When your sign requires approval, you have two main pathways: a Development Application (DA) assessed by your local council, or a Complying Development Certificate (CDC) assessed by a private certifier. Understanding the difference can save you 6–10 weeks of waiting time.
DA vs CDC — Quick Comparison
| Factor | DA (Council) | CDC (Private Certifier) |
|---|---|---|
| Who assesses | Local council planner | Private certifier you appoint |
| Typical timeframe | 4–12 weeks | 10–20 business days |
| Cost | $200–$2,500 council fee | $400–$1,500 certifier fee |
| Flexibility | Discretionary — council can impose conditions | Strict — sign must meet all CDC standards |
| Public notification | Sometimes required (neighbours notified) | Not required |
| Right of appeal | Yes — Land and Environment Court | Limited |
| Heritage areas | Available (often required) | Not available |
When Can You Use the CDC Pathway?
Not all signs qualify for CDC. The sign must meet every standard set out in the State Environmental Planning Policy (Exempt and Complying Development Codes) or equivalent in your state. Typical CDC eligibility criteria for business signs:
- Located in a commercial or business zone (not residential or rural)
- Sign area within prescribed limits (typically 3m² to 20m² depending on sign type)
- Not in a heritage conservation area or on a heritage item
- Not a freestanding pylon sign above a certain height
- Illuminated signs must meet luminance standards
- No animated or video components (or within digital sign specific codes)
When Do You Need a Full DA?
You must use the DA pathway when:
- The sign is in a heritage conservation area or on a heritage-listed building
- The sign exceeds CDC size or height limits
- The sign type (e.g. roof sign, billboard) isn’t covered by CDC codes
- The property is in a residential zone
- Council’s Local Environmental Plan (LEP) requires DA for all signage in that zone
How to Choose the Right Pathway
Follow this process:
- Check if your sign qualifies as exempt development — if yes, no approval needed
- Check your state’s CDC codes — does the sign meet every standard?
- If yes to CDC standards: engage a private certifier for fastest approval
- If no to CDC standards: lodge a DA with your local council
- If heritage is involved: always DA, allow 12–20 weeks
