Pool Approval Time in Parramatta: CDC, DA and Sydney Water

Name: comparepoolquotes
Price range: $$$

A pool that qualifies as complying development in Parramatta can be approved in about 10 days: the NSW Regulation gives the certifier 10 days to decide a pool-only CDC. A development application takes far longer. City of Parramatta averaged 92 assessment days in the state's August 2026 snapshot, after 12 days to lodge.

The short answer

CDC: 10 days to decide. Section 133 of the EP&A Regulation 2021 sets 10 days, or 20 days where the CDC is for a new dwelling or an addition and neighbours must first get 14 days' notice.
DA: 40 days on paper, 68–92 days in practice. A DA is deemed refused after 40 days (60 for integrated or concurrence DAs). Parramatta's average assessment time ran 68–87 days across the 2025–26 monthly snapshots and 92 days in August 2026.
Lodgement is its own queue. Parramatta took 26–37 days on average to lodge a submitted DA in 2025–26, against a state expectation of 7 days. The August 2026 snapshot shows 12.
Sydney Water comes first on both routes. If the pool doesn't affect its pipes, the building plan approval is issued online straight away for $24.15. If it does, an ‘out of scope’ review generally takes up to 42 days.
The slowest stage is DA assessment. A design that keeps the pool inside the CDC standards skips it entirely.

The Parramatta approval clock table: each stage, the CDC route against the DA route (read 30 September 2026)
Stage	CDC route	DA route	What sets the time
1. Sydney Water building plan approval	Online and immediate if no impact on its assets; $24.15	Same; council will not grant consent without it	Sydney Water: a water servicing coordinator sets the time if there is an impact; an ‘out of scope’ review is generally up to 42 days
2. Submission to lodgement	Not separately measured	Parramatta: 26–37 days average in 2025–26 snapshots; 12 days in August 2026	NSW council league table; state expectation 7 days
3. Legal decision period	10 days (pool only); 20 days if the CDC also covers a new dwelling or addition	Deemed refusal after 40 days; 60 days for integrated, concurrence or designated DAs	EP&A Regulation 2021, ss 91 and 133
4. What Parramatta actually averages	No council average published for CDCs	68–87 days (2025–26 snapshots); 92 days (August 2026)	NSW council league table; all DA types, not pools only
5. State expectation for 2026–27	—	Average of 95 days from lodgement, or the council's own previous-year average if lower	Statement of Expectations Order 2024
6. Neighbour notice	14 days before approval only if the CDC is for a new dwelling or addition; 7 days before work starts where the CDC is for a new building	Not set by these sections	EP&A Regulation 2021, ss 134 and 148
7. After approval	The CDC is the construction approval	A construction certificate is still needed; no statutory period found	Varies with the certifier

How long does it take to get a pool approved in Parramatta?

It depends almost entirely on which route your pool takes, and the two routes differ by months, not days. The route is decided by the block and the design, which our Parramatta pool cost and approval-route guide sets out: heritage items, uncertified flood-affected land and lots within 40m of the river or a creek are the usual reasons a Parramatta pool needs a DA. This page is only about the time each route takes.

Worked example, CDC route. Sydney Water approval issued online the same day (no impact on its pipes). The certifier then has 10 days to decide. If the certificate carries the pre-construction notice condition, add 7 days before work starts. That is about 17 days from a complete application to a start date.

Worked example, DA route, using City of Parramatta's own averages. August 2026 snapshot: 12 days to lodge + 92 days to assess = 104 days, about 15 weeks, before the construction certificate. Using the range across the 2025–26 monthly snapshots instead: 26–37 days to lodge + 68–87 days to assess = 94–124 days. These are Parramatta's averages for all development applications, not for pools, and the state does not publish a pool-only figure.

The quotable version: in Parramatta, a pool that fits the CDC standards is a matter of weeks, and a pool that needs a DA has averaged three months or more before building approval.

The CDC clock: 10 days, and when it becomes 20

Section 133 of the Environmental Planning and Assessment Regulation 2021 says a CDC must be determined within 20 days if section 134 applies, and 10 days otherwise. Section 134 applies to a CDC that involves a new dwelling or an addition to an existing dwelling, on a lot within 20 metres of another lot with a dwelling on it. In that case the certifier cannot issue the certificate until at least 14 days after writing to the neighbours.

A pool on its own is neither a new dwelling nor an addition to one, so on our reading of the Regulation a pool-only CDC sits on the 10-day clock with no pre-approval notice. A pool bundled into a CDC for a new house or an extension takes the 20-day clock. The NSW Government's general line, ‘as little as 20 days’, describes the longer case.

