There is never a duty to amend are return for an honest mistake. The reason to file an amended return is to get a refund or to pay extra tax owed thereby stopping interest from accruing.
I would just correct the address this year. Perhaps include a statement to that effect.
It would be harmless to file an amended return if you want to. I doubt the IRS will ever notice the difference or care. If they did you will have all of your records (property tax, leases, etc.) with the correct address and the same numbers.
