When Does the DCA Get Involved in Your DA?
The DCA becomes involved when your development requires referrals to state agencies (Transport, Health, RFS) or when councils request concurrence coordination — typically for DAs with state significance, complex infrastructure impacts, or multi-agency overlap.
Not every DA goes through the DCA. Here's when it applies:
Developments Requiring DCA Coordination
1. State Significant Development (SSD) — Always coordinated by DCA
2. DAs requiring agency concurrences — Transport for NSW (road access), NSW Health (hospital catchments), Rural Fire Service (bushfire-prone land)
3. Multi-council developments — Sites spanning LGA boundaries
4. Complex infrastructure projects — Subdivision with public road dedication, utility easements
5. Pre-DA requests for complex projects — 10+ units, mixed-use, heritage impacts
Developments NOT Requiring DCA Coordination
- Complying Development Certificates (CDC) — Handled by private certifiers or council
- Simple residential DAs — Single dwelling, no agency referrals needed
- Section 4.55(1) modifications — Minor modifications (unless they trigger new referrals)
- BASIX-only assessments — Energy/water compliance doesn't require DCA

How the DCA Referral Process Works (Step-by-Step)
The DCA referral process has 5 stages: lodgement → referral check → agency consultation → concurrence issuance → determination. From 1 July 2026, agencies have 21 days to respond, or concurrence is automatically deemed given.
Here's the workflow for a typical DA requiring DCA coordination:
Stage 1: DA Lodgement (Day 0)
- Applicant submits DA via NSW Planning Portal
- Council case manager reviews for completeness
- DCA flag triggered if referral agencies are required
Stage 2: Referral Check (Days 1–5)
- Council invites DCA to complete referral check via Planning Portal
- DCA identifies which agencies need to be consulted
- DCA sets response deadline (21 days from referral date)
Stage 3: Agency Consultation (Days 6–26)
- DCA sends referral requests to agencies (Transport, Health, RFS, etc.)
- Agencies review and provide conditions or objections
- Critical change: If agency doesn't respond by Day 26, concurrence is automatically deemed given
Stage 4: Concurrence Issuance (Days 27–30)
- DCA consolidates agency responses
- If conflicts exist (e.g., Transport wants wider driveway, RFS wants narrower), DCA resolves
- DCA issues binding concurrence with conditions
Stage 5: Council Determination (Days 31–42)
- Council receives DCA concurrence
- Council proceeds to determination (approval, approval with conditions, or refusal)
- Total timeline: 6–8 weeks vs. previous 10–14 weeks

Real-World Example: 12-Unit Townhouse DA in Merrylands
In March 2026, giantA coordinated a 12-unit townhouse DA in Merrylands that required Transport for NSW concurrence (due to bus route frontage) and RFS concurrence (due to bushfire-prone land). Under the old system, this took 14 weeks. Under the new DCA process, we estimate 8 weeks.
Project Details
- Location: Merrylands, NSW (Cumberland Council LGA)
- Development: 12-unit townhouse development with basement parking
- Referral Agencies Required: Transport for NSW (road access), Rural Fire Service (bushfire)
- Complexity: Medium (standard residential, but two agency concurrences)
Timeline Comparison
| Phase | Old System (Pre-July 2026) | New DCA System (Post-July 2026)
Transport for NSW concurrence | 6 weeks (no deadline) | 3 weeks (21-day deadline) |
| RFS concurrence | 5 weeks (no deadline) | 3 weeks (21-day deadline) |
| Conflict resolution | 3 weeks (escalation to Planning Dept) | 1 week (DCA resolves in-house) |
| Council determination | 3 weeks | 3 weeks (unchanged) |
| Total | 19 weeks | 11 weeks |
Time saved: 8 weeks (42% reduction)
Cost impact: Reduced holding costs (~$15,000 for 8 weeks on a $2.5M land parcel), reduced consultant fees (fewer revision cycles)

Section 4.55(1) Modifications: What Changed in March 2026?
From 21 March 2026, Section 4.55(1) modifications (minor modifications to development consents) have clarified rules about what can be modified without re-notification — and the DCA now coordinates modifications that trigger new agency referrals.
The March 2026 Planning Portal release introduced clarified guidance on Section 4.55(1) of the Environmental Planning and Assessment Act 1979. Here's what changed:
Before March 2026
- Unclear what constituted a "minor" modification
- Councils interpreted differently (some required re-notification for facade changes)
- No DCA involvement in modifications
After March 2026
Section 4.55(1) modifications can now be processed without re-notification if:
1. No additional agency referrals triggered — If the modification doesn't change road access, bushfire risk, or other agency concerns
2. No increase to building envelope — Height, FSR, site coverage remain unchanged
3. No new environmental impacts — Noise, overshadowing, privacy unaffected
4. No change to approved use — Residential stays residential, commercial stays commercial
If the modification triggers new referrals (e.g., adding a second crossover requires Transport concurrence), the DCA coordinates the referral using the same 21-day deadline process.

DCA Pre-DA Service: Should You Use It?
The DCA offers a voluntary pre-DA coordination service for complex developments (10+ units, mixed-use, state significance). For straightforward residential DAs, skip it. For complex projects, it can save 6–10 weeks by identifying agency concerns upfront.
When to Use DCA Pre-DA Service
| Scenario | Recommendation | Why
| Single dwelling, no referrals | ❌ Skip | No agency coordination needed |
Duplex/Townhouse (2–9 units) | ⚠️ Optional | May benefit if site has complexity (bushfire, flood, heritage) |
| Multi-unit (10+ units) | ✅ Recommended | Multiple agency referrals likely |
| Mixed-use development | ✅ Recommended | Commercial + residential triggers multiple agencies |
| State Significant Development | ✅ Mandatory | SSD always requires DCA coordination |
Pre-DA Process
1. Request pre-DA meeting via Planning Portal ($500–$1,500 fee depending on complexity)
2. DCA invites relevant agencies (Transport, Health, RFS, council)
3. Pre-DA meeting held (virtual or in-person, 1–2 hours)
4. DCA issues pre-DA advice letter (non-binding but highly influential)
5. Applicant incorporates feedback into formal DA
ROI Example: A $2,000 pre-DA investment that prevents a 6-week referral delay saves ~$12,000 in holding costs (on a $2M land parcel at 6% p.a.).

