Strategic Development Zone (SDZ) designation is intended for lands where, in the opinion of the Government, specified development is of economic or social importance to the State. It results in a very specific planning process for buildings within the zone.

The two principal elements to delivery of development under the SDZ mechanism are designation as an SDZ by Government Order and adoption of a Planning Scheme for the designated lands. In order for lands to be designated as an SDZ it must be approved by Government Order. The procedure involved the GDA applying to the Minister for the Environment, Heritage & Local Government for Government designation.
