Building Consents: What You Need to Know and Why They Matter

What is building consent? 

A building consent for a renovation in New Zealand is a formal approval from the local council that allows a property owner to carry out specific construction or alteration work on their building/property. It ensures that the proposed renovation complies with the New Zealand Building Code, which sets out requirements for health, safety, durability, and energy efficiency.  

The consent process typically involves submitting detailed plans, specifications, and other necessary documentation to the local council. These documents are assessed to ensure the renovation work meets legal standards and is safe. Depending on the nature of the renovation, consent may be required for structural changes, plumbing, electrical work, or alterations to the building's use or appearance. Failing to obtain building consent can result in penalties, and the work may need to be undone or rectified. 

 

Do I need a tradie to do renovation work? 

Having a qualified tradesperson do renovations is crucial for several reasons. First, qualified professionals have the necessary skills, knowledge, and experience to ensure the work is done correctly, safely, and to a high standard. This helps prevent costly mistakes or poor-quality work that could lead to problems down the line.  

Second, many renovation tasks, such as electrical, plumbing, or structural work, require specialised expertise to comply with safety standards and building codes. A qualified tradesperson will ensure the work meets these legal requirements and may be able to help with obtaining the necessary building consent. Additionally, using a professional reduces the risk of accidents, as they are trained to handle tools and materials safely.  

Finally, having a qualified tradesperson can increase the value of the property, as buyers often prefer homes with renovations done by licensed experts, as this assures the quality and safety of the work. 

 

Consequences 

If you don't obtain building consent for a renovation or construction project in New Zealand, you may face several serious consequences: 

• Legal and Financial Penalties: Not having the required consent can result in fines or penalties imposed by your local council. This can be expensive and time-consuming to resolve. 
• Insurance Issues: Without building consent, your home insurance policy may not cover damage related to the unconsented work, leaving you financially vulnerable if something goes wrong. In some cases, your insurer may refuse to pay for repairs or damages resulting from non-compliant renovations. 
• Difficulty Selling the Property: If you later decide to sell your property, unconsented work may be flagged during inspections or when prospective buyers inquire about the property. This could reduce the value of your home, or prevent the sale altogether, as buyers may not want to deal with the legal and financial risks. 
• Required Rectification: If your local council discovers unconsented work, they may order you to undo or alter the renovations to bring them into compliance. This could be costly, time-consuming, and disrupt your living situation. 
• Safety Risks: Work done without proper consent may not adhere to safety regulations, potentially putting your home and its occupants at risk. This is particularly dangerous for electrical, plumbing, and structural work. 

In short, skipping building consent can result in significant legal, financial, and safety issues. It's always best to follow the correct process to ensure your renovations are legally compliant and safe.
