Like any homeowner, co-op owners are always planning improvements to their homes. But one major difference between a cooperator and a homeowner is that the cooperator just can’t do whatever and whenever he/she wants. For example, if if the co-op owner renovates a bathroom, he or she runs the risk of flooding the downstairs neighbor. Oftentimes any work requires notification and approval of the board. With that in mind, when can a shareholder feel free to act and when should they notify and seek the permission of the board and corporation to alter their home?
