How do you build aging-in-place readiness into an ADU without it looking like a hospital, so an aging parent will accept it?

Watch: What Happens When Mom Can't Live Alone Anymore: ADUs, Aging Parents & Family Planning (Juli Ford)

You already know an ADU could keep your mom or dad close to you at home and out of an assisted living facility. But a lot of times the parents don't want to entertain the idea because they think it's going to look and feel like a hospital or medical facility. They're picturing grab bars by the toilet, a big ramp out front, and a bathroom that looks like it belongs in a rehab place. When mom and dad hear that, all they hear is that you think they're old and incapable, and the whole idea just sorta dies.

My name is Buz Artiano, founder of BuildX. We design and build ADUs all over Massachusetts, but most of our projects have been on the South Shore and in Plymouth County. In July 2024 we pulled the first detached-ADU permit ever issued in the town of Plymouth. Since then we've participated in over 400 planning meetings and done more than 300 site visits with families who are trying to figure out if an ADU is the right choice for them. We do absolutely everything, from design to permitting to construction. That means that we plan out all the things that make an ADU age with you from the design phase. We don't go back later and try to add things and tack things on and tear up your home. Everything is planned out from the very beginning.

When this is done right, the home doesn't look accessible. It looks normal, but the infrastructure is built in, inside the walls and floor plan where no one sees it until you need it. That's the whole thing, and it's purely a design decision you make once, at the very beginning, and the cost is very little. Here's how we build an ADU that's ready for a walker, a wheelchair, or a chairlift, without anything looking like a hospital when your parents move in.

How Do You Build In Aging-Readiness Without It Looking Medical?

The answer is simpler than you might think, and what's important is the order you do things in. Anything you do that changes the bones or structure of the house, like the framing, the width of a door, the size of the bathroom, the angle and width of the stairs, is almost free to build while the unit is in the construction phase. Adding those things later gets ugly and expensive. Anything that makes someone think of a medical facility, like visible grab bars, surface ramps, a shower bench that looks like it came from a hospital, makes it feel like less of a normal home. It's very cheap to add the accessibility features the day they're needed, your parents don't need to see it everyday before it's needed, reminding them of their age.

So we split the work up into two parts. We build in all the structural stuff while we're framing. We leave everything that you can see hidden until it's needed. The result is a place that looks like a normal, comfortable home on move-in day and later becomes a home your parent can stay in if they ever end up needing a walker, a wheelchair, or a chairlift. We do all this without it being a renovation project and without having to talk about the stuff that nobody wants to talk about.

Why Will Your Parent Resist Anything That Looks Medical?

A lot of builders don't even think about this, and it's why so many accessible homes that were built with good intentions remain unoccupied. People don't resist because there are accessibility features, it's more about them having to look at them and be reminded about their aging on a daily basis.

Aging-in-place specialist Juli Ford, who spent years helping seniors downsize, sat down with us on our podcast and summed it up. She said that a healthy 68-year-old touring a senior community doesn't want to see a grab bar next to the toilet. But it's not because the bar is ugly. It's because they are constantly being reminded of the day they will need it. Having to think about that can really take a toll and cause them to not want to live there. We see the same exact mindset in our own design meetings. The moment a floor plan looks like it was created for an elderly patient, the parent just wants to dig their heels in, and the adult child is stuck because they need a safe place for their parent, but the parent doesn't want to live in a place that feels "medical".

You can't fix this just by skipping the readiness step, you have to take away the visual reminder for them. Every feature that reminds them that they are aging gets put off until they have to have it. All the safety features and infrastructure for them is buried in the walls where it's not staring at them all the time. Your parent moves into a home that feels like a normal house, and you get the peace of mind that the safety features are pre-done inside the walls for whenever you need them.

Why Is the Bathroom So Big?

One of the most common questions we hear when a family first walks through one of our ADUs is why the bathroom is so big. It looks so big, almost oversized, next to the tiny bathrooms you find in small homes and apartments. But we do that on purpose, it's not a luxury, it's imperative to adding accessibility features you will need down the road.

A bathroom that's built big enough for a wheelchair or a walker will look like nothing more than a comfortable, roomy bathroom the day we build it. There's no equipment in it and nothing to trigger your parent when they look at it. But from day one there's plenty of room and clearance so that one day when a walker or a wheelchair is needed, the room won't need any renovation or moving of walls or any structural changes whatsoever.

