ADU Company in Upland, CA
Kitchen remodeling in Upland usually means working inside a 1950s-to-1970s stucco tract home where the original galley layout, single circuit wiring, and slab foundation dictate what’s possible before design even starts. We handle that reality every week. Guest House ADU Builders runs kitchen remodels, ADU construction, and bathroom renovations as one coordinated team, so the same crew that reconfigures your main house kitchen can also convert the detached garage or build the backyard unit. Call (833) 863-7015 to talk through your property.
Why Upland Homes Are Different
Upland’s housing stock skews heavily toward post-WWII through 1970s single-family tracts. Most homes in the 91784, 91785, and 91786 zip codes are one-story stucco on slab with detached or attached two-car garages. That matters because nearly every ADU project here is a garage conversion or a backyard infill on a lot that was platted decades ago, not a clean new-build on open land. The existing garage often has a slab that was poured thin, framing that predates current shear-wall requirements, and no insulation to speak of.
Climate is the second factor. Upland sits at the base of the San Gabriel Mountains where summer temperatures routinely cross 100 degrees and Santa Ana winds push embers and smoke downslope in the fall. An ADU or kitchen addition here needs serious attic and wall insulation, reflective or tile roofing, and glazing that does not turn the space into an oven by mid-afternoon. We also see mature citrus and shade trees on many older lots, and their root zones plus heritage-tree protections can determine where a backyard unit can actually sit. You plan around the trees first, then the foundation.
Our Main Upland Services
Two services dominate the calls we get from Upland homeowners: ADU construction and bathroom remodeling. Here’s what each one actually involves on the ground here.
ADU Builders in Upland
Most Upland ADUs start as detached garage conversions or backyard infill units on lots where the main house was built between 1950 and 1980. The work centers on bringing an existing structure up to current Title 24 energy and structural standards, which often means new insulation, upgraded framing connections, and a slab assessment before drywall ever goes in. Design review in older tree-lined tracts means neighbors notice and comment, so we front-load the elevations and setback details. ADU Builders in Upland covers the full scope, including prefab comparisons and permitting.
Bathroom Remodeling in Upland
Bathrooms in older Upland tract homes share the same DNA: compact footprints, cast-iron drain lines, and slab floors that make moving a toilet expensive if not planned early. We sequence bathroom work alongside ADU construction so one permit cycle, one crew, and one schedule cover both. If your main house bathroom needs work and you’re adding a unit out back, coordinating them saves real money on mobilization and design time. See Bathroom Remodeling in Upland for the details.

Kitchen Remodeling in Upland
Kitchen remodeling in Upland typically means opening up a closed-off 1960s or 1970s galley kitchen in a one-story stucco home, where the original layout was built for a single cook and the electrical panel may still be a 100-amp Zinsco or Federal Pacific unit that needs replacement before new appliances can pass inspection. The heat is a real factor too: a south- or west-facing kitchen in this climate needs window treatment and ventilation planning or the space becomes uncomfortable by late afternoon. We do this work as part of the same team that handles Kitchen Remodeling across the region, so ADU and main-house work never get handed between contractors.
Full Kitchen Gut and Reconfiguration
Signs you need it
The layout no longer works for how you cook, the cabinets are original to the 1960s or 1970s and falling apart, or you need to move walls and the home’s slab foundation means plumbing re-routes must be planned before demolition.
What it costs in Upland
A full kitchen gut and reconfiguration in Upland generally lands between $55,000 and $95,000 depending on wall removal, structural headers, and plumbing moves on slab.
How we do it
We open the walls, verify framing and electrical conditions, re-route plumbing and wiring on the slab, install new drywall and insulation, then set cabinets, counters, fixtures, and finishes in a single continuous sequence.
Cabinet Refacing and Countertop Replacement
Signs you need it
The cabinet boxes are solid but the doors and drawer fronts are worn, or the existing tile or laminate counters are dated and cracked.
What it costs in Upland
Cabinet refacing with new doors, hardware, and a quartz or solid-surface countertop typically runs $28,000 to $52,000 in Upland.
How we do it
We measure and build new door and drawer fronts, reface the existing boxes with matching veneer, swap hardware, then template and install the new counters with a tight, clean edge profile.
What Kitchen Remodeling Costs in Upland
| Item | Typical range in Upland |
|---|---|
| Full kitchen gut and reconfiguration | $55,000 – $95,000 |
| Cabinet refacing and countertop replacement | $28,000 – $52,000 |
| Kitchen update with new appliances and finishes | $35,000 – $70,000 |
Upland costs run slightly higher than flatland Inland Empire cities because older slab homes hide plumbing and electrical surprises, and mature trees sometimes complicate exterior venting and gas line runs. We write fixed, line-item quotes so the number you approve is the number you pay.
How long does a kitchen remodel take in Upland?
A full kitchen remodel here runs 6 to 10 weeks. A cabinet reface with new counters usually takes 3 to 4 weeks. We set the schedule before demo starts and hold it unless permit review adds time. Call (833) 863-7015 for a free estimate on your kitchen.
Will the price change once work starts?
No. We write fixed pricing with a line-item scope before you sign. The only change order is when you add scope, and we price it in writing before any work begins.
