It must be a royal pain that you have a building all designed, and then somebody comes along, and says it has to be designed to a very old, 1930's building code. California truly needs a general building code, with importance factors for various classes of buildings. But really, a good code (such as Canada's) ensures that there will be no loss of life in public buildings. After all, those little kiddies spend most of their lives at the mall, and home!
Patchwork building codes never did anybody any favours.
