Can my garage or shed be part of the pool fence?

The permanent structure test, and why a bolt fails it

Everything on this page comes back to one definition. AS1926.1-2012 requires that a barrier be a permanent structure, and it defines that as “a barrier or part of a barrier which cannot be removed without the use of tools”.

Apply that test and the roller door answer follows. An automatic roller door opens with a button. A manually bolted roller door opens by sliding a bolt. Neither requires a tool, so neither is a permanent structure, so neither is part of a compliant barrier.

The Victorian Building Authority goes further and states the human reason rather than just the technical one: the use of automatic closing roller doors, or manual slide bolting of roller doors in the closed position, are “not appropriate solutions for compliance with AS1926.1” because “the temptation for owners to 'unbolt' the roller door is too great and is an unacceptable risk”.

That sentence is unusually candid for a technical document, and it is the key to the whole area. The standard is not assessing whether a barrier can be made safe. It is assessing whether it will still be safe on the two hundredth hot afternoon when someone wants to get the mower out. A bolt that a reasonable adult will slide open is treated as a bolt that will be open.

The door can still be part of the barrier as a panel. It needs to be permanently fixed in the closed position with fasteners that can only be removed using a tool such as a screwdriver, spanner or drill. At which point it is a wall with a door-shaped past, and the garage is accessed another way.

Why the side-hung garage door is the one people get wrong

The roller door rule is at least intuitive. The side-hung door rule is the one that surprises people mid-quote, because it looks like the safe option.

A side-hung door that would typically allow access to the garage from the yard cannot be used as part of the barrier. A separate barrier must be installed around the garage or shed door.

This applies even though the door is self-closing in your head. The rule for outdoor pools does not turn on the door's hardware — it turns on the fact that it is a door to an outdoor pool area at all. Under clause 2.7 of AS1926.1-2012, child-resistant doorsets can only be installed for access to indoor pools and the indoor part of an indoor/outdoor pool. There is no outdoor version of that permission.

The same logic rules out the house door. All outdoor pools and spas built after 1 May 2010 must not have direct access to the pool area via a door from a building, house or garage. Where such a door exists, it must be removed and replaced with a child-resistant window, or altered to render it un-openable — all door furniture removed and the door screwed, bolted or fixed to the frame with fixings that cannot be removed, using non-removable screws or lockable nuts.

Walls, though, remain available, and that is the useful half of the rule. Walls of buildings and child-resistant windows can still be used as part of the barrier. The cost-saving idea is not dead; it just cannot include the opening.

What a pool area is, and why it is not your backyard

There is a bigger design assumption underneath all of this, and getting it wrong is expensive because it is discovered at the design stage or at final inspection.

AS1926.1-2012 defines the pool area as “the area that contains the pool and is enclosed by a barrier”. The VBA draws the conclusion explicitly: the whole allotment cannot be a pool area. The pool area must be a separate, defined area on the allotment, and access to it must not be available directly from any other building, including the dwelling and any outbuilding.

So the plan where the existing boundary fence plus the house walls enclose the yard, and the yard is the pool area, does not work. There has to be a barrier between the buildings and the pool.

A boundary fence can be part of the barrier where it does the job: it must be 1800mm or greater above finished ground level on the inside, with a non-climbable zone measured 900mm down from the top of the inside face. The outside can be climbable, which is sensible — the inside NCZ is the one you can actually maintain. Non-climbable zones explained covers the geometry.

Sheds, gazebos and pool houses inside the barrier

The rules for structures within the pool area are about supervision and about propping gates open, and they split cleanly.

Keep enclosed non-habitable buildings out. Tool sheds, garages, barbeques and enclosed non-habitable buildings should be located outside the pool area, for a reason that is entirely about human behaviour: it reduces the likelihood of self-closing gates being propped open to get into them. The second reason is that a child may be hidden by or within a structure, reducing the ability to supervise the pool area.

Habitable rooms must be separated. Enclosed buildings or structures in the pool area containing kitchens, playrooms, change rooms or entertainment rooms that open directly into the pool area are habitable rooms forming part of the main building, and must be separated from the pool area with a barrier. A cabana with a kitchen in it is a building, not furniture.

Open structures are fine. An open-sided gazebo or other open shade structure supported by posts only is not considered to substantially reduce visibility within the pool, and may be constructed wholly or partly within the pool area without being separated by a barrier.

The test running through all three is visibility and temptation. If it blocks the view of the water, or gives someone a reason to prop the gate, it belongs outside the barrier. Budgeting for the barrier you actually need is easier before the design is locked: what a pool fence costs sets the ranges, and comparing quotes will show quickly whether a builder has priced a barrier around the garage door or quietly assumed the door counts.

The above-ground exception, and its 300mm rule

One structure genuinely can do double duty. The wall of an above-ground pool can form part of a pool barrier, provided the walls are a minimum of 1.2m high above finished ground level and are non-climbable.

But it does not remove the need for a barrier entirely. An above-ground pool still requires a safety barrier to protect the ladder access, the pump and the filter, and that barrier must be 300mm clear of any part of the ladder, pump, filter or any other climbable object.

That 300mm figure is easy to lose on a small site, because the pump and filter are usually installed tight against the pool wall to keep the pipe runs short. A barrier that has to stand 300mm off them takes more space than people allow for. Permits for above-ground pools covers the approval side, and above-ground versus in-ground covers the choice itself.