The reason we make these decisions during the framing is because of in-wall blocking and when you can add it. Blocking is solid wood that goes between the wall studs behind the finished wall, and it's what a grab bar anchors in to. A grab bar that's screwed into the drywall without the blocking being in the wall already will just tear out when real weight is applied, making it incredibly unsafe for an elderly person. Adding blocking while the wall is still open, before insulation and drywall, costs almost nothing and you can't see it in any way. Adding it later means you have to tear into the walls, and then patch up and repaint everything. That's why so many families never do it and they just end up installing the grab bar into the drywall that will easily just rip out. We put the wood in the wall now so that years down the road all you have to do is screw in the bar with 2 screws and it's extremely strong and safe.

That basically sums up our whole thinking when it comes to this kind of stuff. Safety is the most important thing and the anchoring is built to actually hold weight. When it's built, it just looks like a nice big luxury bathroom.

How Wide Should the Doorways and Hallways Be?

Door width is the least noticeable accessibility feature in the whole home, and it's easy to do it wrong. A standard interior door in an older small-home plan can be as narrow as two feet six inches, which barely fits a walker, and a wheelchair is out of the question.

We build all the main doorways at three feet wide. On move-in day, a three-foot door doesn't look medical at all. It just looks like a wide, well-made door in a comfortable home. Nobody tours the unit and thinks of accessibility when they see a big door. They think it makes the place feel more open. But it's the difference between someone being able to move freely through their own home later rather than being stuck in one or two rooms because of a wheelchair. The main hallway is also designed and built wide enough to turn and pass, disguised as a luxury, not an accessibility feature.

This is why making the infrastructure invisible is so much better than having a checklist of features. A checklist tells you to install a wide door. The design approach makes the wide door feel like a luxury choice, so the person living there never has to feel like it's about a wheelchair or a walker.

Can a Staircase Be Ready for a Chairlift Without Showing It?

If the ADU has a second floor, the stairs are where families either plan ahead or get stuck. A chairlift needs a certain amount of space. The rail and the seat can be wide, and if the stairs are only the standard minimum width, there's no way to widen it later without tearing out and reconstructing the entire thing.

So when a unit has a staircase and the family is planning for a parent to age in it, we build the staircase wider than the standard minimum three feet. We do it at about four feet wide. When the build is done, it just looks like a grand, comfortable staircase. It doesn't feel like a chairlift track at all. We also build in a landing, which is a flat transition spot at the top where a person can step off safely from a chair lift. We make sure the space is there and ready, the equipment comes in only when needed.

The tradeoff is that a wider staircase takes up more space, and space is very limited in an ADU. That's a legitimate downside, and that's why we walk through the decision with each family based on whether a parent is actually going to live on the upper floor or not. If they never will, we don't use up the extra space because it's not necessary.

Should You Build the ADU Detached Now and Connect It Later?

For a lot of people, the right answer today is usually a detached unit, which is a separate small building in the backyard, even when the long-term plan may be to have your parent under the same roof as you. You can plan for both outcomes.

When we design a detached ADU for a family who wants to plan for aging, we position it close to the main house, usually about ten to twelve feet away, and we set it up so it can be joined later by a breezeway. The breezeway doesn't have to be built now. A lot of times it can start as just a simple deck that goes between the two homes, with no separate foundation. Then we just turn it into an enclosed, weather-protected walkway whenever the family is ready. Detached for now, and attached later when it needs to be.

Building a detached unit is actually only possible now because Massachusetts passed that law that allows one ADU by right on most single-family lots under the Affordable Homes Act. It means you don't need a special permit to build it, though local building, health, and dimensional requirements still apply and still have to be met at the town level. All of the specific requirements are at mass.gov.

Does Every ADU for a Parent Need All of This?

No. And any builder who tells you that every ADU has to have all these features is selling you square footage and hardware you probably don't need.

We build these things into our ADUs as a default because most of our clients are planning for a parent to stay permanently as they age, and the cost to put in all the infrastructure during construction is so low that skipping it just doesn't make sense. But the right package depends on the family and their situation and their plans. If your parent will only ever live on a single floor, there's no reason to widen a staircase for a future chairlift. If everyone agrees the two homes will never connect, you can build a clean detached unit and not even do the breezeway prep. If a parent is already using a walker or wheelchair, some of the invisible features we talked about have to be installed immediately, and we design them in that way.

The point of future-proofing is not to install everything. It's about making decisions early on about where things will likely go, and then build only what is needed in a way your parent will be ok with.

How to Decide Which Future-Proofing Your ADU Actually Needs

The families who accept an aging-in-place ADU are almost never the ones who were handed a list of medical features. They're the ones who were shown a comfortable, normal home and told, quietly, that the bones are already there for whatever needs there may be in the future. Your job at this stage is not to plan out and memorize all the accessibility features. You're really just trying to answer two questions that decide the whole design. Is a parent likely to live here for the long term, and if so, on one floor or two? Answer those honestly with your family, and the accessibility package will almost design itself.
