Chhajja · छज्जा
Building regulation
In one line
A projecting weather shade over a window or door.
A chhajja is the cantilevered ledge above an opening that keeps sun and rain off it. Regulations cap how far it may project and whether that projection may enter a setback — which is exactly where people get caught, because a chhajja is usually added after the walls are up.
