Same in Washington, and many cities that do their own inspections around Seattle (Bellvue, Kirkland etc have a common set of admendments to the NEC, that makes it easier for a contractor to work in different areas. Also if you need a business license for different cities, its is easily added to your state master business license.
Somewhat have that here. All licensing is done at state level. Cities that do have their own permitting/inspections do not issue licenses. They do require you hold a state license (can be one that state has allowed via reciprocation from other states) but most those cities still want you to register with them and submit a registration fee - of course you need to resubmit every two years when your state license needs to be renewed. Those cities can have their own amendments, but according to state law they can not lessen state requirements (which is NEC with no amendments right now). So one example is a city can't decide they want to eliminate some or all NEC AFCI requirements, but they could add more AFCI requirements if they wanted to.
How do they determine you are eligible to obtain a contractor license? Often holding a journeyman license for a certain amount of time is a determining factor in being eligible to apply to get a contractor license. Not that there isn't other ways to determine one might be eligible but is kind of the most common way of making this determination.
That is about the experience needed here to get a journeyman license (actually I think it is 5 but if you complete an approved 2 year school program they give you a free year so it can be done in 4). Having held an apprentice certificate for those years makes them easier to verify, though experience is not limited to being registered apprentice. Working in similar field for military is definitely acceptable experience.
