I prefer that receptacles and lighting in a room are on separate circuits. This way if you need to work on the receptacle circuit you still have lights and if you need to work on the lighting circuit you may connect a portable lamp to the receptacle circuit.Is it reasonable to take this approach rather then try to incorporate the ceiling lights into the circuits of each room and outlet?
I would use at least two independent circuits, more is always better.
You may be able to use "two-circuit" breakers in your panel which would allow for two circuits in a one-inch space. This is the easiest and least expensive fix.The House has updated 200 amp service with breaker box (a little small, 20 1" slots)
