Dvele ADU in Chino Hills, CA | Ellery ADU Studio Chino
We provide independent Dvele prefab and modular ADU Design & Permitting - Chino Hills service across the area, from garage conversions using Dvele panelized packages to full detached Origin and LUMO module installs on hillside lots. The one thing that makes our Dvele work here different: we’ve navigated the triple-approval reality that flat-lot installers from neighboring cities routinely miss - city permits, HOA architectural review, and Chino Hills State Park defensible-space clearance.

Why Chino Hills Residents Choose Us for Dvele Service
We’ve concentrated on Dvele factory-built modules since their panelized systems began appearing on Chino Hills hillside lots, and our crew has worked through their wiring schematics, structural connection details, and Title 24 packages on dozens of installs. We are not Dvele dealers, authorized representatives, or warranty agents - we simply know their product better than general contractors who treat it like a black box.
Nadia Ellery, our owner, grew up on job sites watching her uncle retile bathrooms, then studied architectural drafting and building technology at Santa Monica College before spending two decades in residential design-build. She’s handled everything from permits to punch lists. Her go-to example is a detached unit near Ayala Park that needed three rounds of city comment responses before the permit issued - now she uses it to show clients why documentation matters more than optimism. The document either says it or it doesn’t.
Under Dvele sales & service, we stock OEM structural connectors, gaskets, and electrical harnesses locally for Chino Hills jobs, and we pull permits ourselves rather than handing you off to a separate designer. Every project runs under The Haven Standard: a written price before work starts, a documented photo record on every visit, and our 365-Day Done Right Promise backed in writing.
Common Dvele ADU Problems We Solve in Chino Hills
- Factory-sealed wall and roof panels arrive racked, causing door and window frames to bind after modules are set on engineered foundations. Chino Hills’ expansive clay soils shift seasonally, and we’ve re-shimmed panel connections on sloped lots off Rolling Ridge Drive where pier-and-grade-beam foundations settled differently than the factory assumed.
- Mini-split condensers undersized for 100-108°F valley heat. The bowl-shaped terrain traps hot air, and Dvele’s standard HVAC specs often can’t keep up. We size replacements using actual Manual J load calculations for Chino Hills, not factory defaults.
- Pre-wired electrical harness conflicts with SCE service drops on 1980s-2000s stucco-and-tile homes. Many original panels are 125A or 150A, and Dvele’s integrated load center sometimes forces a meter-main relocation that flat-lot electricians don’t anticipate.
- Moisture intrusion at panel-to-panel gaskets on detached ADUs near Chino Hills State Park open space. Defensible-space clearing and slope drainage expose module bases to seasonal runoff that factory gasket specs weren’t designed for.
- HOA architectural committees flag exterior colors or roof profiles even after AB 670 limited their veto power. We document compliance and negotiate paint palette approvals without altering Dvele factory finishes.
Before
AfterDvele Service in Chino Hills: What Local Conditions Mean for Your Equipment
Because so many Chino Hills detached ADU sites back onto Chino Hills State Park open space - throughout Rolling Ridge, Carbon Canyon, and Los Serranos-adjacent areas - Dvele module placement often has to satisfy defensible-space clearing and slope-drainage review in addition to city permits and HOA architectural sign-off. That’s a triple gauntlet. Flat-lot Dvele installers from Chino or Ontario routinely miss it.
We installed a Dvele two-bedroom modular ADU on a sloped lot off Rolling Ridge Drive where the soils report required a pier-and-grade-beam foundation, and after setting the modules we found the factory door frames had racked enough to bind - our tech re-shimmed the panel connections, replaced two OEM gaskets, and upsized the mini-split condenser to handle the 105°F summer afternoons. The HOA architectural committee had also flagged the exterior color, so we documented AB 670 compliance and got the paint palette approved without changing the Dvele factory finish.
The Chino Hills formation’s expansive clay means even modest slopes need soils reports and engineered foundations. A general contractor who quotes a standard slab hasn’t read the geotechnical reality. We build that into our written scope from day one.
Dvele Models & Products We Service in Chino Hills
We work across Dvele’s full residential line: the LUMO series (studio and one-bedroom prefab modules), the Origin series (two-bedroom modular ADU), and custom panelized detached ADU packages for garage conversions or rear-yard builds. Our Chino Hills inventory includes OEM structural connectors, panel gaskets, and electrical harnesses - the parts that touch the weather envelope or affect warranty coverage. For mini-split and finish components where Dvele OEM lead times stretch to months, we use high-quality aftermarket equivalents and document the substitution in your permit set.
If a module has racked beyond tolerance or its panelized shell has delaminated, we tell homeowners honestly that re-setting or partial rebuild beats patching. We scope that before recommending replacement. No surprises.
Dvele Service Pricing in Chino Hills
Prefab ADU installation in Chino Hills typically runs $85,000-$165,000 all-in for a LUMO or Origin module, including foundation, utility tie-ins, and final inspection. Garage conversion ADUs using Dvele panelized packages usually fall between $65,000-$110,000, drawings through final inspection. Foundation and grading on hillside lots adds $15,000-$40,000 depending on soils reports and engineered pier requirements.
What drives cost: slope and soils complexity, SCE electrical panel upgrades, HOA documentation time, and whether defensible-space clearing is required. Every project is quoted with a written price before any work begins, per Haven Standard Clause 1. No call-for-a-quote runaround.

FAQs - Dvele ADU in Chino Hills
Yes, but the foundation design must be engineered for Chino Hills’ expansive clay soils, not a standard slab. We coordinate the soils report, pier-and-grade-beam design, and Dvele’s structural connection details as one scope. Call (909) 323-1107 to schedule your free estimate.
No. AB 670, effective 2020, bars California HOAs from outright banning ADUs. However, Chino Hills HOAs can still enforce reasonable design guidelines - exterior colors, roof pitch, setbacks - and many are still writing compliance policies. We document AB 670 compliance and negotiate with HOA architectural committees so your Dvele factory finish stays intact.
The valley bowl traps 100-108°F heat, and Dvele’s standard HVAC specs often undersize the condenser for that load. We replace with properly sized units based on actual Manual J calculations, not factory defaults. Call (909) 323-1107 for an exact quote - estimates are free.
Yes. Most Chino Hills homes from the 1980s-2000s have attached two-car garages that convert well using Dvele panelized wall and roof packages - a Garage Conversion ADU in Chino Hills specialty we handle start to finish. We handle the permit set, Title 24 compliance, and HOA sign-off as one contract. The existing slab is usually 4 inches - within range for conversion, though we’ll tell you exactly what that means for your foundation line item.
We photograph everything before the crane sets it down. Minor racking gets corrected with OEM gasket replacement and panel re-shimming. If structural damage exceeds tolerance, we document it and scope re-setting or partial rebuild before any patchwork. Under Haven Standard Clause 5, the scope is locked at signing; no door-side upsells, no scope creep.
