Buying a house and land package in New Zealand can turn into a nightmare if hidden defects surface after the sale. Open homes usually present properties in their best light, obscuring potential problems. Therefore, thorough investigation beyond surface appearances is crucial to protect your investment. This article delves into the specific areas to scrutinize and the resources available to uncover hidden defects before you commit.
Pre-Purchase Building Inspections: Your First Line of Defense
A pre-purchase building inspection is arguably the most vital step in uncovering hidden defects. This isn’t just a cursory glance; it’s a detailed examination by a qualified professional. The New Zealand Standard NZS 4306:2005 outlines the scope and limitations of property inspections, so ensure your inspector adheres to these guidelines. A good inspector will assess the property’s structural integrity, checking for issues like foundation problems, timber rot, dampness, and pest infestations. They will also examine the roof, plumbing, and electrical systems. Keep in mind that finding an inspector covered by professional indemnity insurance may offer additional security. Consider checking qualifications of potential inspectors with the New Zealand Institute of Building Surveyors NZIBS.
What to Look for in a Building Inspection Report: The report should be comprehensive and easy to understand. Avoid reports that use vague language or disclaimers extensively. Look for clear descriptions of any defects found, their severity, and potential consequences. A good report will also offer recommendations for further investigation or repairs. Pay close attention to sections on:
- Subfloor: Difficult to access, this area often holds clues about moisture problems, borer infestations, and foundation issues.
- Roof: Leaks, damaged tiles or shingles, and issues with the roof structure can be costly to repair.
- Cladding: Problems with cladding systems, especially monolithic cladding, can lead to weathertightness issues and significant damage.
- Plumbing: Leaking pipes, poor drainage, and outdated plumbing can cause water damage and health problems.
- Electrical: Faulty wiring, overloaded circuits, and non-compliant installations pose serious safety risks.
The Cost of Ignoring a Building Inspection: Consider a case study: A buyer in Auckland purchased a house without a building inspection to save a few hundred dollars. After moving in, they discovered significant rot in the subfloor, estimated to cost $20,000 to repair. This could have been avoided with a thorough inspection. While building inspections generally cost between $500 to $1000, depending on the size and complexity of the property, failure to get one can potentially cost you far more than this amount in unexpected repair costs.
Weathertightness Issues: The Dreaded Leaky Home Syndrome
Weathertightness, or the lack thereof, has been a major issue in New Zealand construction, particularly with homes built between the early 1990s and mid-2000s. The use of monolithic cladding systems without proper detailing or ventilation led to many leaky buildings, resulting in extensive rot and structural damage. Even if a house doesn’t appear to have monolithic cladding, it’s still crucial to check for signs of moisture ingress. Look for:
- Staining or discoloration: Around windows, doors, and cladding joints.
- Bubbling or peeling paint: A sign of moisture underneath the surface.
- Musty odors: Indicating mold growth.
- Soft or spongy areas: In walls, floors, or ceilings.
Specific Cladding Types to Be Wary Of: While not all monolithic cladding systems are problematic, some have a higher risk of failure. These include:
- Polystyrene cladding: Can be vulnerable to moisture if not properly installed and sealed.
- Fibre cement cladding: If not detailed properly, it can become waterlogged and cause rot.
If you suspect a property has a potentially problematic cladding system, engage a specialist weathertightness expert to conduct a more in-depth assessment. Consider using the services of a building surveyor who specialises in moisture testing. This typically involves invasive and non-invasive moisture detection. The cost for a specialist weathertightness report can range from $800 to $2000, depending on the scope of the inspection.
The Importance of a Moisture Test: A moisture test uses specialized equipment to measure the moisture content of building materials. This can reveal hidden leaks and dampness that are not visible to the naked eye. If the moisture content exceeds acceptable levels, it indicates a potential problem that needs further investigation.
Checking the LIM and Title: Unearthing Council and Legal Issues
The Land Information Memorandum (LIM) and Certificate of Title are two essential documents to review before buying a property. These documents provide valuable information about the property’s history, zoning, and any potential issues that could affect its value or usability.
Land Information Memorandum (LIM): This report is obtained from the local council and contains information about:
- Building Consents: Details of any building work that has been approved or carried out on the property, including whether it has final sign-off.
- Resource Consents: Information about any resource consents that have been granted or applied for, such as subdivisions or alterations to the land.
- Special Land Features: Information about potential hazards, such as flooding, erosion, or contamination.
- Rates Information: Details of the property’s current rates and any outstanding amounts.
- Zoning and Planning Information: Information about the property’s zoning and any future development plans that could affect it.
