Board Approval for cosmetic renovation

Hi, I have done a lot of research on this and read through my coop's alteration agreement but I'm still unclear as to whether the following changes need to approved by the board and filed with management. These are all changes that do not require a permit in NYC or an architect's seal. - replace kitchen cabinets and sink, oven, fridge (fixtures remain in the same place) - lay a click lock hardwood floor over the existing hardwood floor (there is about 2 inches of clearance so i can just lay it right over the original floor) - paint the walls / ceiling tiles - replace bathroom, sink, light fixture, toilet (fixtures remain in the same place) I would appreciate any advice! I'd rather find out as much as I can before going to the management and asking Thanks!
