You look at the drawing for your cabinets in your ADU kitchen and there's a rectangle on there that's supposed to be your fridge, but it's labeled with something that you've never even heard of. An ADU kitchen is smaller than the one you're used to, so you don't want to lose any space for food just because no one explained things to you properly.

My name is Buz Artiano, founder and CEO of BuildX. We've built dozens of ADUs in Massachusetts, most of them on the South Shore and in Plymouth County. Our team does everything for you including the design, the permits and the construction. We deal with septic issues, the limits for lot coverage, and the state by-right rules and we'll also help you plan your kitchen, including the type of refrigerator you're going to need.

Bianca Brummerloh has worked 11 years as an appliance expert at Crane Appliance on Cape Cod, and she told us "a lot of homeowners don't even know what that is" when she talks to them about how deep the counter is and what types of refrigerators there are. Builders and cabinet companies deal with it all the time, but homeowners do not. We think a refrigerator in a small kitchen is picked when the cabinets are drawn and then going to the showroom happens after that.

Which Refrigerator Actually Fits My ADU Kitchen?

You have to build the plan for your cabinets around the fridge if you want it to fit perfectly in your kitchen. When a builder or cabinet company draws out your plan, Bianca told us they will draw it with a counter-depth refrigerator. Unless you ask for something different, that's what the plans come with.

It's reasonable to go with a counter-depth fridge because a refrigerator that's only as deep as the counters doesn't protrude into the room like a standard size fridge would. The doors and handles still go out past the counters, especially with the doors open, so be sure and measure your kitchen space against that specific unit's depth with the doors open. What you're giving up is some extra space at the back of the fridge, you'll have less room behind the front row of shelves than you would with a regular sized fridge.

Built-in refrigerators are framed into the cabinetry, and the model built for panels will have a door panel that matches. If the person moving into your ADU cares more about storage than whether they lose a few inches of floor space, then a counter-depth or full-depth refrigerator isn't the best answer, but if the kitchen is open to the living area built-in and panel-ready work great.

What Do Counter-Depth, Built-In, and Panel-Ready Actually Mean?

When a client comes to Crane Appliance without already having a plan, Bianca will begin with teaching them some terms that everybody should know. Things like what a counter-depth refrigerator is, and what a built-in refrigerator is. The terms can overlap so it can get a bit confusing sometimes. Counter-depth and built-in both describe how the refrigerator sits in the kitchen, and built-in is a term that's used more widely though. Monogram brand, for instance, uses the term "built-in" for stainless, overlay, and fully integrated types of refrigerators. Overlay models have a vent and a door panel and integrated ones are fully covered in panels and they're also level. Panel-ready is just referring to what covers the doors, so both overlay and integrated refrigerators would be considered panel-ready and a stainless built-in wouldn't be.

Here's how these terms compare with each other for a compact ADU kitchen, based on our discussion with Crane Appliance and the standard definitions used throughout the appliance business. The table doesn't show dimensions or capacities, because those figures change by brand and model, and the only reliable number for your kitchen is the specification sheet for the exact unit drawn into your plan.

What Does Counter-Depth Give Me, and What Does It Take Away?

Cabinet designers usually prefer counter-depth refrigerators because of the bottom cabinetry that will be installed. Standard bottom kitchen cabinets are 24 inches deep, and the countertop hangs over them by about an inch. A counter-depth refrigerator is also 24" deep so it will match up with the edge of the counters. If you put a standard-depth refrigerator (30" to 36") into the same place it's going to stick out past the counters. In a compact ADU kitchen, you can't afford to lose that space.

So counter-depth will give you a refrigerator that doesn't stick out past the counters and cost you floor space. The doors and handles will still go past the counters, so check the depth with doors open and the door-swing clearance against the width of the aisle in your planned kitchen. What you lose is the back part of the refrigerator. Bianca told us that a big part of her work is explaining that to clients who come with a plan from the builders.

