My understanding is that under the most recent National Electrical Code
(NEC 2008?) AFCI circuit breakers are required for all residential
circuits -- not just in bedroom circuits.

However, I just heard from one unofficial source that AFCI circuit
breakers are not required under the newest NEC for kitchen and bathroom
circuits because they have GFCI protected receptacles. Is that correct?

Not in "wet areas" where GFCI's are required. AND some local areas modify
the national electrical code. For example in Oregon, AFCI's are only
required in bedrooms. And GFCI's are not required for refrigerators/freezers
and sump pumps in garage/basement. These are local modifications to the
national rules.

And some areas do not use the latest national electrical code.

Bottom line: Ask your local electrical inspectors office. Ask about local
amendments and when to get a copy of these. Ask what year of the NEC your
area is going by. NEC adoption map...
