Building Inspection Reports

🔎 A Professional Look at the House Itself

A building inspection report, often called a builder report or pre-purchase inspection, is a professional assessment of the physical condition of a property. An inspector examines the building and writes up what they find: the state of the structure, roof, weathertightness, dampness, and any defects or maintenance issues. For most buyers, it is one of the most valuable checks you can do, because it tells you about the actual house, not just the council paperwork.

Key Point: A building inspection report assesses the physical condition of the property, the things you can see and that an inspector can reasonably access. It is different from a LIM, which is council records. A building report can reveal defects, weathertightness concerns, dampness, and maintenance needs, helping you decide whether to buy, renegotiate, or walk away. But it has limits: an inspector cannot see inside walls or guarantee hidden problems, so it reduces risk rather than removing it.

What a Report Typically Covers

  • The structure and general condition of the building.
  • The roof, cladding, and signs of weathertightness issues.
  • Dampness, moisture, and ventilation concerns.
  • Visible defects and maintenance that will be needed.

📋 Building Report vs LIM

Buyers often confuse the building report with the LIM, but they tell you very different things, and serious buyers usually get both.

About the building itselfAbout the official record and history

Why You May Want Both

The building report tells you whether the house is sound today; the LIM tells you what the council knows, like whether work was consented and whether the land has known hazards. A problem can show up in one but not the other. For example, an unconsented addition might appear on the LIM, while a leaking roof shows in the building report. See our guide on reading a LIM report.

They are complementary, not interchangeable: A clean building report does not mean the council records are fine, and a clean LIM does not mean the house is sound. Getting both gives the fullest picture before you commit.

⚠️ What a Report Can and Cannot Do

What It Can Find

A good inspection can identify visible and reasonably accessible problems: a sagging roofline, signs of moisture, cracked cladding, poor drainage, deferred maintenance, and safety concerns. It often gives you a sense of how urgent and costly issues might be, which is powerful information for your decision and any negotiation.

What It Cannot Do

An inspector generally cannot see inside walls, under floors beyond access, or behind linings, and does not pull the building apart. So hidden problems can remain undetected. A report is a professional opinion based on what could be observed on the day, not a guarantee that there are no issues. For specific concerns, like weathertightness in at-risk homes, a more specialised assessment may be needed.

An inspector examines accessible parts of the property
They report visible defects, moisture, and maintenance needs
You learn the likely condition and rough cost of issues
Hidden problems may remain, so it reduces but does not remove risk
Use a suitable, independent inspector: Choose a competent, independent inspector and check what the report covers and its limitations. A report written to a recognised standard, by someone not connected to the sale, gives you the most reliable picture.

💡 Using the Report in Your Decision

Make It a Condition

Unless you are buying at auction, you can usually make your offer conditional on a satisfactory building report. That lets you get the inspection after your offer is accepted and withdraw or renegotiate if it reveals serious problems. At auction, you must get the report before bidding, since there is no condition. See our guides on conditional offers and auctions versus deadline sales.

What to Do With the Findings

  • Minor maintenance: normal for most homes; factor it into your plans.
  • Significant defects: get quotes, and consider renegotiating the price or asking for repairs.
  • Serious or costly problems: a building report condition lets you walk away.
  • Specialist concerns: follow up with a specialist assessment if the report flags one.
A report can save far more than it costs: The fee for a building inspection is small against the price of a home and tiny against the cost of an undiscovered major defect. Even when a report is clean, the peace of mind is worth it. Skipping it to save a little is a false economy.

Pair this with the sale and purchase agreement guide and the First Home Buyer Calculator. Final word: a building inspection report is a professional assessment of the physical condition of a property, distinct from the council LIM. It reveals visible defects and maintenance needs but cannot guarantee hidden problems are absent. Make it a condition where you can, get both a building report and a LIM, and use the findings to decide, renegotiate, or walk away. This is general information, not legal or building advice.
