When does a pool permit expire?

Victoria's six months is the deadline nobody diarises

Most people building a pool know roughly how long they have to get started. Almost nobody knows how long they have to finish, and in Victoria that is the tighter of the two numbers by a distance.

Regulations 53 and 54 of the Building Regulations 2018 set both. Building work involving a pool, spa and associated safety barrier must commence within 12 months of the date the building permit issues, and must be completed within six months after the building work commences.

Six months is a comfortable window for a build that goes well. A concrete pool runs a few months of actual construction with cure and cure-dependent trades in between. But it is not a comfortable window for one that hits a wet winter, a supply delay on coping or glass, a subcontractor who does not turn up, or a builder quietly winding down. The gap between “this is taking longer than we hoped” and “the permit has expired” is narrower than people assume, and nothing rings a bell when it closes.

There is one relief valve. Where the pool, spa and barrier are being carried out on an allotment concurrently with other building work on the same allotment, they can be completed within the time limits for that other work, under regulation 54(c). A pool going in as part of a house build inherits the house's timeline. A pool going into a finished backyard does not.

What lapsing actually costs in Victoria

This is the part that turns a paperwork problem into a money problem. Where the pool and the safety barrier have not been completed, a new building permit and a new building permit levy are required before any building work continues on the site. A stop work order should be issued where the builder continues working without one.

So the cost of an expired permit is not a fine. It is the permit again, the levy again, and the surveyor's fee again — on a job that is already behind and, if the permit expired because the builder stopped, on a job whose builder may not be paying for anything.

There is a further consequence that is not financial. If the surveyor determines that the incomplete work will be a danger to young children entering the pool area, and considers that an emergency order should issue, they contact the municipal building surveyor. A half-finished pool is an open excavation, and an open excavation that holds 300mm of water — rain is enough — needs a complying AS1926.1-2012 barrier regardless of whose fault the delay is.

That combination is why an unfinished Victorian pool is urgent in a way an unfinished bathroom is not. What to do when a pool build stops works through the order to deal with it in.

Queensland: two years, and the extension has to be early

Queensland's clock is set by section 85 of the Planning Act 2016, which deals with the lapsing of an approval at the end of its currency period. Where no period is stated, a building development approval has a default currency period of 2 years after the approval takes effect, and the development must substantially start within it.

Two things make Queensland easier than Victoria and one makes it harder. Easier: two years to start rather than one, and the currency period is about starting, not finishing. Harder: an extension under section 86 must be applied for before the lapsing date. Once an approval has lapsed there is nothing left to extend and the process starts again.

Queensland's genuinely tight deadline sits elsewhere. Under the Queensland Home Warranty Scheme, a non-completion claim requires the contract to have ended within 2 years after the day work starts, and the claim must be made within 3 months after the day the contract ends. Those are the clocks that decide whether an abandoned pool is recoverable, and they run independently of the approval.

New South Wales: five years, and what does not count as starting

NSW is the most generous on paper. A development consent lapses five years after the date it starts to operate, under Division 4.9 of the Environmental Planning and Assessment Act 1979. The consent does not lapse if building, engineering or construction work related to it is physically commenced on the land before that date.

The trap is in the definition. Under clause 96 of the Environmental Planning and Assessment Regulation 2021, work is not physically commenced merely by creating a bore hole for soil testing, removing water or soil for testing, or carrying out survey work including placing pegs or other survey equipment.

That list reads like the first things that happen on a pool job. A geotechnical bore and a set of survey pegs feel like the build starting, and for the purpose of keeping the consent alive they are not. The definition applies to consents granted on or after 15 May 2020, so it covers every current pool approval.

If your NSW consent is approaching five years, the question to ask your builder is not “have we started” but “what physical building, engineering or construction work has been done on the land”. Whether you need council approval at all is worth checking first — some pools go through complying development instead.

The three dates worth writing down on day one

None of this needs a diary system. It needs three dates on the fridge, taken from the permit or consent the day it arrives:

1. The date the approval was issued or started to operate. Every other date is calculated from it.
2. The last date to start — 12 months in Victoria, 2 years in Queensland, 5 years in NSW.
3. The last date to finish, which only Victoria sets, and only once work has actually commenced. Ask your surveyor to confirm the commencement date they have recorded, because your six months runs from theirs, not from when the first truck arrived.

If a build is drifting toward any of them, the moment to act is before the date, not after. In Queensland an extension must be applied for before lapsing; in Victoria a lapsed permit means a new levy; in NSW a lapsed consent cannot be revived. All three reward acting a month early and punish acting a week late.

If the reason for the drift is that you are waiting on a builder who has gone quiet, the approval clock is a second problem and it is worth getting comparison quotes for finishing the work while the permit is still alive — a replacement builder inherits a valid permit far more easily than an expired one.
