ADU Company in Pomona, CA
Kitchen remodeling in Pomona means working with 1940s – 1970s tract homes where the original footprint was built for a different era of cooking, and where the inland heat puts real strain on ventilation and cooling. Sunstone ADU Builders handles both the ADU structure and the interior finish work under one contract, so the kitchen inside your new unit gets the same attention as the shell. Call (855) 949-1913 to talk through your project.
Why Pomona Homes Are Different
Pomona’s core neighborhoods, especially the 91766 and 91767 blocks radiating out from the historic downtown, are dominated by single-story stucco-and-wood-frame worker cottages and tract homes built between the 1940s and 1970s. These houses share a pattern that shapes almost every ADU project we take on here: deep backyards, rear detached garages with alley access, and original electrical panels and clay or cast-iron sewer laterals that are now past their useful life. In practice, that means the ADU conversation in Pomona rarely starts with design. It starts with a service upgrade, a lateral inspection, and a layout decision driven by how wide the alley actually is.
The climate adds another layer. Pomona sits in the eastern San Gabriel Valley, far enough inland that summer highs regularly push into the 90s and 100s with little coastal relief. An ADU built to mild-coastal assumptions will underperform here. We size cooling loads for real inland heat, shade west-facing walls, and specify insulated roofs. Winter nights dip cold enough for frost, and the Santa Ana wind events that sweep through the dry foothills make fire-resistant detailing a practical choice on edge-of-town lots. James Hardie fiber cement siding, which we specify on most exterior packages, answers both the heat and the wind exposure better than standard wood lap.
The other thing that makes Pomona different is who the ADU is for. A large share of demand here is multi-generational, not luxury rental. We hear the same story from homeowners across 91766, 91767, and 91768: an adult child who cannot find an affordable place closer to LA, or aging parents who want to stay near family without sharing a hallway. That changes the design conversation. Kitchen layouts get planned around daily cooking, not tenant turnover. Bathroom finishes get specified for aging-in-place usability. The unit has to feel like a real home, because in Pomona it usually is one.
Our Main Pomona Services
Most Pomona homeowners reach out to us for one of two reasons: they want a full ADU built on their lot, or they want a bathroom brought up to standard as part of a larger ADU or primary-home project. Here is what each looks like on the ground in Pomona.
ADU Builders in Pomona
Building an ADU in Pomona means working with the alley-loaded lots and older utility infrastructure that define the city’s housing stock. We assess your garage, your sewer lateral, your panel capacity, and your access before we recommend a path. On many Pomona lots, a garage conversion makes sense because the sewer and electrical are already nearby. On others, the alley width favors a new detached build. We are authorized builders for prefab brands including Abodu, Cover, Dvele, Mighty Buildings, and Plant Prefab, and we also build traditional stick-framed units. The full picture is on our dedicated page: ADU Builders in Pomona.
Bathroom Remodeling in Pomona
Bathroom work in Pomona’s older homes often means opening up walls and finding what is behind them: galvanized supply lines, deteriorated cast-iron drain sections, or framing that has shifted over six or seven decades. We scope the rough-in work at the same time as the finish work, so you are not hiring a plumber separately and then waiting on a tile contractor. Whether the bathroom is inside a new ADU or part of a companion remodel on the primary residence, our in-house team handles it under the same contract as the structure. See Bathroom Remodeling in Pomona for the full breakdown of what this service covers.

Kitchen Remodeling in Pomona
A kitchen remodel in Pomona usually starts with a house built before modern ventilation, insulation, and appliance loads were standard, so the work is about more than cabinets and counters. It is about correcting airflow, upgrading electrical for real cooking loads, and making the room comfortable through a summer that pushes past 100 degrees. Because we build ADUs as a specialty, our kitchen work is naturally scoped to the compact, efficient spaces those projects demand. Whether the kitchen is inside a new ADU or a companion remodel on the main house, the goal is the same: a room that works hard and feels finished. For a deeper look at how we approach the full scope of Kitchen Remodeling, see our service hub.
Full ADU Kitchen Build-Out
Signs you need it
You have a finished ADU shell with plumbing stubbed in and electrical roughed, but no counters, cabinets, or cooking capacity yet.
What it costs in Pomona
For a compact ADU kitchen, plan on $18,000 – $32,000 depending on cabinet grade, appliance package, and whether the plumbing rough-in needs moving.
How we do it
We finalize the layout against the as-built rough-in, set cabinets and counters, install the sink and fixtures, run the appliance circuits, and finish with backsplash and trim.
Primary-Home Kitchen Remodel
Signs you need it
Your kitchen still functions on the original 1950s or 1960s layout, with limited counter space, no ventilation to the outside, and electrical that cannot support a modern range.
What it costs in Pomona
Most full primary-home kitchen remodels in Pomona land between $32,000 and $58,000, driven by the scope of electrical and ducting upgrades on older tracts.
How we do it
We demo to the studs on the working walls, upgrade circuits and ducting, rebuild the layout, install cabinetry and stone, and finish with appliances and trim.
What Kitchen Remodeling Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Compact ADU kitchen build-out | $18,000 – $32,000 |
| Primary-home full kitchen remodel | $32,000 – $58,000 |
| Cabinet refacing with new counters | $7,000 – $14,000 |
How long does a kitchen remodel take in Pomona?
A compact ADU kitchen typically takes 3 – 5 weeks from start to finish. A full primary-home kitchen remodel usually runs 6 – 9 weeks. Pomona’s summer heat rarely delays interior work, but permit review times vary by season. Call (855) 949-1913 for a schedule estimate tied to your scope.
Will the price change once work starts?
No, not from us. We write fixed-price contracts based on a thorough inspection before demo starts. In Pomona’s older homes, the only wildcard is what is behind the walls, so we inspect and price accordingly up front. Call (855) 949-1913 for an exact quote.

What pushes ADU pricing up in Pomona is almost always the same pairing: an aged electrical panel that needs a service upgrade, and a clay or cast-iron sewer lateral that has to be replaced or sleeved before the unit can be permitted. The good news is we find these during the site assessment, so the price you see is the price we build to. No change orders after framing starts.

— Reggie Ellison"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Doug Padgett
