Victoria’s building compliance landscape has undergone significant transformation in 2025, with the establishment of the Building and Plumbing Commission (BPC) on 1 July 2025. For property developers working on multi-unit projects in Melbourne’s Eastern Suburbs, understanding the new compliance certificate requirements isn’t just about ticking boxes—it’s about protecting your investment and avoiding costly delays.
The building compliance certificate (formally known as a Certificate of Final Inspection or Statement of Compliance) verifies that completed building work complies with regulatory requirements under the Building Act 1993 and Building Regulations 2018. With the BPC’s expanded powers now extending up to 10 years post-occupancy and new developer bond requirements for buildings over three storeys, compliance documentation has become more critical than ever for developers in Whitehorse, Boroondara, Manningham, Monash, Knox, and Maroondah.
This guide outlines the current compliance certificate process, new regulatory requirements under the Building Legislation Amendment (Buyer Protections) Act 2025, and practical strategies for developers navigating Victoria’s strengthened building system.
Understanding Building Compliance Certificates in Victoria’s New Regulatory Framework
A building compliance certificate serves as formal verification that construction work complies with the approved building permit, relevant Australian Standards, and the National Construction Code (NCC). In Victoria, this documentation is issued by the relevant building surveyor (RBS) who oversaw the project, not by the council or the BPC directly.
The certificate confirms several critical compliance points:
- All mandatory notification stages were completed and inspected
- Building work aligns with approved plans and specifications
- Construction meets NCC 2022 requirements (mandatory from 1 May 2024)
- Essential safety measures are installed and operational
- Required documentation is complete for the building manual
For developers, the compliance certificate is essential for obtaining an occupancy permit, settling off-the-plan contracts, and registering plans of subdivision. Under the new BPC regime, incomplete or inaccurate compliance documentation can trigger rectification orders and prevent subdivision registration—potentially delaying project completion by 6-12 months.
The BPC’s enhanced enforcement powers mean that compliance issues discovered after occupancy can now result in rectification orders issued directly to developers of residential apartment buildings, not just builders. This represents a fundamental shift in accountability that developers must factor into their project risk management.
The Building and Plumbing Commission: What Changed on 1 July 2025
The establishment of the BPC consolidated three separate agencies—the former building authority, Domestic Building Dispute Resolution Victoria (DBDRV), and the domestic building insurance function of the Victorian Managed Insurance Authority (VMIA)—into a single integrated regulator. This restructure directly impacts how compliance certificates are issued, verified, and enforced.
Key changes affecting developers include:
- Extended rectification powers: The BPC can now issue rectification orders for up to 10 years after an occupancy permit is issued, compared to the previous limitation of only pre-occupancy enforcement
- Retrospective application: These powers apply to building work completed before 1 July 2025, meaning existing projects may face scrutiny under the new regime
- Developer accountability: For residential apartment buildings, rectification orders can be issued against developers in addition to builders and subcontractors
- Mandatory pre-occupancy notifications: Developers of buildings over three storeys must notify the BPC 6-12 months before applying for an occupancy permit
The BPC has indicated that enforcement will focus particularly on Class 2 buildings (apartments), with inspection blitzes targeting waterproofing, structural compliance, and fire safety systems. Developers should anticipate increased scrutiny during the mandatory notification stages that precede compliance certificate issuance.
Penalties for non-compliance have increased substantially, with fines up to 2,500 penalty units (approximately $500,000) for failures related to developer bonds, mandatory notifications, or rectification order non-compliance. This represents a significant financial risk that must be factored into project budgets and timelines.
Developer Bond Requirements for Buildings Over Three Storeys
One of the most significant changes under the Building Legislation Amendment (Buyer Protections) Act 2025 is the mandatory developer bond scheme for residential apartment buildings exceeding three storeys. This requirement directly impacts the compliance certificate process and project cash flow.
