Disputes with your neighbour who is a tenant
From your side, it does not matter if the neighbour causing you grief
is an owner, a tenant or a short-term renter but it does for the
manager and the board.
The condo unit owner is responsible for the actions of his tenants,
their guests and their visitors if any of the above break the
declaration, by-laws or rules.
So if a tenant is acting like a jerk, and won't stop, it is the unit owner who the condo corporation takes to court.
If you are the tenant's landlord
If you are renting out your unit, make sure the management office has
your latest contact information. If your tenant is acting up, you want
to be made aware of it immediately.
If you think that the worse thing your tenant can do to you is stop
paying their rent or damaging your unit, you are mistaken. In my
opinion, the worse thing your tenant can do to you is to provoke the
board into commencing legal action against you.
If it looks like there will be legal issues with the condo corporation, you should
immediately contact a lawyer who is experienced in condominium law. You
may need to start eviction proceedings quickly.
