Here are our answers to some of the most commonly asked questions.
From early 2026 you’ll be able to build a single, self-contained granny flat or minor dwelling of up to 70m² without requiring a full building consent, provided it meets strict conditions and is carried out or supervised by licensed professionals. Our granny flats comply with the NZ Building Code.
Every granny flat we build is supervised by licensed builders, plumbers and electricians, with full compliance documentation provided. This includes Records of Work and Project Information Memoranda (PIMs) which simplifies the paperwork you need to notify your local council.
From early 2026, granny flats up to 70m² will be exempt from building consent, but you’ll still need to meet strict criteria and notify the council before and after construction.
Rental income depends on your location, access, finish quality, features and local rental demand. You may prefer long term tenants, or look to rent your property to tourists using a holiday rental platform such as Airbnb. Rental income for holiday lets can be impacted by seasonal demand.
The cost to build a granny flat in New Zealand can vary widely depending on size, finishes and site conditions, but typical budget for a Manor Build granny flat ranges from $180,000 to $300,000.
