How Long Does Council DA Approval Really Take in NSW?

If you’re planning a renovation or new dwelling in NSW, one of the biggest unknowns is:

“How long will council approval actually take?”

Officially, many residential DAs aim for around 40–60 days of assessment time. In reality, projects can run from a clean 6–8 weeks through to many months, and occasionally much longer.

This article explains:

• The official targets vs real-world experience
• What’s slowing things down
• What you can do to avoid blowing out your timeline

The Official Line: Statutory Timeframes

Guidance for typical residential DAs often talks about 40–60 days from lodgement to determination, but that’s only if:

• Your application is complete and correct
• Council doesn’t need major redesign
• Referral agencies respond on time
• You respond quickly to Requests for Information On paper, that sounds achievable. On the ground… it’s more complicated.

Real-World DA Timeframes in 2025

Recent data and industry reviews show:

• Many councils are taking longer than the Government’s expectations, with some averaging over 100 days for certain DA types.

• There’s active pressure from the NSW Government for “slow” councils to improve, including public league tables and intervention powers.

• Business groups estimate DA-related red tape costs hundreds of millions of dollars per year in lost time and compliance effort. For a straightforward house extension in a typical suburb, a 3–4 month window from DA lodgement to consent is pretty common once you account for:

• Council registration and initial checks

• Neighbour notification periods

• Requests for Information

• Internal and external referrals

The Big Factors That Affect Your DA Timing

• Quality of the ApplicationMissing plans, surveys, reports or checklists can see your DA rejected at lodgement or put on hold.

• Complexity of the Site and DesignHeritage, flooding, bushfire, significant trees, traffic – all add time.

• How Far You’re Pushing the RulesIf you’re seeking big variations to height, FSR, setbacks or character controls, expect more back-and-forth.

• Council Workload and ResourcingSome councils are stacked with applications or have staff shortages. The league table data makes these differences pretty obvious.

• How Quickly You RespondEvery Request for Information adds days or weeks if you and your team take time to reply.

What Can You Do as a Homeowner?

• Allow for approval time in your program – don’t promise builders or tenants a start date based on best-case timing.
• Invest in good documentation – it’s cheaper than months of delay.
• Be responsive – treat council and consultant requests like time-sensitive tasks. If you’re wondering what timeframe is realistic for your council and project type, Planland can give you an honest estimate based on recent data and local experience.
