Frequently Asked Questions
What do façade remediation works involve?
A Class 2 Registered Building Practitioner is authorised under the NSW Design & Building Practitioners Act to carry out and oversee regulated building work on Class 2 buildings.
This registration confirms the practitioner:
• Is appropriately qualified and experienced with 5+ years experience
• Is legally permitted to deliver regulated Class 2 work
• Can provide required declared designs and compliance declarations• Carries accountability for compliance under the DBP Act
When is a Class 2 Registered Building Practitioner required?
A registered building practitioner is required whenever regulated building work is carried out on a Class 2 building.
This commonly includes:
• Structural works
• Façade systems
• Waterproofing systems
• Fire-related building elements
• Other critical building components
Using an unregistered practitioner for regulated work exposes the project to compliance and approval risk.
What happens if a builder is not registered for Class 2 work?
If Class 2 building work proceeds without a registered practitioner, owners may be exposed to:
• Building defects
• Compliance failures
• Liability and disputes
• Warranty issues
• Costly rectification after completion
Missing or invalid declarations can also delay approvals and create uncertainty if issues arise later.
What role does a registered building practitioner play during the project?
The registered building practitioner is responsible for ensuring regulated building work is:
• Properly designed and documented
• Coordinated and executed in line with declared designs
• Delivered in accordance with statutory requirements
• Raise any design discrepancies during construction
This creates a clear and auditable compliance pathway from design through to construction.
How does using a registered practitioner reduce defect risk?
Registered practitioners are required to work from declared designs provided by registered designer such as structural, civil and waterproofing engineers.
This reduces reliance on assumptions and helps prevent:
• Design and construction mismatches
• Poor coordination of regulated elements
• Defects that emerge after completion
• Rework and rectification costs
Does registration affect insurance and statutory warranties?
Yes. Proper registration and lawful delivery of regulated building work help protect:
• Statutory warranties
• Insurance responses
• Recovery options if defects occur
Where work is carried out without required registration, warranty claims may be challenged and insurance outcomes can be limited.
Who typically engages a Class 2 Registered Building Practitioner?
Class 2 Registered Building Practitioners are commonly engaged by:
• Owners Corporations
• Strata and Building Managers
• Developers
• Asset Managers
• Project Managers
Early engagement improves compliance certainty and project outcomes.
