Plain-language definition

Definition of Setback from the principal residential unit

The required separation between a detached granny flat and the principal home.

Also called: main-home setback

Two metres, checked under two laws

The NES-DMRU requires at least 2 m between the DMRU and the principal residential unit. Schedule 1A separately requires an exempt dwelling to be at least 2 m from any other residential building.

The number is the same, but the legal tests are separate. Another nearby sleepout or dwelling may therefore matter to Schedule 1A even when it is not the principal home named by the planning standard.

Measure the shortest separation

Parallel walls can appear comfortable while a rotated corner, porch or roof projection is closer. Label the shortest distance and the points measured on the site plan, then have the designer or council confirm the rule’s method for the actual design.

Recheck every relocation

Moving the footprint can alter boundary setbacks, fire design, access, hazards, earthworks and service connections. Treat relocation after the PIM as a design change, not an informal site instruction.
