So lets say hypothetically I have a room that measures 15 feet by 12 feet with no doors or windows or anything other than wall. I start at the corner of a 15 foot wall. I measure 6 feet and mark a spot for an outlet. I then measure 12 feet which would put me 3 feet into my second wall (6 + 12 -15) and mark the 2nd outlet. I then measure 12 more feet which would put me 3 feet into my 3rd wall (3 + 12 -12) and mark the location of my 3rd outlet. I then measure 12 more feet which would put me right at the corner of my 3rd and 4th wall (3 + 12 - 15) and mark the spot for a 4th outlet. I would then need one more outlet 12 more feet away at the corner of my 1st and 4th walls to meet the requirement of having no spot more than 6 feet from any wall. Am I adding this correctly?
Since there is no door to use as a starting point, you pick a spot and mount your first receptacle. Then you measure 12 feet (or less) from there to your next receptacle, then 12 feet (or less) again, etc etc, until you get back to the first receptacle.

So I just want to make sure that the 1 1/2 foot section at each end can, by code, be serviced by a receptacle on an adjoining wall if it is within 6 feet (in other words within 4 1/2 feet of the shared corner between the two walls).
That is correct. The wall measurement continues around the corner.
The 3 foot wall in the example does not require a receptacle if there is one on the adjoining wall that is within 6 feet because the wall continues around the corner. If there was a door on either side of the 3 foot wall then it needs a receptacle. You don't want cords going across doorways if someone put a lamp or TV etc on that wall

I agree but you guys do a poor job of explaining why it is requried.

It is because the code requires a recep in any wall space to be no more than 12 feet from another recep in that wall space.

As you stated later, it is a 2 foot wall.

So, in a room with a closet and a door, there will be 2 wall (spaces (presuming at least 2 feet of wall between each door)). Each of them is treated as an individual wall (space). In a room with 5 closets with at least 2' walls between each closet, (and a door of course (with no less than 2 feet between it and any closet door)) there would be 5 wall spaces.

but regardless, in the OP's example of the 12'X3' room, there still does not have to be a recep on the 3' wall , unless the a layout specifically places one there. It would be possible to place receps in that room with none being placed on either 3' wall.

Nap,

I'm confused. Do you agree that the measurements continue around corners?

I don't understand why a 3' wall wouldn't require a receptacle, given the code language.

It would require a receptacle if any point on the wall is farther than 6 feet from the nearest receptacle.

It sounded like Nap was defining a wall space as being one separate wall. That's how I always understood it, but now I am confused. For example, a wall that is 15' wide is one wall space, and an adjoining wall would be considered a separate space, requiring the measurement to begin again.

It sounds to me like a wall space would begin and terminate at a door (or anything else that you wouldn't usually pass a cord across).

well, I guess that's the obviously rational answer. Sometimes I try to read too much into a sentence.

a wall space is not a separate wall. It is an independent and continuous wall (at the floor line). You start measuring at a door opening (or other interruption as stated in the code) and run until you come to another door opening et al. That is a wall space. Then, beginning on the other side of the door opening, you begin a new wall space and so on until you circumnavigate the room.

yes, measurements continue around a corner.

if it was an independent wall space, it would. If it was merely 3' within a larger wall space, it may or may not depending on how things were laid out. Any wall less than 12' could be without a receptacle as long as the receps on either side of that wall section were no more than 12' apart from each other. If a wall was over 12' long, it would be impossible to not place a recep on that wall as it would be impossible to have 2 receps on adjacent walls that were no more than 12' from each other as measured across that wall.

Simply measure 12' from receptacle to receptacle along an unbroken wall, so that at any point along the wall would be accessible to a 6' cord, and the presence of a corner doesn't end that wall space.

Absolutely. I sometimes put in more than is required by those maximums.
