In Queensland, all “Building Work” is Assessable Development that requires a Building Approval to be issued by a Building Certifier prior to the commencement unless it is prescribed by the Building Act 1975 to be self-assessable (known as Accepted Development subject to relevant provisions) or exempt (known as Accepted Development).

It is important to note that except for issues of minor maintenance, there are no provisions for that allow building work without an approval the basis of replacing a building or structure “like for like”.

In broad terms, “Building Work” is defined by the Building Act as building, repairing, altering, underpinning, moving or demolishing a building or other structure and filling or excavating incidental to these activities.

Yes, bathrooms, laundries, ensuites and W.C’s carry specific provisions for waterproofing, ventilation, glazing and emergency access and may trigger the requirement to install graded falls to floor wastes, the installation of fire collars to new penetrations or the installation of new termite protection measures.

Alterations or renovations to these areas have the potential to adversely affect occupant safety and the term structural adequacy of the building and are considered to be Assessable Development. Typically an existing and proposed floor plan will be required for assessment.

Yes, most likely your Unit or Apartment contains passive acoustic and fire protection measures prescribed by the National Construction Code that largely go unnoticed by the owner or occupier. Sound rating of services, walls, floors and ceilings, non-combustibility requirements for various elements, fire rating of internal walls and shafts, fire rated access panels, fire collars, fire doors and smoke detection and alarm systems all serve to maintain the amenity and fire safety of both the unit or apartment and the building as a whole.

Internal alterations and renovations to Units or Apartments has the very real potential to adversely affect occupant safety and the structural adequacy of the building, evidence from the Grenfell Tower fire suggests that unapproved alterations and replacement of seeming innoxius elements contributed to the spread of fire, accordingly internal alterations and renovations to Units or Apartments and are considered to be Assessable Development. Typically an existing and proposed floor plan will be required for assessment, in some instances structural engineering details and specific system details for fire rated construction will also be required.

Retaining Walls may be considered “Accepted Development subject to relevant provisions” (Previously called Self-Assessable Development) meaning no Building Approval is required where all of the following criteria are met:

  • there is no surcharge loading over the zone of influence for the wall (i.e. the no loading on the soil behind the wall for a distance equal to the height of the wall) and
  • the total height of the wall, and of the fill or cut retained by the wall, is no more than 1m above the natural ground surface; and
  • the wall is no closer than 1.5m horizontally from a building or another retaining wall; and
  • it does not form part of the fencing for a swimming pool.

If your proposed retaining walls is inconsistent with one or more of these elements a Building Approval will be required before commencing the building work.

If your proposed retaining walls meets the criteria for “Accepted Development subject to relevant provisions”, no formal Building Approval is required however the building work it must still comply with the Building Code of Australia, the Queensland Development Codes and Planning Scheme provisions that may apply in your area and ensuring compliance is the responsibility of the land owner.

Fences may be considered “Accepted Development subject to relevant provisions” (Previously called Self-Assessable Development) meaning no Building Approval is required where all of the following criteria are met:

  • the fence is no higher than 2m above the natural ground surface (Note: If the fence is located above a retaining wall, then the 2.0m height measurement includes the combined height of fence and retaining wall height) and
  • it does not form part of the fencing for a swimming pool.

If your proposed fence is inconsistent with one or more of these elements a Building Approval will be required before commencing the building work.

If your proposed fence meets the criteria for “Accepted Development subject to relevant provisions”, no formal Building Approval is required however the building work it must still comply with the Building Code of Australia, the Queensland Development Codes and Planning Scheme provisions that may apply in your area and ensuring compliance is the responsibility of the land owner.
