My basement floor is poured concrete over gravel, a vapor barrier and steel mesh. My garage is adjacent to the basement. I assume the garage floor and basement floor are separate pours, since the garage floor is lower by about an inch. The wall separating the garage from the basement is not load bearing.

My question is, assuming the floors were poured correctly, how are the footings placed?

Option 1: Each floor has its own footings around the 4 edges of each floor like this?

Option 2: The two floors share a continuous footing on their long edges, like this:

Or is there another option I haven't thought of?
Thanks for any help!

There is no guarantee of what you might find in any particular house.

The footing is wider than the foundation, the foundation between the house and garage will be under that wall

The footing may not be and is not like directly below the floor often much lower around the garage so it can be at frost level.
The foundation is usually much lower under the main big door.
