During construction of your building project, you'll need to arrange inspections to ensure that the work is done in accordance with the approved plans.
The list of inspections you need will be provided as part of your building consent documentation.
The final inspection is for the "Code Compliance Certificate", the official document which verifies that the building work complies with the consent. It's an important document, especially when it comes to selling your property.
If building work has been done in the past without achieving a Code Compliance Certificate, it may still be eligible for a "Certficate of Acceptance", which provides some verification that work meets the standards of the Building Code, at least as the Building Code was written at the time of construction.
