Rules and Conditions Under the New Granny Flat Consent Exemption Law
When an elderly relative needed extra care, one family in Auckland realised their main home was simply too small. They wanted to stay close but faced the overwhelming cost of council fees and months of building delays. This story is very common across New Zealand. For years, adding a minor dwelling felt like an impossible dream for many homeowners. However, a major shift has finally arrived to solve this housing pressure.
As of January, 2026, the government has officially enacted a law that removes the need for building and resource consents for a Granny Flat up to 70 square meters. According to the official announcement, this change aims to provide affordable housing solutions by cutting through the red tape that once blocked simple, standalone units.
At Seaview Projects, we know this is a massive opportunity for your property.
Key Points
- Standalone units up to 70 square meters are now exempt from building and resource consents.
- All builds must still strictly follow the New Zealand Building Code.
- You must use Licensed Building Practitioners (LBPs) for the construction.
- You are required to notify your local council before and after construction.
- Development contributions and utility connection fees still apply.
What is a Granny Flat Under the New 2026 Regulations?
The new rules define a granny flat as a new, standalone, single-storey dwelling that is 70 square meters or less in floor area. Unlike previous proposals that capped these units at 60 square meters, the final law allows for a bit more room to breathe. These units are intended for single households and can include full amenities like a kitchen and bathroom. Even with the exemption, you still have to meet the New Zealand Building Code. This ensures your unit is safe, dry, and healthy for your family or tenants.
We know you might want more than just a basic shed in the backyard. That is where a smart granny flat comes in. These modern units use high-efficiency designs and technology. They make a smaller space feel like a luxury home. You might need a space for your parents or a rental unit for extra income. We have the expertise to bring your vision to life. We are a premier construction and landscaping company in Auckland. Our work will exceed your expectations.
Is a Smart Granny Flat the Right Fit for Your Auckland Property?
Deciding to build a smart granny flat is a big step. These units are perfect for modern living because they use space-saving layouts and energy-efficient systems. As the new law allows for units up to 70 square meters, you can actually fit two small bedrooms or a very spacious one-bedroom layout. This adds significant versatility to your land.
If your property isn't quite right for a standalone unit, you might explore home extensions instead. While the new 70-square-meter exemption only applies to detached units, we can help you compare your options. We pride ourselves on being a trusted partner. We manage projects from start to completion, ensuring you get the best return on your investment. If you decide to go with a standalone build, a smart granny flat can offer complete independence from the main house.
What are the Mandatory Conditions for the Consent Exemption?
You cannot simply start building tomorrow without any oversight. To qualify for the exemption, you must follow a specific legal process. Failing to do so could result in fines or issues when you eventually try to sell your home.
Project Information Memorandum (PIM): You must apply for a PIM from your local council before any work begins. This identifies risks like flooding or heritage restrictions.
Professional Oversight: All restricted building work must be carried out or supervised by Licensed Building Practitioners (LBPs).
Simple Design: The exemption applies to "simple" designs. This typically involves lightweight materials for the roof and frame.
Distance Rules: Your unit must be at least 2 meters away from the main residential building and any legal boundaries.
Final Notification: Once the build is finished, you have 20 working days to provide the council with final plans, Records of Work, and certificates of compliance.
We handle these technical details for you. We are a locally owned and operated business that specialises in residential construction and maintenance. We ensure your granny flat meets every requirement of the Building Code while you relax and watch the progress.
Should You Combine the Build with a Kitchen Renovation in Auckland?
Many of our clients find that building a new unit is the perfect time to upgrade their primary residence. While our team is on-site, you might consider a kitchen renovation for your main house. This allows you to modernise your entire property at once. A fresh, modern kitchen can increase your home's value just as much as a new backyard dwelling.
If you aren't sure which project to prioritise, we can help you create a master plan. Our skills extend to both indoor transformations and outdoor spaces. Whether it is professional landscaping around your new unit or a full kitchen renovation in Auckland, we are here to help. We believe in quality craftsmanship and attention to detail in every corner of your property.
How Do the New Rules Impact Home Extensions in Auckland?
You need to remember something important about home extensions in Auckland. They do not fall under this specific consent exemption right now. Do you want to add a room that connects to your main house? You will still likely need to go through the traditional building consent process. The new law is made specifically for detached, minor residential units.
However, we have the expertise to manage the consent process for your extensions if that is the better path for your site. We serve our local community with integrity and will always tell you which option is the most cost-effective. Sometimes a standalone smart granny flat is better for privacy, while an extension is better for keeping the family under one roof. We help you weigh these pros and cons based on your unique needs.

Frequently Asked Questions
1. What happens if my land has natural hazards like flooding?
The exemption isn't a "free pass." If your land faces risks like flooding, you’ll likely still need a resource consent. This is why the mandatory PIM stage is so important. It allows the council to check if your site is safe for a new home.
2. Do I still have to pay development contributions to the council?
Yes. You'll save around $5,650 on building consent fees, but development contributions still apply. These funds local pipes and roads. In Auckland, these costs often range from $17,000 to $30,000, so please budget early.
3. Can I use the new 70-square-meter unit as a short-term Airbnb rental?
You can. You just need to follow your local council's specific bylaws. These larger units are excellent for rental income or guest stays.
4. Does the exemption mean I don't need a registered plumber or electrician?
No. All plumbing and electrical work must be done by authorised pros. You still need certificates of compliance to keep your building legal and insured.
5. Can I build a Granny Flat if there is already a minor dwelling on my site?
The new rules generally allow for one unit per property. If you already have a secondary dwelling, you might need a resource consent. We can help you check your site coverage limits.
