This link is to a video story (high speed needed?)(sorry about the commercial) http://us.video.aol.com/video.index.adp?mode=2&guideContext=65.491&pmmsid=1673955
680.41 Emergency Switch for Spas and Hot Tubs.
A clearly labeled emergency shutoff or control switch for the purpose of stopping the motor(s) that provide power to the recirculation system and jet system shall be installed at a point readily accessible to the users and not less than 1.5 m (5 ft) away, adjacent to, and within sight of the spa or hot tub. This requirement shall not apply to single-family dwellings.
Makes one think the last sentence should be deleted.
On a slightly different topic, how would you rule on a townhome where the hot tub is in the unit owner's "back yard"? I have assumed in the past that the intent in single-family dwellings was that it wasn't public or semi-public access as would be for an apartment complex or hotel or health club. I guess by the letter of the code I may have been wrong.
