Thanks for all the replies. Have my approval from the HOA pending, so hoepfully that one goes through ok. I would prefer to build according to the code, which I understand is the International Residential Code from 2003 (the current one for the state of Texas). Is there any way to see this document with out spending the big $$$ to buy a copy? I assume my permit application will have to describe how it meets the code or do I just submitt a drawing of the structure and then during an inspection they will make sure it meets the code?
