When you're planning to extend your home, renovate, or build something new in Auckland, one of the first things you'll need to get familiar with is the building consent process. It might sound a bit daunting at first, but I’m here to break it down for you in a simple way. Knowing what to expect can save you time, stress, and even money.
What Is the Building Consent Process?
The building consent process is a set of steps you follow to get official approval before starting most types of building work. This approval ensures your project meets New Zealand’s building codes and safety standards. It’s not just a formality - it’s there to protect you, your family, and your investment.
Think of it like getting a green light from the council. Without it, you risk fines, having to undo work, or even legal trouble. The process involves submitting detailed plans and documents, which the council reviews carefully.
If you want to learn more about how to get started, Alder Homes offers great guidance on building consent.

Breaking Down the Building Consent Process
Let’s walk through the main steps you’ll encounter:
1. Preparing Your Plans
Before you apply, you’ll need detailed drawings and specifications of your project. These should show everything from the layout to the materials you plan to use. If you’re working with a builder or architect, they’ll usually handle this part.
2. Submitting Your Application
Once your plans are ready, you submit them to your local council. This includes forms, fees, and all the supporting documents. It’s important to double-check everything to avoid delays. These can be submitted by you, but we recommend having your builder or architect submit and manage the application on your behalf.
3. Council Review
The council will review your application to make sure it complies with the Building Code and other regulations. They might ask for more information or changes if something doesn’t meet the standards.
4. Approval and Consent Issued
If all goes well, you’ll receive your building consent. This usually takes about 20 working days after all the information has been received. This means you’re officially allowed to start work. Keep in mind, this consent usually has conditions you must follow.
5. Inspections During Construction
As your project progresses, council inspectors will visit to check that the work matches the approved plans and standards. These inspections are crucial to ensure safety and quality. Your builder will liaise with the council and book the inspections accordingly.
6. Final Sign-Off
After the work is complete and passes all inspections, you’ll get a code compliance certificate. This confirms your building work is legal and safe.

How Long Does Building Consent Take in NZ?
One of the most common questions I hear is, "How long does building consent take in NZ?" The answer depends on several factors:
Complexity of the project: Simple renovations might take a few weeks, while large new builds or complex extensions can take longer.
Quality of your application: If your plans are clear and complete, the council can process them faster.
Council workload: Some councils are busier than others, which can affect processing times.
Typically, you can expect anywhere from 20 to 30 working days for the council to process your application. If they need more information or if your project is complex, it might take longer.
To avoid delays, make sure your application is thorough and consider working with experienced professionals who know the ropes.

Tips for a Smooth Building Consent Experience
Navigating the building consent process doesn’t have to be stressful. Here are some practical tips to help you along the way:
Start early: Don’t wait until the last minute to prepare your application. Getting organized early can prevent headaches later.
Work with experts: Builders, architects, and planners who understand local rules can make the process much easier.
Communicate with your council: If you’re unsure about requirements, ask questions. Councils often have helpful resources and staff ready to assist.
Keep copies of everything: Save all documents, emails, and approvals. You’ll want these handy during construction and for future reference.
Plan for inspections: Schedule your work so inspections can happen on time. Delays in inspections can hold up your project.
Why Getting Building Consent Matters
You might wonder why all this paperwork and waiting is necessary. Here’s why it’s so important:
Safety: Ensures your home is safe and watertight for you and your family.
Legal protection: Avoids fines and legal issues down the track.
Resale value: Buyers want assurance that your home meets standards.
Insurance: Some policies require proof of consent for claims.
By following the process, you’re investing in peace of mind and the long-term value of your home.
