Can I Have a Granny Flat on my Property in NZ? Rules, Options & Benefits
One of the most common questions that comes through our inbox is “can I have a granny flat on my property?”
And while the answer is usually yes, it will always depend on your site, how the home is built, and your council. What’s allowed in one part of New Zealand isn’t necessarily the case in another (as frustrating as that might be).
So, whether you need space for extended family or are looking at rental opportunities, it pays to understand the rules and your options before you commit.
Legal Requirements & Council Rules
In New Zealand, a granny flat is usually a self-contained “secondary dwelling” located on the same site as an existing house. Thanks to recent changes in law, if you meet exemption criteria you can now build a granny flat up to 70m² without a resource or building consent, but it does still need to be built by LBPs and in line with local council requirements.
Zoning rules can affect how big the dwelling can be and where it can sit on the site. So it’s still best to speak directly with your council before starting the process.
Design & Site Considerations
Beyond the rules, there are practical factors that will impact what can be built on your site.
It’s worth thinking about privacy between the main dwelling and the granny flat, access to sunlight, and how services such as water, wastewater, and power will connect. The orientation of the building can improve comfort and energy efficiency, while careful placement helps both homes feel independent.
Access is another key factor, especially if you’re considering something built off-site. You’ll need sufficient driveway width and turning space for delivery and installation, or for awkward sites it might be worth considering a narrow granny flat.

Traditional Build vs Transportable Granny Flat
In terms of building a granny flat, you can use traditional on-site construction or choose a transportable option.
A conventional build will involve longer timeframes, more trades (and disruption) on site, and exposure to weather delays. A transportable granny flat is built in a controlled environment before being delivered and installed once the foundations are ready.
For many homeowners, that shorter timeline and predictable process make the whole process much less stressful. Learn more about the benefits in Why Choose Transportable Homes, or see the quality for yourself by booking a visit to our show homes.

Buying a transportable home is a big decision. Whether it’s for your main residence, a holiday retreat, worker accommodation, or a secondary dwelling, there are several moving parts to consider beyond just the floor plan.
If you’ve been researching what to look for when buying a transportable home, this is our checklist to help you make an informed choice.
Site Suitability & Access
Before falling in love with a layout, start by investigating whether your site is suitable for a transportable build. Rural and urban sites present different challenges. Narrow driveways, tight turning circles, overhead power lines, or limited access can all influence delivery.
An early site assessment gives your transportable home builder a chance to determine if there are any restrictions to the type of home that will work for your property.
Learn more about what’s involved in the transport and installation phase in our Transportable Homes Delivery Process.
Build Quality, Materials & NZ Compliance
Transportable homes have to comply with the New Zealand Building Code, just like any other residential build. That includes things like structural durability, insulation standards, moisture management, and seismic considerations.
Builds completed in a controlled environment have advantages because construction happens under predictable conditions, allowing for tighter tolerances and greater consistency when installing elements such as insulation and glazing.
When comparing your options, take into account the factors that make for a comfortable home - insulation, glazing, weather performance, and overall longevity of the materials being used.

Design Flexibility & Lifestyle Fit
Whether you’re looking for a primary residence, a holiday retreat, or accommodation for workers, considering the right layout based on how you’ll use the home will make the biggest difference to how the property is enjoyed.
The intended use of your home significantly influences the features and layout you should prioritise. Here are a few common purposes:
Additional accommodation for extended family: If the home will serve as extra space for family members, consider their comfort and privacy. Features like multiple bedrooms, a separate bathroom, and a cosy living area can make the space more inviting.
Holiday home: For a holiday property, prioritise low-maintenance features, easy access to outdoor areas, and amenities that enhance relaxation, such as a deck and outdoor living spaces.
Worker accommodation: Practicality and durability are key for worker housing. Ensure the home is equipped with sufficient amenities, durable materials, and adequate space for comfortable living.
Granny flat: Usability and preparing for the future are key considerations. If the person using the home is advanced in years, we can prepare the home by making doors flush entry, putting timber in the walls for future grab rails and making doorways wider for future wheelchair access.
Purpose of the home
While many transportable, modular, prefab, and kitset homes come in a range of sizes and orientations, often a more customised approach is necessary to achieve the perfect layout for your needs.

Number of bedrooms
The number of bedrooms is a fundamental consideration when selecting a transportable home. Think about your current and future needs. If you have a growing family or anticipate hosting guests, opting for additional bedrooms can provide comfort and flexibility. Even if the home is intended as a holiday retreat or worker accommodation, having extra rooms can enhance privacy and convenience.
Number of bathrooms
Bathrooms are another important factor, particularly in homes with multiple occupants. A second bathroom can be a game-changer, reducing morning rush hour stress and providing privacy. Consider the number of people who will use the home regularly and whether additional bathrooms are necessary to meet their needs.
Separate laundry area
A dedicated laundry area is a practical feature that many overlook. A separate laundry room can help keep the rest of the home organised and clutter-free. Whether you're washing beach towels from a day at the holiday home or uniforms in a worker accommodation setting, a designated laundry space adds convenience and functionality.
Customisable layouts
The ability to pick your preferred finishes including paint colours, floor coverings, joinery, and appliances is an easy way to help make your transportable home feel like your own. Customising the orientation of your floorplan to suit your needs goes a long way in helping to make your transportable home tick all the boxes when a standard floor plan doesn’t quite fit the bill.
Whether you’re looking to prioritise open plan living, need plenty of accommodation for all the extended family, or storage is top on your list, considering a floor plan which is tailored to include all the amenities you need is an important consideration to ensure your transportable home fits your lifestyle for years to come.
Living area size
The living area is the heart of any home, where family and friends gather to relax and socialise. The size of the living area should align with your lifestyle and how you plan to use the space. For those who love entertaining, a larger living area may be ideal. Conversely, if the home is a secondary residence or for temporary use, a more compact living space might suffice with the extra floor plan used for additional bedrooms or storage.
Kitchen and dining area
The kitchen and dining area are crucial spaces for daily living. Consider the size and layout of the kitchen, especially if you enjoy cooking. A well-designed kitchen with ample counter space, storage, and modern appliances can make meal preparation a pleasure. The dining area should comfortably accommodate the number of people you expect to dine regularly.
Storage space
Lack of storage is often a pain point in any home. Evaluate the available storage options, including closets, cabinets, and potential external storage like sheds or garages. Ample storage helps keep the home organised and clutter-free, contributing to a more pleasant living environment.
Outdoor space
Outdoor space can significantly enhance your enjoyment of a transportable home, especially in a holiday setting. Consider features like a deck or patio. These spaces provide a great spot for outdoor dining, relaxation, and enjoying nature.

The Build & Delivery Process
One of the biggest differences between a traditional build and a transportable home is where the work happens.
Instead of months of on-site activity, your home is constructed in a controlled environment before being transported and installed on prepared foundations. Timelines can vary depending on a few different factors, but these builds allow more certainty in scheduling and are less likely to run over.
While many transportable, modular, prefab, and kitset homes come in a range of sizes and orientations, often a more customised approach is necessary to achieve the perfect layout for your needs.
