If you are building a new home in Sydney, you need to know about the BASIX Certificate. This is important information for all development applicants.

The NSW Government is committed to conserving our scarce water resources and reducing the impact of greenhouse gasses on our climate.

BASIX (the Building Sustainability Index) was introduced to local government areas in the Sydney metropolitan area on 1 July 2004 to make sure new homes use less water and energy.

On 1 July 2005, BASIX was extended to apply across New South Wales. This means, you need to include a BASIX Certificate with your proposal to build a new house or dual occupancy anywhere in NSW.

BASIX for multi-unit residential developments has been required from 1 October 2005.
