Inspections
During the building consent process, we will identify the inspections required to ensure your project meets Building Code compliance. These inspections, along with any specific documentation needed for each one, will be listed on your issued Form 5 (Building Consent). The form 5 will also contain other information like advice notes and conditions.
The granting of a building consent is conditional on enabling the building work to be inspected. At various stages during construction, you will need to arrange inspections to verify that the building work has been completed in accordance with building consent requirements. The number of inspections required will depend on the complexity of the building and the systems within it.
Under section 90 of the Building Act 2004, agents authorised by the Council (acting as a building consent authority) are entitled, at all times during normal working hours or while building work is being done, to inspect:
- land on which building work is being or is proposed to be carried out; and
- building work that has been or is being carried out on or off that building site; and
- any building.
Sometimes it is necessary for specialists to do inspections in addition to those carried out by the Council. If there has been an agreement for third party construction monitoring (e.g. by your engineer), these inspections will be listed in the building consent construction documentation and advice notes provided to you.
If it is determined that a resource consent is needed to undertake the activity, a certificate is issued under Section 37 of the Building Act. This certificate prohibits work commencing until resource consent issues have been resolved, even if your building consent has been issued. A building inspection will not be able to be booked until the Section 37 has been lifted.
Self-certified plumbing and drainlaying
If your building consent lists plumbing or drainlaying as self-certifiable, the Council does not inspect that work — an endorsed plumber or drainlayer certifies it and provides a certificate of compliance. All other building work is inspected as usual. See our section self-certification plumbing and drainlaying at https://www.greydc.govt.nz/06your-home/building-co...
Booking Inspections
Grey District Council has policies and procedures in place to plan, carry out, and manage building inspections in accordance with Regulation 7A of the Building (Accreditation of Building Consent Authorities) Regulations Council is required to complete at least 80% of building inspections within three working days of the date the inspection is requested by the building owner or their authorised agent, as required by Regulation 7A of the Building (Accreditation of Building Consent Authorities) Regulations 2006. 3 Working Day Timeframe for Inspections Guidance
Providing as much advance notice as possible of your preferred inspection date helps us to schedule inspections efficiently and increases the likelihood that your inspection can be completed on the day requested.
To arrange an inspection, please call us on 03 769 8625 or email building@greydc.govt.nz Please have your project details ready when booking an inspection.
When you contact us, it’s helpful to have key information on hand—such as your building consent number, site address, the type of inspection you're requesting, and the name of the licensed building practitioner (if applicable). This helps us quickly locate your consent, confirm the inspection requirements, and schedule your booking efficiently.
For Restricted Building Work (RBW) you must notify us of the Licensed Building Practitioner(s) (LBPs) who will be doing the work before you can book the first inspection. (If you filled them in on the building consent application form in the first instance and they have not changed, you are able to book inspections.)
It is important the inspector can gain safe access to the site and / or building to inspect the building work.
Self-certification for plumbing and drainlaying
You can choose to have eligible plumbing and drainlaying certified by an endorsed plumber or drainlayer instead of inspected by the Council. If you want to use this, identify the plumbing and/or drainlaying to be self-certified in your application (Form 2) and on your plans, and use a practitioner who holds a current self-certification endorsement. See https://www.greydc.govt.nz/06your-home/building-co... for full details.
On-site requirements
Who and what documentation must be onsite
It is preferred that you or a representative is on-site for an inspection.
You must be on-site when we are attending a final inspection, and all the approved building consent documentation must be onsite and available (this may include hard copy or electronically readable) during all inspections.
Access to above-ground areas
The area to be inspected may also include those that cannot be easily accessed. An example may be the second or third storey of a building or another area that cannot be easily seen from ground level.
You will need to provide the building inspector with a safe and suitable method (for example, scaffolding) for accessing the above-ground areas so that the inspection can take place.
Our officers may refuse to carry out an inspection if health and safety risks are not being adequately managed on site.
Remote Inspections — A Modern Option
Remote inspections are available for low-risk building work, arranged with our building team. This can reduce wait times and give more flexibility around booking an inspection.
How to Book and Use a Remote Inspection
Step 1: Check Eligibility
Remote inspections are suitable for low-risk or straightforward building work. More complex or high-risk projects may still require an in-person visit.
Phone 03 769 8625 and speak to our building team to confirm if your project qualifies for a remote inspection.
Step 2: Schedule Your Inspection
Remote inspections are booked in the same way as any other inspection: phone us on 03 769 8625 or email building@greydc.govt.nz. When you book, let us know you would like a remote inspection. We will confirm whether your inspection is suitable to be done remotely, and that you have a smartphone with a camera and good mobile coverage on site. At the agreed time, the Building Control Officer will send a video call link to your phone.
Step 3: Prepare for the Inspection
You will need:
- A smartphone with a working camera
- Location services turned on — this confirms you are at the consented site
- A stable internet connection and a charged phone
- Clear access and good lighting in the areas being inspected
No app download is required. Please also check that the mobile number on your Objective Build record is correct, as your invitation is sent to it by text message.
Step 4: Join the Remote Inspection
Shortly before your inspection time, you will receive a text message with a link to join a video call. Select the link and allow camera and microphone access when prompted.
During the call, the inspector will guide you around the site and ask you to show specific areas or aspects of the work, in the same way as an in-person inspection.
Step 5: Inspection Outcome
The inspector records the outcome during the call. This is saved directly to your building consent file for compliance and future reference.
NOTE: Guidance on remote inspections can be found here https://helpdocs.objective.com/build_applicants/Content/Remote%20inspections.htm
What happens during an inspection
During each inspection, the Building Control Officer will verify that the building work completed to date has been carried out in accordance with the approved building consent documentation, including the consented plans and specifications, and that it meets the requirements of the New Zealand Building Code.
You should ensure that the approved consent documentation is available on-site and that someone with knowledge of the building work is present to answer any questions the inspector may have.
Inspection Results
After each inspection, the Building Control Officer will complete an inspection report detailing the outcome. Relevant parties will receive a notification once the report has been generated and is available to view through the Objective Build Consent Portal.
The inspection report will outline any areas of the building work that are incomplete or do not comply with the approved consent or Building Code. If issues are identified, the report will state whether work can continue (possibly under specific conditions), must stop, or if a Notice to Fix may be issued.
In cases where work is not approved, further inspections will likely be required. This will be noted in the report. You or your builder will need to address any non-compliant or incomplete work before re-inspection. For more serious issues, a Notice to Fix may be issued, detailing what needs to be corrected and by when.
A Notice to Fix (NTF) is a formal document issued by the Building Consent Authority (BCA) or Territorial Authority (TA) advising that a breach of the Building Act has occurred and must be remedied. The NTF will specify what work must be corrected and the timeframe within which this must be done. Failure to comply with a Notice to Fix may result in further enforcement action being taken. If you receive a Notice to Fix, we encourage you to contact us as soon as possible to discuss the steps required to achieve compliance.

