Hazee has it right, section 210 it is. The requirement for a laundry room GFCI within 6' of a laundry sink is a new addition to the 2005 NEC. Prior to 2005 laundry rooms were not required to be GFCI protected. GFCI protected kitchen countertop receptacles has been required for a long time. Bare in mind that the NEC is really the minimum, and local codes rule over these. Per the curent NEC, any time a receptacle is replaced in an area that a GFCI wasn't required in past code but is required per new code, the receptacle must be replaced with a GFCI type. Here's a couple of links that'll give you lots of details. The first one details laundry rooms and the second one details everything else.
