No, there is no such city or county code. Unless the landlord is undergoing major construction which touches/damages the ducts or ceiling, there is no need to remove the asbestos in the ducts nor to remove the popcorn ceiling. As such, you do not have a legal basis to sue the landlord nor to claim "uninhabitability" in order to terminate a lease early.
