Granny Flat Building Consent Exemption – Temporary PIM Process
From 15 January 2026, you may be able to build a Granny Flat (a single, small, self-contained standalone dwelling) without obtaining a Building Consent.
To build under this new exemption, the proposed granny flat must meet specific legislative criteria, and you are still required to apply for a Project Information Memorandum (PIM) before building work begins.
Information on planning requirements and exemptions under the NES for Detached minor residential units can be found here - Detached Minor Residential Units
Temporary PIM Application Process
Our building consent software provider (Objective Build) is currently upgrading the system to support applications for the new granny flat exemption.
Until this upgrade is complete, applicants must use the following temporary process:
- Apply for a standard PIM through the Objective Build Portal.
- As part of your PIM application, you must include the prescribed MBIE form for non-consented small standalone dwellings.
Required Form
Please download and complete the MBIE form below and upload it with your PIM application:

Important Notes
- This is a temporary application process and will change once the system upgrade is complete.
- A PIM does not confirm compliance with the exemption criteria. Applicants are responsible for ensuring all exemption requirements are met.
- We recommend seeking professional advice if you are unsure whether your proposal qualifies under the exemption.
- The proposed work must still comply with all other relevant legislation.