Inspection Types
Please note the following inspections are specific to Grey District Council:
Preconstruction meeting / Inspection
A pre-construction meeting/inspection is an opportunity to ensure everyone involved in your building project is on the same page before work begins. These meetings are especially useful for complex or staged projects, such as commercial builds.
During the meeting, council staff will:
- Review your building consent and confirm required inspections.
- Clarify any consent conditions, including erosion and sediment control requirements if applicable.
- Discuss construction sequencing, access needs, and site safety requirements can be addressed.
- Confirm contact details for key parties, including licensed building practitioners (LBPs).

Final
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.
The final inspection 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. 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 for the contract 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.

- Specified systems: operational and documented.
- Producer statements and certificates: electrical, gas, fire safety.
- Compliance schedule: confirmed or amended as needed.
Construction Monitoring
Sometimes it is necessary for specialist to conduct inspections or construction monitoring in addition to the inspections carried out by Council. If a specialist inspection is necessary the Building Consent (Form 5) will nominate what monitoring is required and who should undertake the monitoring. Typically these types of inspections involve having a geotechnical engineer confirm ground stability or having an aspect of specific structural design checked by a registered engineer.
Each building site is unique and will have its own individual requirements so it's important you read the documents and pay particular attention to any conditions listed on the issued building consent document. All consent documentation should be kept on site at all times. To help identify your particular site, please ensure adequate signage is in place, especially in remote or rural locations.
