Getting a building consent can feel daunting, but the inspection process follows a logical sequence designed to make sure your project is safe and meets the NZ Building Code. Once you understand the steps, it becomes much easier to plan your build and avoid costly delays.
Step 1: Lodge Your Building Consent Application
Before any work starts, you (or your builder) must apply for a building consent through your local council or a Building Consent Authority (BCA). Your application needs to include plans, specifications, and producer statements where required. The BCA has 20 working days to grant or refuse consent once they have everything they need — though they can put the clock on hold if they need more information.
Not all work requires consent. Some minor work falls under Schedule 1 exemptions under the Building Act 2004. However, exemptions can be tricky to interpret, so always confirm with your council before assuming your project is exempt. You can find guidance on what requires consent at MBIE Building Performance.
Step 2: Understand Your Inspection Requirements
Once your consent is granted, the BCA will issue a consent document that lists the mandatory inspection stages for your project. These vary depending on the type and complexity of the work. Common inspection stages include:
- Pre-pour foundation inspection — before concrete is poured
- Framing inspection — once the structural frame is complete but before lining
- Pre-line inspection — checking insulation, bracing, plumbing rough-in, and electrical rough-in before walls are lined
- Drainage inspection — for any new or altered drainage
- Weathertightness inspection — checking cladding, flashings, and junctions (relevant to NZ Building Code clause E2)
- Final inspection — when all work is complete
Read your consent document carefully and keep it on site at all times — inspectors will want to see it.
Step 3: Book Each Inspection at the Right Time
You must book each inspection before covering up the work. This is critical. If a building inspector arrives and finds that framing has already been lined, they may require you to open up the walls — an expensive mistake. Most councils allow you to book inspections online, by phone, or through a portal.
Allow enough lead time. Some councils are busy and may need several days' notice. Talk to your builder about scheduling inspections into the build programme from the start.
Step 4: The Inspection Itself
A building inspector from the BCA will visit the site and check the work against your approved plans and the NZ Building Code. They may:
- Measure structural elements and check they match consented drawings
- Check bracing and fixings against NZS 3604 (the timber-framed buildings standard)
- Inspect weathertightness details for compliance with E2
- Review plumbing and drainage against G12 and G13
- Ask for producer statements or manufacturer documentation for specific products
If everything is satisfactory, the inspector signs off that stage. If not, they issue a notice to fix or request remedial work before re-inspection.
What Happens If Work Fails an Inspection?
Don't panic — it happens. The inspector will document what needs to be corrected. Once the remedial work is done, you book a re-inspection. Your Licensed Building Practitioner (LBP) should be able to advise on the fastest path to compliance.
Step 5: Restricted Building Work and LBP Sign-Off
Restricted Building Work (RBW) — such as structural work, weathertightness, and foundations — must be carried out or supervised by a Licensed Building Practitioner. At the end of the project, your LBP must provide a Record of Work confirming they completed or supervised the RBW. This is a legal requirement and must be submitted before your Code Compliance Certificate can be issued.
Step 6: Final Inspection
Once all work is complete, you book a final inspection. The inspector checks that everything matches the consented plans and that all previous inspection stages have been signed off. You'll also need to provide:
- All required producer statements (PS3/PS4 from engineers or specialists)
- LBP Records of Work
- Manufacturer documentation for any specified products
- Any other documentation listed in your consent
Step 7: Apply for Your Code Compliance Certificate
After a successful final inspection, you apply for a Code Compliance Certificate (CCC). The BCA has 20 working days to issue it. The CCC is your legal confirmation that the building work complies with the Building Code. Without it, you may have difficulty selling your property or making insurance claims related to the work.
If you don't apply for a CCC, the council can still issue one on their own initiative — but it's far better to apply promptly.
When to Call a Professional
Building consent and inspections involve legal obligations that are easy to get wrong. A qualified builder — particularly one who holds an LBP licence — will manage the inspection schedule, liaise with the BCA, and ensure the paperwork is in order. For plumbing and drainage inspections, only a tradesperson registered with the Plumbers, Gasfitters and Drainlayers Board can carry out restricted work. For electrical rough-in inspections, work must be done by a registered electrician under the Electrical Workers Registration Board.
