Phoenix homeowners are building more accessory dwelling units than almost anywhere in the country — and most of those ADU kitchens are tiny. A 400-square-foot casita gives you maybe 6 to 10 linear feet of cabinet, and every single one of those inches is working overtime. No one designs an ADU kitchen with deep, dark base cabinets full of unreachable pots and cans. They just build a small kitchen, and the storage problems show up the first week someone lives in it.
The good news: you don’t need a bigger kitchen. You need the cabinets you already have to actually work. That’s exactly what custom pull-out shelves are for — and small, tight ADU kitchens are where they make the most sense. Explore the full lineup in our pull-out shelves guide.
Why ADU Kitchens Are Where Pull-Out Shelves Earn Their Keep
In a full-sized kitchen, a bad cabinet is an annoyance. In an ADU kitchen, it’s the difference between the space being livable and a permanent pain. There’s no second pantry to overflow into, no island to build over, no spare wall to add storage to. The cabinet you have is the storage you get — so the question is whether you can actually use it.
Most ADU base cabinets are exactly the same depth as a standard kitchen cabinet: 24 to 25 inches deep. That means everything that isn’t on the front 8 inches is back there in the dark. In a full-size kitchen you compensate with drawer space and pantries. In a small ADU kitchen, you just dig. Every day. For coffee, for the cooking oil, for the canned goods, for the little appliances that end up living in a cabinet because there’s no counter space for them.
A pull-out shelf changes the cabinet from a “reach in and hope” situation into a drawer-like system where the whole contents come to you at standing height. No kneeling, no elbowing your way past the thing in front.
The Typical Phoenix ADU Kitchen: Small Boxes, Big Gaps
Almost every casita we’ve worked on in the Valley shares the same layout DNA: a compact L-shaped or straight-run kitchen, standard-depth base cabinets, a small range, a compact sink cabinet, and one or two narrow cabinets wedged between appliances. Those narrow boxes are usually where the storage dies. Too narrow for a lazy susan, too deep for anything useful, and too inconvenient to bother opening twice a day.
Here’s what tends to end up back there:
- Canned goods and dry staples that no one finds until they go stale
- Oil, vinegar, and the spice jars that migrated off the counter
- Small appliances (toaster, kettle, stand mixer) with nowhere else to live
- Backup pantry goods and holiday serving pieces
Each of those is a perfect candidate for a pull-out shelf. The narrow cabinet between the fridge and the range becomes a fully usable pantry slot instead of a lost corner.
What to Upgrade First in a Small Kitchen
When cabinet real estate is scarce, you don’t need everything. You need the right pull-outs in the right places. In an ADU kitchen, we usually prioritize in this order:
1. The sink cabinet
Under-sink storage is the worst cabinet in most kitchens — plumbing splits the space in half and nothing fits. A custom pull-out built around the pipe makes that cabinet usable for the small bottles, sponges, and backup supplies that live under every sink.
2. The narrow cabinet between appliances
That 12-inch box next to the oven is a natural home for a slim pull-out shelf. Spices, oils, a cutting board, the things you use daily and shouldn’t have to dig for.
3. The deep base cabinets
These are the biggest wins. A 24-inch-deep base cabinet with a full-extension pull-out becomes the primary storage for pots, cans, and bulk goods. In a small kitchen, this is where the daily cooking stuff lives.
4. Upper cabinets — selectively
In a compact kitchen, upper cabinets are usually the least-used storage because they’re awkward and heavy. A roll-out shelf for dishes and glasses turns the top shelf from “stuff we never touch” into real storage. We’d rather do two high-value upper pull-outs than fill the whole row.
Building It Right: What Actually Matters in a Small Kitchen
Small spaces punish cheap hardware more than big kitchens do. When you’ve got 8 feet of cabinet total, every pull-out has to be smooth and hold weight every single day. That’s why we build our shelves with full-extension, ball-bearing slides rated for 100 pounds, in hardwood that shrugs off Arizona heat and years of daily use.
One more thing that matters in an ADU: the shelves are built to the exact width and depth of your cabinet. Off-the-shelf organizers fit roughly. A custom pull-out fits like it came with the house — no shims, no gaps, no wobble. And because nothing changes about your cabinet boxes or doors, the install is clean and usually done in a single visit.
What It Costs (and Why It’s Cheaper Than You Think)
A typical project of ten custom pull-outs, built to fit and professionally installed, starts around $999. An ADU kitchen usually needs far fewer than ten — a smart ADU project might be three to six targeted pull-outs, which keeps the investment well under a full cabinet remodel. No new cabinets, no demolition, no permit. Just better storage in the space you already built.
For anyone building an ADU from scratch, the smarter play is to plan the pull-outs with the cabinet contractor from day one. We coordinate directly with builders and cabinet makers so the shelves arrive ready to install when the cabinets do.
