i have been trying to decide the best way to upgrade and re-new my basement bedroom....but...realize that the walls, circuits and wiring were installed about 25 years ago without a permit....there are a number of items like number of receptacles, size of receptacles and 15 amp circuit breakers with 12 awg to receptacles with 14 awg pig tails to the receptacles....and i want to add two new 15 amp circuits to go to the garage....do i go for a permit for everything????....just the garage????.....or skip the two circuits and leave the upgrade to the next owner???...i can't be the first person to deal with non-permit work..
