Sharing Your Home While You Care for a Spouse

Consider an example: "My husband has dementia. I can't leave him alone in the evenings anymore, the house is so quiet, and the bills keep climbing. Would it be wrong to have someone move into the spare room?"

It is not wrong to ask. Caregiving can be isolating, and some spouses and partners who care for someone at home find that another person in the house, paying rent and living an ordinary life alongside them, eases some of the strain. But home sharing in this situation needs extra care, because three people's interests are involved: yours, your spouse's, and the person who moves in.

What to know

Many people are in this position. An estimated 7.4 million Americans 65 and older are living with Alzheimer's disease in 2026, and nearly 13 million people provide unpaid care for a family member or friend with dementia¹. Many of them are spouses.

Home sharing can offer company for you, rent that helps with the household budget, a little help with ordinary household tasks if you both agree, and the comfort of another adult in the house. It cannot offer care. The person who moves in is not your spouse's caregiver. They do not help with bathing, dressing, medicine, or supervision, and they are never left in charge of your spouse. Our guide "Help Around the House Is Not Caregiving" explains that line, and it matters even more here.

The person who moves in also needs to know what they are joining. Before anyone agrees to a match, they should understand, in general terms, that your spouse has a serious illness, what they might see or hear day to day, and that nothing about your spouse's care will be asked of them.

Your spouse is part of the decision too. Involve them as much as they are able, in the way that works for them. If the home is owned jointly, or if you make decisions for your spouse under a power of attorney, talk with free legal help about who needs to agree and what paperwork you need before you sign a home sharing agreement.

Why it exists

Caregiving at home often means long days and evenings with no other adult to talk to. Friends may visit less. Getting out of the house gets harder. At the same time, costs can rise: in-home help, adult day programs, medical supplies, and the income a caregiver may give up.

A spare room that sits empty can start to look like an answer to several of those problems at once. The risk is that it also starts to look like an answer to the care problem, and that is the one it cannot solve.

Why it deserves respect

Every worry in this situation is fair. You may worry that bringing in a stranger is unfair to your spouse, who may not fully understand who this person is. You may worry that it is unfair to the home seeker, who is looking for a home, not a job. Your family may worry about safety, money, or what the neighbors will think.

It is also fair to want your own life back, a little. Caregivers who look after their own wellbeing are often better able to keep caring. Wanting company, conversation, and some help with the bills is not selfish.

What the evidence tells us

• Caregiving support exists, and it is separate from home sharing. Through the National Family Caregiver Support Program, Area Agencies on Aging offer information, counseling, support groups, training, and respite care for family caregivers². Respite care gives you planned breaks while someone trained looks after your spouse.
• Home sharing works best when care is already arranged. If your spouse's care depends on help that is not in place, the person down the hall will be tempted, or pressured, to fill the gap. In UK home share pilots, some matches ran into trouble when needs grew faster than the plan³.
• Needs change. Dementia and many serious illnesses progress. A match that works well now may need to change, or end, as care needs grow. Planning for that at the start is kinder to everyone.

Ways to lower the barrier

1. Arrange care first. Put respite, adult day programs, or in-home help in place before looking for a match, so the person who moves in is never the backup plan.
2. Be open with possible matches. Say plainly that you care for your spouse at home, what daily life looks like, and that no care will be expected. Some people will decide it is not for them. That is a good outcome, not a rejection.
3. Write the limits into your agreement. No personal care, no medical tasks, and no being left in charge of your spouse. Write down what to do in an emergency: call you, then 911.
4. Ask how to introduce a new person. A new face in the house can be confusing for someone with dementia. Your spouse's doctor or the Alzheimer's Association Helpline can suggest ways to make the change gently.
5. Check the legal and practical details. Ask free legal help about joint ownership and powers of attorney, and call your insurance agent. Our guide "The Call to Make to Your Insurance Agent" lists what to ask.
6. Plan for change. Agree ahead of time on what happens if your spouse moves to memory care, if you become ill, or if the household simply stops working for the person who moved in. Our guide "Planning for the Hospital, a Move, or the End of Life" can help.
7. Check in often. A short, honest conversation every few weeks lets everyone say, early, "This is feeling like more than we agreed."

Conversation starters

If you are a caregiving spouse talking with your family:

• "I'm not looking for someone to help with Dad's care. I'm looking for some company in the house and help with the bills."
• "Can we make sure his care is covered first, so whoever moves in isn't the backup?"
• "I'd like your help meeting anyone I'm considering."

If you are talking with a possible match:

• "My husband has dementia. He's gentle, but he may ask you the same question more than once."
• "His care is covered. Nothing about it would ever be your job."
• "If anything ever feels like too much, I want you to tell me."

The person who moves in can make the house less lonely. They cannot be the plan for your spouse's care.

Home sharing and older adults

Home sharing works at any age. Older adults are one of the fastest-growing groups sharing a home with someone who is not family⁴. For a caregiver, it can be one part of a wider plan that keeps a household going.
