Pool Safety Inspections in Victoria — The CIS Form 23 Explained

If you own a pool or spa in Victoria, you have legal obligations that did not exist a few years ago. Since 1 December 2019 every owner has had to register their pool or spa with their local council, and at defined intervals an inspector must certify the safety barrier and lodge a Certificate of Compliance — the Form 23. Get it wrong, and the penalties stack up fast. I am Michael Tuder, registered builder, and I inspect pool barriers across Melbourne’s western suburbs. Here is what the law requires, what we look for, and the most common reasons for non-compliance.

Quick answer: In Victoria, owners of pools and spas containing more than 300mm of water must register with their local council and have the safety barrier inspected at defined intervals. The inspector lodges a Certificate of Compliance — Form 23 — with council if the barrier passes. Common failures include incorrect gate latch height, fence height under 1.2m, climbable zones inside the barrier, gaps under the fence, and direct access from the house through non-compliant doors or windows. Penalties for non-compliance can exceed $1,800 per breach.

What the law requires

Under Victoria’s Building Regulations 2018 and Building Act 1993, every owner of a pool or spa with more than 300mm of water must:

1. Register the pool or spa with their local council
2. Identify the construction date of the barrier — the construction date determines which barrier standard applies
3. Have the barrier inspected by a registered building surveyor or registered building inspector
4. Receive a Certificate of Compliance (Form 23) if the barrier complies
5. Re-inspect on a defined cycle — typically every four years for an existing barrier

The construction date of the barrier dictates the standard:

Standards have tightened over time. A barrier built to 1993 standards is held to those standards, not to the current rules — but the inspector still needs to certify the barrier complies with what was in force at construction.

What the inspection covers

A pool safety inspection is not the same as a building inspection. The scope is narrow but specific. We check:

Fence height

The barrier must be at least 1.2 metres high measured on the outside of the fence. Some older standards permitted lower heights in defined circumstances; most current pools require 1.2m minimum, with no climbable foothold within 900mm of the top.

Climbable zone

Inside the pool area, no horizontal surface above 100mm wide may be within 300mm below the top of the barrier — that gives a child a foothold. Outside the pool area, no climbable object may be within 900mm of the barrier and 1.2m above ground level — a tree, BBQ, retaining wall, or pot plant near the fence is a common failure.

Gaps and openings

• No vertical gap larger than 100mm anywhere in the barrier
• No gap under the fence larger than 100mm at finished ground level
• No openings within the gate that could be used for access

We carry a 100mm sphere — a “go/no-go” gauge — and check every gap.

Gate

This is where most barriers fail. The gate must:

• Be self-closing from any open position (release the gate at full open and it must close and latch on its own)
• Be self-latching with the latch at least 1.5m above ground on the outside of the gate, OR with a shielded release on the inside that prevents reach-through
• Open outward — away from the pool area
• Have no gap between the gate and post that exceeds 10mm

Failed gate hardware is the most common single cause of non-compliance. Self-closing hinges wear out. Latches drift out of alignment. Children’s pool drowning fatalities are disproportionately associated with gate failure.

Direct access from the house

If the pool barrier doubles as a wall of the house, doors and windows opening into the pool area must be:

• Doors — fitted with a child-restrictive device, OR replaced with a fence between the door and pool
• Windows — restricted to a 100mm opening, OR fitted with a child-restrictive device, OR fenced

A sliding door direct to the pool with no fence between is a common failure on older Melbourne renovations.

Common compliance failures

After inspecting pools across Hoppers Crossing, Werribee, Point Cook, and the Melton corridor, the same issues come up.

1. Gate self-close failed — hinges have lost spring tension, gate does not latch from a 50mm-open position
2. Climbable zone breached outside — tree branch, garden bed, BBQ, pot, or retaining wall providing a foothold within 900mm of the fence
3. Climbable zone breached inside — pump housing, garden bed, or step within 300mm of the barrier inside
4. Fence height short — 1.1m fence on a barrier built post-2010 (was permitted under earlier standards but not the current build date)
5. Gap under the fence — bedding eroded, or built over a sloped surface that creates a >100mm gap at the low point
6. Direct house access — doors and windows that need restrictors and do not have them
7. Latch on outside fitted at hand height — common on older retrofits, not compliant
8. Gate opens inward — built incorrectly, never inspected, now needs a hinge change
9. Spa cover certified as the barrier — only certain locking spa covers count, and many used today are not compliant as a primary barrier

Penalties for non-compliance

Under Victorian law, penalties for failing to register and certify a pool barrier include:

• Fines for non-registration — over $1,800 per offence
• Fines for failing to lodge a compliance certificate — significant per-day penalties for ongoing breach
• Personal liability if a drowning occurs in a non-compliant pool

Non-compliance is not just a paperwork issue. The legal and financial consequences for an owner are real. The moral consequences if a child drowns are absolute.

The inspection process

Star Building Inspections runs a defined process:

1. Confirm pool registration with council — if not registered, the owner registers first
2. Identify the barrier construction date to determine the applicable standard
3. Site inspection — typically 30–60 minutes
4. Defect list issued same day if non-compliances are found
5. Owner rectifies the issues
6. Re-inspection confirms compliance
7. Form 23 (Certificate of Compliance) lodged with council by the inspector
8. Owner receives a copy for records

Most failures are fixed within a week — gate hinge replacement, climbable item moved, gap repaired. Major failures (fence too short, door restrictors needed) take longer.

When inspection is triggered

The cycle in Victoria for an existing certified barrier is generally every four years. A new barrier triggers inspection on completion. Sale of the property does not automatically trigger an inspection — but it is common for buyers to request a current Form 23 as a condition of sale, and many vendors arrange one as part of pre-sale presentation.

If you are buying a property with a pool and the vendor cannot produce a current Form 23, the pool barrier becomes your responsibility post-settlement. That is worth a conversation before contract signing.

Frequently asked questions

Does my spa need a barrier?
If the spa contains more than 300mm of water and is not fitted with a compliant locking lid, yes. Many freestanding portable spas do qualify for the locking-lid exemption. We can confirm against the model and standard.

Can I do my own inspection and lodge the form myself?
No. Form 23 must be lodged by a registered building surveyor or registered building inspector. Owners cannot self-certify.

What if my fence does not meet today’s standards but was compliant when built?
The inspection assesses against the standard in force at the time of construction of the barrier. A barrier built in 2005 is assessed against AS 1926.1–1993 (with amendments), not the 2012 standard. If the owner has substantially altered the barrier, the date of alteration may shift the applicable standard.

Do I need to inspect every four years even if nothing has changed?
Yes. The four-year cycle is set by regulation, not by changes to the barrier. Things wear out — hinges, latches, fence panels, gate alignment — and the cycle catches that.

How much does a pool safety inspection cost?
Typically $250–$500 for a standard residential pool, depending on size and complexity. Re-inspection after rectification is usually included or a small additional fee.

Do you inspect pools in Werribee, Point Cook, and Hoppers Crossing?
Yes — across all of Melbourne’s western suburbs. Inspections, defect lists, re-inspection, and Form 23 lodgement.
