Builder's Report NZ

What Is a Builder's Report?

In New Zealand real estate, a "builder's report" is the common term for a building inspection report — a detailed written assessment of a property's physical condition prepared by a qualified building inspector. The term is not a formal legal definition, but it is widely understood by buyers, sellers, real estate agents, and solicitors across the country.

A builder's report is most often commissioned during the conditional period of a property purchase, though sellers sometimes arrange one before listing to identify issues upfront. Property owners may also request a report before planning renovations, for insurance purposes, or simply to understand the current state of their home.

What a Builder's Report Should Contain

A thorough builder's report typically includes:

• Property details — address, legal description, property type, age, and construction materials
• Scope of inspection — a clear statement of what was inspected and, just as importantly, what was not (e.g. areas that were inaccessible or excluded)
• Findings by area — roof, exterior cladding, subfloor, interior rooms, wet areas, electrical and plumbing (visual only), and site drainage
• Photographic evidence — photos of defects, areas of concern, and general condition
• Prioritised recommendations — issues categorised by severity, from urgent safety concerns to minor maintenance items
• Limitations and disclaimers — honest acknowledgement of what a visual inspection cannot detect

The New Zealand Standard NZS 4306:2005 provides a framework for residential property inspections, covering the expected scope, reporting format, and limitations. While not all inspectors follow this standard, it can be a useful benchmark when comparing reports.

How a Builder's Report Differs from an Engineer's Report

A builder's report is a general assessment of the whole property. An engineer's report (or structural engineer's assessment) is a specialist evaluation focused on specific structural concerns — for example, foundation cracking, retaining wall stability, or earthquake damage. If a builder's report identifies potential structural issues, the inspector may recommend a follow-up engineer's assessment for those specific items.

What Makes a Good Report

Not all builder's reports are equal. A quality report uses clear, plain language rather than vague terms. It includes enough photographs to support every significant finding. Findings are prioritised so the reader can distinguish between a safety hazard and a cosmetic issue. The report should also be honest about limitations — no visual inspection can see inside walls or under concrete slabs.

How Reports Are Used in Property Transactions

During a conditional purchase, the buyer's solicitor may use findings from a builder's report to negotiate price adjustments, request repairs, or in some cases advise the buyer to withdraw. Sellers who commission their own pre-sale report may choose to address issues before listing, potentially reducing the risk of renegotiation. Either way, the report serves as a factual record of the property's condition at a specific point in time.