When you measure the trade in your own kitchen, you should ask for two specification sheets: the counter-depth model drawn into your plan, and a standard-depth model of the same width from the same brand. Then compare the total interior capacity in cubic feet and the shelf depth. That comparison will tell you exactly how much storage space the counter depth model will take away.

Is a Built-In or Fully Integrated Refrigerator Worth It in a Small Kitchen?

Bianca showed us a modern cabinet style on the Crane Appliance showroom floor and told us that an integrated, flush design, which is where the face of the refrigerator looks exactly like the cabinets and doesn't protrude into the kitchen space at all, is getting more and more popular. She said a lot of brands have left behind the traditional look, the Sub-Zero style with the compressor grille across the top and doors underneath. Luxury lines still sell stainless and overlay built-ins as well as the integrated models, so make sure you confirm which one is in your plan.

In an ADU, a fully integrated refrigerator will give you the most benefit when the kitchen shares space with the living room. A refrigerator that matches the cabinets exactly will keep the whole wall looking like nothing but a beautiful row of cabinets. But a built-in fridge goes into an opening that was created for its exact dimensions, so replacing it means finding a unit with the same dimensions or redoing the cabinets.

Bianca told us panel options are mostly in the luxury lines of refrigerators, while average brands tend to only have panels for dishwashers. And what's available is different depending on the brand and model of refrigerator you choose, so check that the exact unit you pick will work with a panel before the cabinet company builds everything into your spec.

Can I Keep Storage Flexible Without a Bigger Refrigerator?

One feature that's worth asking about in a small kitchen is the convertible drawer. Brendan Crane, vice president of Crane Appliance, talked about it with us. He said that four-door refrigerators now come in a lot of different sizes and many of them come with a drawer you can convert and use it as either a fridge or a freezer.

This matters because who lives in the ADU can change over time. A parent, a renter, and an adult child each use a refrigerator differently, and a drawer that switches between freezer and fresh food will work for each person with having to replace the appliance. The feature was new to us when Brendan described it, so ask before the model is decided on.

Do I Need Panel-Ready Appliances for My ADU Kitchen to Look Finished?

Panel-ready kitchens look good in a picture, so you'd expect a builder to encourage them. We don't. At Crane Appliance we admitted that a cabinet panel appliance looks great to us, but our eyes are still drawn to a kitchen where the appliance shows, because that's what we are used to seeing.

If the refrigerator is going to show, the finish is what decides the look. Bianca sees fingerprint-resistant finishes with the commodity brands, while the luxury lines are using traditional stainless steel. Color is coming back too. Brendan told us that KitchenAid is introducing a forest green called juniper. A visible appliance in a finish you like will make the refrigerator replaceable without new panels.

Panel-ready tends to work best when you want the refrigerator to disappear into the cabinets, you've got a large enough budget for appliances, and you don't plan on swapping in a cheaper unit later. If any one of those isn't true, it's better to just go with a counter-depth refrigerator in a nice finish for your ADU kitchen.

What Should I Ask Before I Approve the Cabinet Drawing?

When counter-depth is drawn in automatically that is a red flag to act on. The refrigerator class is determined the moment the cabinet plan is approved. Ask these questions while the plan is still a drawing:

• Which refrigerator class is put into the plan: counter-depth, standard-depth, built-in, or fully integrated?
• Which brand and model is the opening built for?
• How does the capacity of the interior compare with a standard-depth model of the same width?
• What is the model's depth with the doors open, and does it go out into the aisle?
• Does this exact model take a cabinet panel, and who is building it?
• Is a four-door model with a convertible drawer available in that width?

Bring those answers to the showroom, where you can see and touch your options. Once you know the opening, the class, and the capacity trade, the visit becomes a comparison of real possibilities.

Want to See a Finished ADU Kitchen Before Your Cabinets Are Drawn?

The refrigerator in your ADU is decided on at the cabinet drawing. If you understand the terms and questions to ask, you can make that decision on purpose. The next step is seeing a finished ADU kitchen in person.
