Low Voltage in Stair "Vestibules"

[nsumitha]

Is there any code section that refers to in California to not have any "Foreign Objects" in Stair "Vestibules" specifically.
We do have a project here in Sacramento and there is a confusion that there is no specific code section that talks about having any electrical or low voltage in Stair Vestibules. Could anyone please clarify this confusion. Thanks in Advance.

Well, if you or California can show me how electrical or low voltage is a foreign object, I'm listening.
