Crawl Space Size
Is there any rule of thumb on size of crawl spaces? I am building a
three season 10'x24' porch on piers off the family room. The
family room has a cement foundation with a concrete floor. How much
room do I need between the floor joists on the porch and the dirt below
them? Do I need a vapor barrier? Does the crawl space need and what
size vents?
