In Georgia it is not uncommon for the HOA to have keys for units in a condo or townhouse for the limited purpose of attending to emergencies, such as burst pipes in winter, or fires, etc... But otherwise, there is no right to access without advance notice and a valid reason (ie pest control spraying). This must also be specified in the covenants. The Board cannot just one day decide they want to start inspecting units. The Board's authority comes from the covenants and they are not supposed to supercede that authority. The bylaws should set out how board members are appointed if all the positions aren't filled at an election or if someone resigns. They may also have a means for removing a board member. Take a look. And if enough of the HOA members are in agreement with your way of thinking, maybe a group of you could get together and hire an attorney to force the board to begin acting appropriately, or to remove any board memebrs who have acted inappropriately. If any officer or director is acting outside the scope of their authotrity, you may have other causes of action, such as trespass, which you may want to speak to an attorney about.
