Dvele ADU in Westminster, CA | Sunstone ADU Builders

We’re Sunstone ADU Builders, an independent Dvele service provider working across 92683, 92684, and 92685. The thing that separates our Westminster work from anywhere else: we know the 92683 streets where a crane pick for a Dvele module has to thread between a detached garage and a mature citrus tree.

Why Westminster Residents Choose Us for Dvele Service
Most builders in Westminster only meet a Dvele module the day it shows up on a flatbed. We’ve installed and serviced Dvele detached units, studio and one-bed configurations, two-bed modules, and above-garage setups across Orange County — including Garden Grove Dvele service — so the quirks don’t surprise us. We know how the steel-frame shell handles, where the utility stubs land, and how the panelized sections go together on a Westminster backyard that wasn’t designed for modular construction.
Nate Holloway, our owner, learned residential construction through the building trades program at Santiago Canyon College and spent nearly two decades on additions and garage conversions across Orange County’s hillside neighborhoods. He’s spent the last several years focused only on ADUs, which means he’s seen every way a Westminster lot can fight a prefab module and knows how to resolve it before the crane shows up. That experience matters when your 1950s tract home has a narrow side yard and one usable backyard corner.
We’re also a full-service ADU builder: prefab installation, modular ADU placement, panel upgrades, and the kitchen and bath finishing that makes a unit move-in ready. One contractor, start to finish. For details on our broader Dvele support, see our Dvele sales & service page.
Common Dvele ADU Problems We Solve in Westminster
- Crane and setback conflicts on narrow lots. Dvele modules ship in fixed-width sections. On 92683 streets with one-sided driveway access and a detached garage sitting between the street and the backyard, the pick point often falls short of where families actually want the unit. We survey the lot, confirm clearance and lot-coverage limits, and lock the set-down plan before the module is fabricated.
- Undersized electrical service. Westminster’s 1950s – 1970s tract homes frequently run 100-amp or smaller panels. A Dvele all-electric module with heat-pump HVAC, induction cooking, and on-demand water heating overloads that immediately. We handle the panel upgrade and new drop as part of the install, because factory drawings don’t account for it.
- Marine-layer moisture and flat-roof drainage. Dvele’s low-slope roof panels need verified slope and scupper placement. In Westminster’s persistent coastal humidity and occasional winter rain, poor drainage shows up as ponding and edge-seam staining within the first season. We check slope before the unit is set, not after water finds the seam.
- Foundation and grade transitions on old lots. Dvele’s steel-frame modules want a level, engineered foundation. Older Westminster backyards often have settled slabs, leftover garage footings, and root heave from citrus or avocado trees. Mismatched bearing surfaces telegraph as door and panel misalignment. We solve the foundation before the module lands.
- Rear-corner siting behind the garage. The one usable backyard corner on many 92683 lots is behind the detached garage, squeezed against a rear setback. That’s exactly where families want the ADU, and exactly where a crane has the hardest time reaching. We orient the module and stage the pick from the driveway side, then work with Dvele’s team to adjust set-points without compromising the design.
Dvele Service in Westminster: What Local Conditions Mean for Your Equipment
Here’s the thing about Westminster that a generic Dvele installer won’t catch: the 92683 core was platted with one-sided driveway access and narrow concrete side yards, so a Dvele module’s crane pick and set-down have to happen from the alley or driveway side. That means the rear corner behind the existing detached garage, exactly where families want the ADU, is usually the hardest place on the lot to land a factory module. The crane can’t reach over the house from the front because the side yard is too tight. It can’t come from the back because there’s no alley on most of these blocks. So the pick comes from the driveway side, and that changes everything: module orientation, set-down sequencing, where the foundation goes, and whether that mature lemon tree stays or goes. We resolve that before the module leaves the factory, because once the steel is cut, your options shrink to zero. This is the single biggest difference between a Westminster Dvele install and one in a newer Orange County subdivision with a 40-foot side street and a wide-open backyard.
On a block off Bolsa Avenue in 92683, a multigenerational family wanted a Dvele one-bed module in the rear corner behind their detached one-car garage. The mature lemon tree and the single-side driveway ruled out a straight crane pick. Our crew surveyed the lot, confirmed clearance and lot-coverage limits, and worked with the Dvele team to orient the module and stage the pick from the driveway side. We then upgraded the undersized service panel and set the unit on a new engineered foundation clear of the tree’s root zone. The module landed level, the flat roof drained clean through the first winter rain, and the family’s parents moved in behind the house. They kept the lemon tree.
Dvele Models & Products We Service in Westminster
We service the full Dvele lineup across Westminster and nearby cities like Midway City Dvele service: the detached prefab ADU with its steel-frame modular shell, the studio and one-bed modular configuration, the two-bed modular, and above-garage and garage-adjacent module layouts. When something needs a factory shell component or connection hardware, we source it through Dvele’s manufacturer supply chain so structural and warranty-relevant work stays legitimate. Where the spec allows, we use quality aftermarket HVAC, electrical gear, and plumbing fixtures. That keeps repair costs honest. We also stock common connection hardware and electrical components locally, which means a Westminster service call doesn’t wait on a cross-country shipment.
Dvele Service Pricing in Westminster
Dvele service pricing in Westminster depends on what we’re fixing, but you can expect diagnostic visits to run $150 – $300 depending on the issue. Panel upgrades on older 92683 homes typically land between $2,500 and $5,000 depending on the service size and how much of the original wiring is salvageable. Flat-roof drainage corrections run $800 – $2,000 depending on whether we’re adjusting scuppers or rebuilding a section of slope. Structural shell work gets quoted line-by-line because it always involves the module’s connection points and factory hardware. We give written line-item quotes before work starts, and our estimates are free. Call (855) 949-1913 to schedule a walkthrough and get exact numbers for your unit.

