I requested a copy of my building plans from the city and I received them but I want to make sure I am reading them right. It looks like the foundation says the following:
It looks to me like it says 30 inches square by 18 inches deep and the rest pertains to the rebar?
Also, in the copy of the plans below you will see that the garage foundation (in orange) is different from the living room (in pink). I have a pink square representing a 3rd car garage the way my house was built. Does that use the pink foundation plan or the orange one?

Those notations (I see 3 on the plan...you’ve circled 2 of them) are in reference to specific footings close to the notations.
Yes, it is calling out the size of the footing, depth of the footing and the reinforcing steel and it’s location in the footing. It says, 30” square by 18” deep concrete pad with 3 - #4 bars each way in the bottom of the footing.
BTW, the rebar should not actually be on the bottom, but held 3” above the ground.
Each concrete pad is shown in the plan and the corresponding size and rebar is shown. So, you’ll use the notation circled in orange for the garage and the one circled in pink for the living room...and I don’t see any square pad in the “pink rectangle”.
