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.
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.
| Building inspection report | LIM report |
|---|---|
| Assesses the physical condition of the house | Provides council-held information about the property |
| Done by a building inspector | Issued by the local council |
| Finds defects, dampness, maintenance issues | Shows consents, zoning, hazards, rates, and records |
| About the building itself | About 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.
⚠️ 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.
💡 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.
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.
