In Australia, you have the right to arrange independent building inspections during construction. However, standard building contracts from the Housing Industry Association (HIA) and Master Builders Association (MBA) often include clauses that allow builders to charge additional fees or restrict access when homeowners engage their own inspectors. The key is adding a specific clause to your contract before signing that protects your inspection rights without penalty. This clause typically states that the builder must provide reasonable access to an independent inspector at no additional cost to the owner during normal business hours with 48 hours notice.
Most homeowners discover inspection restrictions only after signing their contract, when a builder either refuses access or demands payment ranging from $500 to $2,000 per inspection visit. This article explains exactly which paragraph to add, how to negotiate it with your builder, and what to do if your contract is already signed.
Understanding Standard Contract Clauses
Standard HIA and MBA building contracts contain clauses about site access and inspections. These clauses typically favour the builder by requiring written permission for third-party inspectors or allowing the builder to charge supervision fees.
The HIA contract often includes wording like "the builder may charge a reasonable fee for supervision of any inspection arranged by the owner". This creates a financial disincentive for independent oversight.
Common Contract Restrictions
Standard building contracts may limit your inspection rights through clauses about site access, insurance requirements, or supervision fees. Always review the entire contract before signing.
Some builders justify these fees by claiming inspectors disrupt work schedules or create insurance liability issues. However, professional building inspectors carry their own public liability insurance and work efficiently to minimise site disruption.

The Recommended Inspection Clause
The most effective contract amendment protects your right to independent inspections without giving the builder grounds to charge extra fees or delay access. Here is the recommended clause to add:
Contract Amendment Clause
"The owner reserves the right to engage an independent building inspector at any stage of construction. The builder must provide reasonable access to the inspector during normal business hours with a minimum of 48 hours written notice. The builder shall not charge any fee, supervision cost, or other amount for providing this access. The inspector must hold current public liability insurance of at least $10 million and provide proof of this insurance to the builder upon request."
This clause achieves several objectives. It establishes your legal right to inspections, defines reasonable notice periods, prevents fee charging, and addresses the builder's legitimate insurance concerns.
Some builders may counter-propose limiting inspections to specific stages only. If you must compromise, insist on access at a minimum during slab pour, frame stage, waterproofing, and pre-handover. These are the most critical points for construction stage inspections.
You can add this clause under the "Site Access" or "Inspections" section of your contract. If no such section exists, create a new clause titled "Independent Inspections" and insert it before the signatures page.
Negotiating With Your Builder
Present the inspection clause during your initial contract review, not at the signing meeting. This gives the builder time to consider it without pressure and demonstrates your knowledge of construction contracts.
Most reputable builders will accept the clause with minimal pushback. Those who strongly resist may be planning to cut corners or operate without adequate quality control. Their resistance itself is a red flag worth noting.
Review the Draft Contract
Read the entire contract before your meeting. Identify existing clauses about site access, inspections, and third-party visits.
Prepare Your Amendment
Type out the inspection clause on a separate page with your contract reference number. Have multiple copies ready.
Present During Initial Discussion
Explain that independent inspections protect both parties by identifying issues early. Emphasise that your inspector carries insurance.
Document the Agreement
Ensure the clause is added to the contract before signing. Both parties must initial the amendment.
If the builder insists on charging a supervision fee, negotiate a fixed amount per inspection rather than an hourly rate. A fair compromise is $100 to $200 per visit, significantly less than the $500 to $2,000 some builders attempt to charge.
Consider walking away if a builder absolutely refuses independent inspections. This refusal suggests they operate without transparency or adequate quality assurance processes.
What If Your Contract Is Already Signed
If you have already signed a contract without an inspection clause, you still have options. First, review your contract carefully to understand the exact restrictions in place.
Contact your builder in writing requesting a contract variation to add the inspection clause. Under the Home Building Act 1989 (NSW) and similar legislation in other states, contract variations must be documented in writing and signed by both parties.
- Review existing contract for inspection restrictions
- Request written contract variation from builder
- Offer reasonable compromises if needed
- Document all correspondence about inspections
- Consider legal advice if builder refuses
If your builder refuses to vary the contract, you may still be able to arrange inspections by working within the existing terms. For example, if the contract allows site visits by the owner, you could visit the site with your inspector present as your advisor.
Some builders may agree to remove supervision fees if you limit inspections to specific critical stages. Focus on obtaining access for pre-handover inspections at minimum, as this is the final opportunity to identify defects before practical completion.
Legal Considerations
Under Australian consumer law, contract terms that are unconscionable or significantly imbalanced may be challenged. However, legal action should be a last resort. Consult a construction lawyer if your builder's restrictions seem unreasonable.
