If you are building a new home in Sydney or Melbourne, one of the smartest financial decisions you can make is to hire an independent inspector at each construction stage. But how much do these inspections actually cost, and what affects the price? This guide covers per-stage fees, full package pricing, how Sydney and Melbourne compare, and why the cost of inspections is a fraction of what you could lose without them.
What Are Construction Stage Inspections?
Construction stage inspections are independent assessments carried out at key milestones during a residential build. A licensed third-party inspector visits your site at each stage to check that the work complies with the approved plans, the National Construction Code (NCC), relevant Australian Standards, and your building contract.
The five standard stages are:
- Slab or base stage (before the concrete slab is poured or shortly after)
- Frame stage (after structural framing is complete)
- Lock-up stage (roof on, windows and external doors installed)
- Fixing or pre-plaster stage (internal linings, wet area waterproofing, cabinetry)
- Pre-handover or practical completion inspection (final walkthrough before settlement)
Each inspection results in a detailed report with photographs, defect descriptions, and references to the relevant codes or standards.
Per-Stage Inspection Costs
Individual stage inspections in Sydney and Melbourne generally fall within a consistent price range. The table below shows typical costs for each stage.
| Typical Cost | Notes | |
|---|---|---|
| Slab / Base Stage | $350 to $500 | Foundation work is critical and often the most detailed inspection |
| Frame Stage | $300 to $450 | Covers structural framing, bracing, tie-downs, and openings |
| Lock-Up Stage | $300 to $450 | Roof, cladding, windows, doors, and rough-in services |
| Fixing Stage | $300 to $450 | Internal linings, waterproofing, cabinetry, and tiling |
| Pre-Handover / PCI | $350 to $500 | Comprehensive final check covering all finishes and compliance |
Prices are in Australian dollars and are indicative as of early 2026. Actual costs vary based on the factors described below.
Full Package Pricing
Most inspection companies, including Owner Inspections, offer a discounted package when you book all five stages together. A full five-stage package in Sydney or Melbourne typically costs between $1,500 and $2,500.
Booking a package offers two benefits. First, you save money compared to booking each stage individually. Second, you get continuity. The same inspector (or the same team) follows your build from start to finish, which means they understand the history of your project and can track whether earlier defects were properly rectified.
A full package of five stage inspections generally costs less than 0.5% of the total build cost on a standard residential project. For context, rectifying a single structural defect found after handover can cost $10,000 to $50,000 or more.
Sydney vs Melbourne Pricing
Pricing between Sydney and Melbourne is broadly similar, though there are some differences driven by local market conditions.
Sydney inspection costs tend to sit at the higher end of the range. This reflects higher operating costs in the Sydney market, including travel times across the greater Sydney region. Sites in outer growth corridors such as the North West, South West, and Macarthur areas may attract a travel surcharge depending on the inspection provider.
Melbourne inspection costs are comparable but can be slightly lower in some cases, particularly for properties in the inner and middle ring suburbs where travel times are shorter. However, Melbourne's outer growth areas, including suburbs in the Casey, Wyndham, and Whittlesea corridors, may also attract additional travel fees.
In both cities, the core inspection fee is similar. The main price differences come down to property size, travel distance, and the complexity of the build.
What Affects the Price?
Several factors influence the cost of a construction stage inspection.
- Property size: Larger homes take longer to inspect. A single-storey three-bedroom home will cost less to inspect than a two-storey five-bedroom home with a separate garage
- Build complexity: Custom designs, split levels, multiple wet areas, or unusual construction methods require more time and expertise
- Location and travel: Sites in outer suburbs or regional areas may incur a travel surcharge
- Inspector qualifications: Inspectors with higher credentials, specialist experience, or expert witness capability may charge more, but the quality of their reporting reflects this
- Report detail: Some providers deliver a basic checklist. Others provide comprehensive photographic reports with code references and defect severity ratings. The more detailed report is worth the difference in cost
The Value Argument: Inspection Cost vs Build Cost
The average cost of building a new home in Sydney or Melbourne in 2026 ranges from approximately $350,000 to $700,000 or more, depending on the size, location, and specification of the home. A full set of stage inspections at $1,500 to $2,500 represents roughly 0.3% to 0.7% of that total build cost.
To put this in perspective, consider the typical cost of rectifying common defects discovered after handover:
| Rectification Cost | |
|---|---|
| Waterproofing failure in bathroom | $12,000 to $25,000 |
| Structural frame defect | $8,000 to $20,000 |
| Slab cracking from poor reinforcement | $10,000 to $50,000+ |
| Drainage and stormwater issues | $5,000 to $15,000 |
| Roof flashing and leak defects | $3,000 to $12,000 |
A single defect caught during a $400 stage inspection can save you $10,000 or more. When viewed against the total build cost, stage inspections are one of the most cost-effective investments you can make during construction.
What Is Included in the Fee?
When you pay for a construction stage inspection, you should expect the following to be included:
- A thorough on-site inspection by a licensed building inspector
- A detailed written report, typically delivered within 24 to 48 hours
- Photographs documenting all identified defects and areas of concern
- References to the relevant Australian Standards, NCC clauses, or building contract specifications
- A summary of defects categorised by severity
- Recommendations for rectification
Some providers also include a follow-up phone call to walk you through the report findings. Ask about this when requesting a quote.
How to Get Accurate Pricing
The best way to get an accurate price for your project is to contact the inspection company with the following details:
- The property address or suburb
- The type of build (single storey, double storey, duplex, townhouse)
- The approximate floor area
- Whether you need individual stages or a full package
- Your builder and the approximate construction timeline
This allows the provider to give you a fixed quote rather than a vague range.
Key Takeaways
- Individual construction stage inspections in Sydney and Melbourne typically cost between $300 and $500 per stage.
- A full five-stage package generally ranges from $1,500 to $2,500, with a discount compared to booking individually.

Frequently Asked Questions
QHow much does a single construction stage inspection cost in Sydney?
A single construction stage inspection in Sydney typically costs between $300 and $500, depending on the stage, the size of the property, and the location within greater Sydney. Slab and pre-handover inspections tend to be at the higher end of the range due to the level of detail involved. Properties in outer growth areas may attract a small travel surcharge.
QIs it cheaper to book all five stages as a package?
Yes. Most inspection companies offer a discounted rate when you book all five construction stages as a package. The total package cost is typically 10% to 20% less than the combined cost of booking each stage individually. Packages also provide continuity, as the same inspector follows your build throughout, which improves defect tracking and accountability.
QAre construction stage inspections worth the cost?
Absolutely. The cost of a full inspection package is a fraction of the total build cost, and catching even one significant defect during construction can save you $10,000 or more in rectification expenses. Beyond the financial benefit, inspections give you documented evidence of construction quality at every stage, which is valuable for warranty claims and future resale.
QDo inspection costs differ between Sydney and Melbourne?
The core inspection fees are broadly similar in both cities. Sydney prices tend to sit slightly higher due to greater operating costs and longer travel times across the metropolitan area. Melbourne can be marginally lower for inner and middle ring suburbs but comparable for properties in outer growth corridors. The main price drivers in both cities are property size, build complexity, and travel distance.
QWhat should I look for when comparing inspection prices?
Do not choose an inspector based on price alone. Look for a licensed inspector who provides detailed photographic reports with references to Australian Standards and the NCC. Check that the fee includes a comprehensive written report and not just a basic checklist. Ask about the inspector's qualifications, experience, and whether they carry professional indemnity insurance. A cheaper inspection that misses a critical defect costs you far more in the long run.
