Under The Environmental Planning and Assessment Act 1979, 'development' is defined as:
· the use of land;
· the subdivision of land;
· the erection of a building;
· the carrying out of work;
· the demolition; or
· any other matter controlled by an environmental planning instrument.
To obtain development consent, you must lodge a Development Application with Hunters Hill Council.
Some minor development, called Exempt Development, does not require consent. Another type of development, called Complying Development, requires a Complying Development Certificate prior to commencing the use and may be issued by either Council or a private certifier. The relevant controls can be found in Councils Development Control Plans.
