What brand of load center do you have, Keith.
2 wires into a single pole breaker are completely allowed by NEC unless a certain brand or style of breaker does not allow this.
Do you have local electrical code?
BTW, nice back yard. Been looking for a house and I need some room for a shed or wood pile. These places where you can have a meal with the neighbor and not leave your own house is too close for me.
I'll bet your insurance doesn't allow a duplex rental?
