Inspections during construction are important - they ensure compliance with development consent conditions and Complying Development Certificates, and also ensure building work meets proper standards of health, safety and amenity.
Your Principal Certifying Authority will conduct all your inspections, including your mandatory critical inspections, which are required for all classes of buildings, including houses, garages, carports and pergolas. Your Principal Certifying Authority will give you a list of these inspections and any others that will be needed. These inspections are carried out at various stages during construction. If Council is your Principal Certifying Authority you will be notified in writing of the mandatory critical stage inspections and any other inspections required. If you have a private certifier as your Principal Certifying Authority then they will inform you of the inspections needed.
Clause 162A of the NSW Environmental Planning and Assessment Regulation 2000 sets out mandatory critical stage inspections. If these inspections are not carried out the Principal Certifying Authority will not be able to issue an Occupation Certificate. The actual inspections required by the legislation are dependent upon the type of building being constructed, and what class of building it falls into.
Here is a general guide:
It is your responsibility to give your principal contractor (builder) the list of the inspections that are required by your Principal Certifying Authority, and as your construction reaches different inspection stages either you, or your principal contractor, will need to contact the Principal Certifying Authority. Depending on the type of building being constructed and how it is being constructed your Principal Certifying Authority may be able to carry out two or more of the required inspections at the same time. If Council is your Principal Certifying Authority you will need to:
Should the inspection be found to be defective, you will be required to fix the fault and arrange for a re-inspection of works prior to proceeding to the next stage of construction.
When the whole of the work is completed, a final inspection needs to be carried out to the satisfaction of your Principal Certifying Authority, and an Occupation Certificate issued by the Principal Certifying Authority verifying that the work is completed in accordance with your development consent and is fit for occupation.
