completion of any excavation for the pool or spa | Inspection 1: excavation complete, precaution measures erected | Inspection 1: excavation complete, precaution measures erected |
| 2 | Before pouring any footing or in-situ reinforced concrete member specified in the permit | Inspection 2: after steel fixing, before the shell is poured | Not applicable unless the permit specifies a member |
| 2 (fibreglass) | Shell installed and filled | — | Inspection 2: shell installed, water in, complying barrier erected |
| 3 | Completion of any regulation 116 precautions | Inspected with the above where precautions were required | Inspected with the above where precautions were required |
| 4 | Final, on completion of the pool, spa and related safety barrier | Inspection 3: final barrier. No water in the pool yet | Inspection 3: final barrier |
| Can the surveyor omit it? | — | No | No |
The four stages, and the one word that matters in each
Regulation 169 of the Building Regulations 2018 prescribes the mandatory notification stages for the construction of a swimming pool or spa. There are four:
- The completion of any excavation related to the installation of the pool or spa.
- Before pouring any footing or in-situ reinforced concrete member that is specified in the relevant building permit by the surveyor.
- The completion of any precautions required under regulation 116, which exist to protect the safety of the public.
- Final, on completion of the pool or spa and the related safety barrier.
The sentence that gives this page its point comes straight after that list in the state's own practice note: “The Regulations do not provide for an RBS to vary or omit any of the above mandatory notification stages.” Your building surveyor is not being difficult when they will not sign something off early. They have no power to.
Three qualifications are built in and are not discretion in the loose sense. Stage 2 only bites where the surveyor has specified a footing or concrete member in the permit. Stage 3 does not arise if no precautions were required under regulation 116. And depending on the pool type, stages can fall close enough together that one site visit inspects several — which is an efficiency, not an omission.
The step before step one: a site fence, before you dig
The first obligation is not an inspection at all, and it is the one most often discovered late. In Victoria a site fence must be in place before any excavation for the pool or spa commences.
Regulation 116(3) requires that any excavation be fenced or otherwise guarded against being a danger to life or property, and regulation 116(1) requires the surveyor to turn their mind to protection of the public during construction. The permit application should set out how the excavation will be fenced, and the surveyor considers the height of the barrier, whether there are footholds or handholds that could help a child climb it, the spacing of horizontal and vertical members, and what loads could be placed on it.
A site fence or hoarding must be provided between an existing dwelling and the pool construction area. If the pool is going in at the same time as the house, an additional site fence is required. Where a gate is fitted, the practice note recommends it comply with AS1926.1-2012; where there is no gate, the barrier stays in place except when access is needed and people are present the whole time it is open.
This is a real cost line and it belongs in the quote. If your quotes differ by a few thousand dollars, temporary fencing is one of the things to check is in both. Our guide to what differs between pool quotes covers the usual omissions, and comparing several quotes is the fastest way to see which one has left it out.
300mm of water, including rain
The rule that surprises people is not about the finished pool. As soon as the excavation, the pool or the structure contains more than 300mm of water, a safety barrier complying with AS1926.1-2012 must be erected and maintained.
Nothing in that says the water has to be deliberate. A hole in the ground after a wet week is a hole in the ground holding 300mm of water, and the obligation attaches. Victorian excavations sit open for days between stages, and this is the single most common way a compliant site becomes a non-compliant one without anybody doing anything.
It is also why the two pool types run differently. A fibreglass shell is placed in the excavation and filled with water as part of the installation, to hold it down and true. So the barrier obligation arrives in the middle of the build: the practice note requires a complying barrier in place immediately after the pool is filled. A concrete pool has no water in it until the end, and the rule runs the other way — the pool must not be filled until the surveyor has certified that a complying barrier exists.
Where the surveyor determines a complying barrier is needed for the excavation itself, it can be installed and inspected as soon as the excavation is finished, which collapses two obligations into one and is usually the cheaper path.
What happens if a precaution is moved
Site safety has to be maintained through the build, not just established at the start. If the surveyor becomes aware that a precaution measure has been moved or altered so that it no longer complies with the permit, they issue a direction to fix under sections 37A to 37F of the Building Act 1993.
It goes to the builder or the person in charge of the site — not to you — and it can be given orally or in writing. If given orally and the work is not rectified within 7 days, the surveyor must issue a written direction in the approved form. A direction to fix must be issued before any building notice or building order.
As an owner, the useful thing to know is that the escalation ladder starts quietly and has a documented first rung. How a direction to fix works sets out the whole sequence.
If the pool is not finished, the permit is the problem
The final stage is the one with a deadline attached, and missing it is expensive in a way that has nothing to do with safety.
Where the pool and its safety barrier have not been completed, a new building permit and a new building permit levy are required before any building work continues, and a stop work order should issue if the builder keeps going without one. Regulations 53 and 54 give the underlying clock: pool work must commence within 12 months of the permit's issue date and be completed within six months after commencement.
Six months is not long for a build that hits weather, a supply delay or a quiet contractor. If the work stalls, the permit expiring is a second problem stacking on top of the first, and it does not announce itself. Permit expiry and lapsed permits covers the arithmetic, and what to do when a build stops covers the rest.
