In general, the Property Owner is responsible to pay for all routine maintenance on a rental property.
The main exception is if the damage is a result of mistreatment by the tenants.
For example, a kitchen cupboard hinge that is worn out from normal daily use is considered maintenance for the owner to fix. On the other hand, if the hinge were torn from its fixture by unnecessary force, this would not be considered normal use and therefore the tenant’s responsibility to fix.
