urethane foam insulation

Can anyone tell me what the laws/codes are in regards to the spray foam insulation in a crawl space? I had my concrete walls in my crawl space covered with the foam but now I am reading that its required to have drywall over top of it due to fire hazards. Am I really going to have to try and build walls in the crawl space or is there any other alternative short of offering potential buyers a credit for the work....please tell me I can paint some type of a coating on it or something....

thanks as always

I'm pretty sure (not a lawyer or builder tho) that any type of flammable insulation must be covered only in potential living areas and also a garage. Ive never heard of a requirement to cover it in an actual crawlspace insulation under a house or whatever. The only exception i can think of is when you have a crawlspace used for storage like behind a kneewall that is inside the house. I have one of these and yes I covered the insulation with plywood but only cause it has a door and again im using it for storage.
