There are no hard and fast answers for all your questions that you're asking here. There are too many variables, and your questions are too vague, and this is not the proper venue for establishing requirements for a tower. So you need to lower your expectations on what you're going to achieve here at RR. That being said...
Yes, all towers need to be inspected periodically. Regulations for construction and inspection are generally local. Painting and lighting requirements are both FAA and FCC jurisdiction, as is tower registration. Some towers may require federal permits to construct, as well as local permits. A lot of that is driven by tower height, location, and proximity to an airport. And be careful what you use as a definition of an airport.
Regulations on tower maintenance vary. Lighting falls under federal jurisdiction, and is strict enough that if the tower is lighted, you have to make phone calls if a light bulb burns out. Same with painting... Federal guidelines will dictate whether the tower needs to be painted. Tower manufacturers may require annual inspections, whereas there may be no provision in local law to inspect. But heaven help you if the tower falls, kills someone, and you can't show that you had the manufacturer (but not regulated) recommended periodic tower maintenance done.
There may be OSHA requirements on maintenance of parts of the tower. Does it need a safety climb installed? That would require periodic inspection as well. OSHA requires that tower climbers be trained and certified. That's expensive. Does the tower require FAA and FCC registration? That falls under federal guidelines, and no one here can answer that for you.
Are you confused yet?
