Is it legal for Public Housing/Section 8 to raise your rent if you get a Pell Grant for school?

Does HUD/Public Housing/Housing Authority have such right to raise your rent if a grant is given to you for school use? If they take my school money, I can't go to school. It's not like that Pell Grant is monthly income. It's a one time payment to my school and it isn't legally taxable. Thanks.
