Before you build, extend or demolish in NSW, you need to know which approval path applies. There are three main options, and choosing the right one can save months.
1. Exempt development
Some minor works need no planning or building approval at all, provided they meet every standard in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. Examples can include small sheds, some low retaining walls, decks and minor internal works. If any standard is not met, the work is not exempt.
2. Complying development certificate (CDC)
A CDC is a fast-track approval for work that meets set standards for things like height, setbacks and site coverage. It can be issued by council or a private certifier, and combines planning and construction approval in one. If the application is complete and complies, CDCs are generally determined within about 20 days.
Common CDC projects include many new houses, alterations and additions, granny flats, swimming pools and demolition.
3. Development application (DA)
A DA is assessed by council on its merits against the local environmental plan and development control plan. It usually involves neighbour notification and takes longer. After DA approval, you also need a construction certificate before building.
A DA is usually needed when a project does not meet CDC standards, or the site has constraints such as heritage listing, a heritage conservation area, certain flood or bushfire categories, or other exclusions.
How to work out which you need
- Get your property's planning certificate and check its zoning and constraints on the NSW Planning Portal.
- Check whether the work meets exempt standards.
- If not, check whether it can meet the complying development standards.
- If not, prepare a DA.
After approval
Most approved building work needs a principal certifier, inspections at critical stages and an occupation certificate before the building is used.

Frequently asked questions
What is the difference between a DA and a CDC?
A CDC is a fast-track approval for work meeting set standards, issued by council or a private certifier. A DA is a merit assessment by council and usually takes longer.
How long does a CDC take in NSW?
If the application is complete and complies, generally around 20 days.
Do I need a construction certificate after a DA?
Yes. A DA is planning approval; a construction certificate is needed before building starts.
