I am really confused with the language of this credit , can you please clarify the below
1- Does EACH unit have to be sealed and Compartmentalized or only Residential units allowing smoking? in that case there will be two kinds of lease agreement i believe one for the specified smoking unites allowing smoking and the other for the units prohibiting smoking ? also what if the unit is sold not rent ? how this would be enforced then?

2- do i have to Compartmentalize the WHOLE residential unit (apartment) , or only a specific room dedicated for smoking inside each residential unit ?

3- by common area do they mean areas used by all building occupants , or you mean areas in each residential unit such as the living room or dining room ?
