Sep 19, 2003 #2 JAE Structural Jun 27, 2000 15,591 I believe FEMA requires 1 square inch of vent area per 1 square foot of enclosed floor area. So if you had a house with 2400 sf you would need 2400 sq. inches of vent space or 16.667 sq. feet. This would require about 4 - 2' x 2' vents. Upvote 0 Downvote
