Why Upland Homeowners Choose Dvele ADU
Ellery ADU Studio Upland provides Dvele repair in Upland for homeowners who need factory-built unit installation, foundation correction, or system troubleshooting - all under one contract at one written price. We’re one of the few design-build studios in San Bernardino County that has actually delivered and serviced Dvele panelized units, and we know the Dvele installation manual that many local contractors never read. Call (840) 212-3065 to schedule your free estimate.
Dvele’s LUMEN and VUE series have gained traction in Rancho Cucamonga and nearby Upland for a reason. The city’s lot pattern - deep rear yards carved from former citrus groves in the 1950s through 1970s - gives a disproportionate share of homes the raw footprint for a rear ADU without fighting lot coverage. A detached Dvele unit drops onto that footprint faster than stick-built framing, but only if the foundation, electrical service, and utility connections are coordinated to Dvele’s tolerances. That’s where most projects stall.
We’re an independent Dvele service provider, not authorized, sponsored, or warranted by Dvele. We don’t pretend otherwise. What we offer is field knowledge: how the Dvele panelized shell behaves when Upland’s Santa Ana winds hit, how the pre-cut plumbing chases align (or don’t) with clay sewer laterals in older tracts, and how to commission the HRV for 105°F summer highs and cool winter nights. Nadia Ellery and our crew have worked these units through enough permit cycles to know which details stall an approval at Upland Building & Safety and which ones don’t matter.
Why Trust Ellery ADU Studio Upland for Your Dvele ADU?
Our technicians have handled Dvele LUMEN Series, VUE Series, and custom panelized shells in the field. We stock Dvele OEM fasteners, gaskets, and connection hardware because aftermarket substitutions can misalign the pre-cut chases and compromise the structural record. For standard domestic components - PEX, ABS, 200-amp panels - we use quality aftermarket parts that carry the same code listing at a better value.
Nadia Ellery grew up in Santa Monica watching coastal infill housing turn every backyard into a negotiation, then studied architectural drafting at Santa Monica College before moving into full design-build work. She and our crew have been working the Inland Valley for several years now. Most recently we wrapped a detached studio on a corner lot near Upland’s Lemon Avenue corridor. She’s logged enough permit cycles with San Bernardino County - and with Upland’s own Building & Safety department, which runs a separate approval pathway from unincorporated county parcels - to know exactly which details stall an approval and which ones don’t matter.
Every Dvele project we take starts with a written price before any work begins, per Haven Standard Clause 1. Every visit produces a documented photo record. And every finished unit carries our 365-Day Done Right Promise: if it’s not built to the permitted drawings, we make it right - in writing, before the project starts. Read the clause, then read the cost range - if either one surprises you, we haven’t done our job yet.
Common Dvele ADU Problems We Fix in Upland

- Moisture wicking at panel base plates. The Dvele LUMEN Series ships with a factory-installed base gasket, but when the unit is set on a slab that wasn’t finished to Dvele’s foundation tolerance - ±1/4 inch over 20 feet - the panel joints wick groundwater and irrigation runoff. We’ve seen this on multiple Upland properties where the owner had a flat slab poured by a previous contractor. The bottom 12 inches of drywall goes soft, efflorescence blooms on the interior face, and the floor deck drifts out of level. The fix isn’t a patch. We pull the Dvele-set anchors, re-grade or pour a proper stem-wall foundation to spec, replace the OEM base gasket and affected drywall, and re-level the shell.
- Electrical service undersized for Dvele load schedules. Dvele’s panel and load schedule assumes a 200-amp main. Many Upland homes built in the 1950s-1970s still run 100-amp panels with original copper or galvanized supply lines. Add the Dvele unit’s heat-pump HVAC and induction range, and Title 24 compliance becomes impossible without a service upgrade. We flag this during site assessment, price the 200-amp upgrade in the initial written quote, and coordinate with Southern California Edison before the Dvele unit arrives.
- Plumbing chase misalignment with existing sewer laterals. Dvele’s pre-cut plumbing chases are precise - but precise to a standard depth and slope that doesn’t account for Upland’s aging clay or Orangeburg pipe, or for the 5-10% natural grade on north Upland parcels above 19th Street. When the chase and the lateral don’t meet, we re-route. The Dvele installation manual doesn’t cover this; our field crews do, because we’ve mapped enough Upland sewer conditions to know where the conflicts happen.
- HRV condensation and thermal bridging. Dvele’s high-performance envelope performs brilliantly when the heat-recovery ventilator is commissioned correctly. Factory default schedules don’t account for Upland’s hot-dry summer peaks past 105°F and cool winter swings. We’ve found units running factory settings that create positive pressure and moisture accumulation at envelope penetrations. We re-commission to a Upland-specific schedule - higher summer ventilation rate, winter heat-recovery priority - and the bridging stops.
- Foundation out-of-level from stem-wall settling. North Upland’s graded lots often require engineered retaining walls or drilled caissons for a detached ADU pad. When these are underspecified - or when a flat-south-Upland approach is copied onto a sloped lot - the Dvele shell settles unevenly. The panel joints stress. Doors bind. We assess with a laser level, document the deviation, and specify the correct foundation repair before touching the Dvele shell. This is a cost line that routinely surprises owners who priced the job against a flat lot near the 10 freeway.
Dvele Parts & Our Repair-vs-Replace Approach
We use Dvele OEM fasteners, gaskets, and connection hardware for the panelized shell. Aftermarket substitutions can void the Dvele structural record and misalign pre-cut chases. For standard domestic items - PEX, ABS, 200-amp panels, ductless mini-split heads - we use quality aftermarket parts that meet the same code listing.
Our stance is honest. A Dvele shell with good bones and a bad foundation or undersized service is almost always repair-and-upgrade. But a Dvele unit that has been set out of level and has chronic joint failure is usually a re-set, not a patch. We’ll tell you which category you’re in before we write the quote. Call (840) 212-3065 for a free estimate - we’ll bring the laser level and the photo documentation.
Our Dvele Service Process - Step by Step

- 1
Diagnosis with documentation. We arrive with Dvele installation manuals, a laser level, and moisture meters. We photograph every condition - foundation deviation, panel joint integrity, electrical panel rating, plumbing chase alignment - and send you the photo record before we leave. Under Haven Standard Clause 3, you see what we found, not what we felt.
- 2
Written scope and price. We specify OEM or aftermarket parts by line item, note any required electrical or plumbing upgrades, and lock the scope at signing per Clause 5 (No Surprises). No door-side upsells. No scope creep.
- 3
Repair or install with permit coordination. For installations, we pull permits through Upland’s Building & Safety department - not San Bernardino County, not LA County. Upland’s distinct fee schedule and inspection timeline apply. For repairs, we work within existing permitted conditions or pull amendment permits as needed.
- 4
Testing and commissioning. Every Dvele unit gets HRV commissioning to a Upland-specific schedule. Electrical loads are verified against the Dvele panel schedule. Plumbing is pressure-tested and inspected.
- 5
Warranty documentation. We deliver a written record of all work, parts used, commissioning settings, and our 365-Day Done Right Promise. You know the name of every document before we start; you hold every document when we finish.
