Planning to add a Granny Flat?

If you’re considering a granny flat - whether for extra rental income, multigenerational living or boosting property value - you’ll need a BASIX Certificate before lodging your Development Application. At Green Certify, we make the process simple and fast, offering assessments tailored specifically for smaller residential dwellings like granny flats.

Our certified assessors ensure your project meets NSW sustainability standards, addressing energy efficiency, water usage and thermal performance, while keeping your design and budget in focus.

Why a BASIX/NatHERS Certificate is Required?

All new residential developments in NSW & QLD, including granny flats and studio dwellings, must comply with BASIX/NatHERS requirements. These certificates verify that your design meets energy and water conservation standards, helping reduce ongoing utility costs and environmental impact.

Whether your granny flat is attached, detached or part of a dual occupancy plan, we provide fast, accurate compliance support to ensure your project meets all regulations.