In extreme cases where a builder completely refuses access and charges excessive fees, this may constitute a breach of good faith. Document all correspondence and consider lodging a complaint with your state building regulator (NSW Fair Trading, QBCC, VBA, or Consumer and Business Services SA).
Alternative Strategies
Some homeowners negotiate inspection rights as part of the overall contract package. For example, you might accept a slightly higher contract price in exchange for confirmed inspection access. This allows the builder to budget for any perceived administrative burden.
Another approach is to specify inspection requirements in your preliminary agreement or letter of intent before the formal contract is drafted. This establishes expectations early in the negotiation process.
Pros
- Independent inspections identify defects early when they are cheaper to fix
- Written reports provide evidence if disputes arise later
- Builder knows work will be scrutinised, encouraging higher quality
- Peace of mind throughout the construction process
Cons
- Additional cost of $400 to $800 per inspection
- May create tension with builder if not handled professionally
- Requires coordination and scheduling
- Some builders may increase contract price to offset perceived risk
If you are building in a challenging market where builders have significant bargaining power, prioritise inspection access at slab, frame, and pre-handover stages rather than insisting on unlimited access. Quality is better than quantity when it comes to construction inspections.
Frequently Asked Questions
QCan my builder legally prevent me from having independent inspections?
No. While builders can set reasonable conditions for site access, they cannot completely prevent you from engaging independent inspections in Australia.
Your contract may include restrictions or fees, but absolute prohibition of inspections would likely be considered unconscionable under Australian Consumer Law. However, the specifics depend on your contract terms and state legislation. If a builder attempts to block all inspection access, contact your state building regulator for guidance.
QHow much notice should I give my builder before an inspection?
48 hours written notice is standard and reasonable for construction inspections in Australia.
This gives the builder adequate time to ensure the site is safe and the relevant work stage is accessible. Some contracts may require longer notice periods of 5 to 7 days. Always provide notice in writing (email is acceptable) and include the inspector's name, insurance details, and expected arrival time.
QWhat is a reasonable supervision fee for the builder to charge?
If any fee is charged, $100 to $200 per inspection visit is reasonable. Fees above $500 are excessive.
Many builders charge no supervision fee at all, as inspections benefit both parties by identifying issues early. If your builder insists on a fee, negotiate a fixed amount per visit rather than hourly rates. Be wary of builders demanding $1,000 or more per inspection, as this is designed to discourage oversight rather than cover legitimate costs.
QAt which stages should I arrange inspections?
The most critical stages are slab pour, frame stage, waterproofing, and pre-handover inspection.
Slab inspections verify the foundation is level and reinforcement is correct. Frame inspections check structural elements before they are covered. Waterproofing inspections ensure wet areas are properly sealed. Pre-handover inspections identify defects before practical completion. Additional inspections at lock-up stage and after service installations can also be valuable.
QWhat happens if the inspection finds defects?
Your inspector provides a written report detailing any defects found. You then present this to your builder for rectification before proceeding to the next stage.
Under Australian building contracts, the builder is responsible for rectifying defective work. Early identification through inspections allows fixes while the area is still accessible, saving significant cost and delay. If a builder refuses to address identified defects, this may constitute a breach of contract. Consider booking defect investigation reports for serious issues.
QDoes my inspector need special insurance to access the building site?
Yes. Professional building inspectors must carry public liability insurance of at least $10 million to access construction sites in Australia.
This insurance protects both you and the builder if the inspector is injured on site or causes accidental damage. All reputable inspectors carry this insurance as standard. Your builder may request proof of insurance before allowing site access, which is a reasonable requirement to include in your inspection clause.
QCan I do my own inspections instead of hiring a professional?
You can visit the site as the owner, but you may miss critical defects without professional training and experience.
Licensed building inspectors have specific training in identifying structural issues, code compliance problems, and construction defects that are not obvious to untrained observers. They also provide written reports with photographic evidence, which is essential if disputes arise. If budget is a concern, prioritise professional inspections at the most critical stages rather than attempting DIY inspections.
QWhat if my builder says their contract is non-negotiable?
All contracts are negotiable before signing. If a builder refuses reasonable amendments, consider whether you want to proceed with that builder.
While some large volume builders have less flexibility with standard contracts, most will accept reasonable amendments that do not significantly increase their risk or costs. A builder who refuses to discuss any contract variations may lack flexibility during the build itself. Consider obtaining quotes from multiple builders and comparing their willingness to accommodate inspection clauses.
