Boy, if you just built the house a year ago your electrician did you no favors.:confused2:
He or she should have discussed with you future uses and set up your panel accordingly along with some external runs or at a min some conduit runs.
My electrician suggested and I did 4 outlets and 4 lights in the crawl space, a RV plug on the outside of the barn, outside outlets along with some on small 4x4 post in 2 of the flower beds, a dedicated circuit for a pool pump with a 30' coil of wire under the deck, a dedicated circuit with a 30' coil of wire for a future hot tub which I did install, and a 50 amp twist lock hook up and panel whole house/panel transfer switch for generator hook up. It was not much extra money, maybe $600 and well worth it.
