美国采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm currently facing some challenges in getting approval from the local authorities in St Matthews, SC, and Orange, TX. It seems there are specific regulations or documentation required that I'm struggling to navigate. I'm reaching out to see if you could assist me in understanding the process better or provide any guidance on how to move forward effectively. If you have experience dealing with the city regulations or can point me toward resources that might help streamline the approval process, that would be immensely valuable. Any insights or support you can provide would be greatly appreciated, as I'm eager to proceed without further delays. Thanks for your help!
