There isn't really any law that disallows housing cooperative from generating profit per se , but generally there isn't any reason for it to do so. Some very old ones actually do pay dividends and do not ask fees from owners, but that usually requires that the cooperative is debt free and has a way to generate income (i.e. owns some of the apartments/business premises that it rents out) and that it has saved up enough to pay off planned maintenances.
