How Often Will You Actually See Your Parents If They Move Into an ADU? (The Visit Math)

Watch: Psychologist Explains Why Family ADUs Go Wrong (Dr. Amber Bartlett)

You already call your parents every week, and maybe you drive over for Sunday dinner. You also go to birthdays, and you go over and help when they need it. So when the idea of building them an ADU in your backyard comes up, you're not sure you see the point because you already see them all the time. Would it really make a difference if you spent six figures on another home for them in your backyard, or would you just be paying a lot of money for things to basically be the same?

My name is Buz Artiano, founder of BuildX. We've built dozens of ADUs all over Massachusetts, but most of our projects have been on the South Shore and in Plymouth County. We handle all of the design, the septic evaluation, the board-of-health approvals, permitting, and construction ourselves, so we are the only team you need. We walk every family through all of those steps. In our experience, we've learned that a backyard ADU for aging parents is really about family, not logistics. The construction is the easy part honestly. What you need to decide is what kind of relationship you want with your parents for the next 10 or 20 years.

Most families focus on the cost of the build, down to every dollar, but the family benefit just sorta gets brushed off, as if it can't be measured, but it can. The one number a lot of people forget about is the time you'll spend with your family. The difference between visiting your parents and living beside them is a bigger deal than most people think.

What Does the Visit Math Actually Add Up To?

Start with a nice normal amount of visits. Let's say you see your dad three days a week. Some weeks it is dinner, some weeks it is an errand that turns into a visit. Over a full year, that means you end up seeing him about 150 times in person.

Now put him fifty feet away in his own home on your property, and that's of course going to increase. No more driving or scheduling time out of your day. You drop off a plate on your way in from work, he walks over for coffee in the morning, the grandkids wander out to say hello. When you're that close, two short visits a day is a pretty good general estimate, and that works out to about 720 times a year.

Stretch that over a decade and the number grows quickly. Three visits a week comes to roughly 1,500 visits over ten years. Two a day comes to more than 8,000. Same parent, same ten years, more than 5x the amount of time, which is only possible because you live so close together.

Here's a chart we made so you can compare. The left column is the relationship most families already have with a parent who lives across town. The right column is what proximity does to that same relationship without anyone having to put in more effort or drive time.

There's a design reason those casual visits actually happen, and you should understand it before you make a decision. The reason is independence. A detached ADU gives someone their own entrance, their own kitchen, their own bathroom, and their own front door, and that independence is kinda the whole point. When a parent has their own space, stopping by doesn't feel like you're intruding or interrupting, because you don't have to walk through someone else's house. Compared to a spare bedroom inside the main house, where everyone is on top of one another, sharing hallways and bathrooms and such, it can become an irritant and you really feel the lack of privacy. We've done this enough to know that it's important to be separate, but close, so that the visits are always welcome on both sides. Proximity without independence can really wear on people after a while. Being close, but independent is what turns 150 visits into 720.

Won't We See Them Just as Much by Visiting?

This is a valid concern, and it deserves an honest answer. If you're already a close family, maybe you're wondering if building an ADU would even change things enough to justify the investment. But it changes the kind of interaction you have with them, and that's really important.

A visit across town is something you have to plan for, and you have to have the extra time for the drive. That naturally limits how often you can go see them, even in the closest families, because everyone is busy and life dictates how much time you have to spare more than it probably should. But when parents are right there on the same property it's no longer a chore or scheduling problem to go see them, so it just naturally happens much more often.

Dr. Amber Bartlett, a business psychologist who has also experienced this as a BuildX client with her own parents now beside her, described how it changed things for her. Being able to have coffee with her mom used to be one of her favorite things, she told us, but they would have to schedule it and work around her job and the drive. Now she can just text her mom and say she is coming over for coffee in the morning. That pretty much sums it up. Their relationship got even better without anyone having to put in extra effort, she no longer has to work around a busy schedule to spend a few minutes with her mom.

Is Proximity Actually Better for Everyone, or Just Convenient?

Convenience is usually the main upside to this. But there's more to it, and we've come to take that more seriously after the last few years.

When the pandemic separated families, it exposed how fragile the whole "we talk all the time" thing really is. When you can't reach the people you love, you learn quickly that phone calls are not the same as being with them in person. What that COVID time taught a lot of families is simple and difficult. When you're separated, you're on your own, and no one else is physically there when you need them. Being near your family is not a luxury for a lot of people, it's their safety net.

We are builders, not clinicians, so we rely quite a bit on what the professionals tell us. In Dr. Bartlett's professional opinion, family being near each other is not just a nice thing to have, it's healthier based on scientific evidence. We'll let her make that claim because she's the expert. What we can add is what it looks like in real life. On our projects, the payoff that surprises families most is not the parents at all. It's the grandkids.

Dr. Bartlett described her young son and what having the ADU next door did for him. He will announce that he is going to see Nana, and before she knows it he's out the door and on his way. He gets to see his Nana and Bubba whenever he wants. That really makes his childhood special and she wouldn't be able to give him that if they lived across town. She says it's one of the biggest reasons that being nearby benefits a family for an entire generation, not just a few years.

Is the Relationship Worth What the Build Costs?

Here's how the math works out. An ADU is one of the larger investments a family makes, and the cost is significant and paid up front. Compare that to the math of visits over many years. With an ADU you only pay once. When your parents live across town it becomes an expense that you have to figure into daily life for as long as they are with you.

We're not going to tell you that it's worth it for every family, because it's not. Most builders don't really talk about this, but we want to say it simply. Proximity can't fix a relationship with your parents that's already strained or difficult. Building them an ADU in the backyard won't solve that problem, and 720 obligated visits a year can be harder than 150 easy ones. The math only pays off when everybody really does want to be close to each other. Having more time together either makes a good relationship better or a difficult one even harder.

So the real question is not whether the numbers are significant because they are. You need to ask yourself if the relationship you have with your parents is one you want more of. If the answer is yes, then the math works in your favor and building the ADU is a great idea, because it's the one benefit you can actually count on. If the answer is no, then having your parents next to you isn't a good idea and honestly you should just keep your money.

What Would More Time Be Worth to Your Family?

The visits are the part you can't get back, and nobody had put a number on it before. Now you have the number. Three times a week or two times a day, 1,500 over a decade or more than 8,000 when they're right next door. If the relationship is one you want more of, the next step is not another spreadsheet. It is standing on your own property and seeing where the unit would go.
