I'm wondering how the AHJs in your areas read the code requirements for a Kitchenette in a "mother-in-law suite." This Kitchenette will have a sink, disposer, a microwave and a small dorm-style refrigerator in it. Do the AHJs typically view this as a kitchen requiring two Small Appliance Branch Circuits? Or is this "something else"?

It could meet the definition of a kitchen in Article 100, depending on how someone views the microwave. Does it have an area for food prep?

A small counter top (2' x 2'). It's not urgent. I will just ask the local inspector to see how he sees it. And to put in two circuits is not going to break the bank.

In Wisconsin, the State made the determination quite a few years ago that a microwave is not considered "permanent provisions for cooking".

In my area that's a kitchen, and creates a separate legal unit for rent control purposes, but not for building purposes. Perhaps you can call it a utility sink, and be fine for building code purposes.

If it meets the NEC definition of a kitchen, then it must comply with all NEC requirements for kitchens. It will need minimum of 2 SABC's supplying the counter receptacles. A SABC can serve kitchens, dining rooms, breakfast rooms, pantry, etc. But I believe there is wording someplace that states a SABC can not supply more than one kitchen.