The other notice is the one before work starts. Section 148 requires CDCs for a new building, an addition or a demolition to carry a condition that neighbours within 20 metres get written notice before work starts. In the City of Parramatta, one of the council areas listed as ‘relevant land’, that is at least 7 days; elsewhere it is 2. Ask your certifier whether that condition is on your certificate, and put the date in the builder's programme.

The pool-specific CDC standards (private use, behind the building line, waterline at least 1m from side and rear boundaries) are on the NSW Planning Portal. If a design misses one by 200mm, redesigning is usually faster than a DA.

The DA clock: why 40 days turns into three months

The Regulation's 40 days is a deemed refusal period, not a promise. Section 91 says a council is taken to have refused a DA it has not decided within 40 days (60 for designated, integrated, concurrence and some biodiversity applications). That gives you a right to appeal. It does not make the council decide.

What Parramatta actually takes is now published. The NSW Government's council league table captures each council's average lodgement and assessment days every month. City of Parramatta's figures:

2025–26 monthly snapshots: 26 to 37 days average to lodge, 68 to 87 days average to assess.
August 2026 snapshot (captured 8 September 2026): 12 days to lodge, 92 days to assess.

For comparison, the state's expectation for 2026–27 is an average of 95 days from lodgement, or the council's own previous-year average if that is lower, and 7 days from submission to lodgement. The expectation is the lower of those two numbers. Parramatta's August 2026 figure of 92 days is under 95, but above every one of its 2025–26 monthly figures (68–87), so whether it meets its own benchmark depends on how the state computes the council's previous-year average. Its 2025–26 lodgement averages were several times the 7-day expectation.

The quotable version: Parramatta's DA assessment averages ran at roughly double the 40-day deemed-refusal period through 2025–26. Plan the build start from the average, not from the statute. The state-wide picture, and the Queensland equivalent, is on how long council approval takes for a pool.

What makes a Parramatta pool approval slip

The slowest stage is DA assessment, and three things stretch it.

1. A request for more information. Under section 94 the 40-day clock stops from the day the council asks for more information until you answer. It stops only if the council asks within 25 days of lodgement. A missing survey, flood report or stormwater plan is the usual cause, and every day it takes you to answer is added to the total.

2. Sydney Water. Sydney Water says council will not grant consent unless it has approved your building plans. If the pool is near one of its pipes, a water servicing coordinator handles the application, and an ‘out of scope’ referral that isn't complex generally gets conditions within 42 days. Checking where the sewer runs before the design is fixed is what keeps this at zero days.

3. Being on the wrong route. A lot with a mapped heritage item, an uncertified flood-affected part, or excavation deeper than 1m within 40m of a waterbody cannot use a CDC for that part, as our Parramatta cost guide explains. Find that out from the section 10.7 planning certificate before paying for drawings.

Collecting quotes does not have to wait for any of this. Builders quote on the site, so the quote and approval timelines can overlap.

Common questions

How long does a pool CDC take in Parramatta?

The certifier must decide within 10 days for a pool-only CDC, or 20 days if it also covers a new dwelling or an addition, under section 133 of the Environmental Planning and Assessment Regulation 2021. Allow for Sydney Water's building plan approval first, and a 7-day notice to neighbours before work starts if your certificate carries that condition.

How long does City of Parramatta take to assess a DA?

The NSW council league table shows City of Parramatta averaging 92 assessment days and 12 days to lodge in its August 2026 snapshot. Across the 2025–26 monthly snapshots, assessment averaged 68 to 87 days. These averages cover all DA types, not only pools.

What happens if Parramatta council doesn't decide my pool DA in 40 days?

It is a deemed refusal under section 91 of the Regulation, which gives you a right of appeal. It does not stop council from deciding later. The 40 days pauses while a request for more information is outstanding, if council made the request within 25 days of lodgement.

Do I need Sydney Water approval for a pool in Parramatta?

Yes, a building plan approval through Sydney Water Tap in, which costs $24.15 in 2026–27. If the pool doesn't affect Sydney Water's pipes it is issued online straight away. If it does, a water servicing coordinator handles it, and an out-of-scope referral generally gets conditions within 42 days.

Can I get quotes before my pool is approved?

Yes. Builders price the site and the design, not the approval, so quotes can be collected while the CDC or DA is being assessed. Some builders will prepare and lodge the approval as part of their contract; ask each one who lodges it and who pays if it is refused.
