Are You Building a Home?

Before you build your home, it is important to familiarize yourself with construction-related laws in the Cook Islands. The following is not intended to provide legal, construction, design, or planning advice. It is the duty of anyone responsible for building work to understand and meet their obligations.

You will be able to purchase below, the Cook Islands Building Code 2019 – this provides guidance on the Building Regulatory system in the Cook Islands and how it works. This can help ensure that your development is compliant.

There will be changes to the building legislation and guidance however, check whether you are reading the most up-to-date version. As the homeowner, you can partner with others in this process, but ultimately it is on you to make sure your ducks are in a row.

Apply for a Building Permit

In order to construct any structure in the Cook Islands, you must apply for a Building Permit. Be clear with your building team who will be responsible for filing a building permit, such as a contractor or builder, with a full understanding of when each permit needs to be obtained. It’s important that any building development complies with the relevant Cook Islands Building Codes and Regulatory to certify that the final building is safe and fit for purpose. There are three agencies involved in the granting of a Building Permit.

These are;
1) National Environment Service (NES)
NES ensure that there is minimal to no significant environmental impact of any new building or development. Collect an Environmental Significance Declaration form from NES.

Submit the completed form with four copies of the building and site plans and wastewater design report.

The information on these documents will be used to determine whether or not an Environmental Impact Assessment (EIA) Report is required. NES is mainly concerned about soil and beach erosion, pollution, waste management, adaptation to climate change and conservation of our natural resources. Once the declaration has been reviewed, and if no environmental concerns have been identified, a permit will be issued. Click here for NES Website information and contact details.

2) Ministry of Health

Ministry of Health review and approve the design and installation of the sanitation and sewerage systems for new developments or buildings in Rarotonga and Aitutaki.

There are different types of sanitation and sewerage systems to choose from. All you do is submit an application to the Ministry of Health to review and approve the sanitation and sewage system design. This is to ensure it is in compliance with the health, environment and building regulations.

3) Infrastructure Cook Islands (ICI)
Once approval of the sanitation and sewage system design for the building or development has been received from Ministry of Health, the next stage is to submit a final application to Infrastructure Cook Islands for final approval that the design complies with the Building Regulations and Cook Islands Building Code. Infrastructure Cook Islands administer the application of the Building Acts and Regulatory and the associated Cook Islands Building Code. This includes minimum dimensional requirements and site layouts, structural integrity and safety, electrical installation and safety and mechanical ventilation requirements, among other key design aspects.

Regulatory Review Requirement

Once approval has been granted by ICI, a Building Permit will be issued, allowing you to commence with the construction phase of the new building or development. Regulatory reviews may be required by all three agencies. Throughout construction, ongoing inspections of the site works may be required. Permits should be accounted for in your budget, and can also affect your timeline. Some people don’t see the point in obtaining all of these permits, but this process is only carried out to ensure the safety of all that will access the structure or development.

Frequent communication with everyone involved in your build project, combined with your understanding of the process, will ensure the proper steps are being taken.

If you’re doing it yourself, be informed, educated, and compliant from the start, or else your project could end up having to be altered or even completely removed later on. Do your research and build smart.
