Strata plan of building alteration

A building alteration plan must be lodged when the manner in which a strata lot boundary is defined has been changed by the removal of a structure or the building of a structure. See section 19 Strata Schemes Development) Act 2015. The purpose of the plan is to redefine the relevant boundaries in the original position. The plan does not define land (i.e. lots or common property).

  • No new boundaries are created
  • The common property is not affected
  • If it is the intention to alter the position of a lot boundary a Strata plan of subdivision should be lodged.

Location plan

A location plan is not required unless the new structure is within 2 metres of a parcel boundary.

Floor plan

The floor plan is prepared in the same manner as the original floor plan. However there are some other things to consider:

  • It is only required to show the relevant parts of lots and the adjoining information.
  • In some circumstances it may be desirable to show the entire floor of a building so it is clear where the lots are situated.
  • The lot numbering must remain the same as immediately prior to the plan.
  • It is not required to show areas.
  • Boundaries previously defined by a face of a structure which has been demolished must now be defined by line boundaries.
  • Boundaries which were previously defined by line only may now be defined by the face or another part of a structure.

Building alteration plans require a surveyor’s certificate and must be executed by the registered proprietor (and mortgagee etc) on either side of the subject boundary. This may include the owners corporation.
