Australia's New South Wales Building Industry Reforms


What has Happened?

The NSW Government has passed legislation to further regulate the design and construction of residential buildings. These measures respond to the loss of public confidence resulting from high profile design and building quality issues.

To address these ongoing issues, significant reforms were passed by NSW Parliament this month in the form of:

The key changes include:

What Else has Happened in This Space?

Amendments already made to the Environmental Planning and Assessment Regulation 2000 in 2018 which:

Overview of the Residential Apartments Act

The Residential Apartments Act will commence on 1 September 2020. Exercise of functions under the Act apply to:

The Act will also apply to mixed-use developments where only part of the building is for residential use.

Who Do These Amendments Affect?

The Residential Apartments Act will impose additional obligations on "developers" described as:

Directors and persons in management positions may also be personally liable if they knowingly authorise or permit contraventions of the Residential Apartments Act.

Occupation Certificates

Developers must give the Secretary at least six months' (but not more than 12 months) notice of its intention to apply for an occupation certificate under the Environmental Planning and Assessment Act 1979 (NSW). If the total construction period is expected to be less than 6 months, the notice must be made within 30 days of the commencement of building work.

Failing to submit the notice may result in:

For developers expecting to apply for an occupation certificate within six months of commencement of the Residential Apartments Act, notice must be given no later than 14 September 2020.

The Secretary can issue an order prohibiting an occupation certificate from being granted for a residential apartment building if:

Other New Enforcement Powers of the Secretary

The new powers have the potential to cause serious delays to a residential development project. Both principals and contractors of projects should carefully consider allocation of responsibility and risk with respect to compliance with the new regulations.

These new powers include to:

Where a rectification order is made, the Secretary may also recover its costs from the head contractor or developer:

Overview of the Building Practitioners Act

The majority of the Building Practitioners Act commences on 1 July 2021. The Act will initially apply to design and construction of residential buildings however it is expected that the scope will be expanded in the future to cover other types of buildings.

Who is Affected by the Building Practitioners Act?

Builders, designers, professional engineers and others involved in the design and construction of all kinds of buildings should be aware of their new obligations.

The end users of buildings such as owners and owners corporations stand to gain regulation and increased accountability of building professionals.

Registration Requirements

Building practitioners (generally head contractors), design practitioners, professional engineers and specialist practitioners will all be required to be registered. It is a condition of registration that the practitioner maintain adequate insurance to cover the practitioner's work.

The Secretary is given broad powers to take disciplinary action against a registered practitioner, including:

Directors of registered companies have a personal obligation to report conduct of the company (or a registered individual doing work for the company) that constitutes grounds for taking disciplinary action, such as:

Regulated Designs

In general, the Building Practitioners Act requires registered design practitioners to provide design declarations for certain design work. Registered building practitioners must provide compliance declarations for building work they carry out in relation to regulated designs.

A design practitioner must provide a compliance declaration to a person when the practitioner provides that person with a regulated design. A regulated design is a design that is:

building practitioner is prohibited from carrying out any building work for which a regulated design is to be used unless a compliance declaration has been issued which declares that the design complies with the Building Code of Australia.

A building practitioner must take all reasonable steps to ensure that building work subject to a regulated design is carried out in accordance with the design and complies with the Building Code of Australia. However, it is a defence if the building work was done in accordance with design compliance direction provided by a registered design practitioner.

Duty of Care

Who owes the duty of care?

Any person carrying out construction work on a residential building owes a duty to exercise reasonable care to avoid economic loss caused by building defects (such as costs to rectify defects).

This will include:

Parties cannot contract out of the statutory duty of care.

Who benefits from the duty of care?

The duty of care will be owed to current and future owners of the land.

What buildings does the duty of care apply to?

The duty of care applies to all residential buildings where economic loss:

Scope of the duty of care

The duty of care will extend to any economic loss suffered in rectifying defects or any damage caused by those defects that are the subject of a person's failure to exercise reasonable care.

This is a significant change to the current state of the law in NSW.

The High Court had previously found that consulting engineers did not owe a duty of care to subsequent owners for defects in the foundations of a building complex. The new statutory duty of care has in effect overturned this decision by ensuring that engineers (and all building practitioners) will now owe a duty of care to subsequent owners.

Home Building Act

The duty of care is additional to the statutory warranties of the Home Building Act 1989 (NSW). In some instances, warranty defect claims previously excluded due to expiry of the limitation period may now be made under the new statutory duty of care.
