I did a search in 2008 NEC for the word "laundry" and the following articles are all I found containing that word that would apply to a single family dwelling.
210.11(C)(2)
Laundry Branch Circuits. In addition to the number of branch circuits required by other parts of this section, at least one additional 20-ampere branch circuit shall be provided to supply the laundry receptacle outlet(s) required by 210.52(F). This circuit shall have no other outlets.
210.50(C)
Appliance Receptacle Outlets. Appliance receptacle outlets installed in a dwelling unit for specific appliances, such as laundry equipment, shall be installed within 1.8 m (6 ft) of the intended location of the appliance.
This is not really part of the discussion of OP for the most part, but may need some consideration in the discussion.
210.52(F)
Laundry Areas. In dwelling units, at least one receptacle outlet shall be installed for the laundry.
there are exceptions to this but do not apply to single family dwellings
As of the 2008 code I don't see where it says what outlets are for the laundry, it just says you need at least one and it shall be supplied by a 20 amp branch circuit. I know some time in the past it was worded that the laundry circuit was allowed to supply other outlets in the laundry area but that wording apparently has been removed at some time. As it reads now it is up to the installer and AHJ to determine what is a laundry outlet, and what outlets are allowed to be supplied by the required laundry circuit.
There were hits in 220.52(B), 220.82, 220.83, 220.84 but these are all about feeder and service calculations and not about the topic of the OP.
There are also hits in 550, 551, and 552 but are not about the topic of the OP, although most are similar requirements of 210 and 220 requirements.
Plus there were hits in annex D and in the index - again not about the topic of OP.
