Can an owner change windows without approval from the Condo Board? Our CCRs says that the owner is only responsible for the glass, and on Board Repair and Maintain Section says that the board is responsible for all external surfaces but nothing specific on windows frames, and our Rules and Regs, says no modifications to external surfaces. The frame in question is totally different that the rest of the units, Can he get away with it with the CCRs and Rules and Regs being so vague?
