The declaration of co-ownership is a contract that orchestrates and regulates the lives of co-owners, lessees and other occupants of the immovable. It represents the guideline for everyone who lives in the immovable.The declaration of co-ownership provides, systematically, that it is up to the board of directors to have its content abided to. However, it happens that people break the rules, in particular by a non-compliant use of a private portion with regard to the destination of the immovable, a noise nuisance and work carried out in violation of the by the laws of the immovable. Other examples illustrate the problems that can occur in the co-ownership, such as an encroachment on a common portion or the improper installation of a floor covering. Anyone who does not abide to the declaration of co-ownership is liable, inter alia, to a legal recourse based on article 1080 of the Civil Code of Quebec . This action may be brought by a co-owner or the syndicate.
In principle, co-owners have the right to enjoy their private portion as they see fit. This use nevertheless has limits, namely that the right of enjoyment must not exceed normal neighborhood inconveniences. If the nuisance caused by an occupant of the immovable becomes excessive, it constitutes an abnormal neighborhood disturbance. This is the case in the event of non-compliance with clauses relating to the peaceful enjoyment of private portions, stipulated in the by-laws of the immovable. However, an abnormal neighborhood disturbance does not systematically constitute a violation of the declaration of co-ownership, as in some circumstances, this type of nuisance can be sanctioned, even if the perpetrator has not committed any fault.
