Section 8 Bedroom Requirements: Can 2 Kids Share a Room?

Your housing authority decides, using its own written subsidy standards. Federal rules (24 CFR 982.402) say those standards must give the smallest number of bedrooms needed to house the family without overcrowding, must be consistent with the housing quality space requirements, and must be applied the same way to every family of like size and composition. The number that comes out is the family unit size printed on your voucher.

Rules every housing authority must follow

• A single person gets a studio or one-bedroom voucher (the housing authority chooses which), unless a live-in aide lives with them.
• A pregnant woman with no other household members is treated as a two-person family.
• A child temporarily away in foster care still counts as a family member.
• An approved live-in aide (for a family member who is disabled or at least 50) is counted.
• Exceptions to the standards are allowed when justified by the age, sex, health, disability or relationship of family members, or other personal circumstances.

Can two kids share a bedroom?

Federal rules don't say. Whether two children share a room, and at what ages children of the opposite sex get separate rooms, is set by your housing authority's subsidy standards. Ask for that section of its administrative plan, or use our occupancy calculator to see how common standards would size your household.

Is "two heartbeats per room" a law?

No. "Two heartbeats per room" is an informal phrase, not a federal rule. The closest federal statement is HUD's 1998 fair housing policy on occupancy standards (63 FR 70256), which says "an occupancy policy of two persons in a bedroom, as a general rule, is reasonable under the Fair Housing Act". That is a rebuttable guideline for landlords' occupancy limits, and HUD weighs the size of the bedrooms and unit, the ages of children, the layout (a den or study, for example), the capacity of systems such as septic, and state and local law. It does not set your voucher size; your housing authority's subsidy standards do.

Renting a bigger or smaller unit than your voucher

You can rent a unit with a different number of bedrooms, but the payment standard used for your subsidy is the lower of the standard for your family unit size and the standard for the unit you rent (982.402(c); 982.505(c)(1)).

• Bigger unit: a family with a two-bedroom voucher that rents a three-bedroom unit is still capped at the two-bedroom payment standard, so it pays any extra rent itself.
• Smaller unit: a family with a three-bedroom voucher that rents a two-bedroom unit gets the two-bedroom payment standard. The unit still has to pass inspection and meet local occupancy rules.

To see the gap between bedroom sizes in your area, look up the payment standards for any ZIP code with our rent limits lookup, or read voucher amounts by bedroom size.

Asking for an extra bedroom

If a household member needs a separate room because of a disability, for example for medical equipment or a live-in aide, ask the housing authority for a larger family unit size as a reasonable accommodation. Put the request in writing with supporting documentation. The exception in 982.402(b)(8) lets the housing authority grant it, but a single person who is not elderly, disabled or a remaining family member cannot be moved above a one-bedroom this way.