The developer bond operates as follows:
- Bond amount: 2% of total build cost (defined as the estimated total cost of building work for the residential apartment building)
- Timing: Must be provided to the BPC as a pre-condition to applying for an occupancy permit
- Duration: Held by the BPC for two years after the occupancy permit is issued
- Purpose: Ensures funds are available to rectify defects discovered post-occupancy
For a typical $15M apartment development in Box Hill or Glen Waverley, this may translate to approximately $300,000 in bond security that must be arranged before the occupancy permit application. This capital requirement has significant implications for project financing and settlement timing.
Developers must provide mandatory notification to the BPC between 6-12 months before the anticipated occupancy permit application date. Any changes to this timeline must be notified within five business days, with penalties for non-compliance reaching $500,000. This notification requirement should be integrated into project schedules from the outset.
The regulations governing bond implementation are still being finalised through public consultation. Key questions remain about whether developers can transfer bond responsibility to builders or engage third-party providers. Developers should monitor BPC guidance closely as these details are confirmed throughout 2025-26.
Mandatory Notification Stages and Inspection Requirements
The compliance certificate process relies on successful completion of mandatory notification stages, where the RBS inspects critical construction phases before work is concealed. The Building Regulations 2018 prescribe specific stages when the builder must notify the RBS for inspection.
Standard mandatory notification stages include:
- Footing stage: Before concrete is poured for footings and slabs
- Framework stage: Before any part of the framework is covered (new requirement from June 2025)
- Waterproofing stage: Before wet area waterproofing is covered (new requirement from June 2025)
- Drainage stage: Before stormwater and sewer drainage is covered (see plumbing regulations for detailed requirements)
- Final stage: When all building work is complete
The Building Amendment (Building Manuals and Mandatory Inspections) Regulations 2025 introduced two additional mandatory stages—framework and waterproofing inspections—reflecting increased focus on structural integrity and water ingress prevention. These changes came into effect on 30 June 2025.
For Class 2 buildings, the BPC has implemented enhanced inspection protocols following widespread waterproofing failures in apartment developments. Developers should expect more detailed scrutiny at each mandatory stage, with RBS professionals facing increased liability for missed non-compliances.
The BPC’s inspection blitz program, which commenced in late 2024, has resulted in over 1,000 site inspections with a particular focus on unregistered trades and non-compliant work. Compliance rates have improved from approximately 60% to 85% as of mid-2025, but enforcement actions have increased proportionally. Developers should ensure all subcontractors hold appropriate registrations and work within approved plans.
Building Manuals: New Documentation Requirements
A significant addition to the compliance framework is the mandatory building manual requirement for new buildings. This centralised repository of construction documentation must be created, maintained, and updated throughout the building’s lifecycle.
The building manual must include:
- Copy of the planning permit application and accompanying documents
- Approved building permit and any amendments
- Documents provided to council under section 30(1A) of the Building Act 1993
- Protection work notices and accompanying documentation
- Occupancy permit application and issued permit
- Certificate of Final Inspection
- Records of subsequent building work, plumbing work, and electrical work
- Essential safety measures maintenance records
- Pool barrier compliance certificates (see pool regulations for requirements)
For developers, the building manual requirement introduces new obligations at the occupancy permit stage. A draft building manual must accompany the occupancy permit application, with the approved manual provided to the BPC within 28 days of the occupancy permit being attached to it.
The owner or owners corporation becomes responsible for maintaining and updating the building manual after settlement. However, developers must ensure the initial manual is comprehensive and accurate, as deficiencies can delay occupancy permit issuance and settlement.
This documentation requirement aligns with the BPC’s enhanced enforcement powers, providing a clear record of construction decisions and compliance verification that can be referenced if defects emerge within the 10-year rectification period. Developers should treat building manual compilation as a critical project deliverable, not an administrative afterthought.
The Compliance Certificate Process: Step-by-Step for Developers
Obtaining a building compliance certificate involves a structured process that begins well before construction completion. Understanding each stage helps developers avoid delays and compliance issues.
Step 1: Pre-Construction Planning (Weeks 1-4)
Engage an RBS early in the design phase to review plans for compliance with NCC 2022 requirements and local planning scheme provisions. For developments in Whitehorse or Boroondara, this includes verification that designs meet ResCode standards and any local variations to state requirements. Consider engaging an architect or building designer with experience in your council area.
