Contact the public housing agency (PHA) that administers the Section 8 program in your area. This is most often the same entity that issued you your Section 8 voucher in the first place. If you cannot locate your agency's contact information, you can search for it at HUD's website.
Notify your PHA of any key changes to your household or financial situation that may impact your program status. If you are unsure about a change, call your PHA and ask whether they need to know about it. For instance, as the Code of Federal Regulations indicates, you must let your PHA know if a family member moves out of your unit. As your household size changes, so does your income eligibility for Section 8 assistance.
Bring requested documents to your PHA office. For example, if your income increases or decreases, your PHA will likely want to see proof in the form of a letter from your employer, a paycheck stub or another financial document. Follow your PHA's instructions in this regard.
