Finishing my basement- Code

There is no such thing as grandfathering in a new or gut and renew renovation (turning a unfinish to a finish stage). However depending where you are, there maybe a code for renovation vs new construction, which could be less strict in terms of insulation or certain things.

Those questions you are best to discuss with your inspector as he may able to give you some idea of what he will ok and what he wont

Any foamed plastic insulation requires protection except in concealed spaces. Also where used to insulate rim joists and may be exposed to the furnace return air system (i.e. where floor joists are blocked off without using drywall with sealed joints). This does go back before year 2004 so no possibility of grandfathering. Also if you're doing work on a condo the rules are more strict than a single family home - must use licensed/bonded/ insured contractors.

You can glue on R-10 blue foam boards. Then tuck tape all the seams.
