For SNAP, a “household” is the people who live together and usually buy and cook food together. It is not the same as everyone at your address. Roommates who shop and cook separately can each get SNAP on their own. But three groups must apply together even if they buy food separately: spouses, parents and their children under 22 who live with them, and children under 18 who live under the parental control of an adult in the home.
Getting this right matters. Household size decides your income limit and your maximum benefit.
The basic rule
Federal rule 7 CFR 273.1 defines a SNAP household as one of these:
- One person living alone
- One person who lives with others but buys and prepares food separately
- A group of people who live together and customarily buy and prepare meals together
Who must be in the same household
| Relationship | Must apply together? |
|---|---|
| Married couple | Yes, always |
| Parent and child under 22 living together (natural, adopted or step) | Yes, even if the adult child buys own food |
| Child under 18 under the parental control of an adult in the home (like a grandparent raising a grandchild) | Yes |
| Adult siblings | Only if they buy and cook together |
| Unmarried partners | Only if they buy and cook together (unless they share a child, who pulls both parents in) |
| Parent and child 22 or older | Only if they buy and cook together (with an exception for some older or disabled parents; see below) |
| Roommates | Only if they buy and cook together |
Example: Maria, 24, lives with her parents and buys her own food. She can apply alone because she’s over 22. Her brother, 20, can’t. He must be on his parents’ case even if he shops separately.
Special situations
| Situation | Rule |
|---|---|
| Boarders (pay you a reasonable amount for meals) | Can’t get SNAP on their own; they can be part of your household if you ask |
| Roomers (pay only for a room, not meals) | Can get SNAP separately |
| Live-in attendant (caregiver) | Can be a separate household |
| Foster children | Only in your household if you choose to include them |
| Someone in an institution that gives most meals | Generally not eligible, with exceptions below |
Exceptions where people can get SNAP while living in a facility include federally subsidized housing for older adults, drug and alcohol treatment centers, group homes for people with disabilities, domestic violence shelters, and homeless shelters.
The older-parent exception
A person 60 or older who can’t buy and cook their own meals because of a permanent disability can be a separate household (with their spouse), even while living with family. The catch: the other people in the home must have income at or below 165% of the poverty line. This helps when an older parent moves in with an adult child whose income would push the whole group over the limit. See SNAP for seniors and SNAP for people with disabilities.
People who live with you but can’t get SNAP
Some people are left out of the household count even though they live and eat with you:
| Person | How their income is treated |
|---|---|
| Someone disqualified for fraud, or for not meeting work rules | All of their income and resources count |
| Someone who hit the work time limit, or won’t give an SSN | Resources count; a share of their income counts |
| An ineligible noncitizen | Resources count; all or part of income counts, depending on the state |
Their being left out lowers your household size, and part of their income still counts, so your benefit can drop. For immigrant families, see SNAP for immigrants.
Why household size matters
From October 1, 2026, the maximum benefit is $306 for one person, $562 for two, $808 for three and $1,023 for four. The gross income limit for one is $1,729 a month; for four, $3,575. Adding or removing one person changes both. See SNAP eligibility and income limits and SNAP benefit amounts.
An unborn child is not counted as a household member for SNAP. Add the baby after birth; see SNAP for pregnant women.
When your household changes
Someone moving in or out is a change you may have to report, and it can raise or lower benefits. See SNAP reporting changes. If the state puts someone in your household you think shouldn’t be there, ask the caseworker which rule they used, and request a fair hearing if you disagree.
Quick answers
My boyfriend and I live together but buy food separately. Do we apply together? Not if you’re unmarried and share no children. If you have a child together, both parents and the child are one household.
Can I get SNAP if I live with my parents? Yes if you’re 22 or older and buy and cook separately. Under 22, you’re on their case.
Does a roommate’s income count against me? No, if you buy and cook separately.
