does anyone know of specific requirements for receptacle locations in warehouses and office space? it seems the code book only actually applies to dwelling units. Help.

That's correct. In non-dwellings, there's no set rules other than 210.60, 62 and 63.

480,
I concur.

As I understand it, a commercial electrical designer will calculate all required loads and supply them. The calculated load will be supplied (plus a little margin if it can be justified).

In a residence, the load is estimated on probable usage within a square-footage calculation, incorporating the 'Diversity' rule.

I was called to task on these three times in the last three years by Master electricians, and my NEC references were always the last word. Just as your NEC references will be the last word on this matter!

I haven't designed a warehouse yet. But for offices, I like to put a double-duplex at the desk (computer location) and another duplex somewhere else in the room. In the hallways of office buildings, I like to put receptacles no further than 50 feet apart (based on a vacuum cleaner or buffer having a 25 foot cord). These are just my own design preferences. There are, as has already been said, no code requirements.

Welcome to the forum.
 
I would say 210.50(B) would require a receptacle if there is a cord and plug load to be served, this is what deferents between load requirements of a dwelling and non-dwelling, dwelling requirements are for having a receptacle for convenience to stop people from using extension cords and in non-dwellings are placed only if there is a corded load to be served, this is why the 180 va rule only applies to non-dwelling.
 
Welcome to the foru. You are right about the code speeling out placement only in residential. 480's response is correct in the code references. A lot of the work I am currently doing spells out the placement in the RFP.
