Strata Building Bond Claim Process NSW: A Step-by-Step Guide
How NSW's Strata Building Bond and Inspections Scheme works, what owners corporations must do to preserve their rights, and how to navigate a bond claim.

The Strata Building Bond and Inspections Scheme requires NSW developers to lodge 2% of the construction contract price with the NSW Government before a new class 2 building commences. That money is held in trust for 24 months from practical completion. If defects are found and the builder does not rectify them, the owners corporation can access the bond funds. It is the most significant consumer protection mechanism for purchasers in new strata buildings, and most owners corporations do not use it effectively.
What is the SBBIS?
The Strata Building Bond and Inspections Scheme (SBBIS) was established by the Strata Schemes Management Act 2015 (NSW) and the associated Regulations. It operates in four stages that the NSW Government identifies as Stage 1 (bond lodgement), Stage 2 (first inspection), Stage 3 (defect rectification), and Stage 4 (bond release or claim).
The scheme applies to residential and mixed-use strata buildings that are class 2 under the National Construction Code (i.e., residential apartment buildings) where the contract for building work was entered into after 1 January 2018. It does not apply to buildings where the contract predates the scheme's commencement.
The bond amount is 2% of the contract price for the building work. On a $20 million construction contract, the bond is $400,000. On a $50 million contract, the bond is $1,000,000. This is a material sum, and it is the owners corporation's right to claim it if the builder does not rectify defects.
The Four Stages in Detail
Stage 1: Bond Lodgement
Before the developer can obtain a construction certificate or complying development certificate for a class 2 building, the developer must lodge the bond with NSW Government. The lodgement is made through the NSW Planning Portal. Failure to lodge the bond before construction commences is a breach of the SSMA.
The bond is calculated on the contract price at the time of lodgement. If the contract price is subsequently varied, the developer must notify NSW Government and adjust the bond accordingly.
What the owners corporation should do at Stage 1: At handover, request confirmation from the developer that the bond has been lodged and obtain the bond reference number. This is public information that you are entitled to. Record it in the strata roll.
Stage 2: The Independent Inspection (15-18 Months)
The critical window in the SBBIS is the inspection that occurs between 15 and 18 months after the date of the occupation certificate. The Building Commission NSW appoints an independent inspector from its accredited pool.
The inspection must occur within this specific window. A developer who attempts to delay or obstruct the inspection is in breach of the scheme. The owners corporation should monitor the timeline and contact the Building Commission NSW if the inspection is not scheduled by month 14.
The inspector's brief is to identify "defects" as defined by the Regulations. This includes:
- Waterproofing failures - the single most common category. Balcony tile delamination, bathroom water egress, roof membrane failures, and planter box leaks are the most frequently identified waterproofing defects.
- Fire safety - non-compliance with the Building Code of Australia, incorrect sprinkler head coverage, passive fire protection failures (penetrations in fire-rated walls), fire door issues.
- Balustrades and barriers - non-compliance with AS 1170 loading requirements, inadequate fixings, incorrect height.
- Facade and cladding - cracks in render, movement at control joints, inadequate weatherproofing at windows and external doors.
- Services - hydraulic systems not functioning to design, mechanical ventilation deficiencies, drainage inadequacies.
- Structural - though less common at 15-18 months, structural defects are the highest priority items and should be escalated immediately.
What the owners corporation should do before Stage 2: Commission an independent defect report from a registered building consultant or engineer before the SBBIS inspection. This report documents defects observed since handover and gives the inspector additional evidence to examine. An owners corporation that arrives at a Stage 2 inspection with only the developer's handover records is in a weaker position than one with an independent report. See our building defect report guide for what a comprehensive report contains.
The owners corporation should also prepare a defect log documenting every issue reported by lot owners and the strata committee since the building was occupied. Dates of notification, photographs, and correspondence with the builder should all be compiled.
Stage 3: Defect Rectification
Following the Stage 2 inspection, the inspector produces a defects report. The developer and builder receive notice of the identified defects and are given an opportunity to rectify them. The Regulations set out the timeframes for rectification.
Critical defects (as defined - safety-related, structural, or affecting habitability) require urgent rectification. The owners corporation should not accept a builder's programme that extends critical defect rectification beyond what is genuinely necessary to mobilise trade contractors.
