When you’re standing in a property during an inspection, listening to an inspector point out issues, it all seems pretty straightforward. You nod along, maybe take a few notes on your phone. But try remembering specific details two weeks later when you’re sitting in your lawyer’s office. Was it the southwest corner where the moisture reading was high? Or the southeast? What exactly did the inspector say about the subfloor ventilation?
This is where written building reports earn their keep. Unlike a verbal inspection, where you’re relying on memory and hastily scribbled notes, a written report puts every finding on paper with photos and specific details. You can review it as many times as needed, share it with your lawyer or bank, and refer back to it months or even years later.
Banks particularly prefer written documentation. When you’re applying for a mortgage, telling them “the inspector said it looked okay” doesn’t carry much weight. They want to see professional documentation that formally assesses their security. The same goes for insurance companies if you need to make a claim down the track—written evidence of the property’s condition at purchase can be the difference between approval and rejection.
I’ve been inspecting properties for decades now, and I can tell you that verbal walkthroughs have their place for quick decisions. But when it comes to a purchase that’ll affect your finances for decades, you need everything documented. A written report gives you something concrete to show your bank, lawyer, or the seller when negotiating repairs or price adjustments.
New Zealand poses unique challenges for buildings. We’ve got expansive clay soils in many regions that shift with changes in moisture, varied rainfall patterns that test every weatherproofing system, and plenty of older homes that weren’t built to modern standards. Add in the mix of character villas, 1970s brick homes, and newer subdivisions, and you’ve got a real variety of potential issues. A written report captures all of this in detail.
The pre-purchase stage is when you need the most documentation. A phone call from an inspector isn’t going to cut it when your lawyer asks exactly what structural issues were found, or when you’re trying to remember specific details two weeks later.
Pre-purchase reports document everything we find—from minor maintenance items right through to severe structural defects. You get photos of every problem area, descriptions of what’s wrong, and often an indication of roughly what repairs might cost.
Last month, we inspected a place that looked fantastic on the surface. Sellers had it listed as “recently renovated”, and the cosmetic work was genuinely impressive. But the written report showed rot in the subfloor framing that they’d covered over rather than fixed. The buyers now had solid evidence to take back to their lawyer and decide how they wanted to proceed.
Banks also prefer written reports. Most lenders want to see proper documentation of the property’s condition before approving mortgages. The written format gives them confidence that a qualified professional has properly assessed their security.
Not every inspection happens because you’re buying. Sometimes you already own the place, and you want to know what shape it’s in. Maybe you’re planning renovations and want to know what problems to fix first, or you’re thinking about selling and want to discover issues yourself rather than have buyers find them.
Long-term homeowners often request inspection reports when they’re planning maintenance work. One property we assessed had been in the same family for fifteen years. The owners wanted a clear picture of what needed attention—weatherboards showing wear in several spots, roofing materials approaching replacement age, that sort of thing. The written format gave them a maintenance roadmap they could work through systematically over the following seasons.
Home inspection reports also help with insurance claims. Having a recent written report showing the property’s condition before storm or flood damage can make claims processing much smoother. It establishes what was already wrong versus what the event actually damaged.
Commercial properties come with their own set of inspection challenges. Whether you’re buying an office building, retail space, or industrial unit, the stakes are often higher than in residential purchases. Commercial building reports need to cover structural condition, factors affecting business operations, and regulatory requirements.
We recently inspected a commercial building being converted from a warehouse to office space. The buyer needed to understand what they were taking on. The written report outlined the structural realities, highlighted where building modifications would require engineering sign-off, and flagged some fire safety and accessibility considerations. Having everything documented meant they could get accurate quotes from contractors and plan the project timeline realistically.
Commercial reports often get shared among multiple stakeholders. Investors, banks, lawyers, engineers, and architects might all need to review the findings. The written format makes this easy. Having detailed documentation of the building’s condition at each sale point helps track deterioration over time and identify recurring problems.
Borer and timber pests are serious business in New Zealand. These insects can quietly destroy structural timber for years before you spot visible signs. That’s why pest inspection findings need to be written down with photos and details.
A character home showed active borer in the roof framing during inspection. The written report included close-up photos showing fresh bore dust and flight holes. When the owners contacted pest treatment companies, everyone was working from the same clear information about the location and extent of the problem. Made the whole process more straightforward.
Pest reports document the extent of any infestation, identify the type of pest, and note whether it appears active or old. This matters because treatment costs and methods differ. Some properties have evidence of old borer damage that was treated decades ago. Other places have active infestations needing immediate treatment. A written report clearly distinguishes between these scenarios.
Banks and insurance companies both care about pest problems. Severe pest damage can affect property value and lending approval. Written documentation helps avoid surprises later when the bank does its valuation.
Water is the enemy of New Zealand buildings. Moisture intrusion is one of the most common serious problems we find during inspections. Moisture testing needs careful documentation because moisture levels alone don’t tell the whole story—you need to record where the moisture is, how extensive it is, and what building elements are affected.
A written moisture testing report includes readings from multiple locations. We test external walls, internal walls near wet areas, around windows and doors, and in subfloor spaces. Each reading gets recorded with a photo showing exactly where it was taken.
Last winter, we looked at a property where moisture readings told an interesting story. Most walls were sitting at normal levels—under 20%—but one section of the master bedroom was reading 35-40%. Having those specific numbers and locations written down, along with photos, made it easy to trace the problem back to a window seal that needed replacing—a simple fix once you know exactly where to look.
New Zealand’s weather patterns mean moisture testing is critical across the country. Different regions experience varying rainfall and humidity levels. Older homes, especially, are prone to moisture problems because they were built before modern weathertightness standards. A written moisture testing report identifies these problems before they become costly rot and structural decay.
Sometimes, property problems are complex enough that you need more than a standard inspection. Building consultant reports go beyond identifying problems to analysing them and recommending solutions.
A building consultant’s report might investigate specific defects such as foundation movement, analyse weathertightness failures, or assess whether previous repairs were carried out correctly. These reports often include technical details about building performance, structural calculations, and references to building standards.
One property demonstrated why consultant-level reports matter for complex issues. The owners had paid for moisture repairs that didn’t solve the problem. The building consultant report didn’t just document what was wrong—it explained why previous fixes hadn’t worked and what approach would actually solve the problem long-term. That level of technical analysis needs to be adequately documented so everyone involved understands the whole picture.
Consultant reports often form part of legal proceedings or insurance disputes. In these situations, having everything documented adequately with professional opinions and supporting evidence is critical. Verbal discussions won’t hold up in court or with insurance assessors—you need written professional reports.
For complex renovation projects, building consultant reports help identify what work is needed and in what order. You might discover that fixing a leaking roof is pointless until you address ground drainage that’s causing rising damp. The written format lets you plan renovation work logically and budget accurately.
If you’re buying a property with known defects, a building consultant report gives you detailed information about repair costs and methods. This information is valuable when you’re negotiating price reductions or deciding whether a cheaper property with problems is actually a better deal than a more expensive property in good condition.
