Assume for a second that my jurisdiction has adopted 2011 NEC code as legally binding without significant amendment. This code requires (406.11) that 120V 15/20A outlets in all areas defined in NEC 210.52 must be tamper-resistant, and that existing grandfathered outlets are only grandfathered until replaced; any replacement must be TR. Exceptions are:
- Outlets more than 5.5' off the ground (only common one I can think of is the one for a garage door opener)
- Outlets designed to be used by a major appliance which normally blocks access to the receptacle (mostly in the kitchen; fridge/stove/oven/dishwasher)
- Outlets built in to light fixtures or lumieres (and so replacing them would involve replacing the entire light fixture which may be expensive or impossible)
210.52 covers pretty much any outlet in an interior space of a residential building, including attached garages. It doesn't specifically cover closets but the NEC doesn't treat closets any differently than the interior space containing the closet. It also doesn't (AFAIK) cover attic spaces that haven't been finished. I don't have a basement so don't worry about that.
All that being said, is there any outlet in my house, besides the one for the fridge (ex 2), stove (ditto) and garage door opener (ex 1 - on the ceiling), that wouldn't be required to be TR if/when I replace it?
This also begs the (somewhat argumentative) question of why standard (non-TR) outlets are still sold to "amateur" electricians. At least in my area, they are only code-compliant in commercial spaces that aren't healthcare, child care or hotel spaces (ask the next 100 people who buy an outlet where they plan to install it, and 99 will say "in my home"), and in VERY LIMITED circumstances in residential, where a TR outlet would also be just fine. I'm not sure exactly how the store would be expected to tell who would install it in a compliant way, but it seems disingenuous for a store to sell 10-packs of outlets that would be illegal to install without at least having the POS system throw up a flag at checkout (like they already do for age-restricted items like glues/paints/solvents).
