PLEASE HELP...I have an issue with a set of plans requiring 12" anchor bolts for a 7' post light in a multi-family application. I'm in So Cal and thought that if a post light (13W lantern on a 3"OD x 7' post)was under 7' in height then the footing did not need to be engineered and it could be installed like a fence post and did not require a cement footing? I dug a 3' deep hole aprox 18" in diameter and using cement but the engineer says it has to be pad mounted with 12" anchor bolts??? If anyone knows a building code or can help me out on this it would be greatly appreciated..
