Code Compliance Certificate vs Certificate of Acceptance

A Code Compliance Certificate (CCC) is the formal sign-off from the council that completed building work meets the approved building consent and complies with the New Zealand Building Code. It is issued after the council's building inspector conducts a final inspection and is satisfied the work has been done properly.

The CCC is the gold standard of building compliance. It means the work was consented before it started, inspected during construction at key stages, and verified as compliant upon completion. The council carries some liability for the accuracy of its inspections, which provides an additional layer of protection for the property owner.

When reviewing a property's consent history, you want to see a CCC for every building consent. Missing CCCs are a significant due diligence concern.

A Certificate of Acceptance (CoA) is issued by the council when building work was carried out without a building consent, or when the building consent has lapsed. The CoA acknowledges that the work exists and that the council has assessed it to the extent it reasonably can, but it does not confirm full compliance with the Building Code.

The key difference is that the council could not inspect the work during construction. Hidden elements — foundations, framing, insulation, waterproofing membranes — cannot be verified after the fact without destructive investigation. The council therefore accepts no liability for the CoA work, and the risk sits entirely with the property owner.

CoAs are common on older properties where additions or renovations were done without consent, often before homeowners were aware of consent requirements. They are a practical solution for regularising unconsented work, but they carry more risk than a proper CCC.

You do not choose between them — they serve different situations. If you are buying a property, you want to see CCCs for all building work. If some work only has a CoA, that is a yellow flag that requires further investigation. You may want a more thorough building inspection of the CoA work, and your lawyer should advise on the risk implications.

This is not a sequential choice. When reviewing a property's consent history, check whether each building consent has a corresponding CCC. If you find work with only a CoA (or neither), flag this with your lawyer and building inspector immediately. The CoA work should receive extra scrutiny during the building inspection.
