The Medium Density Housing Code, also known as the Low Rise Housing Diversity Code, is legislation created by the NSW Government to override Council’s planning controls to allow larger dual occupancies (duplexes), terraces, and permits manor houses in suburban areas. Manor houses are up to four units on a single block.

Dual occupancies, manor houses, and terraces to be carried out under a fast–tracked complying development approval process, will not need approval from Council.  Only neighbors are required to be informed of these developments and have no right to object.​

Dual occupancies, manor houses, and terraces built as complying development are only allowed in R1, R2, R3, and RU5 zones where this type of housing is already permitted under a council’s Local Environmental Plan (LEP).
