Spa Fence Regulations Victoria
This is the article we wish more spa owners read sooner.
The short version: under the Victorian Building Regulations 2018, any spa or hot tub with water depth over 300mm is treated the same as a swimming pool. Same compliance obligation. Same barrier requirements under AS1926.1. Same Form 23 lodgement with council. Same four-year re-certification cycle.
That comes as a surprise to many spa-only owners. Plenty of properties with a single in-ground or above-ground spa have never been certified, never been registered, and have no idea they should be. If that's you, you're not alone — and the path back to compliant is straightforward.
The practical side, as ever: we inspect the barrier, take care of minor repairs where needed, supply your Form 23 Certificate of Pool Barrier Compliance, and lodge it with your council for you. Simple and stress-free.

The 300mm rule applies to spas too
The 300mm water-depth threshold is the deciding factor. If the spa or hot tub holds water deeper than 300mm at any point, the barrier obligation applies. That covers:
- In-ground spas of any size.
- Above-ground spas and hot tubs with internal depth over 300mm — which is essentially all permanent residential spas.
- Inflatable spas left in place with water in them.
- Plunge pools and small "splash" pools that double as spas.
What's not required: portable spas that are filled, used, and emptied each time, with no permanent installation and no standing water. In practice, almost no residential spa qualifies as truly portable in this sense.
The "but it has a hard cover" question
We get this all the time. "Surely my spa is fine — it has a lockable lid on it."
The short answer is no. A lockable spa cover doesn't satisfy the barrier requirement on its own. The regulations require a barrier — a fence, a wall, or an equivalent isolating enclosure — meeting the AS1926.1 standard. A cover is a supplementary safety device, not a substitute for a barrier.
Some councils may take a slightly different view in marginal cases, but the conservative reading — and the only one that holds up under inspection — is that a hard cover is not a compliant barrier. If your spa is otherwise isolated by the house and a child-proof structure, that's a different (and case-specific) conversation.
If you want a clear yes/no on your specific spa setup, a $99 + GST FaceTime consultation is the cheapest way to get it.
Barrier options for spa-only properties
For a spa without a pool, you have three practical compliant options:
1. Dedicated spa barrier. A fence built specifically around the spa, meeting the 1,200mm height, 100mm gap, 900mm NCZ, self-close/self-latch gate rules. Common where the spa sits on a deck or patio.
2. Pool-area-style enclosure. A larger fenced enclosure that contains the spa within the broader backyard area, isolating the spa from house access. Usually the cleanest option when the spa is on lawn or paving without an existing structure.
3. House-as-barrier (in very specific cases). Where the spa is on a balcony, courtyard or enclosed area, the building structure itself can sometimes form part of the barrier — but every opening (doors, windows) into that area must meet the same compliance rules as a pool gate or fence. This is the path that requires the most care to get right.
We'll talk you through which option fits your setup at the inspection. For any new barrier construction, we coordinate the right trade on your behalf and re-inspect at no extra charge once it's done.
"I didn't know — am I in trouble?"
A lot of spa-only owners come to us having only recently realised the obligation applies to them. Common scenarios:
- Bought a property with an existing spa, no documentation in the file.
- Installed a spa themselves years ago without a permit conversation.
- Inherited a property where the previous owner certified the pool but a separate spa was never assessed.
- Replaced an old spa with a new one and assumed the existing certification carried over.
The reassuring bit: most of these are quick to bring into compliance. Council notices for spa-only properties are relatively uncommon — but if you're selling, renting out, or just want peace of mind, getting the certification done now is much cheaper and calmer than dealing with it under deadline.

What an inspection looks like for a spa
The inspection process is the same as for a pool — and the cost is the same.
- 45 to 90 minutes on-site.
- VBA-registered inspector checks the barrier against the applicable AS1926.1 standard.
- Plain-language verdict on the day.
- Certificate of Pool Barrier Compliance issued same-day where compliant.
- Form 23 lodged with your council within 1–2 business days.
- Re-certification reminder set for ~3 months before your next four-year mark.
For spa-specific configurations — built-in seating around the spa, decking that doubles as access, courtyard installations — we'll talk through the specifics on the day.
Frequently asked questions
Do spas really need a compliance certificate in Victoria? Yes — any spa or hot tub with water depth over 300mm is treated the same as a pool under the regulations.
Does my spa cover count as a barrier? No. A cover is a supplementary safety device, not a compliant barrier under AS1926.1.
My spa is inside the house — do I still need a certificate? Possibly. If the spa is isolated by the building structure and every opening into the spa area meets pool-gate standards, the house itself can sometimes form part of the barrier — but it's a case-by-case assessment.
What about a portable spa I fill up and empty each time? A genuinely portable spa with no standing water doesn't trigger the barrier obligation. In practice, almost no permanent residential spa qualifies.
How much does a spa inspection cost in Victoria? A full inspection with Form 23 lodgement is $299 + GST — same as a pool.
How often does a spa need re-certification? Every four years.
My spa is just outside the back door. Does the door need to comply? If the door opens into the spa enclosure and there's no other barrier between, yes — the door must meet self-closing, self-latching, latch-height requirements.
Do you cover regional Victoria for spa inspections? Yes — we travel to regional and rural Victoria regularly.
