This is for NEC 2020 in state of Florida. My understanding is that surge protection is required for areas like dwelling/hotels/nursing homes or areas with critical power. What about other commercial areas such as small office building or a small daycare or a teaching facility or shopping center with (No emergency backup)?

NEC 230.67 is for dwelling from my understanding.

Thank you,

You are correct. There is no requirement for surge protection on non-dwelling services.

There might be requirements based on certain equipment elsewhere in the code. Like you mentioned with emergency systems.