Other defects are rectified within the builder's agreed programme. The owners corporation has the right to inspect rectification works and confirm completion before accepting that a defect has been remedied.
Do not accept a builder's assertion that a defect has been "repaired" without physical inspection. Common examples of inadequate rectification include:
- Applying sealant over a failing waterproofing membrane rather than replacing the membrane
- Tile re-grouting without addressing the substrate leak
- Painting over concrete cracks without investigating the cause
- Replacing a fire door but not addressing the non-compliant installation
Ensure that any rectification work is documented: photographs before and after, the methodology used, and the name of the contractor. If the rectification involves regulated design work (any structural or fire-safety intervention), the contractor must be registered under the DBP Act. See our DBP Act guide for the registration requirements.
Stage 4: Bond Release or Claim
At the end of the 24-month period, the bond is either released to the developer or, if defects have not been rectified satisfactorily, the owners corporation can apply for the bond funds to be used for rectification.
If defects have been satisfactorily rectified: The developer applies for bond release. The owners corporation receives notice and has 14 days to object. If there are outstanding defects, the owners corporation must object with evidence before the 14-day period expires. Silence is treated as consent to bond release.
If defects have not been rectified: The owners corporation applies to access the bond funds. The application must be supported by:
- Evidence of the defects (the SBBIS inspection report plus any independent report)
- Evidence that the developer was notified and given an opportunity to rectify
- Quotations for independent rectification
- A formal application to NSW Government
Bond funds are released to the owners corporation to engage an independent contractor for rectification. Any surplus bond funds are returned to the developer.
The 14-Day Objection Window is Critical
The most common failure we observe in SBBIS cases is owners corporations missing the 14-day objection window at Stage 4. If the developer applies for bond release and the owners corporation does not object within 14 days, the bond is released and the opportunity is gone.
Mark this date. Set a calendar reminder 10 months after the occupation certificate date (well ahead of the 24-month expiry) so the committee actively monitors the bond status.
Common Defects Identified at SBBIS Inspections
Based on Building Commission NSW data and our own remedial work across Sydney, the following defects are most frequently identified at SBBIS inspections:
| Defect Category | Frequency | Typical Rectification Cost |
|---|---|---|
| Waterproofing - balconies | Very high | $300 - $800 per m2 |
| Waterproofing - bathrooms | High | $150 - $400 per m2 |
| Fire system non-compliance | High | Variable - $500 to $50,000+ |
| Balustrade non-compliance | Medium | $500 - $2,500 per linear metre |
| Facade / cladding defects | Medium | $200 - $600 per m2 |
| Hydraulic services | Medium | $5,000 - $100,000+ |
| Structural | Low | $10,000 - $500,000+ |
For waterproofing specifically, the AS 4654 waterproofing standard is the benchmark against which balcony and external waterproofing is assessed. Owners corporations should understand this standard when reviewing the SBBIS inspector's findings.
What Happens After the Bond Period
Once the 24-month SBBIS period expires, the scheme's protections end. The owners corporation's remedies shift to:
- The Home Building Act 1989 (NSW) for "major defects" (6-year limitation from awareness, 2-year limitation for other defects)
- The Design and Building Practitioners Act 2020 for negligent designs
- NCAT proceedings against the developer or builder
These pathways remain available, but they are more costly and time-consuming than the SBBIS. The scheme's 24-month window exists precisely because it is faster and cheaper. Use it.
For the underlying obligation on the owners corporation once the bond period has expired, see Section 106 in plain English. For the digital register obligations that apply from the date of completion, read digital defects register requirements.
Our team has carried out rectification works on newly completed buildings across Pyrmont, Zetland, and Darling Point, including under SBBIS-funded programmes. The quality of defect documentation at the time of instruction directly determines how efficiently rectification can be completed. See our project history or contact us to discuss a specific building.

The Bottom Line
The Strata Building Bond and Inspections Scheme holds up to 2% of the construction price in trust for 24 months. For a $30 million building, that is $600,000 available for defect rectification. Most owners corporations do not access it because they miss the notification windows, accept inadequate rectification, or fail to commission an independent report before the Stage 2 inspection. The process is designed to protect purchasers. Owners corporations that actively engage with it recover funds that would otherwise be lost.
