the optimum balance between public safety and reasonable cost.
There is a kernel of truth in that statement. On the balance beam is not safety and cost but actually consumer and provider. While consumers are cognizant of costs they will land on safety. Providers are focused on their own expense and will ignore safety until they can't.
Suppose some BO's "do the right thing" extra-code requirement costs more than "just" meeting the code
Your argument brings up the opposite of the usual BOs intervention, Ninety-nine of a hundred BO code interpretations water down a code rather than add some extraneous requirement. I guess that I am saying that you are tilting at windmills.
When you tell an owner that he/she/they have to do more than what the code requires, you are making them spend more money than what the law requires.
You deal with owners? I deal with contractors and developers. I make the argument that what I am requiring is code.... perhaps not the code as they understand it, but code none the less.
Here is an example of me attempting to enforce what is not expressly delineated in written code.
A 25,000 square foot dwelling foundation was built without removing the form boards until days after placing the concrete. At the raised floor framing inspection I found that the forms had not been removed below the adjacent grade. The footings were three to four feet in depth. Well then, at each footing inspection I write a correction notice instructing the contractor to make sure that all of the wood form work is removed. I wrote a correction to remove the form boards on both sides of the foundation to the full depth. I was challenged. I provided the following code reference:
R408.5 Removal of debris. The under-floor grade shall be cleaned of all vegetation and organic material. Wood forms used for placing concrete shall be removed before a building is occupied or used for any purpose. Construction materials shall be removed before a building is occupied or used for any purpose.
I was overruled by an assistant office manager. He pointed out that code section R408 is restricted to the underfloor area so form boards on the exterior of the foundation can remain. I pointed out that the Pasadena California area has a significant problem with subterranean termites. I was, and still am, convinced that although section R408 is Under-Floor Space, it can be correctly applied to form boards on the exterior of the building. Naive I was.
That ruling against my correction did not alleviate the contractor's problem with the form boards on the inside of the foundation. The contractor estimated that it would cost $250k to remove the form boards. The BO decided that because the code is silent on the form boards on the exterior of the foundation, there is obviously not a problem with form boards left underground on the inside of the foundation. He determined that
"Wood forms used for placing concrete shall be removed" refers to form boards that were stripped from the concrete and not removed from the area of the underfloor.
Worth noting is that the manager contacted the property owner who happened to be in Europe at the time. The manager explained the potential expense and delay if the correction stands. The manager downplayed the potential termite infestation. I figure he was giving the owner a heads-up to get a termite exterminator on retainer.
I was instructed that hence forth I was not allowed to require form boards to be removed unless they were "debris." and then i was replaced as the inspector. Getting replaced never bothered me. I still haven't learned to gleefully accept asinine rulings and I've experienced plenty.
