Crowded nest? How parents and their adult kids can live together in peace

With record numbers of adult children living at home with their parents, how can this arrangement work for everyone? Set ground rules from the off, respect each other’s privacy, and don’t revert to type, say the experts

Whether they are fresh out of university and looking for a job, have recently been made redundant, are saving to buy a home or newly divorced, it’s becoming increasingly common for adult children to live at home with their parents. According to the Office for National Statistics (ONS), 35% of men and 22% of women aged between 20 and 34 were living with their parents in 2025.

I speak from experience: my younger sister lived at home with my mother for two years while she did her PhD, and I moved home for almost three years after becoming a single mother postpartum. In both of our situations, it would have been good to have some practical advice to make it work, with tensions sometimes running high and arguments inevitable.

If parents and their adult children are going to coexist successfully, honest communication is essential from the outset. How long do children expect to stay? Will they contribute financially? Will they do any housework? Are guests allowed? Difficulties will arise if you aren’t clear about these boundaries from the off.

“You won’t be able to anticipate every point of tension in advance, but you might want to discuss typical frictions like noise and overnight guests,” says Anita Cleare, a parenting expert and author of How to Get Your Teenager Out of Their Bedroom. “Parents should aim for a balance between making adult children feel welcome and maintaining their own mental and financial wellbeing.”

Parenting expert Sue Atkins, whose grownup children have both lived with her for periods, recommends writing down everything you want to say first, so that you can stay focused – and, crucially, to pick your moment. “It’s all about your tone of voice and your attitude,” she says. “If you do it when you’re angry or frustrated, that’s the wrong time. I always say: ‘Strike when the iron is cold.’”

Both parents and adult children can fall into the trap of reverting to childhood dynamics. Parents find children annoying and untidy, and feel free to comment on their lifestyles (“You’re not going out in that?” “What time will you be back?” “That’s a waste of money,” etc), while children regress into teenagers, expecting Mum and Dad to do the laundry, housework and cooking.

“The biggest trap adult children fall into when returning to live with parents is to demand the rights of adulthood while still expecting to enjoy the privileges of a child,” says Cleare. “For example, expecting their parents to provide household comforts while insisting on sticking to their own separate daily schedule. Vice versa: now that your child is an adult, you don’t have the right to know where they are at all times, what they are doing or what they are thinking. Voicing your opinion on how they should be going about life differently will send you right back into parent-teenager dynamics.”

Instead, conceive of it as more of a housemate situation. “It can help to think of your adult child as a friend who is staying with you, rather than as your child,” says Cleare. “Parent-child dynamics have a power imbalance – parents tell children what to do (and children assert their power by not cooperating). Friendships tend to be more equal. Aim for discussion and collaboration rather than rigid rule-setting. Set your parameters, but then treat your adult child as a problem-solver by inviting their views and ideas.” For the adult child, they can also consider what being a good housemate means: chiefly, pulling their weight by doing chores without being asked.

If an adult child is moving back home after living away for some time – perhaps even in their own home – then they will have accumulated a lot of “stuff”.

Kate Edmondson, the founder of Home Edited, a professional organisation service, recommends first agreeing on where belongings will be stored and how much space is realistically available. “Ask them to go through their belongings and make decisions about what is genuinely worth storing,” she says. “Make sure they know what they have and where it is. Clearly labelled, categorised boxes make belongings much easier for them to access without having to pull apart an entire storage area. If you’re storing a larger volume, encourage them to keep their own simple inventory on their phone.”

While you might not agree on politics, what to watch on TV, or other hot topics, see this as an opportunity to spend quality time together.

“Build some new family traditions,” suggests Cleare. “Families are glued together by spending time together – whether that’s eating or cooking, watching TV or sport, or shopping. So try to find new ways to spend time doing things you all enjoy.”

There’s no reason you can’t view the experience as a positive one. “I think you have to see living together as a springboard, not a destination,” advises Atkins. “When you come through the other side, you may realise you gained a lot from it and are closer.”

Whether you are already in a relationship, or looking to date, there’s no denying that living with your parents puts a dampener on romance. Elinor Harvey, a psychotherapist at The Relationship Therapy Practice, says communication and boundaries are key.

“A family might agree that Friday night is the adult child’s night to go out and date, and that they can bring someone home afterwards,” she says. “Another family might be more flexible, but simply want advance notice if someone is coming back. There doesn’t have to be one set of ground rules that works for everyone. What matters is agreeing to the rules early and making sure everyone understands them.” It’s also important to remember that if the adult child’s parents are in a couple – whether with each other or a new partner – then they will want time alone for their relationship too.

If parents don’t want their child to bring anybody back, and that’s a deal-breaker for the adult child, the arrangement is simply not going to work.

If there’s one thing that adult children and parents are likely to fall out over, it’s privacy. After all, many have been living away from home – whether at university halls, in shared housing, or with an ex-partner – and won’t appreciate parents walking into their room without knocking. The same goes for asking about their whereabouts or who they are seeing – though it is always considerate for adult children to check in and offer a little reassurance, rather than turning up half-cut at 3am after a night out and waking everyone up.

“They’re adults now,” says Atkins. “You don’t just walk into their bedroom because they’re your children. You have to respect their personal space and remember that they may have been independent for years.”

As tempting as it is to try to swoop in and save adult children living at home in less than ideal circumstances, Cleare advises against playing the hero. “When adults move back home, it is often because something isn’t going right in their lives,” she says. “They might have lost their job or relationship, or be struggling to cope in some way. The temptation is for parents to see these issues as something their adult child needs our advice on and to overstep the mark.”

Instead, parents can try to boost their child’s confidence by taking an interest without meddling. “Be mindful not to rescue them – empower them,” says Atkins. “If it’s budgeting and money, you might say: ‘Can I give you a hand? This is how we do it.’ You’re helping them develop the skills to move forward rather than taking over. Don’t judge them or patronise them. Ask open-ended questions: ‘What can we do to support you?’ And use ‘I’ statements. Say: ‘I’m feeling … ’ rather than: ‘You always … ’”

When an adult child moves back in with a parent, it can cause undue pressure on household budgets, particularly for single parents. And as more than 38% of people who married in England and Wales in 1995 had divorced by 2015, according to the ONS, this is clearly an issue for many families.

Beverley Sayers, a mediator who works with the Family Mediation Council, has encountered parents who are struggling to support an adult child after a separation or divorce. “There’s an unrealistic idea that you don’t have to continue paying for children once they reach 18,” she says. “I often advise the young person to have a conversation with the parent they don’t live with and ask: ‘Can I have some funds to help with this situation so I can contribute to the household?’”
