The insurance should cover the damage whether it was done by a tenant or an owner.
Any excess could be sheeted home to the landlord lot owner, particularly if his tenants have caused previous insurance claims.
As SH advises, if it all gets nasty and you need to go to the tribunal it is wise to document and photograph as much as you can.
All other damage done by the tenants should be the responsibility of the landlord lot owner. The landlord lot owner is responsible for the damage caused by his tenants, visitors, invitees etc.
There is no ‘contract’ between the OC and the tenant therefore the OC cannot chase the tenant for any damages.
It is the landlord lot owner who has contracted with the OC to abide by the by-laws when he purchased his lot including the responsibility for his tenants, visitors invitees etc.
The tenant then contracts with the landlord to abide by the by-laws when they sign their lease.
If the landlord lot owner has a problem with that after he has paid the OC for the tenant’s damages, then he can always chase the tenants to collect the money that he has paid to the OC on the tenant’s behalf. That is what a bond is for, and that is why there are tenant ‘blacklists’.
