Buying a home is one of the biggest decisions you’ll ever make, and for many first home buyers it’s also one of the more nerve-wracking parts of the process. Along with sorting finance and finding the right area, there’s another risk that can be worth understanding early on: leaky homes.
New Zealand has a history of weathertightness problems affecting some properties, particularly certain homes built in past decades. That doesn’t mean every older property has issues, but it can be worth knowing what to look for before you commit to a purchase.
This guide looks at what a leaky home generally is, some signs that may be worth a closer look, and how legal support in New Zealand can help you approach a purchase with confidence.
What a Leaky Home Generally Means
A leaky home is typically a property where water may have been getting into the building structure, often through the cladding, joinery, or roofline, rather than staying outside where it belongs. Over time, this can potentially lead to rot, mould, or damage to timber framing.
This issue has affected a range of New Zealand properties over the years, sometimes linked to certain building design trends, cladding systems, or construction methods that didn’t always allow water to drain away as intended.
Buying a home with weathertightness concerns does not necessarily mean the property should be ruled out, as many affected homes can potentially be repaired or remediated. That said, remediation work can sometimes be costly, so it may be something worth knowing about before you sign anything, rather than after.
Possible Signs a Property May Have Weathertightness Concerns
While a full building inspection is generally the most reliable way to assess a property, there are some visible clues that first home buyers and sellers alike may want to be aware of:
- Musty or damp smells inside the home, especially in wardrobes or corners
- Visible staining, bubbling paint, or soft spots on interior walls
- Cracked or deteriorating exterior plaster cladding
- Flat or low-pitched roofs with limited eaves
- Windows or doors set flush with the exterior cladding, without visible flashings
- Gardens or decking built up against the cladding, which may trap moisture
Spotting one of these signs doesn’t necessarily mean a property has weathertightness problems. It may simply be worth asking more questions and getting a professional opinion before going any further.
Building Reports and LIM Reports: Two Useful Starting Points
Two documents can be genuinely helpful when you’re weighing up a potential purchase.
A building report, generally carried out by a qualified NZ building inspector, looks at the condition of the property, including cladding, roofing, plumbing, and structural elements. A thorough inspector may also carry out moisture testing in areas that can commonly show problems.
A Land Information Memorandum (LIM report), obtained from the local council, may show consent history, any recorded weathertightness claims, and other information held by council.
These reports may help give you a clearer picture of what you could be taking on, supporting a more informed decision.
How a Due Diligence Clause May Help Protect Your Position
When you’re at the stage of making an offer, your sale and purchase agreement can sometimes include a due diligence clause. This generally gives you a set window of time to carry out checks, such as building and LIM reports, before the agreement becomes unconditional.
Every situation is different, and whether this kind of clause suits your purchase can depend on the property, the seller, and how competitive the market is at the time.
This is the kind of area where experienced property lawyers can often be useful. They may be able to help you understand what conditions could be appropriate for your circumstances, and what the reports you receive might mean for your position as a buyer.
How a Property Lawyer May Support You Through the Process
Buying property in New Zealand generally involves more than just agreeing on a price. A lawyer typically reviews the sale and purchase agreement, checks the title, and helps make sure any conditions, including those relating to building and LIM reports, are appropriately worded.
If a building report does flag potential weathertightness concerns, a lawyer may be able to help you understand your options. Depending on individual circumstances, this could include discussing a price adjustment, requesting further investigation, or withdrawing from the agreement if it’s still conditional.
Families and couples working with property lawyers in Auckland and NZ often find it reassuring to have someone independently looking at the legal side of the purchase, particularly when a property has features that raise questions.
Conveyancing: What Generally Happens Once You’re Ready to Proceed
Once you’re satisfied with your due diligence and ready to move forward, the conveyancing process typically begins. This can cover the legal transfer of ownership, including title checks, liaising with your lender, preparing settlement documents, and helping funds and paperwork move correctly around settlement day.
A conveyancing lawyer may also flag anything unusual on the title, such as easements, covenants, or historical consents, that could be relevant to a property’s history. This step can involve several weeks of preparation, so starting the process reasonably early may help things run more smoothly.
What Sellers May Want to Consider Around Disclosure
If you’re selling a home, being upfront about known issues, including any past weathertightness claims or repairs, is considered a sensible approach. Sellers are typically expected to disclose known defects, and a lawyer may be able to help you understand what information you’re required to provide and how to present your property’s history.
This isn’t only about meeting requirements. Buyers who feel more informed about a property’s history may sometimes feel more comfortable moving forward, which can potentially help a sale progress with fewer complications for everyone involved.
Looking at Commercial or Investment Property Instead?
Similar due diligence principles can apply beyond residential homes. If your search extends to investment or business premises, a commercial property lawyer may be able to help you navigate some of the additional considerations that can come with those transactions, such as lease terms and different disclosure requirements.
Moving Forward with Confidence
Leaky homes are part of New Zealand’s building history, but with the right checks in place, they don’t need to be a source of fear. A thorough building report, a LIM report, a well-considered due diligence clause, and good legal advice may go some way toward helping you approach a purchase with more confidence.
Every property and every purchase is different, so there’s no single approach that suits everyone. If you’re weighing up a purchase and want to talk through your options, the team at Land Law may be able to help guide you through the legal side of buying, selling, or refinancing a home in New Zealand.
