A LIM tells you what the council knows about a property. It doesn't tell you whether the roof is about to leak or the foundation's moving. That's what a building inspection is for, and for most first-home buyers, it's the other essential check alongside the LIM.
The short answer
A building inspection is a physical assessment of a property's condition, carried out by a qualified building inspector, usually before you go unconditional. It typically costs $400 to $900 for a standard residential inspection, and it's the main way to find out about structural, weathertightness, or maintenance issues before they become your problem.
What a building inspection actually covers
A standard pre-purchase inspection is a visual, non-invasive check of the property, looking at things like:
- Structure and foundations. Cracking, movement, subsidence.
- Roof and cladding. Condition, obvious leaks or damage, likely remaining life.
- Moisture. Damp readings in walls, a particularly important check in older or monolithic-clad New Zealand homes.
- Plumbing, wiring, and insulation, to the extent visible without removing linings or fixtures.
- General maintenance issues, the kind of thing that's not urgent but tells you what you're signing up for over the next few years.
It's a visual inspection, not an invasive one. If the inspector flags something concerning, like a moisture reading that suggests a bigger problem, the next step is usually a more targeted specialist report.
Building inspection vs LIM: they're not the same thing
These two get mixed up constantly, and they answer genuinely different questions.
| LIM report | Building inspection | |
|---|---|---|
| Who does it | The local council | An independent qualified inspector |
| What it checks | Council records: consents, hazards, rates | The physical condition of the building |
| Finds | Unconsented work on paper, zoning, flood risk | Leaks, moisture, structural issues, maintenance needs |
| Typical cost | $200 to $450 | $400 to $900 |
Neither one replaces the other. A property can have a clean LIM and still have real physical problems the council never recorded, and a building inspection won't tell you about a hazard notice sitting in council files. For most first-home buyers, both make sense. See our full LIM report guide for the council side of it.
Do you actually need one?
It's not a legal requirement, but it's one of the most valuable pieces of due diligence available to you, especially for an older home or anything you haven't had properly looked at by a professional. The usual approach is to make your offer conditional on a satisfactory builder's report, so a bad result gives you a genuine way to walk away or renegotiate. More on how conditions work in our Sale & Purchase Agreement guide.
Some situations where it's especially worth insisting on one:
- Older homes, where wiring, plumbing, and roofing are more likely to be near the end of their life.
- Homes with monolithic cladding (plaster-look exteriors from the late 1990s and 2000s), a well-known weathertightness risk category in New Zealand.
- Anything that looks like it's had DIY work done, which pairs well with checking the LIM for matching consents.
Choosing an inspector
Look for someone qualified through the Licensed Building Practitioner scheme or a recognised building surveying qualification, and ideally someone who carries professional indemnity insurance. A cheap inspection from someone without the right qualifications isn't much of a safety net if it misses something significant.

Frequently asked questions
How much does a building inspection cost in New Zealand?
A standard pre-purchase building inspection typically costs between $400 and $900, depending on the size of the property and the level of detail in the report. It's paid separately from your conveyancing fee, as a disbursement or direct booking with the inspector.
Is a building inspection the same as a LIM report?
No. A LIM comes from the council and covers its records: consents, hazards, and rates. A building inspection is a physical, on-site check of the property's actual condition, carried out by a qualified inspector. Most first-home buyers benefit from having both.
Do I need a building inspection to buy a house in NZ?
It's not legally required, but it's strongly recommended, particularly for older homes or anything with cladding types known for weathertightness issues. Making your offer conditional on a satisfactory building inspection gives you a way to walk away if something significant turns up.
What does a building inspector check?
A standard inspection covers the structure, roof, cladding, visible plumbing and wiring, insulation, and moisture levels, along with general maintenance issues. It's a visual, non-invasive assessment rather than one that involves removing linings or fixtures.
Who should do my building inspection?
Choose someone qualified through the Licensed Building Practitioner scheme or an equivalent recognised qualification, ideally with professional indemnity insurance. Your conveyancer or real estate agent can often recommend inspectors they trust.
