Overview

## Why build a granny flat in SEQ?

Granny flats are one of the most versatile property investments available to Queensland homeowners. The right secondary dwelling on a well-located Brisbane or Gold Coast block can generate meaningful rental income, increase your property’s overall value, and provide flexible housing options for your family over time.

With Brisbane’s rental vacancy rates among the tightest in Australia and rental yields on Gold Coast properties remaining strong, a compliant secondary dwelling is a compelling investment in the current market.