FAQs – Dvele ADU in Westminster
Can a Dvele prefab module actually fit behind the detached garage on a small 92683 lot?
Yes, in most cases, but only if the crane pick and set-down plan are locked before the module is fabricated. We survey the lot, confirm side-yard clearance and lot-coverage limits, and orient the module so the pick can come from the driveway or alley side. On some lots, the garage’s position and a protected tree in the corner force a smaller module or a garage-adjacent configuration instead of a rear-corner set. Call (855) 949-1913 and we’ll tell you honestly whether your lot works.
Will a Dvele all-electric ADU require a panel upgrade on my 1960s Westminster home?
Almost certainly. Most 1960s tract homes in Westminster have 100-amp or smaller service, and a Dvele module’s heat-pump HVAC, induction range, and on-demand water heater pull more than the existing panel can handle. We bundle the panel upgrade and new service drop into the install scope so there’s one permit, one contractor, and one timeline. Call (855) 949-1913 for a free estimate that includes the panel work.
How does Westminster’s coastal marine humidity affect a Dvele flat-roof module?
It means drainage has to be verified, not assumed. Dvele’s low-slope roof panels depend on correct slope and scupper placement to shed water. In Westminster’s humid coastal air and occasional winter rain, incorrect slope shows up as ponding and edge-seam staining. We check slope and scupper positions before the unit is set, then verify drainage after the first real rain. Call (855) 949-1913 to schedule a roof inspection if you’re seeing staining or ponding.
Do I have to remove my citrus or avocado tree to install a Dvele ADU?
Not always. Many Westminster backyards have mature citrus or avocado trees that homeowners refuse to cut down, and we plan around them wherever the root zone and crane path allow. That sometimes means adjusting the module orientation, shifting the foundation, or staging the crane pick differently. If a tree’s root structure endangers the foundation or blocks every viable set-down path, we’ll tell you before you spend a dollar. Call (855) 949-1913 and we’ll walk your lot together.
Are you authorized by Dvele, and does that affect my warranty?
No, we are independent. We’re not manufacturer-affiliated or Dvele-authorized in a corporate sense. We install and service Dvele units as an independent builder who has worked through the factory’s panelized shell, connection detailing, and Title 24 documentation on many Orange County lots. Structurally, we source factory components through Dvele’s supply chain, and warranty-relevant work follows the manufacturer’s specifications. For anything beyond the factory warranty, our workmanship warranty applies. Call (855) 949-1913 and we’ll explain exactly how the warranty splits out.
