Structural safety standards is pretty much independent of style and design and rarely if ever is the reason why buildings get delayed by process. The standards are well known, widespread, often rational, evaluated by experts and almost never aesthetic beyond "you need railings for stairs" and such. Even countries where building is effectively unrestricted, like Japan, has no problem in enforcing safety standards. The general safety issues of buildings tend to increase as they age, as new safety standards come into place, so making it hard to replace old buildings actually tends to decrease safety! Also they tend to be hidden so anybody at a neighborhood review meeting is not even going to understand what was done unsafely.
