Garage conversion: does it need approval
Turning an existing garage into a room people live in: a bedroom, a study, a rumpus room or a self contained flat.
State by state
The position on an ordinary residential lot with no overlay. An overlay on your own lot can change it.
Each row is read from the instrument named against it, on the date shown. Council controls sit on top of all of them.
What the job usually involves
Insulation, lining, a floor, a window for light and ventilation, ceiling height, and somewhere else for the car. The room has to meet the standards for a habitable room and the building changes class, which is why this is the one item on the list with no clean answer anywhere.
What it costs

The overlays on your lot are what decide whether the row above actually applies to you.
