Certificate of acceptance (CoA) for unconsented building work
He Tiwhekete whakaae mahi hanganga kāhore i whakaaetia
A CoA provides a limited assurance that we are satisfied, on reasonable grounds, that unconsented building work complies with the current New Zealand Building Code.
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) can't be issued.
A CoA may be issued for building works in the following circumstances:
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 code compliance certificate for work carried out under a building consent.
Before you apply for CoA
Before you apply for a Certificate of Acceptance (COA) you need to attend a CoA pre-application meeting.
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. If resource consent is required then this must be obtained first)
- the building work is likely to obtain approval.
Request a CoA pre-application meeting
To request a CoA pre-application meeting, visit our

When we confirm your CoA pre-application meeting, we may request additional information or documents. You should provide these at least three working days before the meeting.
Application fees for CoA
You must pay the fixed fee plus the deposit at the time you lodge your application.

What you need to provide
You may need to provide evidence, usually from a professional, to help us assess how the work complies with the current New Zealand Building Code, particularly for building work we cannot inspect, such as foundations.
You can apply for a CoA for all or part of a building.
Return the completed form with any supporting material by post to:
Private Bag 92300
There may be an opportunity to apply for a COA at the end of your pre-application meeting.
If not, please return the completed form with any supporting material to any of our service centres.
What happens next
We can take up to 20 working days to assess your COA application.
We will let you know by email or post if your COA is approved or declined.
You should know
It is an offence to carry out building work for which you need a building consent before you get a building consent.
Any building work we cannot verify as complying with the building code will be listed on the certificate of acceptance as exclusions.
If you can't demonstrate compliance with the building code, we may refuse to issue a COA, and you may also need to remove the building work.
Issuing a COA for unauthorised building work does not limit us from taking further enforcement action.
