How to Add Someone to Your Section 8 Voucher (Step by Step)
Your partner wants to move in. Or your adult son lost his apartment, or your mother needs care. You want to help, but you’re scared of losing your voucher. That fear is real, because an unapproved person living with you can cost you your assistance.
The good news is that you can add someone to Section 8 the right way. For a new baby, an adopted child, or a child in your custody, tell your housing authority. For anyone else, you need written approval first. Your agency checks the person and then recalculates your rent.
This guide shows the steps, the papers you need, and how your rent may change. It also covers why requests get denied.
Can you add someone to a Section 8 voucher?
Yes. Under 24 CFR 982.551(h)(2), your housing authority must approve everyone who lives in your unit. For a birth, adoption, or court-awarded custody of a child, you only need to tell the agency promptly. To add anyone else, like a partner or adult child, ask for approval first. Then wait for a yes.
| Who you want to add | What you must do |
|---|---|
| A newborn baby | Tell your agency promptly |
| An adopted child | Tell your agency promptly |
| A child you got custody of by court order | Tell your agency promptly |
| A partner, spouse, or adult child | Ask for approval first |
| A parent, sibling, or other relative | Ask for approval first |
| A foster child or live-in aide | Ask for approval first |

Takeaway: tell the agency about new children, and ask before anyone else moves in.
How do I add someone to Section 8 step by step?
Ask your caseworker for the agency’s “add a household member” form. Fill it out and attach the new person’s ID, Social Security card, birth certificate, and income proof. Your agency screens the person and checks your lease. It then sends you a written decision and, if approved, a new rent amount. The person moves in only after approval.
- Ask for the form. Each agency has its own. Call, email, or visit your caseworker.
- Check your lease. Your lease may also require your landlord’s OK for a new adult.
- Gather documents. See the checklist below.
- Submit the request in writing. Keep a copy with the date.
- Wait for screening. The agency checks the new adult’s background.
- Get a written decision. Don’t let the person move in before approval.
- Get your new rent amount. The agency adds the new person’s income.
Takeaway: when you add someone to Section 8, written approval comes first and moving in comes second.
What documents do I need to add a household member?
Expect to give the new person’s photo ID, Social Security card, birth certificate, and proof of income. You may also need proof of the relationship, such as a marriage or birth certificate, and signed consent forms. Federal rules require a Social Security number for most new members, with extra time for young children.
Use this checklist and confirm it with your agency:
- ☐ Photo ID (for adults)
- ☐ Social Security card or other proof of the number
- ☐ Birth certificate
- ☐ Proof of income: pay stubs, benefit letters, or unemployment papers
- ☐ Proof of assets, such as bank statements
- ☐ Marriage certificate, custody order, or adoption papers, if they apply
- ☐ Citizenship or immigration declaration
- ☐ Signed consent and release forms
- ☐ Your landlord’s written OK, if your lease requires it
Does a child under 6 have no Social Security number yet? Under 24 CFR 5.216(e), you get 90 days to provide it. Your agency may give one more 90 days in some cases. The child counts as part of your household while you wait.
Takeaway: a complete packet is the fastest way to add someone to Section 8.
Will my rent go up if I add someone to Section 8?
Usually, if the new person has income. Your rent share is based on your whole household’s income. So adding a working adult or someone with benefits can raise it. Adding a child often lowers it, because each dependent gets a deduction. Your agency will send you a new rent amount after it approves the change.
| Who you add | Likely effect on your rent share |
|---|---|
| An adult with a job or benefits | Goes up |
| An adult with no income | Little or no change |
| A child (a dependent) | Often goes down a little |
| A live-in aide | Their income isn’t counted |
Your voucher size may change too. Your agency checks whether you now qualify for more bedrooms. Read our Section 8 bedroom size guide for how that works.
Takeaway: plan for a higher rent share if the new person earns money.
Can my partner live with me on Section 8?
Yes, but only after your housing authority approves them. Your partner must go through the same screening as any new adult and report their income. If they live with you without approval, that can break your family obligations. Your agency could then end your assistance. Ask before they move in, not after.
People on Reddit often ask about this, because of rent fears. Here is how to think about it:
- Your partner’s income counts. Your share of the rent may go up.
- You may need a bigger unit. Your voucher size may change.
- Breaking up later is possible. If they move out, report it promptly under 24 CFR 982.551(h)(3).
- Hiding them is risky. An unapproved adult in the unit is grounds to end assistance.
Takeaway: approval protects you, while hiding someone puts your voucher at risk.
Why would a request to add someone be denied?
Agencies may deny a new adult for certain criminal history, owing money to a housing program, or missing documents. Federal rules always bar two groups from assisted households. These are anyone on a lifetime sex offender registry, and anyone convicted of making meth in federally assisted housing. Ask for the reason in writing.
| Reason | Can you fix it? |
|---|---|
| Missing papers | Yes, send what’s missing |
| Owes money to a housing authority | Often, with a repayment plan |
| Recent drug or violent criminal activity | Sometimes, with proof of change |
| Lifetime sex offender registration | No, federal rules bar it |
| Meth production in assisted housing | No, federal rules bar it |
| Unit too small for the larger family | You may need to move |
Source: 24 CFR 982.553 sets these criminal history rules for admission. Your agency’s Administrative Plan explains how it screens new adults.
If a disability is involved, such as needing a live-in aide, ask for a reasonable accommodation. See our reasonable accommodation letter guide.
Takeaway: get the reason in writing so you know what you can fix.
What happens if someone lives with me without approval?
Letting an unapproved person live in your unit breaks your family obligations under 24 CFR 982.551(h)(2). Your agency can end your assistance for that. It may also ask you to repay assistance if their income wasn’t reported. If this has already happened, report it now. You can ask for an informal hearing if the agency moves to end your voucher.
Guests are different from household members. Your agency’s Administrative Plan sets how long a guest can stay. Ask your caseworker for the guest policy before anyone stays for more than a few days.
If your agency sends a termination notice, read our Section 8 informal hearing guide. It explains your rights and the deadline to ask.
Takeaway: report it yourself before the agency finds out another way.

Frequently asked questions
Can you add someone to a Section 8 voucher?
Yes. Federal rules let you add a household member with your housing authority’s approval. For a birth, adoption, or court-awarded custody, you only have to tell the agency. For anyone else, ask for approval in writing first. The agency screens the person and updates your rent.
How long does it take to add someone to Section 8?
There’s no single federal deadline. It depends on your agency and how complete your paperwork is. Screening and income checks take time. Submit everything at once, keep copies, and follow up in writing. Don’t let the person move in until you get written approval.
Can I add my boyfriend or girlfriend to my Section 8?
Yes, if your housing authority approves them. They must pass screening and report their income, which may raise your rent share. Your lease may also need your landlord’s OK. Living together without approval breaks your family obligations and can cost you your voucher.
Can I add my adult child back to my Section 8?
Usually yes, with approval. Your adult child is screened like any new adult, and their income counts toward your rent. Some agencies have special rules for adults who left and want to return. Ask your caseworker for the agency’s policy before your child moves back in.
Do I need approval to add a new baby to Section 8?
No. Under 24 CFR 982.551(h)(2), you must promptly tell your agency about a birth, adoption, or court-awarded custody. You don’t need approval first. Provide the birth certificate and Social Security number. If your baby doesn’t have one yet, you have 90 days.
Can I add someone who is not a citizen?
Yes. Each member declares their citizenship or immigration status. If someone doesn’t have eligible status, your family can still live together. Your assistance may be reduced, or prorated, under 24 CFR 5.520. Ask your agency how it would affect your rent before you apply.
