I'm familiar with Part 15 FCC testing for intentional radiators (3 meter limits of certain power, must be filed with FCC, requires accredited lab), but I'm a little unclear on the Class B unintentional radiators?
I know from another product we received a Declaration of Conformity for the Class B limits, and that nothing was filed with the FCC. As the "responsible" party we make the certification the product conforms to Part 15 Class B.
Are we required to use an accredited lab for the Class B unintentional measurements? We have a LISN and 30MHz to 1000MHz EMI antenna in house. Ultimately, my company's you know what, is on the line as the certifying party. So why can't we take the readings, and certify?
The only place I read that the Class B DoCs must come from accredited labs, are from the websites of accredited labs!

It depends on what it is, look at what your device is in the table:

If the product being tested only needs verification, then you could test at a lab that has been registered with the FCC. If you need a DOC, then you'll need to go to an accredited lab.
Of course, you can always test in your lab before you send the product out for testing to make sure the testing goes smoothly and you don't have to do a second round.
No, the FCC also tells you that you need DOC's from an accredited lab:
