Hello Harold. We were one of the first states to adopt the international family of codes, and yes, we also use the international residential code. As far as garages go, I'm not sure I follow you 100%. Are you talking about 4 garages on one lot/property? If so, you are right, the IRC doesn't care how many garages you have. Your local planning/zoning department will care, however. As far as safety goes, I don't see any hazards, assuming that the code is followed. We came from Uniform Building Code land, and used to require a fire rated seperation between the garage and living space, if attatched to each other, with a hour one wall. This is no longer a requirement. My e-mail address is Ryan@draper.ut.us Feel free to e-mail me any code questions you might have and I'll do my best to help you out with them [Linked Image]
