Also called: Margin, Open space around the building
The open space that must be left between a building and the plot's boundaries, on the front, sides and rear, as set by the local building bye-laws.
How it works and what to check
Setbacks depend on the plot size, road width, building height and city. They keep light, air and access for fire engines. A plan is sanctioned only if it leaves the required setbacks.
Covering the setback with an extension, shop or extra room is a common violation in independent houses and builder floors. It can lead to a demolition notice and trouble with a loan or sale.
Common questions
Can I build in the setback area?
Generally not, beyond the small projections the bye-laws allow. Building there violates the sanctioned plan.
Where do I find the required setbacks?
In the city's building bye-laws, and on your sanctioned plan.
