Does a slab house need a footer?

Yes, a slab house typically requires a footer, also known as a footing. The footer serves as a stable base that helps distribute the weight of the structure and provides support, preventing settling or shifting over time. It is usually poured below the frost line to protect against ground movement due to freezing and thawing. Properly designed footers are essential for ensuring the long-term stability and durability of the slab foundation.
