What is this tree? I’m just wondering so I know if it’s grows big to block a view.
There are many types (species) of bamboo, but usually they are bought from the garden centers (assuming that bamboo is not native to your region), which limits the number of available species.
One popular species is Fargesia 'Rufa' which is a clumping bamboo and is therefore not invasive. It is hard to tell if this species is the one your neighbor has planted. You might wanna talk to your neighbor, if possible, and ask him/her if this is clumping bamboo or of the invasive type.
