ECN Forum Forums Code Related Discussion NEC & other Code issues to GFIor not to is the question

i always install GFI outlets for construction trades in the houses i wire.
but at the house across the street(snooping on my competition)they use regular outlets is this legal or should they be gfi?
i have heard that when permanant power is hooked up you dont need to be GFI protected but dont know if this is a wives tale.

thanks,
