Definition : Odors

New co-owners have recently moved in. They cook a lot, a lot, with a lot of spices and other condiments. As soon as it gets out of the elevator an intense smell runs through the entire corridor. It is unbearable. Question: Is there a regulation/section of law regarding this inconvenience?

An apartment held in divided co-ownership caught your attention. You seriously consider buying it, but before making a commitment, you would like more information about the neighborhood. To obtain additional information to that supplied by the co-owner seller, it will often be necessary to conduct your own survey. This is important on account of the possibility of abnormal neighborhood annoyances caused by noise, odors and smoke, the main cause of co-owners’ conflicts.  

The co-owner of the apartment below ours uses the barbecue on his balcony almost daily. The smoke and smell of grilled meat are so strong that I no longer wish to use my balcony. These fumes force me to keep my patio door and my windows closed. Question: Are there legal provisions to assert my rights?
