An open timber pergola under 20 square metres, under 3.6 metres high, and set back from the street doesn't need a permit at all. But the moment a roof goes on, even a clear polycarbonate one, it's legally reclassified as a verandah, and that makes a full building permit mandatory. Build it without one, and you're looking at council demolition notices, an insurance claim that gets refused after a storm, or a legal headache when you go to sell. Jake talks you through this distinction before anything gets built, tells you straight whether your plans need a permit, and manages that process properly if they do.
