Dvele ADU Service Nationwide

Why Chino Homeowners Choose Dvele ADU

We provide Chino Dvele service in Chino, CA for LUMO and VAGA series modules, from site assessment and foundation correction to utility commissioning and final inspection. Our work focuses on the gap between Dvele’s factory-built precision and what Chino’s clay soils, HOA density, and San Bernardino County plan check actually require on the ground. We are not affiliated with, authorized by, or endorsed by Dvele. Call (909) 323-1107 to schedule your free estimate.

Dvele’s prefab approach appeals to Chino owners for good reason. The LUMO studio and 1-bed units, and the larger VAGA 1-bed and 2-bed modules, arrive nearly complete - walls, roof, MEP rough-in, and finishes built in a controlled factory environment. That factory precision is real. What we’ve learned across dozens of Dvele installs in Chino and the Inland Empire is that the precision stops at the property line. The module still has to land on a foundation that matches its steel chassis pier schedule, still has to tie into existing electrical, plumbing and gas in a city where many lots were carved from dairy land in the 1980s and 1990s, and still has to clear plan check with documentation that goes beyond Dvele’s standard structural and energy package.

Chino’s lot sizes help. The 8,000-12,000+ square foot parcels common in master-planned communities built on former dairy land give physical room for a detached ADU that tighter coastal lots simply don’t have. But those same communities often carry an HOA, and a persistent but incorrect belief that HOA rules forbid ADUs. California Civil Code §4751 (AB 670) bars that prohibition. The space is there. The legal right is there. The gap is in ADU Design & Permitting execution - getting the Dvele module from truck to permitted, commissioned, livable unit without the foundation mismatch, utility conflict, or documentation shortfall that stalls projects for months.

That’s where our work starts. Not with sales. With a site assessment that checks the actual soil conditions, the actual slope, the actual panel and sewer lateral locations, and - for north and west Chino lots - the actual airport influence area map against the Chino Airport (CNO) Part 77 obstruction surfaces. A two-story Dvele module in the wrong spot can trigger an FAA informal aeronautical study that adds weeks nobody budgeted for. We check it first. The document either says it or it doesn’t.

Why Trust Ellery ADU Studio Chino for Your Dvele ADU?

We’ve commissioned enough Dvele modules to know the chassis rail spacing on a LUMO studio by sight, to recognize when a VAGA 2-bed’s service bay is oriented for a lot configuration that doesn’t match the actual utility stub locations, and to spot a weather-seal gasket compression set before the first rain proves it. That familiarity comes from hands-on work, not from reading spec sheets.

Nadia Ellery, our owner, studied architectural drafting and building technology at Santa Monica College before spending the better part of two decades in residential design-build, from permits to punch lists. She grew up on job sites watching her uncle retile bathrooms, and she stopped thinking of construction as a mystery before most of her clients were born. For the past several years she and our crew have worked across Chino - including a detached unit on a tight lot near Ayala Park that required three rounds of city comment responses before the permit issued. That project is now our standard example of why documentation matters more than optimism. She is known in this market for giving clients an honest dollar range on the first call and a written scope before anything is signed.

Our technicians are background-checked, uniformed, and trained specifically on prefab and modular systems. We stock Dvele OEM structural connectors, weather-seal gaskets, and service-bay components locally for fast turnaround, and we substitute equal-or-better rated aftermarket parts only when OEM lead times would stall a set. Every project is governed by The Haven Standard: a written price before work starts (Clause 1), a documented photo record on every visit, and a 365-Day Done Right Promise backed in writing. If the finished work is not built to the permitted drawings, we make it right. No designer-versus-builder blame gap exists here - design, permitting, and construction are a single contract at a single written price.

We are state-licensed, insured and bonded, and our license number appears on every page. A live person answers calls 24/7. No voicemail queue, no callback promise that doesn’t materialize.

