I have always lived in homes with slab foundations (So. Cal), so everything is up the wall into the hot box.

We recently moved to the PNW (Seattle area) and are about to close on a home.

I am planning my wire routing and since this house has about 5 foot of crawl space under it I am considering running everything under instead of dealing with the limited space in the attic.

So my question is, is this feasible to do properly or do I just not think about it any further.

Plenty of space to work, its clean and rodent free, vapor barrier covering all ground. Looks a lot more pleasant to work in versus in the attic which is very cramped.

Those of you familiar with this style of housing can you help a brother out!
