Your inspection is done, and a long PDF full of photographs, technical terms and caveats has just arrived, probably while you are also juggling a lender, a lawyer and a condition deadline. A well-prepared building report is designed to be read in layers, and working through it in a set order makes it far easier to absorb.
Start with the summary
Most reports open with an overview. This is where the inspector lists the most significant findings and gives an overall impression of the property’s condition relative to its age and type. Many use a priority system, such as traffic-light colours or ratings like major, moderate and minor, to separate urgent defects from routine maintenance.
Read the summary twice. Note anything described as significant, structural, a safety concern or needing further investigation. Those are the items most likely to affect your decision or your negotiation. If a partner, family member or lender is involved, this is also the part to share first.
Then read the limitations
This is the section many buyers skip, and it is one of the most important. It tells you what the inspector could not see or test: areas with no access, furnished rooms where walls were hidden, roofs that were not walked because they were unsafe, or services such as wiring and gas that sit outside the inspector’s scope. Reports prepared to NZS 4306:2005 are expected to set out these limits clearly.
A limitation is not a defect, but it is an unknown. If the subfloor wasn’t entered or the roof space was only viewed from the hatch, ask whether a return visit is possible once access improves.
Work through the detail area by area
The body of the report usually moves through the site, exterior, roof, roof space, subfloor, interior and services. Match each photo to its comment, and look up any unfamiliar terms. Flashings, soffits, bearers, scribers and cavity battens all have plain meanings once explained.
Notice the difference in wording between defects and maintenance. A defect is something that is not performing as it should, such as a failed flashing, a cracked pile or a leaking waste pipe. Maintenance items are things that will need attention as part of normal ownership: repainting, clearing spouting, replacing worn sealant. A long list of maintenance items on an older house is normal and often manageable. A short list that includes a significant structural or weathertightness defect may matter far more.
Give particular weight to recommendations that mention a specialist: an electrician, plumber, drainlayer, structural engineer or weathertightness expert. These are signals that the inspector has seen enough to be concerned but not enough to judge the full extent.
Once the findings make sense, decide what to do with them. Rough quotes for the larger items turn comments into numbers. Those numbers can support a request for the vendor to carry out repairs, a price adjustment, or a decision to walk away within your condition period.
Finally, call the inspector. Most are happy to talk through their findings, and a short conversation can clarify whether a comment is a minor note or a reason to rethink the purchase. Jot your questions down beforehand so nothing gets forgotten under time pressure.
