All owners can use and enjoy all parts of the common property at all times, provided any one owner do not do anything that prevent another owner form using or enjoying the same.
Tricky! For example, if there is one piece of common property that can be used to park a single car; then all owners are entitled to use it. However, in reality only car can be parked on this piece of property at a time.
A more obvious example: An owner experience a car breakdown and need to get his vehicle fixed for the next day of work. He proceeds to dismantle the problematic part and discovers the problem is bigger than he thinks. He works until late into the night, in the basement parking area. The sleep of a number of occupants is disturbed. This is clearly an example of an owner using common property in an unacceptable way.
Another problematic area is the contrasting needs and preferances of children (of various ages) versus adults (in various degrees of maturing). Kids wants to play, run and shout, whereas aging adults want peace and quiet.
