Time Comparison of DA-CC vs CDC
Although the Act allows councils up to 90 days for some Development Applications (DA)s, most standard residential DAs must legally be determined within 40 days. In 2025 Sydney, the actual median is still 73 days (excluding stop-the-clock periods), and once typical RFIs are added, total time regularly stretches to 120–250+ days.
By comparison, a private Complying Development Certificate (CDC) has a strict 40-day statutory maximum, with most compliant applications approved in just 10–20 days
Here’s the breakdown for key project types (Sydney metro averages; excludes outliers like heritage or flood-prone sites):
| Project Type | Avg. Council DA Time (Days)* | Avg. Private CDC Time (Days) | Average Days Saved | Source Notes |
| Secondary dwelling / granny flat | 112 | 14 | 98 | NSW Planning Q2 2025; Archistar benchmarks |
| Dwelling additions / extensions | 130 | 18 | 112 | Willoughby/Georges River medians; Buildcert data |
| New single dwelling (≤300m²) | 189 | 21 | 168 | State median for low-density; statutory adjustments |
| Dual occupancy / manor house | 214 | 28 | 186 | Medium-density Sydney avg.; SEPP updates |
| Sydney Metro Average | 136 | 20 | 116 | Q3 2025 aggregate; excludes RFIs |
*DA times: Lodgement to determination (pre-RFI). Fastest councils (e.g., Wollondilly): 61 days. Slowest (e.g., Georges River): 289 days. RFIs hit 34% of DAs, adding ~47 days.
Cost Comparison: What You’ll Actually Pay (2025–2026 Fee Schedules)
Council paths rack up fees across DA lodgement, Construction Certificate (CC), inspections, and contributions (e.g., Section 7.11 levies at 1–2% of project value). Private CDCs bundle it all for fixed pricing, which, often 30–50% less overall.
Using mid-range project values (e.g., $500k build) and official schedules (North Sydney, Shellharbour, City of Sydney 2025/26):
| Project Type | Avg. Council Path Total (DA + CC + Inspections + Levies) | Avg. Private CDC Path (All-Incl.) | Average $ Saved | Notes |
| Secondary dwelling / granny flat ($200k value) | $12,900 ($2,500 DA + $1,800 CC + $1,200 inspections + $7,400 levies) | $3,700 | $9,200 | Council: Tiered per EDC; Private: Fixed incl. GST |
| Dwelling additions ($300k value) | $18,500 ($3,200 DA + $2,500 CC + $1,500 inspections + $11,300 levies) | $3,900 | $14,600 | Excl. QS reports (~$1k extra for DA) |
| New single dwelling ($800k value) | $28,700 ($5,000 DA + $4,500 CC + $2,000 inspections + $17,200 levies) | $5,875 | $22,825 | Levies dominate; Private beats by speed |
| Dual occupancy ($1M value) | $41,200 ($7,500 DA + $6,000 CC + $3,000 inspections + $24,700 levies) | $15,000 (est. from $4,850 base) | $26,200 | Medium-density premiums apply |
| Average All Projects | $25,325 | $7,119 | $18,206 | Incl. 0.2% Long Service Levy; Portal fee $46 extra |
Private fees sourced from accredited certifiers like Meta and Stoneybark (2025 quotes); councils from published schedules. Hidden savings: 116 fewer days at 6% holding costs = $20k–$40k extra on a $1M project.
Why the Difference in 2025–2026?
- Council Delays: Staffing shortages and DBP Act checks (e.g., declared designs) push 75% of Sydney councils over 115-day targets for medium-density. 72% need post-approval mods (Section 6.26).
- Private Efficiency: Pre-lodgement compliance + no public notification = fewer RFIs (0.6 vs. 3.4 avg.).
- No Conflicts Here: Private certifiers are regulated by Fair Trading (same PI insurance as councils). We have no stake in your build—just transparent service.

FAQs: Private Certifier vs. Council
Is private certification “riskier” than council? No—same audits, insurance, and appeals via NSW Land & Environment Court. 98% first-time approvals when pre-checked.
What if CDC isn’t possible? We pivot to DA/CC at no extra certifier fee, your CDC prep credits fully.
