Should You Tour a Finished ADU Before You Build One?

Watch: Before You Spend a Dollar on an ADU, Watch This First

You have three or four floor plans open in your browser, but you can't seem to pick between them. On paper they're similar enough that the choice comes down to a hundred square feet and a wall. It's hard to commit to a home your mother, your daughter, or you will live in for the next twenty years just based on a picture of a floor plan.

My name is Buz Artiano, founder of BuildX. We've built dozens of ADUs all over Massachusetts, but most of our jobs have been on the South Shore and in Plymouth County. We handle everything for you, that means all of the design, permitting, and construction. So the same team that evaluates your septic, checks your lot coverage, and stands in front of your town's permitting board is the team that actually builds the ADU. That's exactly why we tell homeowners to go walk through a finished unit before they choose anything.

Charlie and Debbie Morse are BuildX clients. We are building their detached ADU in their own backyard for a family member who is moving in. Peg and Jim Duggan are BuildX clients in Rockland, where they have lived for 42 years, and we are building their ADU on their own property so they never have to leave the lot. Neither of those families picked us by looking at our website. Both of them walked a finished ADU on a weekend first, and both of them say that was the moment they decided to build.

Of course a builder is going to tell you to come see the homes he's built. But what matters more is that neither of these families made up their mind because of anything our people said to them on a tour. The Duggans made their decision on their own, we were not part of the conversation. That's the benefit of taking an actual tour of a finished home, whether it's one of ours or somebody else's.

Should You Pick Your ADU Plan Off the Website?

A pre-done plan is the best place to start, but that's not usually where you end up. The plans published on a builder's website are really just the beginning of a conversation. They tell you size, bedroom count, and where the bathroom and kitchen go. They can't tell you whether that kitchen is the size your family actually needs to cook in, or whether the bathroom feels like a closet once you shut the door.

The Morse household started the same place you are. As one of them put it:

If you have it narrowed down to 3 or 4 plans, but can't pick a winner, that is not necessarily indecision. That just means that the drawing doesn't tell you enough to make a decision. The Morses were in that exact spot, and then had everything solved in one weekend.

The Difference Between a Drawing and a Doorway

Standing inside a completed unit gives you the things a floor plan flattens out. You get a real life feel for how big the kitchen is and how big the bathroom is. You get to see the options that the homeowner picked like colors, cabinets, flooring, and countertops. It helps you get a feel for what you want in your own house, which is a whole different thing than looking at a flat piece of paper or a screen.

Here's why we do it this way. Almost every time, when a homeowner requests changes after going on a tour, it's just a simple dimensional change that they want. Maybe they want the kitchen island moved, or a bigger deck, or a wall scooted over a couple feet. We build from scratch, we don't build modules, which means we frame and build every piece of the house on your property, we aren't setting pre-built boxes on a foundation. If you want the ADU to be 21 feet, 2 and a half inches wide, we will build it 21 feet, 2 and a half inches wide. Cathedral ceilings, vaulted ceilings, a sunroom, a bigger deck, a garage. We can do it all. That flexibility is worth a lot before we draw and finalize plans. The opposite is true if you wait until the framing is up. A tour is what gives you the details you need so we can build to exactly our specs.

Who Should You Actually Talk To on a Tour?

You should always talk to the homeowner. Not the builder or their staff. A homeowner who is letting you tour the house they paid for has no reason to sell you on anything, and that's exactly why it's so worthwhile to talk to them.

Peg Duggan found us through a neighbor and then found answers for herself in somebody else's ADU. In her words:

Jim Duggan put it in six words: "That's what did it for us."

That Marshfield homeowner doesn't work for us. She was building an ADU for her daughter and she answered Peg's questions having nothing to gain. If you got a builder's name from someone in town, but you need more to go on than just a personal recommendation, that's exactly where Peg was at. That's why she went and toured a real ADU.

Six Things Worth Judging With Your Own Eyes

A tour is just a field trip unless you've got a good list with you. These six things are what most of our clients change their minds on after seeing them in person. We recommend that you bring the two or three plans you like and compare them to the room you are actually standing in.

• The kitchen, judge this by the way your family actually cooks
• The bathroom, see how it feels to turn around in and how much space there is
• The cabinets, look at the doors and drawers you will be using every day
• The flooring, make sure you're seeing it in the light the room will always get
• The countertops, is it a nice surface that you won't mind wiping down all the time
• The finishes another homeowner chose, see if they are something you would have picked

Write down what you would change while you're still there and can see everything in person. Making your changes during a tour costs nothing, but if you wait until framing, it costs time and money.

What Will You Still Have to Solve on Your Own Lot?

A finished unit tells you everything you need to know about the building, but it can't tell you anything about your specific lot. Your septic, your slope, your tree line, your driveway access, and where the sun lands in the afternoon are all unique to your property. We evaluate all of those things in person at your property, which is why a tour can never be a sales appointment. We have to see the property before we even know what's possible.

Our sequence starts with a Zoom meeting to see whether an ADU makes sense for you and your family, and we talk about budget in that meeting. A site visit comes next, and a proposal comes after that. The tour sits ahead of all three, which is the point. Walk the house while you owe nobody anything.

When Is It Too Early to Tour an ADU?

When your family has not settled the important questions, none of which have anything to do with the design of the building. Building an ADU ends up being about 70 percent family dynamics and only 30 percent about the actual building. If your family is not all on the same page about the whole project, don't spend money on plans or surveying until everyone is in agreement. There's a lot to discuss about money and inheritance, who is going to take care of who, and those need to be talked about and resolved within the family, not with your builder.

We would rather you skip the tour this month and have the family conversation instead. A weekend walkthrough does nothing for disagreement about who inherits what. It will only make everything much more expensive to untangle later.

We're also not the right builder for everyone, and a tour is the fastest way to find that out. If you want a factory-built unit dropped onto a foundation on a strict schedule, then you will see after a walk through that we are not the right company for you. Go tour other builders' finished work, too. If you can only get a builder to show you pictures and drawings, no finished product that may be a red flag.

What Should You Do Before You Sign Off on a Plan?

Narrow the website down to the two or three plans you like the best, then go tour one on a weekend. Talk to the person who owns the house, not the builder or whoever is hosting the tour. The Morses did it, the Duggans did it, and both families changed what they asked for afterward. Tour locations and dates shift as projects finish, so check the current schedule before you drive out.
