What does being an owner-builder mean for inspections?
An owner-builder is a person who takes on the role of the builder for work on their own property, rather than engaging a registered builder to run the project. That role comes with responsibility. You organise the trades, you keep the paperwork, and you remain responsible for the building work itself, during the build and after it is finished.
Inspections sit at the centre of that responsibility, and there are two different kinds. The first kind is mandatory: the inspections your building permit requires, carried out by, or on behalf of, the relevant building surveyor. The second kind is independent: an inspection you choose to commission for your own information, at a stage you pick. They look at the same house but they do different jobs, and it helps to keep them clearly apart from the start.
This guide is the starting point for owner-builders. It covers the mandatory inspections, when an independent look is worth arranging, what you may need before you sell a home you built, what a report includes and leaves out, and the records worth keeping from day one. Our owner-builder inspections service page sets out what we offer in each of those situations.
Which inspections are mandatory and who carries them out?
Most owner-builder projects need a building permit, and some also need a planning permit from the council. A building permit is issued by a building surveyor, who may work for the council or privately. Our guide to which permits apply to building work in Victoria explains the difference between the two permits and who confirms what applies.
Once a building permit is in place, it sets out the stages at which the work must be inspected before it can continue. The relevant building surveyor carries out those inspections, or arranges for them to be carried out, and tells you what happens at each stage. The surveyor's role is defined by the permit.
Your part is to call for the inspection at the right time, to make the work available for it, and to act on what the surveyor says. If a stage is covered before it has been inspected, the surveyor may ask for it to be opened up again, so it pays to build the inspection points into your schedule from the start.
Those mandatory inspections are not something we provide, and nothing we do replaces them. If you are unsure which stages your permit requires, or who your building surveyor is, the permit documents will say, and your council or the Victorian building regulator can point you to the current requirements.
When is an independent inspection worth arranging during the build?
An independent inspection is a second pair of eyes on the work, at a stage you choose. It is visual and non-invasive, and it describes what could be seen on the day. Many owner-builders arrange one because they are coordinating trades they do not know well, because a stage is about to be covered up, or simply because they want a plain-language record of how the work looked before moving on.
Common moments to consider are before a slab is poured or a floor frame is closed in, once the frame is up and before linings go on, when the house is at lock-up, and when the work is practically complete. The stages you choose are agreed in the scope, and our new-building inspections page explains stage inspections in more detail. The same principle applies whether the project is a whole home, an extension or a major renovation.
At each stage we look at what is visible and accessible: the set-out and finish of the work done so far, the way different trades' work meets, any items that look unfinished or out of place, and anything that would be worth a closer look before it is covered. We do not direct the trades and we do not take over the project. The decisions stay with you.
What you receive is a written report, organised area by area, with photos supporting the key observations and a clear list of what could not be inspected and why. Where something looks like it needs a closer look, the report says so and suggests the kind of practitioner to ask, for example a structural engineer where the signs point to a structural concern.
The report is yours. It is not part of the permit process, and it does not stand in for any mandatory inspection. If you are building to a point where a registered builder or trade hands part of the work over to you, a handover inspection can also give you a dated record of that part before you take it on.
What should you know before selling a home you built?
Selling a home as the owner-builder who built it can come with obligations that do not apply to other vendors. Those obligations may include an inspection report prepared before the sale, and may extend to other requirements, such as what you must tell the buyer. The details depend on your situation, and they can change.
The first step is always the same: check the current requirements with the Victorian building regulator, and ask your conveyancer or lawyer how they apply to your sale. Do this before you list, not after a buyer has asked, because the requirements may set out who can prepare the report and what it must include.
Once you know what the report needs to cover, and who is able to prepare it, tell us about the property, when the work was done and your timing. We will confirm whether we can help before anything is booked. If the requirements call for a practitioner we are not, we will say so and suggest the kind of practitioner to look for.
Buyers of owner-built homes often ask their own questions too. They may want to see the permits, the records of the mandatory inspections and any certificates from the build, and many will arrange their own pre-purchase inspection. Having your records in order before you list makes those conversations simpler and shorter.
What goes into the report, and what does it leave out?
A report from an independent inspection describes the visible condition of the accessible areas of the home at the time of the inspection. Inside, that means the rooms, wet areas, windows and doors, and the roof space and subfloor where there is safe and reasonable access. Outside, it means the walls, roof areas that can be seen safely, paths, fences and outbuildings as agreed in the scope.
Visible defects, unfinished work and items worth a closer look are recorded with photos, and each is placed so you can find it again. The report is written in plain language, and you can ask us about anything in it.
It is just as important to be clear about what a report is not. It is not a certificate of compliance, an approval, a warranty or an insurance document. It is not a structural engineering assessment, and it is not legal advice about selling. It cannot see inside walls, under floor coverings or in areas that are unsafe to reach, and those gaps are listed as limitations rather than quietly left out.
As the owner-builder, you remain responsible for the building work whatever a report says. A report helps you understand what was visible on the day so you can decide what to do next. Compliance with the permit is a matter for the permit process and the relevant building surveyor.
Which records should you keep from day one?
The paperwork is where many owner-builder projects run into trouble, usually years later when a buyer or a conveyancer asks for something that was never filed. Start a folder on the first day and keep adding to it. Useful things to keep include:
- The building permit, the planning permit if there is one, and the approved plans.
- Records of each mandatory inspection and any directions from the building surveyor.
- Certificates and invoices from licensed trades, especially plumbing and electrical work.
- Product information and warranties for materials and fittings.
- Any independent inspection reports you commissioned during the build.
- Dated photos of each stage before it was covered up.
- Correspondence with the council, the building surveyor and any consultants.
If the build is already finished and the folder is thin, our documentation assistance service helps you work out what you have, what is missing and where it may be found. Our guide to the property documents every owner should keep sets out the wider list that applies to any home.
Keeping these records is not only about a future sale. If a question comes up about a stage of the work, a dated photo or a report from the time can answer it in minutes. Without one, the only way to look is to open the work up, which costs time and money and may not be possible at all once the home is finished and lived in.
Tell us about your property, the stage you are at and what you want the inspection for, and we will help with the next step. Call or message us on 0406 194 163, or send an enquiry and we will come back to you.
