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

Typical timeframe4–12 weeks10–20 business days
Cost$200–$2,500 council fee$400–$1,500 certifier fee
FlexibilityDiscretionary — council can impose conditionsStrict — sign must meet all CDC standards
Public notificationSometimes required (neighbours notified)Not required

Heritage areasAvailable (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

  1. Check if your sign qualifies as exempt development — if yes, no approval needed
  2. Check your state’s CDC codes — does the sign meet every standard?
  3. If yes to CDC standards: engage a private certifier for fastest approval
  4. If no to CDC standards: lodge a DA with your local council
  5. If heritage is involved: always DA, allow 12–20 weeks

  • QLD — Accepted development under local government planning schemes
  • SA — Accepted development under Planning and Design Code
  • WA — Permitted development under local planning schemes

Frequently Asked Questions

Is a CDC faster than a DA for sign permits?
Yes u2014 significantly faster. A CDC is assessed by a private certifier you appoint and typically takes 10u201320 business days. A council DA takes 4u201312 weeks, sometimes longer. The trade-off is that CDC requires your sign to meet strict pre-set standards with no flexibility.
In NSW and VIC, some illuminated signs qualify under CDC codes if they meet luminance standards (typically under 300 cd/mu00b2 in residential-adjacent areas). LED and digital signs have specific CDC codes in NSW. Check your state's SEPP or planning scheme for illuminated sign CDC criteria.
Private certifier fees for sign CDCs typically range from $400 to $1,500 depending on sign complexity, number of signs, and the certifier. This is usually comparable to or slightly higher than council DA fees, but the time saving of 4u20138 weeks is the main benefit.
Exempt development requires no approval at all and no certification u2014 the sign just needs to meet the criteria. Complying development requires a CDC certificate from a council or private certifier confirming the sign meets the standards. Both are faster than a DA.
