no smoking in common areas
Smoking of tobacco and other products is not allowed in areas shared by multiple tenants or users.
A prohibition against smoking in common areas indicates that smoking of cigarettes, cigars, pipes, and any other medium of consuming tobacco or drug smoke is prohibited in the areas of a structure, or property which are accessible to multiple tenants or users. This means that smoking is allowed within individual units, or at least within certain individual units at the tenant's discretion.
The shared spaces are smoke-free, while smoking remains allowed in individual units or at least some units at the tenant's discretion. That unit allowance is part of this definition.
A no-smoking policy covers private units as well as common areas. Smoking only in designated areas requires a designated smoking area within the commonly accessible property.
