Hi guys, my question is simple. I was wondering if I need to have a permit and inspection done in order for me to install my standup shower, toilet and sink in my half duplex in Edmonton, Alberta Canada. I was hoping on doing this work myself. When I bought this home, we paid the builder extra to have the roughed in plumbing done for us in the basement. And now 4 years later I am wanting to set up the bathroom in the basement. I haven't opened the covers in the floor as yet. Any tips and comments would be greatly appreciated. Thanks in advance.
