Kiwis will soon have an easier path to adding extra housing on their properties. As of today, homeowners can build granny flats up to 70 square metres without the need for resource or building consents, though the changes are subject to specific conditions.
Easing the Housing Pressure
Housing Minister Chris Bishop announced the changes alongside other ministers at a development in Auckland’s Riverhead, showcasing a 65 square metre minor residential unit. Bishop stated the new rules aim to provide “more flexibility” and contribute to addressing the country’s ongoing housing crisis. However, he cautioned that the changes are “not a complete free-for-all.”
Granny flats constructed under the new rules must adhere to a simple design and meet all requirements of the Building Code. All work must be completed or overseen by licensed building professionals. Councils will also be informed when a granny flat is planned, though this notification does not grant them the power to veto the construction.
Conditions and Considerations
Minister Bishop emphasized that several rules apply, including site-to-boundary coverage limitations. Building and Construction Minister Chris Penk added that the same restrictions governing standard dwellings will apply to granny flats, prohibiting construction in areas prone to flooding where houses are currently restricted.
The government estimates the reforms could save homeowners up to $5600 in direct costs and reduce the building timeline by approximately 14 weeks, though these figures will vary depending on location. This policy fulfills a commitment made as part of the coalition agreement between National and its partners.
Minister Penk believes the changes will benefit a range of groups, including students, seniors, and those working in rural areas, and will provide a boost to the construction industry. He also noted that, due to the dispersed nature of the policy – one granny flat per existing property – the impact on council water services is expected to be minimal.
The Ministry of Business, Innovation and Employment has published guidance and templates on its website to assist homeowners, councils, and building professionals with the new regulations. This includes information on responsibilities and key considerations before construction begins.