Interpreting a LIM Report: Carefully review the LIM for any red flags. For example, if there are outstanding building consents for alterations, it means the work may not have been completed to code and could be unsafe. If there are resource consents for nearby developments, it could impact the property’s views or privacy. The cost of a LIM ranges from $300-$500 and this cost is insignificant beside the expenses that could incur if issues are ignored.
Certificate of Title: This document provides legal ownership details and outlines any encumbrances on the property, such as:
- Mortgages: Any existing mortgages on the property.
- Easements: Rights of way or access granted to other parties.
- Covenants: Restrictions on how the property can be used or developed.
- Caveats: Notices that someone else has an interest in the property.
Understanding Title Encumbrances: Easements can affect your ability to build on certain parts of the property. Covenants can restrict the type of alterations or additions you can make. Caveats can indicate a dispute over ownership or a claim against the property. It’s crucial to understand the implications of any encumbrances before buying the property. Reviewing the title with your lawyer is generally a must before completing any purchase. Engaging a lawyer to check for legal issues is often the most important aspect of this step despite being the most overlooked.
Pest Infestations: The Silent Destroyers
Pest infestations, particularly by wood-boring insects like borer, can cause significant damage to a property’s structural integrity. Borer larvae feed on timber, weakening it over time. Signs of borer infestation include:
- Small holes in timber: These are exit holes where adult borers have emerged.
- Dust or frass: Fine powder that is expelled by borers as they eat the timber.
- Weak or crumbling timber: Indicating that the timber has been extensively damaged.
Getting a Pest Inspection: A pest inspection is a specialized inspection conducted by a qualified pest control technician. They will inspect the property for signs of borer, termites, and other pests. They will also provide a report outlining any infestations found and recommendations for treatment. A pest inspection typically costs between $200 and $500.
Treating Borer Infestations: There are various methods for treating borer infestations, including:
- Surface spraying: Applying insecticide to the surface of the timber.
- Injection: Injecting insecticide directly into the borer holes.
- Fumigation: Sealing the property and fumigating it with insecticide (for severe infestations).
The cost of treatment will depend on the extent of the infestation and the method used.
Drainage and Plumbing: Avoiding Water Damage Nightmares
Poor drainage and plumbing can lead to a range of problems, including water damage, dampness, and mold growth. It’s crucial to check the property’s drainage and plumbing systems to ensure they are functioning properly. Look for:
- Water pooling around the foundation: Indicating poor drainage.
- Dampness in the basement or subfloor: A sign of water ingress.
- Leaking pipes or faucets: Wasteful and can cause water damage.
- Slow drains: Indicating a blockage.
- Discolored water: A sign of corrosion in the pipes.
Checking the Drains and Gutters: Make sure the drains and gutters are clear of debris. Blocked drains and gutters can cause water to overflow and damage the property. Check for any signs of rust or corrosion in the gutters. Consider asking the vendor for copies of invoices for recent plumbing maintenance.
Investigating Septic Systems (if applicable): If the property has a septic system, ensure it is in good working order. Septic systems require regular maintenance, and a failing system can cause environmental and health problems. Have the septic system inspected by a qualified technician.
Asbestos: The Hidden Health Hazard
Asbestos was commonly used in building materials in New Zealand until it was banned in 2016. If the property was built before this date, there is a risk that it contains asbestos. Asbestos fibres are dangerous when inhaled and can cause serious health problems, including lung cancer and mesothelioma. Only a laboratory test can confirm asbestos, so if you suspect its presence consider a professional opinion about getting it tested.
Where Asbestos Might Be Found: Asbestos was commonly used in:
- Fibro cement sheeting: Often used for exterior cladding, wall linings, and ceilings.
- Roofing: Asbestos cement roofing sheets and shingles.
- Insulation: Pipe insulation and lagging.
- Vinyl flooring: Asbestos backing in vinyl tiles and sheet flooring.
- Textured ceilings and walls: Also known as ‘popcorn’ ceilings.
Managing Asbestos: If you suspect a material contains asbestos, do not disturb it. Damaging or removing asbestos materials can release fibres into the air. Engage a qualified asbestos professional to inspect and sample suspect materials. If asbestos is present, it should be managed according to the WorkSafe New Zealand guidelines WorkSafe New Zealand. An asbestos survey can cost between $500 to $800 and this cost is insignificant compared to the health risks involved.
Methamphetamine Contamination: A Growing Concern
Methamphetamine contamination is a growing concern in New Zealand properties. If a property has been used for manufacturing or smoking methamphetamine (‘P’), it can leave behind residues that pose a health risk. While it is usually very difficult to visibly detect, here are the signs:
- Unusual chemical odors: especially if they are strong and lingering.
