Floor slope
Floor slope
(OP)
I am looking for a provision in a building code (IBC) that would indicate the minimum slope required for a garage floor. Does such a provision exist?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Agrees with what JAE said.

Anything flatter than that is liable to disappear if you have expansive clay underlying the slab.

A 0.5% slope also as JAE noted, is pretty much the bare minimum (for pavements). A 1/8" per foot is about 1% and will cause positive drainage; although not adequate for critical drainage such as a roof.
It doesn't appear that you have a section to reference, just a general consensus that it should be in that 0.5 to 1 percent range at least.

Your maths sounds off, because if you didn't grade the fill and just used extra concrete, you would get (20'x20'x (5/12)'/2 )*.333^3(6mx6mx.125m/2)= 3 cubyard (or 2.25cubm)which is about $2000 Max, probably more like $800 on a good day given.
Someone please check my maths this whole feet to yard to inches thing has me in a spin.

The code has no direction on how far apart the floors should be either. Some decisions are left up to the designer.
