garage under living space

I am planning on building a garage under some living space within the section of an existing basement. I know there are fire wall requirements and that the garage floor needs to slope away from the house. That's all spelled out in the IRC. However I was also under the impression that a curb was required to prevent fuel spills from entering the remaining basement space. Yet I cannot find any reference to that within the IRC. Is there any such requirement? Where can I find it?
Many thanks.

Check with your local permit/inspection office. They should be able to inform you what they require and/or enforce.

All the new houses I've painted with garage in the basement either had a complete level slab with an unfinished basement or a 4" [approx] lower garage area when the basement is finished. I don't know what the specs are for converting an already existing space.

Codes and enforcement can vary greatly in different locales - that is why it is best to contact your local zoning dept, after all they [including inspector] have the final say.

Rule of thumb is a four inch curb or below top of foundation when a garage is attached or inside a living space. Weather the code calls for one or not it is a good idea to keep flammable solvents from soaking into the wood wall bottom plates.
