He Tiwhikete whakaae mahi hanganga kāhore i whakaaetia Certificate of Acceptance (CoA) for unconsented building work

A Certificate of Acceptance (CoA) is proof that building work done without consent meets the New Zealand Building Code. However, it does not have the same value as having an approved building consent. 

Eligibility for a CoA

You can apply for a CoA only if building work was constructed without a building consent from 1 July 1992 onwards, or in specific circumstances, when a Code Compliance Certificate (CCC) cannot be issued.

A CoA may be issued for building works in the following circumstances:

• when urgent work is carried out to protect life or health, or prevent serious damage to property, and it is not practical to obtain a building consent in advance
• when a building consent authority (that is not a territorial authority or regional authority) or an organisation accredited to the BCA regulations is unable or refuses to issue a CCC for work carried out under a building consent.

Before you apply for CoA

Before you apply for a CoA, we recommend you apply for and attend a CoA pre-application meeting. This is not mandatory but is recommended.

The purpose of the meeting is to determine whether:

• a Project Information Memorandum (PIM) is required (this document contains planning and building advice)
• a building consent is required (note that some building work is exempt from requiring a building consent under Schedule 1 of the Building Act)
• resource consent is required (all work must comply with the Unitary Plan. We recommend getting the resource consent first if it is required).
• the building work is likely to obtain approval.

CoA for unconsented work before 1 July 1992 

We cannot issue a CoA for building work completed without approval before 1 July 1992. Any work before this date was done according to the old building bylaws and the building permit system. 

 You can choose to:

• remove the unconsented building work and rebuild after getting a building consent:
  • refer to schedule 1 of the Building Act 2004 to check if you need a building consent to remove the building
  • refer to the Auckland Unitary Plan to find out if you need a resource consent
• get a report from an independent expert.