Step 2: Building Permit Application (Weeks 4-8)
Submit the building permit application with complete documentation. The RBS must be satisfied that proposed work complies with the Building Act 1993 and Building Regulations 2018. Incomplete applications are a common cause of delays—the BPC’s new Class 2 Practice Guide sets detailed documentation standards that must be met. Ensure your planning drawings are comprehensive and coordinated.
Step 3: Mandatory Notification Stages (Throughout Construction)
Notify the RBS at each mandatory stage and allow adequate time for inspection. The builder must not proceed to the next stage until the RBS confirms compliance. For the new framework and waterproofing stages, this may require 48-72 hours’ notice to accommodate RBS scheduling.
Step 4: Developer Bond Notification (6-12 Months Before Completion)
For buildings over three storeys, notify the BPC of the intended occupancy permit application date. This notification must occur within the 6-12 month window, with updates provided within five business days if the timeline changes. Coordinate this notification with your project manager and builder to ensure accuracy.
Step 5: Final Inspection and Certificate of Final Inspection (Weeks 1-2 Before Occupancy)
Request final inspection from the RBS once all building work is complete. The RBS will verify that work complies with the approved permit and issue a Certificate of Final Inspection if satisfied. This certificate is a prerequisite for the occupancy permit application.
Step 6: Building Manual Compilation (Concurrent with Final Inspection)
Compile the draft building manual with all required documentation. This must accompany the occupancy permit application and should be reviewed by the RBS for completeness before submission.
Step 7: Developer Bond Provision (Before Occupancy Permit Application)
Provide the 2% developer bond to the BPC before submitting the occupancy permit application. Ensure the bond arrangement complies with BPC requirements (specific regulations pending as of late 2025).
Step 8: Occupancy Permit Application and Issuance (Weeks 1-2)
Submit the occupancy permit application with the Certificate of Final Inspection, draft building manual, and evidence of developer bond provision. The RBS will issue the occupancy permit if satisfied all requirements are met.
Step 9: Post-Occupancy Compliance (2-Year Bond Period)
Maintain records of any defect reports or rectification work during the two-year bond period. The BPC can issue rectification orders during this period, with the developer bond available to fund required work if the builder fails to comply.
Common Compliance Issues and How to Avoid Them
Based on BPC enforcement data and industry experience, several compliance issues consistently delay certificate issuance or trigger post-occupancy rectification orders.
Incomplete Documentation at Mandatory Stages
The most frequent issue is inadequate documentation at mandatory notification stages. The BPC’s Class 2 Practice Guide now requires detailed design documentation including architectural, fire safety, and structural engineering information. RBS professionals are rejecting applications with missing details, as they may face liability if defects later emerge from inadequate review.
Solution: Engage design professionals early and ensure they provide comprehensive documentation that addresses all Practice Guide requirements. Budget for additional design fees if necessary—incomplete documentation typically costs far more in delays than thorough upfront preparation.
Waterproofing Non-Compliance
Waterproofing failures in wet areas and balconies have been a primary focus of BPC enforcement. The new mandatory waterproofing inspection stage reflects this concern. Common issues include incorrect membrane installation, inadequate fall to drains, and missing or improperly installed penetration seals.
Solution: Engage a specialist waterproofing consultant for design and inspection. Ensure the waterproofing contractor holds appropriate registration and provides detailed installation records for the building manual. Consider third-party waterproofing certification to reduce risk.
Essential Safety Measures Non-Compliance
Fire safety systems, emergency lighting, and exit signage must be installed and operational before occupancy permit issuance. The BPC has increased scrutiny of essential safety measures following several high-profile building failures.
Solution: Engage a fire safety engineer early in design and ensure all essential safety measures are tested and certified before final inspection. Obtain annual essential safety measures reports from a qualified technician and include these in the building manual.
