Multiproof Building Consents Listen What is a MultiProof Building Consent? The MultiProof service came into effect on 1 February 2010. It enables volume builders to obtain a MultiProof or National Multiply-Use approval for standardised building designs that are intended to be replicated several times. A MultiProof is a statement issued by the Department of Building and Housing. It confirms that a specific set of building plans and specifications complies with the NZ Building Code. A MultiProof does not replace a Building Consent. You must each time, still apply and obtain a Building Consent if you are a holder of a MultiProof. To apply for a MultiProof Building Consent, you will need to complete the Building Consent/PIM Application Form. The Council will assess the Building Code compliance for site specific features that are excluded from the MultiProof only. For this reason, the Council has 10 working days to grant or refuse to grant the Building Consent. Who can apply for a MultiProof? To find out how to apply for a MultiProof, please contact the Department of Building and Housing.
