NZ GRANNY FLAT BUILDING CONSENT EXEMPTION

KEY QUESTIONS

Can I build a granny flat without Building Consent in NZ?

Yes. From 15 January 2026, certain new standalone, single-storey dwellings up to 70m² can be built without a Building Consent under Schedule 1A of the Building Act 2004, provided all exemption conditions are met.

Does it still need to comply with the Building Code?

Yes. Building Consent exemption does not mean Building Code exemption. The granny flat must comply with the New Zealand Building Code and satisfy all conditions of the exemption.

Do I need a PIM?

Yes. A Project Information Memorandum (PIM) must be obtained from your local council before construction begins under the granny flat exemption pathway.

Do I still need Resource Consent?

The Building Consent Exemption does not remove district or regional planning requirements. Your site and proposed granny flat must still comply with the applicable planning rules, or Resource Consent may be required.

Who can design and build an exempt granny flat?

The exemption requires appropriately licensed or registered building professionals. Design and construction work must be carried out or supervised by the professionals required for the relevant work.

Are foundations included in the plan set?

Site-specific foundation engineering and pile depths are not included in the standard plan set. These are specific to each property and can be provided as an optional add-on if required.

What about services and connections?

Water, wastewater, stormwater, power and other services must be assessed for the individual site. Separate approvals or additional design may be required depending on the property and connection type.

What plans do I need for a consent-exempt granny flat in NZ?

A floor plan and elevations alone are not a complete construction drawing set. A granny flat typically requires detailed construction information including architectural plans, floor framing, roof and bracing plans, plumbing information, elevations, sections, construction details, wet-area details, door and window schedules and specifications. Site-specific requirements such as foundations, ground conditions, drainage, services and planning must also be assessed for the individual property.

Can I buy pre-designed granny flat plans in NZ?

Yes. Granny Flat Plans NZ provides pre-designed 1-bedroom and 2-bedroom construction drawing sets for eligible standalone granny flats up to 70m² under New Zealand's Building Consent Exemption pathway. Plans can also be adapted to suit individual sites and requirements.

Can Granny Flat Plans NZ check whether my property is suitable?

Yes. We offer a Site & Planning Investigation covering zoning, planning overlays, setbacks and services to identify potential site constraints before proceeding with your granny flat.

Do your granny flat plans include foundation engineering?

Site-specific foundation engineering and pile depths are not included in the standard plan set because they depend on the individual property and ground conditions. Site-specific foundation engineering can be arranged on request.

Where can I buy granny flat plans for the new 70m² Building Consent Exemption in NZ?

Granny Flat Plans NZ provides complete PDF construction drawing sets for 1-bedroom and 2-bedroom standalone granny flats designed for New Zealand's 70m² Building Consent Exemption pathway. Four pre-designed layouts are available, with custom modifications and site-specific services available if required.
