The approval a pool or spa needs turns on its size, whether it is fixed in place, and its position on the block. NSW offers three paths: exempt development, a complying development certificate (CDC), or a development application (DA). Whichever applies, the barrier and registration rules apply to almost every pool.
Exempt: small portable pools and spas
Under the Codes SEPP, some portable pools and spas need no planning approval. Broadly, the pool or spa must:
- be for residential use and sit in the rear yard
- keep 1 m or more clear of every lot boundary
- hold no more than 2,000 litres
- need no structural work and not affect the stability of other buildings
- have a barrier that keeps young children out, as required under NSW pool safety law
A spa that holds more than 2,000 litres, or one that needs structural work to install, falls outside these exempt rules. Exempt doesn't mean rule free. Once a portable pool is deep enough to hold over 30 cm of water, it needs a proper barrier and has to be registered. For more on this path, see our guide to Exempt development: small building jobs that need no approval.
CDC: in-ground pools that fit the Housing Code
Most in-ground pools in a back yard can go through the Housing Code as complying development, provided they meet its standards. The main ones are:
- the pool serves a dwelling house and is used privately
- it sits behind the house's building line
- the water line keeps 1 m or more clear of the side boundaries and the rear boundary
- coping and decking stay within the height limits the code sets
- pump noise is controlled, usually with an acoustic enclosure
Lots affected by bush fire or flooding can still use this path, subject to extra clauses, but some land is excluded, including many heritage conservation areas. During May 2026, NSW sought feedback on changes for corner lots, rural zones and dual occupancies. Those were still proposals when this article was written, so check the current code before relying on them.
DA: when the pool doesn't fit
A DA is needed when the pool falls outside the CDC standards. Typical reasons include a pool forward of the house's building line, a water line closer than a metre to a boundary, a raised pool with high coping, or land excluded from complying development. Not sure which path applies? Start with the planning certificate for the property. It shows heritage status, bush fire and flood mapping, and other constraints that can rule complying development out. Council assesses a DA on its merits. After consent, a construction certificate is needed before building starts.
What every new pool needs
- A barrier built to the current child-resistant standard, plus a CPR sign.
- An entry on the State's Swimming Pool Register.
- A BASIX certificate for larger pools, from 40,000 litres up.
- Two critical stage inspections: before reinforced concrete is poured, and once the barrier is up but before any water goes in.
- An occupation certificate when the job is complete.
Where we come in
CertifiBuild certifies new pools and spas as Class 10 work. We can check your plans against the Housing Code in a plan assessment, issue the CDC where the design complies, act as principal certifier and handle each inspection. Read about our pool and spa certification, or request a quote.
Local help across NSW
CertifiBuild certifies Class 1 and Class 10 work in 39 council areas. Local rules on these council pages are a good place to start: City of Newcastle, City of Ryde, City of Parramatta, Shellharbour City Council, Georges River Council, City of Sydney.
Suburb pages with local planning notes: North Lambton, North Ryde, Northmead, Oak Flats, Oatley, Paddington, Palm Beach, Panania, Peakhurst, Penrith. You can also browse every service area.