- Staining on walls or ceilings: usually yellow or brown in colour.
- Modified ventilation systems: if ventilation or exhaust systems have been modified without permits.
Although the previous occupants may have covered their tracks, it is worth enlisting professionals. Check with the Real Estate Authority for additional information on disclosing if a home has been contaminated by methamphetamine.
Testing for Methamphetamine: A methamphetamine test can determine the level of contamination in a property. There are two types of tests:
- Composite test: A quick and inexpensive test that takes samples from multiple locations.
- Individual test: A more detailed test that takes samples from specific areas of concern.
The acceptable level of methamphetamine contamination in New Zealand is 1.5 micrograms per 100 cm². If contamination exceeds this level, remediation is required.
Remediation: Methamphetamine remediation involves cleaning and decontaminating the property to remove the residues. This can be a costly and disruptive process. It’s important to engage a qualified remediation company to ensure the job is done properly.
Checking for Unconsented Work: Ensuring Compliance
Any structural work, plumbing, or electrical installations require a building consent from the local council. Carrying out unconsented work can result in fines, legal issues, and problems when selling the property. To check if work was completed correctly, you can:
- Review the LIM report: check for any records of building permits issued for the property.
- Compare existing structures: compare them with building plans held by the council.
- Look for inconsistencies: check for any structures without proper foundations or supporting walls.
Geotechnical Issues: Land Stability and Potential Risks
New Zealand’s unique geography makes some areas prone to geotechnical issues like landslides, subsidence, and liquefaction. These risks are especially relevant if you are planning to develop or expand the land yourself. If there are nearby signs that land could be at risk, you can:
- Consult the local council: councils often have data on local geo hazards.
- Check with GNS science: GNS Science provides data on geological hazards, including fault lines.
- Assess the land around: evaluate nearby areas for signs of soil movement or past instability.
Neighbourhood Issues: Boundary Disputes and Noisy Neighbors
It’s possible to ascertain issues related to neighbors prior purchasing a property. Conduct due diligence by visiting at various times—day and early evening to check noise levels. Consider knocking on doors of neighboring properties to make casual inquiries about the neighborhood dynamics. It is worth looking into online local community groups, which sometimes discuss ongoing neighbor conflicts. It’s important to note that while these conversations can yield insights, it’s crucial to take such information as only one factor of your considerations as they may be subjective.
Negotiating the Purchase Agreement: Protecting Your Interests
Your purchase agreement is a legally binding contract, so it’s critical to ensure it protects your interests. Include the following clauses to safeguard yourself:
- Subject to Building Inspection Clause: Allows you to cancel the agreement if the building inspection reveals unacceptable defects.
- Subject to LIM Clause: Allows you to cancel the agreement if the LIM report reveals unacceptable issues.
- Subject to Finance Clause: Allows you to cancel the agreement if you are unable to obtain finance.
Getting Legal Advice: Engage a lawyer to review the purchase agreement and provide legal advice before you sign it. A lawyer can ensure that the agreement protects your interests and that you understand your rights and obligations.
Making an Offer: Don’t be afraid to negotiate the purchase price. If the building inspection reveals defects, you can use this as leverage to negotiate a lower price or to have the vendor repair the defects before settlement.
Keep track of every expense from inspections, lawyers’ fees, bank fees, and relocation.
FAQ Section
What happens if I find a major defect after I’ve purchased the property? Unfortunately, your options may be limited. You may have a claim against the vendor if they misrepresented the property or failed to disclose known defects. However, pursuing legal action can be costly and time-consuming, which is why a thorough pre-purchase inspection is so important.
Can I rely on the vendor’s disclosure statement? The vendor’s disclosure statement provides important information about the property, but it’s not a substitute for your own due diligence. The vendor may not be aware of all the defects in the property. Always conduct your own independent investigations.
What are some red flags I should look for during an open home? Be aware of:
- Fresh paint covering up stains or damage.
- New carpets masking floor problems.
- Strong air fresheners masking musty odors.
- Cracks in the walls or ceilings.
- Uneven floors.
Is it worth getting multiple building inspections? Generally, one comprehensive building inspection by a qualified professional is sufficient. However, if you have concerns about a specific area of the property, such as weathertightness or pest infestation, you may want to engage a specialist inspector. Consider engaging with a building surveyor who may be able to give a more well-rounded opinion.
How recent should the inspection reports be prior to the purchase? Ideally, get the inspections done closer to the purchase date as possible but it should not exceed six months.
