Setting out checked against the plot boundary and setback
Why — act while you have leverage
A house set out wrong is a house in the wrong place. In Kerala the setback is a permit condition, and discovering a shortfall after the plinth (the base the walls start from) is up is a demolition conversation, not a correction.
What to look at
- Each setback measured to the actual survey boundary
- Both diagonals equal within tolerance
- The permit drawing on site, not a memory of it
How to check it yourself
Before excavation, the setting-out lines are checked against the approved permit drawing and the plot boundary — all four setbacks measured from the boundary itself, not from a neighbouring wall or fence. Diagonals of the layout are measured to confirm the rectangle is square.
Where this comes from: Kerala Municipality Building Rules (KMBR) 1999 — coverage and setback provisions; NBC 2016 Part 3 (required by law)
