Since it's a code requirement I think it is relative to egress, since the codes wouldn't address moving equipment and furniture. But maybe someone else has some insight?rd1man said:Hello All,I'm the new guy here. I am a semi-retired general contractor, more retired than working. Anyway, I have a question concerning door sizes. Since all of my code books are kinda outdated, maybe I get some information with you guys. I know that most or all single family homes generally require one 2/8x6/8 hinged and one 3/0x6/8 hinged entry/exit doors. My question is what is the primary purpose of the larger of the two doors. I'm thinking equip/furniture moving, or is it sized specifically for egress?
