Within communities some residents are content to spend most of their time within the confines of their suite. Others find a suite too confining. They lack activities to pass the time and rely on amenities such as a lounge, work/study area or exercise room which are part of their home. For these people complete closure of amenities is comparable to a restriction on their reasonable activities.
Common areas are an extension of personal living space. It is amenities that make these smaller spaces livable for some. Without direction from government or a health department it may be counterproductive to close amenities where mandated safety standards can be maintained. As of writing, mandated safety standards include two meters distance separation which can be maintained in exercise rooms, lounges and work/study areas.
A complete prohibition on pets, smoking and short-term rentals all require majority (or greater) owner support. Closure of all amenities, in the absence of owner vote or government mandate, as protection against coronavirus, may be beyond authority of a condo board.
