KraftMaid Home Additions & ADU Nationwide

KraftMaid Home Additions & ADU: The Redwood City Owner’s Guide

KraftMaid cabinet systems in Redwood City home additions and ADUs typically run $45,000-$130,000 installed, depending on whether you’re extending an existing kitchen into a new great room or building a standalone accessory dwelling unit with full cooking facilities. We stock and install KraftMaid-compatible cabinet configurations, hardware, and finishing systems for both attached home additions and detached ADU projects across the Peninsula. Most KraftMaid orders for Redwood City properties arrive within 3-4 weeks from the Ohio factory, with rush options available for time-sensitive permits.

Most Redwood City owners discover their KraftMaid system needs attention during the planning phase, not after installation. A failed or mismatched cabinet specification - wrong depth for an ADU’s compact footprint, incompatible door style for a historic district overlay, or a discontinued finish that no longer matches the main house - kills permit approvals and delays framing. In the Stambaugh-Heller neighborhood, we’ve seen owners order standard 24-inch base depths only to learn their ADU’s plumbing chase demands 21-inch customs. The symptom is usually a stop-work order, not a broken hinge.

Which KraftMaid Models This Applies To

KraftMaid organizes its product lines by construction type and price tier, and the right choice for a Redwood City addition or ADU depends on permit requirements and how the space connects to your main residence.

All-Plywood Construction (APC) is what we specify for most ADUs and additions in Redwood City. The box is 3/8-inch plywood, not particleboard, which matters in the Peninsula’s marine climate where winter humidity swings hit 30-plus points between October and April. APC carries a limited lifetime warranty and accepts any KraftMaid door style.

Vantage (particleboard core) is factory-direct only and costs less, but we don’t recommend it for ADUs. The moisture resistance isn’t there, and Redwood City’s proximity to the bay means fog-layer condensation in unconditioned spaces during construction.

Door style compatibility: Most KraftMaid door styles work across both construction types, but the Square Recessed Panel and Arch Raised Panel lines are what we see specified for craftsman-era homes in the Mt. Carmel and Friendly Acres areas. If your main house runs Canvas or Dove White painted finishes, the ADU must match exactly - KraftMaid’s painted whites shifted slightly in 2019, and the old formula is gone. We keep sample chips from both eras on our truck.

To identify your existing KraftMaid cabinets, check the hinge cup bore: a 35mm cup with two 8mm mounting holes at 48mm centers is standard post-2000. The interior label, usually on the back of a drawer front or inside a wall cabinet, lists a six-digit model code, finish number, and plant code (MX for Middlefield, Ohio). Bring that label or a photo to your estimate - we cross-reference it against KraftMaid’s active and discontinued database before quoting.

Signs Your KraftMaid Home Additions & ADU Is Failing

• Permit rejection due to finish mismatch. Redwood City’s planning department requires visual consistency between primary dwellings and ADUs in historic overlay districts. If your existing KraftMaid cabinets are a discontinued finish like Vintage Onyx or pre-2019 Dove White, the city may flag the difference. We spot this during pre-application review and source close matches from KraftMaid’s current line or specify complementary contrast finishes that satisfy code.
• Drawer box delamination in unconditioned ADUs. Particleboard drawer sides swell at the dovetail joints when humidity stays above 70 percent, which happens in Redwood City ADUs during the rainy season before HVAC is operational. The drawer binds, then the bottom panel drops out. We specify all-plywood drawer boxes with dovetail joinery for ADU work - it’s a $200-$400 upcharge per cabinet that prevents a $2,000 replacement two years later.
• Soft-close hinge failure after 18-24 months. KraftMaid’s standard Blumotion hinges are rated for 80,000 cycles, but salt air from the bay accelerates corrosion on the hydraulic cylinder. In Redwood City properties west of El Camino Real, we see premature failure compared to inland Belmont or San Carlos. The symptom is a slam or a squeak, not a complete separation. We stock replacement Blum 71B3550 hinges and can swap a full kitchen’s worth in a morning.
• Wall cabinet sag in long-span additions. KraftMaid’s standard 30-inch wall cabinet is built for 16-inch stud spacing. In open-concept additions where designers spec 36-inch or 42-inch widths for visual impact, the back panel flexes if the installer didn’t add blocking. The doors go out of square and the shelf pins pop loose. We check for proper blocking during rough inspection and upgrade to reinforced back panels on spans over 32 inches.
• Corner cabinet blind reach hardware binding. The LeMans or Magic Corner pull-out systems in KraftMaid’s base corner units use polymer trays that warp slightly in the first summer of direct sun exposure. In south-facing Redwood City additions, this shows up as a tray that doesn’t fully retract or a support post that clicks. We stock replacement trays and can convert problematic corners to lazy Susan or diagonal wall cabinet configurations during the design phase.

Replacement Cost & What’s Included

Home additions and ADUs using KraftMaid cabinets in Redwood City fall into the $45,000-$130,000 range for the full project, with cabinet packages typically representing 25-35 percent of that total. A standalone ADU kitchen with 12-16 KraftMaid base and wall cabinets, island, and pantry runs $22,000-$45,000 for cabinets alone; an attached addition extending an existing kitchen runs $14,000-$28,000 for the incremental cabinetry.

What drives the range:

• Construction type: All-Plywood Construction adds 15-20 percent over Vantage particleboard.
• Door style and finish: Painted finishes cost more than stained; glazed and distressed treatments add 25-35 percent.
• Customization: Non-standard depths for compact ADUs, appliance panels for integrated refrigeration, and modified heights for eight-foot ceilings in new construction.
• Hardware tier: Standard Blumotion versus upgraded Servo-Drive electric opening.

DIY or Call Us?

There’s safe checking, and then there’s work that needs a crew.

What you can verify yourself: confirm your existing KraftMaid model code from the interior label, measure your available cabinet run (width, depth, height to ceiling), and photograph any damage or wear patterns. Check Redwood City’s ADU handbook online for finish requirements in your zoning district - the city publishes this, and it’s free.

Where DIY goes wrong: cabinet installation demands laser-level precision - 1/8 inch out of level across a ten-foot run and your countertops won’t seat. In Redwood City’s older neighborhoods like Stambaugh-Heller, walls are not square and floors have settled; we come in with scribe tools, filler strips, and the experience of leveling 4,000-plus kitchens. Wall cabinet mounting into uncertain stud locations is genuinely dangerous without proper blocking and a second set of hands. We’ve been called to jobs where a homeowner’s self-installed 36-inch wall cabinet pulled out of drywall anchors - no injuries, but $800 in cabinet and wall repair.

Measure twice, document once, build it so it doesn’t come back. That’s how Grant Rowan runs every crew.
