Please give notice for work being done

Please give notice for work that is being done on buildings or inside units. Came home to a notice that painting is being done, and to remove all items from porch-- work 08/25-09/02. Well today is the 25th, can we be given a heads up?? Especially for people who do not live here full time, would be nice if they had time to arrange for these things. Same thing happened a few months ago with the fire sprinklers- we were told the night before that contractors would be entering our unit the next day, with or without our presence. PLEASE give notice.
