The BASIX standards still apply if you have access to your own off-grid water, electricity or gas supply.

If the proposed building does not have mains water supply, it is expected to have sufficient alternative water sources (such as rainwater tanks) connected to satisfy demand. BASIX assesses if these water sources will satisfy the demand without needing excessive top-up of water from off-site. Depending on the location of the building, the BASIX score in the water section needs to achieve a required standard (e.g. 40 in coastal NSW).

If the proposed building is not connected to the electricity grid, other alternative energy sources (such as bottled gas) are required to satisfy domestic demand.
