What is Compare My Build?

An interactive comparison platform for home buyers to evaluate builders, plans, and inclusions in their region side-by-side.

Can I use my own building inspector?

Yes. In Australia, buyers are generally entitled to arrange an independent building inspector to attend key stages of construction. Your building contract should outline how site access is arranged — check the site access and inspection clauses.

Can a builder refuse access to my inspector?

A builder can set reasonable conditions around site access for safety and insurance reasons (like notice periods, inductions, or supervisor coordination), but outright refusing all independent inspections is unusual and worth questioning. Check your contract and ask for the policy in writing.

Can a builder charge an inspection fee?

Some builders do charge fees described as admin, access, supervision or induction fees. Whether this is reasonable depends on your contract and what the fee actually covers. If it wasn't disclosed before you signed, you should question it and seek advice.

What if the fee was not in my contract?

If a fee appears that wasn't disclosed in your signed contract, ask the builder to explain in writing what it covers and where it's authorised. You may want to raise this with your state building authority or seek legal advice before agreeing to pay.

Should I pay the fee?

This depends on your specific contract terms and circumstances — we can't give legal advice here. If a fee seems reasonable and disclosed, many buyers choose to pay it to keep the relationship smooth. If it seems excessive or was never mentioned, get advice before paying.

What stages should an inspector attend?

Common stages include base/slab, frame, waterproofing, pre-plaster (lock-up), practical completion (PCI) and handover. Not every buyer inspects every stage — frame and PCI are the two most commonly recommended.

Does the inspector need insurance?

Reputable independent building inspectors typically carry professional indemnity and public liability insurance. Builders may reasonably ask for proof of this before granting site access, which is a normal safety and risk requirement.

Who can I contact if I think the fee is unfair?

Each state has a building regulator or consumer affairs body that handles building disputes — such as the QBCC, NSW Fair Trading/Building Commission NSW pathways, the BPC in Victoria, CBS, Consumer Protection WA, Access Canberra, CBOS or NT Consumer Affairs. They can advise on your options.

Can a Builder Charge You to Use Your Own Private Inspector?

Some builders apply conditions or fees before letting an independent inspector attend site. Here's what that can mean, and what to check before you agree to pay.

9 min read·Compare My Build — Independent Resource· Updated September 2026

Many home buyers want an independent building inspector to check their build at key stages — slab, frame, waterproofing, pre-plaster, practical completion (PCI) and handover. It's a common and reasonable way to get a second opinion on the quality of the work.

But some buyers are told they'll need to pay an extra fee — described as an admin fee, supervision fee, induction fee or access fee — before their inspector can attend site. This guide explains what that can mean, what's generally reasonable, and what buyers should check before agreeing to pay anything.

Featured Snippet Answer

In Australia, a builder may set site access rules for safety and insurance reasons, but buyers should carefully check whether extra fees for using an independent inspector are clearly disclosed in the contract. If a fee seems excessive, unexpected or unfair, buyers should ask for it in writing and seek advice before agreeing.

Key Takeaways

Buyers can generally arrange their own independent inspector to attend key build stages.
Builders can set reasonable site access conditions (safety, notice, insurance) — but any extra fee should be clearly disclosed in your contract.
Common fee names include admin, site access, supervisor attendance, safety induction and reinspection fees.
If a fee wasn't disclosed before you signed, ask for it in writing and check your contract before paying.
Each state has a building authority (e.g. QBCC, NSW Fair Trading, BPC) that can help if a fee seems unfair.

Note

This guide is general information only and is not legal advice. Every building contract is different — always check your own contract carefully and speak with a qualified professional if you're unsure of your rights.

Why Buyers Use Private Inspectors

An independent building inspector works for you, not the builder. Common reasons buyers engage one include:

An independent second opinion on the quality of construction work
Identifying defects that may not be obvious to an untrained eye
Peace of mind at major milestones during the build
Support at the Practical Completion Inspection (PCI) and handover
Help understanding technical issues in plain English

Common Fees Buyers May Be Told About

Fees are sometimes described using different names. Here's what each commonly means, and a question worth asking about it.

Fee Type	What It May Mean	What to Ask
Admin fee	A general charge for the paperwork or coordination involved in allowing external access.	What specific admin tasks does this fee cover, and is it a one-off or per-visit charge?
Site access fee	A charge simply for allowing an outside party onto the site.	Is this fee standard across all clients, or specific to independent inspectors?
Supervisor attendance fee	Covers the site supervisor's time if they need to be present during the inspection.	Is supervisor attendance actually required by law or policy, or is it optional?
Safety induction fee	Covers the cost of a site safety induction the inspector may need to complete.	Is this a standard WHS requirement, and can the inspector complete it once for the whole build?
Reinspection fee	Charged if a follow-up inspection is needed after defects are found and rectified.	Is this fee triggered only by defects the builder caused, and how much is it?
After-hours inspection fee	An extra charge if the inspection needs to occur outside normal trading hours.	Can the inspection be scheduled within standard hours to avoid this fee altogether?

Is It Normal?

Some site access requirements are reasonable — building sites are workplaces, and safety rules exist for good reason. Coordinating an inspection time with a site supervisor is also normal practice on an active construction site.

What's less normal is an unexpected or high fee that wasn't disclosed before you signed. If a fee appears only once you ask for an inspection, or seems disproportionate to the actual work involved, it's reasonable to question it and check whether it was properly disclosed in your contract.

Watch Out

If a fee wasn't mentioned anywhere in your signed contract, don't assume you have to pay it without checking further. Ask the builder to explain it in writing and confirm where in the contract it's authorised.

What to Check in Your Building Contract

Site access clause — who is allowed on site and under what conditions
Inspection clause — your rights to arrange independent inspections at each stage
Variation clause — whether fees like this can be added after signing
Independent consultant clause — specific terms about third-party professionals attending
Supervisor attendance requirements — whether a supervisor must be present and why
Any fee schedule — a list of charges attached to or referenced in the contract
Whether fees are fixed, hourly, or discretionary — this affects how predictable your costs are

QAre the fees listed in my contract?