Unregistered Subcontractors
The BPC’s inspection blitz has identified widespread use of unregistered trades, particularly for plumbing, electrical, and waterproofing work. Penalties have doubled from 2024 levels, with fines reaching $50,000 for individuals and $250,000 for companies.
Solution: Verify all subcontractor registrations before work commences and maintain a register of current registrations throughout the project. Include registration verification as a condition in subcontract agreements.
Variations Not Documented
Construction variations that deviate from approved plans must be documented through permit amendments. Undocumented variations discovered during final inspection will delay certificate issuance and may trigger enforcement action.
Solution: Implement a formal variation management process that includes RBS review and permit amendment where required. Budget for amendment fees and allow 2-4 weeks for RBS processing.
NCC 2022 Compliance Requirements
The National Construction Code 2022 became fully mandatory in Victoria on 1 May 2024, introducing significant changes to energy efficiency, accessibility, and construction standards. These requirements directly impact compliance certificate issuance.
Key NCC 2022 changes affecting developers:
- 7-star energy efficiency: Class 1 and Class 2 buildings must achieve minimum 7-star NatHERS rating (increased from 6-star)
- Whole-of-home performance: New requirements for heating, cooling, and hot water system efficiency
- Accessible housing: Mandatory accessibility features including step-free entries, wider doorways, and accessible bathrooms
- Condensation management: New standards to prevent condensation-related building damage
- Waterproofing and weatherproofing: Updated standards for external walls and wet areas
For apartment developments in Melbourne’s Eastern Suburbs, the 7-star energy efficiency requirement typically necessitates improved glazing performance, enhanced insulation, and careful attention to thermal bridging. These measures may add approximately 1-2% to construction costs but are mandatory for compliance certificate issuance.
The accessible housing requirements apply to all new Class 2 buildings, with specific provisions for step-free entries, circulation spaces, and bathroom layouts. Developers should engage an accessibility consultant during design to ensure compliance, as retrofitting accessibility features post-construction is significantly more expensive.
RBS professionals are required to verify NCC 2022 compliance before issuing building permits and compliance certificates. The BPC has provided detailed guidance on evidence required to demonstrate compliance, including NatHERS certificates, accessibility checklists, and waterproofing design specifications.
Council-Specific Compliance Considerations
While building compliance certificates are issued by the RBS rather than councils, local variations to state standards can affect the compliance process. Developers working across Melbourne’s Eastern Suburbs should understand council-specific requirements.
City of Whitehorse
Whitehorse maintains local variations for street setbacks in certain residential zones, requiring greater setbacks than state standards in heritage overlay areas. The council’s planning scheme also includes specific requirements for apartment developments exceeding four storeys, which may affect building permit applications. Review planning permit timelines for Whitehorse to coordinate building permit applications.
City of Boroondara
Boroondara has extensive heritage overlays affecting approximately 40% of the municipality. Building permit applications in heritage areas require additional documentation demonstrating heritage impact assessment. The RBS must consider heritage compliance alongside building code requirements. Understanding neighbourhood character requirements is essential for heritage areas.
Manningham City Council
Manningham’s planning scheme includes specific provisions for developments in bushfire-prone areas, particularly in Warrandyte and Wonga Park. Building permits in these areas require Bushfire Attack Level (BAL) assessments and construction to AS 3959 standards, which the RBS must verify before issuing compliance certificates.
City of Monash
Monash has implemented local variations to private open space requirements in certain residential zones, requiring larger private open space areas than state standards. The RBS must verify compliance with these local variations during the building permit assessment.
Knox City Council
Knox maintains specific requirements for developments in the Foothills and Dandenong Ranges areas, including enhanced landscape provisions and vegetation protection requirements. Building permits must demonstrate compliance with these provisions before issuance.
Maroondah City Council
Maroondah’s planning scheme includes specific provisions for apartment developments in activity centres, with local variations to building height and setback requirements. The RBS must consider these provisions during building permit assessment.
