The following information relates to rule 3.5 and the accuracy requirements for boundaries defined by reference to permanent structures.
A permanent structure boundary may be coincident with a permanent structure or may be a line in space referenced to a permanent structure (ie a non-coincident permanent structure boundary).
The accuracy of a permanent structure boundary relies entirely on the accuracy of its relationship with the permanent structure.
Where a new permanent structure boundary is being defined, the underlying parcel boundaries may be defined by adoption.
Note that if the permanent structure boundary is within 1 m of another boundary (class A) or 3 m (class B) and the relationship between the two boundaries cannot be accurately obtained (refer rule 3.5), the underlying parcel boundary may need to be defined by survey.
Where the permanent structure boundary is not coincident with the permanent structure, the boundary must be witnessed by a clearly identified point on the structure [r 3.5(a)] and the relationship between the boundary point and this 'witness point' must comply with the accuracy specified in rule 3.6 [r 3.5(b)].
These requirements do not apply to boundaries of existing units and common property defined under prior rules where no changes are being made to the parcel boundaries, appellation, and title (refer to rule 19).
The accuracy between a permanent structure boundary and another boundary must comply with the accuracy specified in rule 3.3 where the boundaries are close to each other [r 3.5(c)]
These requirements do not apply to boundaries of existing units and common property defined under prior rules where no changes are being made to the parcel boundaries, appellation and title (refer to rule 19).
