If you bought your unit and there are no recorded "covenants, conditions and restrictions" recorded on your property mandating wall to wall carpeting in your unit, sentiment is that the notice now requiring a change in the "house rule" of 80 % carpeting in the unit has changed has no force and effect upon you.Although there may be a change in the "house rule", you most likely were never advised of such before close of escrow, and if you had no notice of any recorded "house rules" on the unit you purchased before close of escrow, the rule change does not appear to be a requirement that you need to adhere to given the information provided in your question.Good luck.