First Resort Insurance Scheme Changes
The Building Legislation Amendment (Buyer Protections) Act 2025 introduced a new first resort warranty scheme for domestic building work up to three storeys, replacing the previous domestic building insurance (DBI) arrangements. This change affects how compliance certificates interact with consumer protections.
Under the new scheme:
- Insurance is triggered when a builder fails to comply with a BPC rectification order, rather than requiring builder insolvency, disappearance, or death
- Coverage extends to defects discovered within the warranty period, even if the occupancy permit has been issued
- The scheme is administered by the BPC rather than the VMIA, streamlining claims processing
- Builders must contribute a levy (currently under consultation) to fund the scheme
For developers, this change means that compliance certificate issuance no longer provides complete protection from defect liability. The BPC can issue rectification orders for up to 10 years post-occupancy, and the first resort scheme provides building owners with an additional avenue for defect rectification if builders fail to comply.
The scheme does not apply to speculative building work where the building owner is the builder or an associate, or where the building owner has contracted for construction of three or more homes. This exclusion means developers undertaking speculative apartment developments cannot access the scheme and must rely on contractual warranties and builder performance bonds. For more on this distinction, see our guide to owner builder requirements.
Developers should review their construction contracts to ensure adequate defect liability provisions and performance securities that align with the 10-year rectification order period. Standard 12-month defect liability periods may be insufficient given the BPC’s extended enforcement powers.
Rectification Orders and Post-Occupancy Enforcement
The BPC’s power to issue rectification orders for up to 10 years after occupancy permit issuance represents a fundamental shift in building compliance enforcement. Understanding how these orders interact with compliance certificates is essential for risk management.
Rectification orders can be issued for:
- Defective building work that fails to comply with the Building Act 1993 or Building Regulations 2018
- Incomplete building work that was required under the building permit
- Non-compliant building work that deviates from approved plans without authorisation
For residential apartment buildings, rectification orders can be issued against developers in addition to builders and subcontractors. This joint liability means that even if the builder is responsible for defective work, the developer may face enforcement action if the builder fails to rectify the issue. For guidance on managing these situations, see our article on construction problems with builders.
The BPC can apply to the Victorian Civil and Administrative Tribunal (VCAT) for extensions beyond the 10-year limit in exceptional circumstances, such as where defects were deliberately concealed or where serious safety risks are identified. This creates potential long-tail liability that developers must consider in project structuring and insurance arrangements.
Penalties for non-compliance with rectification orders reach 2,500 penalty units (approximately $500,000), with additional penalties for each day of continued non-compliance. The BPC can also prevent developers from applying for occupancy permits or registering plans of subdivision on other projects until rectification orders are satisfied.
Developers should implement robust quality assurance processes during construction and maintain comprehensive project records for at least 10 years post-occupancy. Consider engaging independent building consultants for critical construction stages to provide third-party verification of compliance.
Practical Strategies for Developers
Navigating Victoria’s strengthened building compliance framework requires proactive planning and risk management. Based on extensive experience delivering residential projects across Melbourne’s Eastern Suburbs, several strategies consistently improve compliance outcomes.
Engage the RBS Early
Involve the RBS during design development, not just at building permit application. Early engagement identifies compliance issues when design changes are least expensive and allows the RBS to provide guidance on documentation requirements. Budget for pre-application meetings and preliminary compliance reviews.
Implement Staged Quality Assurance
Establish quality assurance checkpoints aligned with mandatory notification stages. Engage independent building consultants to review work before RBS inspections, identifying and rectifying issues before they become formal non-compliances. This approach could reduce rectification costs compared to addressing issues after RBS rejection.
Maintain Comprehensive Project Records
Document all design decisions, construction variations, and compliance verifications in a centralised project management system. This documentation forms the basis of the building manual and provides evidence if rectification orders are issued post-occupancy. Digital documentation systems with cloud backup ensure records are preserved for the full 10-year rectification period.
Structure Development Agreements Appropriately
Review development agreements and construction contracts to allocate compliance responsibilities clearly. Include provisions for developer bond funding, extended defect liability periods aligned with the 10-year rectification window, and performance securities adequate to cover potential rectification costs. Consider requiring builders to maintain professional indemnity insurance for 10 years post-completion.
