• A final inspection is carried out when all other listed inspections have been completed and passed, and all detail on approved consent documentation has been completed.
• Sometimes, other than the final inspection, there will be inspections (including effluent field, heating unit and solar hot water system) which need to also be completed. Please ensure that these inspections are also booked in so additional time has been allocated. This assists us in distributing all of the inspection bookings.
• This is the last opportunity the Council has to inspect the completed building and it is therefore important that all aspects of the building are complete. In order for the Council to carry out this inspection, the building must be completed to a standard where it has a good chance of passing. It is not designed to provide a list of items for the contractor to complete.
• Some of the following items are commonly identified as failed items at final inspection. These items should be checked by the contractor prior to inspection.

• Check that members of the public can use the premises safely
• Considered as a final type inspection

• Confirmation on whether or not the contraventions recorded in the Notice to Fix (Form 13) have been rectified
• If specified, building work must cease until the Notice to Fix has been lifted

Advisory

• An inspection that is conducted to ascertain the current status of work carried out under a building consent - it is used to provide the customer with guidance on further steps to be taken with respect to the completion of their project.

Other

• An inspection that is typically for a design feature or method of construction that does not fit into any of our standard inspection types e.g. Accessibility inspection

Your building consent will include a Schedule of Specified Inspections which state the range of inspections undertaken during the course of construction. Inspections are project specific and identified/agreed during the processing of your building consent.

Additional inspections may be necessary, depending on the nature of the building work and the manner of construction, or as a result of non-complying or incomplete work.

Each section below contains guidance around what will be looked at during the relevant inspection

Certificate for public use

• Generally for commercial buildings
• The inspector will check that members of the public can use the premises safely

Notice to fix inspection

• Confirmation on whether or not the contraventions recorded in the Notice to Fix (Form 13) have been rectified
• If specified, building work must cease until the Notice to Fix has been lifted
