OP means Original Poster.
Otherwise Jimmy and FlatChatFan are right, if you live in an apartment building you need to take that into account when you are planning to do something that may cause a racket. The key consideration is reasonableness, i.e. what is reasonable – and that is something that needs to be considered by both parties. Provided someone plans a renovation properly, gives notice to all the residents and keeps any noise between certain hours, it would be unreasonable for the residents to prevent those renovations occurring.
In this case I would be asking if the downstairs neighbour has sought approval for his renovations, if he hasn’t then you may be able to stop him, depending on what he is doing. It is a standard condition of OC approval of renovations that work only be carried out on certain days between certain hours.
