Building Commissioner makes first prohibition order
under the Residential Apartment Buildings (Compliance and
Enforcement Powers) Act

Regular readers will recall our previous discussion on the
Residential Apartment Buildings (Compliance and Enforcement Powers)
Act 2020 (RAB Act), which has been in force since
1 September 2020, in our 

 article, or at one of our webinars.

The RAB Act gives the Building Commissioner power to (among
other things) prevent the issuing of occupation certificates or the
registration of a strata plan for residential apartment buildings
where certain requirements are not met or if there is a serious

A prohibition order “is the ultimate signal to the
developer that they must resolve any noncompliance or face never
having the building sold or occupied”.

Orders made under the RAB Act are listed on a 
public register
 on the NSW Fair Trading website and the
Building Commissioner has lost no time in flexing his new powers,
with the public register showing a Prohibition Order and a Building
Work Rectification Order, each issued in late September in relation
to a project in Caringbah South.


Compliance officers conducted an inspection of the residential
apartment building in question on 14 September 2020. During the
inspection, it was observed that building work carried out had
resulted in serious defects in relation to three elements,

  • cladding, in relation to cavity masonry and masonry veneer
    construction adjoining the ground floor podium structural concrete

  • waterproofing, at the external ground floor podium structural
    concrete slab, including terraces and planter boxes

  • installation of the elevator, which provided access from the
    basement level car park directly into residential lots.

Under section 9 of the RAB Act, the Building Commissioner may
make an order prohibiting the issue of an occupation certificate or
the registration of a strata plan for a residential apartment
building if he is satisfied that serious defects exist in the

Under section 33 of the RAB Act, if the Building Commissioner
has a reasonable belief that building work was or is being carried
out in a matter that could result in a serious defect, a building
work rectification order may be issued, requiring a developer to
carry out or refrain from carrying out building work as specified
in the order, to eliminate, minimise or remediate the serious
defect or potential serious defect. The Building Work Rectification
Order (BWRO) issued by the Building Commissioner
on 30 September 2020 was issued in relation to the cladding and
waterproofing defects only.

Nature of serious defects

A ‘serious defect’ is defined in section 3 of the RAB
Act to include the following (among other things):

  • a defect in a building element attributable to a failure to
    comply with the performance requirements of the Building Code of
    Australia (BCA) or the relevant Australian
    Standards (AS); or

  • a defect in a building product or building element that is
    attributable to defective design, defective or faulty workmanship
    or defective materials, that causes or is likely to cause the
    inability to inhabit or use the building (or part thereof) for its
    intended purpose, or the destruction of the building or any part of
    the building.

In relation to the cladding, the compliance officers found no
evidence of cavity flashing discharging from the wall to turn down
and over the waterproofing membrane at the planters and adjoining
the entire ground floor podium slab area during their inspection.
This absence prevents the continuity of the flashing and waterproof
membrane installation. The Prohibition Order (PO)
indicated that the building work constituted a serious defect due
to a failure to comply with the performance requirements of clause
2 of AS 4654.2 and that the defect was attributable to either
defective design or defective workmanship, which caused or was
likely to cause the inability to inhabit or use the building for
its intended purpose or the destruction of the building.

The compliance officers found that insufficient heights for
termination of the planter and podium waterproofing had been
allowed on the external ground floor podium structural concrete
slab including terraces and planter boxes. This was found to
constitute a serious defect for the same reasons as the

In relation to the elevator, the compliance officers observed
the unpacking, preparation and component assembly for the elevator
installations. The developer, however, was unable to provide
clarification of details and the personnel carrying out the work
were not elevator installation technicians. A week later, a notice
was issued requesting further information relating to the design,
certification and installation of the elevators. The information
had not been received in its entirety by the date of the PO. The
elevator installation was found to be a serious defect due to its
failure to comply with the BCA, and the defect was attributable to
either defective design or defective workmanship, which caused or
was likely to cause the inability to inhabit or use the building
for its intended purpose or the destruction of the building.

The PO remains in force until revoked by the Building
Commissioner or Secretary. Under the BWRO, the developer was
ordered to remediate the cladding and waterproofing defects within
28 days and to notify within two business days of completion. The
BWRO remains in force until either complied with or revoked by the
Building Commissioner or Secretary.

Be warned

This first suite of orders sends a message that the Building
Commissioner is willing to exercise, and has shown no hesitation in
exercising his new powers. In doing so, it is clear that audit
inspections will encompass not just an examination of work carried
out but also extend to irregularities observed on site in work in
progress. The nature of the defects subject of the BWRO
confirm that the potential for water penetration in its various
forms is one of the main areas of focus in the audit process.

This is a level of regulatory oversight not before seen in the
NSW building industry.

HomeBuilder scheme: construction industry warns of
‘bust’ if program isn’t extended
The scheme has a looming December 31 end date everywhere

In Australia, our construction industry comprises nine per

the most digitally mature organisations are recognising the need
for this (29 September 2020).
