Granny flat rules are changing: What it means for Kiwi homeowners
Thinking of adding a granny flat or secondary dwelling to your property? With new legislation set to take effect in early 2026, now is a smart time to start planning.
Here’s what you need to know about the new rules, what they mean for you, and how Ezyline Homes can help bring your plans to life.
What’s Has Changed?
In October 2025, the New Zealand Government passed the Building and Construction (Small Stand-Alone Dwellings) Amendment Bill to make it easier and more affordable to build a granny flat on your property.
Removing much of the red tape around resource consent, these legislative changes have been designed to simplify the approval process – especially for homeowners with underutilised land.
What Can You Build Without Consent?
Once the changes come into effect in 2026, homeowners will be able to build a new, standalone granny flat of up to 70m² without needing a full resource consent, as long as key conditions are met:
- Maximum 70m² floor area
- Single-storey only
- Must be a new, standalone building
- Constructed using lightweight materials (e.g. timber framing, steel roofing)
- Built on compliant foundation systems (timber or screw piles)
- Plumbing, electrical, and gas work must be done by licensed tradespeople
- Built or supervised by a Licensed Building Practitioner (LBP)
- Smoke alarms, heating, and utilities required
- Must meet all New Zealand Building Code requirements
- Set back at least 2 metres from any boundary or existing structure
These rules make it significantly easier to build a granny flat, sleepout, or minor dwelling to accommodate extended family, generate rental income, or create flexible living arrangements.
When Do the New Rules Take Effect?
The legislation has passed but won’t come into force until early 2026. Until then, the existing regulations still apply – including the need for building consent and council approvals. If you’re planning to build before then, you’ll need to follow the current process.
Council Notifications Still Required
Even under the new rules, there are still some important administrative steps:
- Before construction begins, you’ll need to apply for a Project Information Memorandum (PIM) from your local council.
- After the build is completed, you’ll need to notify the council again.
- Development contributions may still apply in some areas, so it’s worth checking with your local council for site-specific requirements.
What’s Not Included
The new rules do not allow:
- Multiple units on a single site under this exemption
- Subdivision of land
- Multi-storey builds
- DIY builds without a Licensed Building Practitioner involved
If you’re unsure whether your project qualifies, it’s best to seek professional advice early.
Strategic Opportunities for Homeowners
The new regulations open up exciting possibilities for many Kiwi homeowners. Whether you’re thinking about:
- Creating a home for adult children or ageing parents
- Adding a source of rental income
- Increasing the value of your property
…a compliant, transportable granny flat could be a smart, long-term investment. Just make sure to check your property’s zoning and boundaries to ensure eligibility under the new rules.

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.

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.
Purpose of the home
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.
The size of the Home
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.
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.
The flow of the home
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.

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.

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.
