GFI protection, no lighting on the same circuit, that's about it for me. A lot of jobs have a note within the spec that the EC is responsible for temp power, receptacles w/GFI at defined distances, lighting , etc. I do check GFIs.
As to 'patched' when I see them, I say something. As to homemade...I don't feel that it's my axe to grind. Unsafe items get my attention also, usually with a verbal to the offender. Usually I hear...'that's not my cord'. Most ECs keep an eye open, especially when they have scheduled inspections.
On the OSHA side, I know of one jobsite that raised a few $$$ for cords.
