Call the Authority Having Jurisdiction, and ask them. Generally the ICC codes are used as templates for legally adopted local codes. And the local/county/state government all will make changes in the ICC codes before adoption. A few more stringent, and most less stringent. For example the International Residential Code, requires fire sprinkler systems. But, very few jurisdictions have adopted that section of the code. Idaho, has it’s own plumbing code, electrical code, and mechanical code. They don’t require sanitary yard hydrants, they just this year started to require Arc Fault protection in bedrooms.
I work for the Federal Government, and we by act of Congress have adopted the ICC codes in their entirety, with only a Cabinet Secretary authorized to make modification to it. So, when we put in solar power at sites in the Wilderness, we have to put the anti back feed devices in. Even though the nearest power line is forty miles away, and will never be extended through the wilderness area.
