I’m looking for a code or standard for foundation/crawl space vent to grade clearance. Appreciate any help.
I do not think crawl spaces should be vented .
James please go to top left (Control Panel ) and put in your information so we have an idea where you live thanks Roy
Don’t think there is one. Common sense applies though. If too close, add a vent/window well.
I don’t think the general IRC has one. My state(north carolina 2012) amended IRC code has one though. Not sure how much this will help you.
WALL-VENTED CRAWL SPACES
R408.1.2 Foundation vent location.
…Vent dams shall be provided
when the bottom of the foundation vent opening is
less than 4 inches above the finished exterior grade.
