Can I Build an ADU for My Special Needs Child? (One Family's Story)

Watch: Why This Family Built an ADU for Their Autistic Son | Plymouth's 1st ADU

If you are the parent of an adult child with autism, Down syndrome, or another developmental disability, we know you lose sleep at night wondering what happens when you aren't here to take care of them anymore? Group homes just don't feel right and their waiting lists are years long sometimes. The options you have so far are not going to give your child the kind of life you want them to have. You don't want them to live in a facility, you want them to live in a home.

My name is Buz Artiano, and I am the founder of BuildX. We've built dozens of ADU projects across Massachusetts, mostly around the South Shore and Plymouth County areas. We are the only team you need, we handle design, permitting, and construction. So we see every phase of a project from the first site visit up until you move in. We deal with septic constraints, zoning issues, and the state's new ADU laws under the Affordable Homes Act. I started BuildX because I believe families deserve a builder who's first job is to listen, and second is to build. When Pam and John Myette came to us with their situation, we understood immediately that this was not just a construction project. This was about their son's future.

Pam and John Myette are BuildX clients. We built their 900-square-foot, two-bedroom detached ADU at 72 Jordan Road in Plymouth for their son William, a 26-year-old nonverbal autistic adult. It was Plymouth's first ADU, which we finished before the statewide Affordable Homes Act took effect, so we built it under Plymouth's local regulations. The second bedroom was actually designed for a caregiver who would either live on-site or stay overnight sometimes to help take care of William.

Of course we love to share stories from families who had a great experience with us, but we're sharing the Myettes' story in particular because they had the same questions you do and they were faced with the same limited options, but we found an answer that was finally able to give them some real peace. Their story and their perspective is more useful to you than anything we could say about ourselves.

Can You Really Build an ADU for a Special Needs Family Member?

Yes. If you own a single-family home in Massachusetts with enough land to meet your town's setback and lot coverage requirements, you can definitely build an ADU for your special needs adult child right there next to the main house. Under the state's by-right ADU regulations, most Massachusetts homeowners can add one ADU to their property without a special permit. If you'd like, you can see the full requirements at mass.gov.

For the Myettes, it was pretty obvious to them which direction they needed to go. John said very plainly that their son Billy is a 25-year-old autistic adult, and they needed to find a place for him to live long-term. The options they had were basically to send him to a group home or build something themselves. A group home was never going to work. Billy wouldn't be able to adapt to that environment, and Pam and John knew it.

Pam said something that every parent in this situation will understand: "We are forever parents. We need to care for this child for his entire life." That's not a statement about obligation, it's a statement about love, and about knowing that the planning never stops.

Why Did the Myettes Choose an ADU Over a Group Home?

John was direct about it. The only options they had were sending him to a group home, which Billy would never adapt to, or an independent home where he could be close to family. They wanted Billy to have as much independence as he could, but he still needs daily care and support. It's almost impossible to find both in our current system. Group homes are made to help support the facility, not the individual person who has to live there. Waiting lists for supported living programs can be years long. But as the time goes on, you know your child is aging without a stable plan for the future.

The ADU solved both problems at once. Billy lives on the same property as his parents, in his own home, with his own space. The second bedroom was designed and built for a caregiver who can either live there full time or stay overnight when needed. When John and Pam can't care for Billy's daily needs anymore, their oldest son will move to the property and oversee Billy's care. So everybody, both generations, are able to live together on one lot at 72 Jordan Road.

If you're up against this same type of situation right now and you're trying to figure out whether to put your child on a group home waiting list or find another option, the Myettes were in the same position. They chose to build an ADU, and they're so happy they did.

What Does It Take to Build a Special Needs ADU?

The Myettes' ADU is a 900-square-foot, two-bedroom detached unit. Plymouth's size limit at the time was 900 square feet, and we designed the layout to maximize every inch of that. The unit includes a master bedroom that fits a king-size bed and a separate bedroom for a caregiver. It also has a large bathroom with an oversized shower and built-in storage, and common living space with high ceilings and large windows.

Pam was pleasantly surprised, she said the design was life-changing! It has nine-foot ceilings and oversized windows that make 900 square feet feel like a full-size home, not a secondary house. She even said she loves the ADU more than her own house.

We designed the Myette's ADU with nine-foot ceilings and rear-facing sliders specifically because Billy spends most of his time inside. When someone lives full-time in a 900-square-foot space, every design decision becomes huge. Ceiling height, window placement, natural light orientation, and bathroom accessibility are very important decisions that determine whether the space feels like a home or feels like a room. We've built enough of these to know that the families who are happiest one year later are the ones whose ADU was designed around how their family member actually lives, they didn't use some generic floorplan.

The construction part went really fast. John said they broke ground in early October and were targeting a Christmas move-in. The actual build took 8 to 10 weeks, which was exactly what we wanted. John's friends who build houses couldn't believe it was done in three months. The reason we can do that is because BuildX handles all design, permitting, and construction. There's no gap between the architect finishing and the builder starting. One job just flows right into the next one.

Is There Financial Help Available for Special Needs ADU Families?

Pam told us that as a parent of a special needs child, their family was eligible for a $50,000 grant, and that Buz handled all the paperwork for them as well. She says that every parent of a special needs child should look into it.

Pam is calling this a grant because that's how it felt to her family. The program she is actually referring to is the Massachusetts Home Modification Loan Program (HMLP), which gives you 0 percent interest deferred loans of up to $50,000 for accessibility modifications to keep a family member in the least restrictive living environment. "Deferred" just means that you have no monthly payments while you live in the home. Program details and current eligibility requirements are available at mass.gov.

Whether the program available to your family is a grant, a deferred loan, or another form of assistance, Pam was just making the point that financial help exists, a lot of people just don't know about it, and a builder who has been through the process before can help you find it. Pam was pleased to say "Buz does all the paperwork. He handles everything."

Is an ADU the Right Answer for Every Special Needs Family?

No. Building a $250,000 to $350,000 structure on your property is a huge financial commitment. If your child needs 24 hour medical supervision that's more than what a live-in caregiver can provide, a residential care facility with licensed medical staff might be the only safe choice. If your lot can't support a second house because of septic limitations, setback constraints, or lot coverage restrictions, building an ADU might not be possible no matter how badly you want it to work.

But we also know that some families would be better off with other housing models like shared living arrangements, supported apartments, or family-funded residential programs. BuildX builds ADUs, that's all we do. If an ADU is the right fit for your family's situation, we will absolutely help you make it happen. But if it's not, we would rather tell you that on the first phone call than take your money for something that does not serve your child.

What Did the Myettes Say One Year Later?

One year after moving Billy into his ADU, Pam and John recorded a follow-up. It was so great just to hear the relief in their voices.
