Plunge pool rules in NSW
Last checked 5 Nov 2026 against the NSW legislation and official pages listed at the end.
Most plunge pools in NSW need approval. Only a portable pool of 2,000 L or less in the rear yard is exempt. Anything bigger needs a complying development certificate (CDC) from your council or a registered certifier, or a development application (DA). A CDC needs the pool behind the house and its water line at least 1 m from the side and rear boundaries.
The three approval routes
| Route | When it applies | Who approves |
|---|---|---|
| Exempt | Portable pool or spa of 2,000 L or less, in the rear yard, at least 1 m from every boundary, no structural work to install | No approval, but it still needs a barrier and registration |
| CDC | Bigger pools that meet every Housing Code pool standard (cl 3.28) | Your council or a registered certifier, usually faster than a DA |
| DA | Anything that misses a CDC standard, a heritage item, or a pool in front of the house | Your council |
The Housing Code standards for a CDC
A pool can get a CDC only if it meets all of these (Codes SEPP 2008, Housing Code cl 3.28 and 3.30):
- For private use and associated with a dwelling house cl 3.28(1)
- If the lot isn't on a sewer main, pool water discharge needs a Local Government Act approval cl 3.28(2)
- Pump in a soundproofed enclosure, more than 450 mm from each lot boundary cl 3.28(3)
- Coping no more than 1.4 m above existing ground, and no more than 300 mm wide if it's over 600 mm high cl 3.28(4)
- Decking no more than 600 mm above existing ground cl 3.28(5)
- Behind the building line of the house (not in the front yard) cl 3.28(6)
- Water line at least 1 m from a side or rear boundary cl 3.28(7)
- On a corner block, set back from the secondary road at least as far as the house cl 3.28(7A)
- In a heritage conservation area: behind the building line, next to the rear boundary, and no closer to each side boundary than the house cl 3.28(8)
- Excavation limits for pools are set out in cl 3.30 cl 3.30
When it has to be a DA
- Heritage item or draft heritage item: DA
- In front of the building line: DA
- Any standard above not met: DA
Bushfire-prone land and flood-affected lots: whether a CDC is possible depends on the site, so ask a certifier before you buy a pool. We haven't confirmed the exact limits yet, so we don't state them here.
Fencing: every plunge pool needs a barrier
Every pool or spa that can be filled to more than 300 mm deep needs a child-resistant barrier, plunge pools and portable pools included. A pool fence must be at least 1.2 m high, measured from finished ground level. Some spas can use a lockable child-resistant lid instead, but not spas used for swimming or plunge pool spas.
Registering your pool
Every pool and spa in NSW must be on the NSW Swimming Pool Register, against the property's address. Registering online is free, and it doesn't mean the pool complies. If you sell or lease, you'll also need a pool compliance certificate.
Common questions
Do I need council approval for a plunge pool in NSW?
Almost always. Only a portable pool of 2,000 L or less is exempt, and nearly every plunge pool holds more. You need a CDC from your council or a registered certifier if the pool meets the Housing Code standards, or a DA from your council if it doesn't.
Does an above-ground plunge pool need approval?
Yes, if it holds more than 2,000 L, which almost all do. Being above ground doesn't make it exempt. See the above-ground rules.
How close to the boundary can a plunge pool be?
For a CDC, the water line must be at least 1 m from each side and rear boundary, and the pump must sit in a soundproofed enclosure more than 450 mm from each boundary. Closer than that needs a DA.
Can I put a plunge pool in my front yard?
Not under a CDC. A pool must be behind the building line of the house for a CDC, so a front-yard pool needs a DA from your council.
Does a plunge pool need a fence?
Yes. Any pool that can be filled more than 300 mm deep needs a child-resistant barrier at least 1.2 m high, plunge pools and portable pools included.