Common Dvele ADU Problems We Fix in Chino

• Foundation mismatch on the steel chassis. Dvele modules arrive on a steel chassis sized for a specific pier layout. Chino’s expansive clay soils, legacy of agricultural use, swell and shrink with moisture changes. A slab poured to generic dimensions often doesn’t match the Dvele chassis schedule, leaving the module out of level, entry doors binding, and wall seams stressed. We re-shoot the pad, over-excavate and re-compact the clay, and set new piers to the exact Dvele specification. On one Chino job, a LUMO studio sat on its chassis for months because the previous contractor’s slab was two inches off in one corner. We rebuilt the foundation, and the door swing and seam gaps now sit within Dvele’s published tolerances.
• Utility connection conflicts at the chassis service bay. Dvele homes ship with a defined electrical, plumbing and gas penetration schedule. On tight Chino lots, the existing panel, sewer lateral, or gas stub frequently lands where the Dvele service bay cannot reach. This isn’t a design flaw - it’s a site-specific reality. We relocate the connection points rather than forcing a tie-in that strains the module’s MEP rough-in. That relocation requires coordination with Southern California Edison, the Chino Public Works Department, and sometimes the HOA’s architectural committee for trench routing.
• Shipping and crane-set damage to panelized seams. Dvele’s wall and roof panels mate with gasketed joints designed to flex slightly during transport and set. Improper crane rigging, a windy set day, or a foundation that forces the module to twist during placement can compress or tear those gaskets. The damage is often invisible until the first rain or the first 105-degree summer day, when thermal expansion opens the gap. We inspect every seam with a thermal camera and re-seal with OEM gaskets where the original seal is compromised.
• Permit and Title 24 documentation gaps. Dvele provides its own structural and energy package, but Chino and San Bernardino County plan check often wants local climate-zone calcs, HOA submittals, and a site-specific foundation letter that is not in the standard Dvele set. We’ve had plan checkers request geotechnical reports specific to the expansive clay, or Title 24 compliance documentation recalculated for Chino’s inland climate zone rather than the zone Dvele’s package assumes. We prepare these documents as part of our permit set, not as change orders after the fact.
• Mini-split sizing and insulation detailing for Chino’s heat. Dvele’s standard HVAC package assumes moderate California coastal conditions. Chino’s 105-112°F summer highs make passive cooling inadequate. We re-spec mini-split systems sized aggressively for the inland heat load, and we verify that radiant barrier sheathing and insulation detailing match the thermal performance the Title 24 calc promises. A unit that passes on paper but overheats in August fails the owner, not the code.

Dvele Parts & Our Repair-vs-Replace Approach

We use Dvele OEM structural connectors, weather-seal gaskets, and service-bay components wherever they are available. Our Chino warehouse stocks the common LUMO and VAGA gasket sets, chassis anchor bolts, and service-bay relocation kits for fast turnaround. We substitute equal-or-better rated aftermarket parts only when OEM lead times would stall a set - typically on older module revisions where Dvele has discontinued the original component.

Our honest stance: Dvele modules are worth repairing and commissioning rather than replacing. The factory build quality is high, and most problems we see trace to site conditions or installation errors, not to the module itself. But if a module has structural chassis damage from shipping, or is sited on a foundation that has failed due to expansive clay heave, a reset and foundation upgrade is usually the right call over a rebuild. We will tell you which category your project falls into, with documentation, before any work starts. Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing; no door-side upsells, no scope creep.

Our Dvele Service Process - Step by Step

1. 1
   Site assessment and documentation. We survey the actual lot conditions - slope, soil type, utility stub locations, HOA requirements, and airport influence area for north and west Chino parcels. You receive a documented photo record of everything we find, with notes on what it means for your foundation line item and utility connection scope.
2. 2
   Foundation and grading correction. If the existing pad or pier plan doesn’t match the Dvele chassis schedule, we over-excavate, re-compact the expansive clay, and pour to the module’s exact tolerances. We do not set a module on a foundation that forces it out of level.
3. 3
   Module set, seam seal, and MEP commissioning. We crane-set or roll-set the Dvele module, verify every panel seam with thermal imaging, re-seal with OEM gaskets where needed, and relocate or extend electrical, plumbing and gas connections to match the service bay. Every connection is pressure-tested or load-tested before cover.
4. 4
   Permit closeout and final inspection. We submit the site-specific documentation Chino and San Bernardino County require - climate-zone Title 24 calcs, geotechnical letters, HOA approvals - and walk the inspector through the completed work. We do not hand you a certificate of occupancy and disappear.
5. 5
   365-Day Done Right follow-through. If anything we built does not match the permitted drawings, we make it right. The promise is in writing before the project starts, per The Haven Standard.

Dvele Products We Service & Install in Chino

We work across the full Dvele residential line: the LUMO series in studio and 1-bedroom configurations; the VAGA series in 1-bedroom and 2-bedroom layouts; Dvele two-story prefab modules; and Dvele garage-conversion and JADU packages. For each, we stock the chassis-specific anchor hardware, wall-to-roof gasket sets, and service-bay extension kits most commonly needed for Chino’s lot conditions. We do not stock full modules - Dvele ships those factory-direct - but we maintain the site-side parts inventory that keeps a delayed project moving once the truck arrives.

We Also Service These Brands

Our prefab and modular fluency extends beyond Dvele. We specify and coordinate Abodu, Cover, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie systems within the same single-contract design-build model, including Dvele ADU in Eastvale, CA projects. If you are comparing brands, we can evaluate which system’s chassis geometry, service bay orientation, and standard foundation plan best fits your specific Chino lot. The analysis is part of our free estimate.
