Can I ask a builder friend to inspect my new home instead of hiring a building inspector?

Will you have a written record?

Say your friend notices poor drainage outside a door, or a balcony detail that does not look right. They mention it, and you pass it on to the builder.

Six months later it still has not been fixed, and nobody agrees on whether it was there at handover, what was said or whether a repair was promised. Without anything in writing, that conversation is hard to reconstruct.

An inspection report usually records:

• what could be seen on the inspection day;
• where each item is;
• photos, and measurements where they were taken;
• the requirement the item was checked against, where that can reasonably be established; and
• whether it needs fixing or a specialist should look at it.

An experienced builder can write a report too. But a favour from a friend is usually a walk-through, not a systematic inspection with a written result.

A dated report helps if a defect is disputed

People can disagree about whether a defect exists, when it appeared, what caused it, how big it is and who should fix it.

Consumer Affairs Victoria suggests inspecting the house thoroughly before you take possession and listing any issues on the handover sheet, noting that this may help avoid disputes about who is responsible for fixing them.1 If a dispute does arise, the Building and Plumbing Commission offers free dispute resolution between homeowners and builders, with binding orders or VCAT as further steps.2

A report written at the time records the condition of the work at that stage, before it is covered up or before you move in. Photos, measurements and clear descriptions also make your emails to the builder more precise.

A report does not win a dispute for you. A standard pre-handover report is not the same as an expert witness report prepared for a tribunal, and how much weight any document carries depends on the case. What people remember can still matter, but a written record makes it easier to show what was seen, when, and what was raised.

Building a house and inspecting one overlap, but they are different jobs

A builder knows materials, trades, sequencing and workmanship, and that knowledge is valuable.

An inspector’s job is to look at finished or part-finished work critically, using a consistent method, and to check it against the relevant requirements where needed. Those can include the National Construction Code, Australian Standards, the approved plans and the contract specifications.

Nobody remembers every requirement. Part of the job is knowing when to look something up, telling a defect apart from a matter of taste, and knowing when to send a question to a specialist.

A builder who mainly does framing may be excellent at timber construction but see less waterproofing or drainage detail day to day. Inspectors vary too. Years in the industry do not, on their own, show that every detail has been checked against the requirements that apply.

An inspection follows a set method

A friend will quickly see a crooked door, a damaged finish or an obvious leak. An inspector should work through an agreed scope for that stage and check each accessible part in turn, rather than noting whatever stands out.

Things an inspection may pick up include:

• poor falls and surface drainage;
• signs of moisture getting in, or questionable waterproofing details;
• roof flashing, gutter or downpipe problems;
• slab set-out, reinforcement and preparation before the concrete pour;
• frame bracing, tie-downs and connections before the walls are lined;
• stair, balustrade and handrail defects;
• windows and doors that are badly installed;
• unfinished or poor-quality finishes; and
• work that does not seem to match the plans or specifications.

Some items need measurements, testing, reference documents or a specialist. Some cannot be confirmed by a visual, non-invasive inspection at all.

Who is responsible for the findings

When you engage an inspector, the engagement should make clear who they are, what they will inspect, what they will report and what they are responsible for. Before booking anyone, ask about:

• their registration or qualifications, where relevant;
• how many new-home inspections they have done;
• their insurance;
• a sample report; and
• what the inspection does not cover.

A friend may be honest and helpful, but may not want to, or be able to, write a technical reply if the builder disagrees with them. Equally, do not assume a paid inspector will act as an expert witness later. That is normally a separate engagement.

An inspection does not guarantee every finding is right. What it gives you is a defined engagement and a written record of what was found.

A written list makes repairs easier to track

Even with a cooperative builder, defects raised in phone calls and on-site chats are hard to keep track of.

A report gives each item a location, a description and a photo. You can send it to the builder, ask for a written reply and tick items off as they are fixed. If something is serious, disputed or hard to judge after the repair, a follow-up inspection or a specialist may be worth it.

It can also keep the relationship friendly: both sides are working from the same list instead of different memories.

Each stage has its own window

A lot of the work in a new home is only visible for a short time. Slab reinforcement disappears under concrete, and frame connections disappear behind plasterboard. Once that happens, problems are much harder to check, and a friend who drops by now and then may not be there at the right moment.

An inspection booked at each key stage, such as before the slab pour, at frame, at lock-up, at fixing and before handover, records the work while it can still be seen. For what happens at each stage, see our new-home inspections page.

Handover is the last of these windows. Before furniture and belongings go in, more of the house can be seen. Once you are living there, everyday use, changes and later damage can make it harder to show what was there from the start. That does not mean the builder stops being responsible for defects after handover. The statutory warranties on domestic building work and your contract rights can continue.3

What if your builder has been good about fixing things?

That is a good sign. But fixing the defects someone has already pointed out is different from finding the ones nobody has noticed yet.

A cooperative builder, a capable friend and an independent inspector can all help with a smooth handover. You do not have to choose between them. If you are still at an earlier stage, see what builders may tell you about independent stage inspections.

So, the friend or the inspector?

Consider both. Bring your friend for a practical second opinion, and book an independent inspector at the stages that matter to you if you want a systematic check and a written report.

Read the inspection scope before you book. Most stage and pre-handover inspections are visual and non-invasive and cannot find every hidden or future defect.

The point is not to start an argument with the builder. It is to find problems early, put them in writing and make them easier to fix while the job is still fresh.
