We added a bathroom shower and kitchenette (no stove).  

City defines a kitchen is a room with a stove.  

What I'm learning to do now is roll with the punches, and use a little bit of down time to actually use the stove I put in.

If you are not using electric heat then you do not need 200A service (ours have natural gas for heat, stove and hot water).I recommend you get a licensed electrician to diagnose the problem.

Everything else, pulling wires, ungrading circuits, bathroms, kitchens, electric stove lines, water heater lines and so on I did, but I've done wiring for 30 years and I wire to code anyway.Just have it inspected before you add insulation and sheet rock, so the inspector can see the work and can yell at you and you can fix the problem pretty easily.

Wood stoves, generators, tractors clearing everything.
