Granny Flat & Minor Dwelling Regulations in New Zealand
Introduction
Granny flats and minor dwellings are becoming increasingly popular across New Zealand as homeowners look for flexible ways to add extra living space to their property.
Whether you are planning to build accommodation for family members, create rental income, or add value to your property, it is important to understand how granny flats are regulated.
Rules can vary depending on council planning regulations, building consent requirements and how the home is designed.
Below is a general guide to how granny flats and minor dwellings are typically regulated in New Zealand.
What Is a Granny Flat?
A granny flat is a small, self-contained home built on the same property as an existing house.
In New Zealand, these homes are often referred to as:
• minor dwellings
• secondary dwellings
• small homes
Most granny flats include:
• a kitchen
• bathroom
• bedroom
• living area
They are commonly used for:
• family members or aging parents
• adult children
• guest accommodation
• rental income
What Is a Minor Dwelling?
A minor dwelling is a planning term used by many councils to describe a second small home built on a residential property.
Minor dwellings typically:
• are smaller than the main house
• share the same property title
• must comply with local council planning rules
Depending on the council, there may be limits around:
• floor area
• site coverage
• location on the property
• parking requirements
Do Granny Flats Require Building Consent?
Some granny flats require building consent, particularly when they include plumbing, drainage and electrical connections.
Building consent ensures that the home meets the requirements of the New Zealand Building Code.
However, building rules for small homes continue to evolve, and there are proposals aimed at making it easier to build small standalone homes under certain size limits.
Because of this, it is important to confirm current requirements with your local council or builder before starting a project.

Can You Build a Second Dwelling on Your Property?
In many cases, it is possible to build a second small dwelling on your property, but it depends on factors such as:
• zoning rules
• property size
• site coverage limits
• council planning regulations
Some properties are well suited for a second dwelling, while others may require planning approvals or design adjustments.
