How much do built-ins cost? A finish carpenter's honest breakdown

"What do built-ins cost?" is the first question I get, and the honest answer is that nobody can quote a cabinet run they haven't seen. A built-in isn't a catalog item — it's carpentry built to your wall, your ceiling, and your out-of-square corner. Two projects that look the same in a photo can bid hundreds of dollars apart because of what's hiding behind the doors and where the walls stopped being square. So instead of a number I can't honestly give, here's what actually drives the price on a built-in, and what you should expect to see in the quote.

Why there's no per-foot number for built-ins

Crown and baseboard get priced by the linear foot because they're a repeated profile running down a wall — measure the run, you're close. A built-in has no repeat. A wall of shaker cabinets with adjustable shelves is one kind of labor; add drawers on undermount slides, glass-front uppers, a scribed face to a plaster wall, and a built-up crown returning into the corner, and you've stacked four different trades into one piece. Each one carries its own material and its own hours. That's why a built-in gets bid per piece, off your actual drawings — not off a square-foot rule of thumb. For where the common trim pieces do have ballpark ranges, see our finish carpentry cost guide; a built-in sits outside that because it's assembly work, not a run of profile.

What actually drives the price

When I walk a built-in and put a number on it, these are the levers moving it — biggest first:

• Size and complexity. A floor-to-ceiling wall unit is more material and more hours than a single alcove of shelving. But height matters as much as width — a nine- or ten-foot run means working off staging and fitting a crown up where every gap shows.
• Paint-grade vs. stain-grade. The single biggest multiplier. Paint-grade lets me build in poplar and MDF and caulk a joint clean. Stain-grade means selected, grain-matched stock, tighter joinery, and no caulk to hide anything — every joint has to close on its own. (More in stain-grade vs. paint-grade trim.)
• Doors, drawers, and glass. Open shelving is the value end. Every door adds a slab, hinges, and six-way adjustment to set the reveal even; every drawer adds a box and slides; glass fronts add mullions and cost. The door and drawer count moves a built-in number more than the overall size does.
• Crown, face frames, and scribe. A built-in that dies into the ceiling with a built-up crown, returns cleanly at the corners, and scribes tight to an out-of-square wall is real finish carpentry. That fitting — not the box — is where the hours go.
• Wall and floor condition. Bowed drywall, a floor that runs downhill, a corner that's a couple degrees off square — all of it gets scribed and shimmed out so the piece looks factory-built. The worse the wall, the more hours to make it disappear.

Design isn't in our number — and that's on purpose

One thing to be clear about: Dunn Trim Co. is an install shop. We build and install built-ins from a plan — we don't design them. If you've got drawings or a designer's elevation, that's exactly what we bid from. If you don't yet, we'll route you to a design partner to nail down the layout, the door style, and the finish before anything gets priced. That keeps the quote honest — I'm pricing a defined piece, not guessing at a moving target — and it keeps you from paying for design churn inside a carpentry bid.

What you should expect to see in the quote

A built-in quote is only as good as it is readable. A vague one is where the surprises live. Here's what a real one spells out:

• The piece, defined. Dimensions, door style and overlay, drawer count, shelf type, and whether there's a crown or a scribed face — so we're both pricing the same built-in.
• Paint-grade or stain-grade, stated. This is the biggest lever, so it should never be assumed. The grade and species belong in writing.
• Supply vs. install, line by line. Are we building it, or setting a shop-supplied or homeowner-supplied box? An install-only number and a build-and-install number aren't the same money — the quote should say which. (See how we run a built-in install.)
• What's excluded. Paint and finish, electrical for lighting, countertop if there's a base cabinet — named as in or out so nothing falls between trades.
• An allowance where a selection isn't final. If the door hardware or glass isn't picked, a clear allowance, and what happens when the real number lands over or under it.

Where the money is well spent

Built-ins are one of the few finish upgrades that pull double duty — they add real storage and they're the thing buyers photograph. The spend that pays off is in the fit: the scribe to the wall, the even reveals on the doors, the crown that returns clean into the corner. That's the difference between something that reads as custom and something that reads as a bookshelf shoved against a wall.
