The kitchen would be the only room with a subpanel.

As stated in the post, the oven is already on a dedicated 30A circuit, and I’m not going to mess with that. There’s an empty void near the oven, though, and my thought was to run another 30 amp circuit up beside that to feed the subpanel and place it in that “void”. Decorating isn’t a concern for the void as there’s not much that can really go there anyway.

Definitely want to future proof it, yeah. I’m not married to 30 amp delivery to it, just used that as a reference point.

NEC requires 2 different 20 amp circuits for counter top use, 15 amps is not allowed,

That I didn’t know (or rather, haven’t read yet). Current ones are on 15 amp circuits, so I was going by that (not that previous owners seemed too concerned with “code” LOL).
