If your development doesn’t fall under Exempt Development or Complying Development, you need to apply for development consent and lodge a Development Application (DA).
A development is considered local development if a local environmental plan (LEP) or State environmental planning policy (SEPP) says that development consent is required before the development can take place.
The procedures for applying for development consent, the level of environmental assessment required, the notification required, and appeal rights will differ depending on how a development is categorised. These categories include designated development, integrated development and advertised development.
Use the NSW Department of Industry & Environment's guide to learn about the development assessment process.
A development application does not permit proposed building works to commence. Please also refer to the information below regarding post consent certificates.
