Retaining wall questions
Plain answers to what people ask about a retaining wall before they build: council approval, boundary setbacks, overlays and the site plan. Each answer ends with how to read the rules for your own lot.
A fence on a retaining wall adds height and load the wall has to carry. What decides whether it needs approval, who decides, and what the site plan shows.
How high can a retaining wall be without approval?The height where a retaining wall needs approval falls once the wall holds something up or sits near a boundary. What decides it, and what the plan shows.
Can I build a retaining wall on the boundary?A retaining wall can often sit on or near the boundary, but its height, footings, drainage and the neighbour’s land decide how. Who to ask, and what to show.