Budget for Compliance Costs
Factor compliance-related costs into project budgets from the outset. Typical compliance costs for a $15M apartment development may include: RBS fees ($40,000-$60,000), developer bond ($300,000), building manual compilation ($15,000-$25,000), independent quality assurance ($50,000-$80,000), and contingency for rectification work (2-3% of build cost). Underestimating these costs is a common cause of project financial stress.
Monitor Regulatory Updates
The BPC continues to release guidance and regulations throughout 2025-26 as the new framework is implemented. Subscribe to BPC updates and engage advisors who monitor regulatory changes. Regulations governing developer bond implementation, building manual requirements, and rectification order procedures are still being finalised through public consultation.
Frequently Asked Questions
What is a building compliance certificate in Victoria?
A building compliance certificate (formally a Certificate of Final Inspection) is issued by the relevant building surveyor confirming that completed building work complies with the approved building permit, Building Act 1993, Building Regulations 2018, and National Construction Code. It’s required before an occupancy permit can be issued.
How long does it take to obtain a compliance certificate?
The compliance certificate process typically takes 1-2 weeks after construction completion, provided all mandatory notification stages were completed successfully and documentation is complete. Delays commonly occur due to incomplete building manuals, outstanding rectification work, or essential safety measures non-compliance. For buildings over three storeys, allow additional time for developer bond processing.
What happens if defects are discovered after the compliance certificate is issued?
Under the Building Legislation Amendment (Buyer Protections) Act 2025, the BPC can issue rectification orders for up to 10 years after occupancy permit issuance. For residential apartment buildings, these orders can be issued against developers as well as builders. The developer bond (for buildings over three storeys) is held for two years to fund rectification if required.
Do I need a compliance certificate for renovations or extensions?
Yes, any building work requiring a building permit must be certified as compliant before an occupancy permit (or certificate of final inspection for work not requiring occupancy permits) can be issued. This applies to renovations, extensions, and alterations, not just new construction. The relevant building surveyor issues the certificate after final inspection.
How much does the developer bond cost for apartment buildings?
The developer bond is 2% of the total build cost for residential apartment buildings over three storeys. For a $15M development, this equals approximately $300,000. The bond is held by the BPC for two years after the occupancy permit is issued and is returned if no rectification orders are issued during that period.
Can I apply for an occupancy permit without a compliance certificate?
No, the Certificate of Final Inspection (compliance certificate) is a mandatory prerequisite for occupancy permit applications. The relevant building surveyor will not accept an occupancy permit application until they have inspected the completed work and issued the certificate confirming compliance with the approved building permit.
What is the building manual requirement and who is responsible for it?
The building manual is a centralised repository of all construction documentation, permits, and compliance records. A draft building manual must accompany the occupancy permit application. After settlement, the owner or owners corporation becomes responsible for maintaining and updating the manual with records of subsequent building work, maintenance, and essential safety measures testing.
Conclusion
Victoria’s building compliance framework has undergone substantial strengthening with the establishment of the Building and Plumbing Commission and implementation of the Building Legislation Amendment (Buyer Protections) Act 2025. For property developers working in Melbourne’s Eastern Suburbs, these changes introduce new obligations, extended liability periods, and increased financial requirements that must be integrated into project planning from the outset.
The building compliance certificate remains the critical gateway to occupancy permit issuance and project settlement, but the compliance process now extends well beyond certificate issuance. With the BPC’s power to issue rectification orders for up to 10 years post-occupancy and mandatory developer bonds for buildings over three storeys, developers must implement robust quality assurance processes and maintain comprehensive documentation throughout construction and beyond.
Success in this strengthened regulatory environment requires early engagement with qualified building surveyors, proactive compliance management during construction, and careful structuring of development agreements to allocate risks appropriately. Developers who treat compliance as a strategic priority rather than an administrative burden consistently achieve better project outcomes, with fewer delays, lower rectification costs, and reduced regulatory risk.
