I am designing a floor that will be built directly on top of a garage slab by installing 2x12s nailed to a sill plate fastened to the slab with tap on screws. There will be a bathroom on top of these joists.
do I need a footing at the sill plate where the joists/ bathroom wall are bearing on the garage slab?
is the slab enough to support this load or is a foundation Wall required here? Perhaps just a thickened slab at that point?
Although why do we need anything if the garage slab can support the load of a car?
