THINGS TO CONSIDER
Do you require a building consent for your work?
Will the work require a resource consent?
Have you engaged a builder who is a LBP with the appropriate licence?
Remember that the building process requires the appropriate inspections to be carried out during the construction process and that if there should be a failure in this process, the issue of a Code Compliance Certificate may not be simple. Additional work may be required to satisfy council that the work has been done properly.
Try to understand your legal obligations as they are defined in your Building Contract. This helps to minimise misunderstandings during the building process.