Common DCA Pitfalls (And How to Avoid Them)
Based on our experience tracking DCA implementations since March 2026, here are the top 5 pitfalls we've seen applicants encounter — and how to avoid them.
Pitfall 1: Assuming All Agencies Have 21 Days
Reality: The 21-day clock starts when DCA sends the referral, not when you lodge your DA. If council takes 2 weeks to invite DCA, your timeline just extended by 2 weeks.
Fix: Request DCA invitation immediately after lodgement. Follow up with council case manager on Day 3 if no DCA invitation sent.
Pitfall 2: Incomplete Referral Information
Reality: Agencies can request "further information" during the 21-day period, which pauses the clock.
Fix: Include all required reports upfront (Traffic Impact Assessment, Bushfire Assessment, Flood Study) even if council doesn't explicitly request them.
Pitfall 3: Relying on Deemed Concurrence
Reality: While deemed concurrence exists, councils may hesitate to proceed without explicit agency approval for high-risk developments.
Fix: Proactively follow up with agencies in week 3. Most will issue concurrence rather than risk being deemed.
Pitfall 4: Not Using Pre-DA for Complex Projects
Reality: Applicants skip pre-DA to save $1,500, then spend $15,000+ in redesigns after agency objections.
Fix: For 10+ unit developments, budget for pre-DA. The ROI is 10:1 or better.
Pitfall 5: Confusing DCA with Council Approval
Reality: DCA coordination doesn't guarantee council approval. Council can still refuse based on local planning controls (LEP, DCP).
Fix: Address both state agency concerns (via DCA) AND local council concerns (via pre-DA with council or design review).

Cost Implications: What Does DCA Coordination Cost?
DCA coordination itself is free — it's funded by the NSW Government. However, the reports required for agency referrals (traffic, bushfire, acoustic) typically cost $3,000–$15,000 depending on development complexity.
Typical Referral Report Costs
| Report Type | Cost Range | When Required
| Traffic Impact Assessment | $3,000–$8,000 | Transport for NSW concurrence (road frontage, crossover) |
| Bushfire Assessment (BAL) | $1,500–$4,000 | RFS concurrence (bushfire-prone land) |
| Acoustic Report | $2,000–$5,000 | NSW Health (near hospitals), noise-sensitive uses |
| Flood Study | $2,500–$6,000 | Council/DFS (flood-prone land) |
| Heritage Impact Statement | $4,000–$10,000 | Heritage-listed sites or conservation areas |
| Total (typical 12-unit DA) | $8,000–$15,000 | Multiple referrals |
Note: These costs are the same whether DCA coordinates or not — the DCA doesn't add fees, it just manages the process.

FAQ: Development Coordination Authority (DCA) NSW 2026
Q1: Does the DCA approve or refuse my DA?
No. The DCA coordinates agency referrals and issues concurrences, but the consent authority (council or Planning Secretary) makes the final approval/refusal decision. Think of the DCA as a traffic controller, not the judge.
Q2: How long does DCA coordination add to my DA timeline?
DCA coordination typically takes 4–6 weeks within the overall DA process. However, by enforcing 21-day agency deadlines, it often reduces total referral time by 4–8 weeks compared to the old system.
Q3: Can the DCA refuse my DA if agencies object?
The DCA can issue a concurrence with conditions, but it cannot refuse a DA. If an agency objects, the DCA will attempt to resolve the conflict. If unresolved, the objection goes to the consent authority for consideration.
Q4: Do I need a planner to work with the DCA?
No, but for complex developments (10+ units, mixed-use), a planning consultant experienced with DCA processes can navigate referrals more efficiently and avoid common pitfalls.
Q5: What happens if the DCA misses its own deadlines?
The DCA is subject to the same deemed concurrence rules. If the DCA doesn't coordinate agency responses within the set timeframe, the concurrence is automatically deemed given.
Q6: Does the DCA apply to CDC (Complying Development)?
No. CDC applications are handled by private certifiers or council and do not require DCA coordination. The DCA only applies to DAs requiring state agency referrals.
Q7: Can I request DCA coordination if my DA doesn't require it?
No. DCA involvement is triggered by statutory requirements (agency referrals) or council request. You cannot voluntarily opt into DCA coordination for simple DAs.
Q8: How do I track my DCA referral status?
Log into the NSW Planning Portal, navigate to your DA, and check the "Referrals" tab. The portal shows which agencies have been invited, which have responded, and the deadline date.

Key Takeaways for giantA Clients
The DCA reforms are net-positive for development applicants — faster timelines, clearer processes, and enforced agency deadlines. Here's what to do:
1. For simple residential DAs (single dwelling, duplex without referrals): No action needed. Process unchanged.
2. For multi-unit DAs (10+ units, mixed-use): Budget for DCA coordination timeline (8–12 weeks for referrals) and consider pre-DA service ($1,500 well spent).
3. For Section 4.55(1) modifications: Check if modifications trigger new referrals. If yes, DCA coordinates. If no, council processes directly.
4. Track your DA via Planning Portal: The Referrals tab shows real-time DCA status.
5. Engage early with giantA: We can identify DCA-triggering issues during concept design, before you spend on reports.
