Dvele ADU in San Antonio, CA | Ellery ADU Studio
We’re an independent Dvele service provider in Austin and throughout San Antonio, and the quick answer is this: we handle everything from panel joint repair on existing Dvele structures to full panelized installs for casita legalizations, with written pricing before any work starts. The one thing that makes our Dvele work here different is that we already know how these panelized systems behave on San Antonio’s shrink-swell clay and under the Edwards Aquifer impervious-cover caps. That local knowledge means fewer surprises on your permit set and a foundation that doesn’t crack in the first wet-dry cycle.

Why San Antonio Residents Choose Us for Dvele Service
We’ve been specifying and coordinating Dvele panelized systems since the line first gained traction in Texas, and we do it as an independent studio, not a manufacturer-authorized dealer. That independence matters because we’re free to tell you when the factory spec needs a San Antonio-specific adjustment, like butyl flashing rated for 105°F attic temperatures or a post-tension slab where Dvele’s standard foundation detail won’t hold on caliche. Nadia Ellery, our principal, cut her teeth on permit-ready drawing sets in Los Angeles, where the reviewing agency bounced drawings for missing utility tie-in details. She brought that same insistence on documentation to San Antonio, and it’s why our permit sets for Dvele ADUs tend to clear COSA the first time through.
We stock Dvele factory-specified parts from the original equipment vendor for panel joints, flashings, and HVAC connections, and we keep the common consumables in a San Antonio warehouse so we’re not waiting on a California shipment when your casita needs a repair before a military family moves in near Lackland. Every Dvele visit includes a documented photo record of what we found and what we did, and every Dvele project gets a written price before work begins. That’s Haven Standard Clause 1, and it applies to a $900 flashing repair the same way it applies to a $210,000 full Dvele IQ install.
Common Dvele ADU Problems We Solve in San Antonio
- Panel joint separation and hairline cracking at roof-to-wall transitions. On San Antonio’s shrink-swell clay, a conventional slab will move enough in one wet-dry cycle to open hairline cracks at Dvele’s roof-to-wall panel joints. We see this most often on Dvele Adapt structures in Harlandale and Highland Hills where the original install skipped post-tension engineering. We repair the crack, flash the joint properly, and tell you honestly whether the foundation is the real problem.
- Heat-related underperformance of the all-electric HVAC package in Dvele IQ units. A Dvele IQ heat pump that was sized for a mild California climate will struggle through San Antonio’s sustained 100°F+ days with Gulf humidity. The comfort complaint lands by the first August, almost every time. We size a dedicated mini-split to the actual heat load of the unit and the orientation it faces, and we’ve never had a callback after doing it right.
- Water intrusion at window and door flashings after violent late-summer storms. Dvele Adapt panelized structures are particularly vulnerable at flashing points when the original detail didn’t account for San Antonio’s cloudburst rainfall intensity. We replace factory flashings with high-temperature butyl tape and stainless fasteners that outperform the OEM spec in this climate.
- Inadequate grounding and panel bonding on older masonry service panels. When Dvele’s factory electrical rough-in is connected to a 1940s-1960s single-wythe concrete block service panel in Harlandale or Prospect Hill, the ground and bond path often needs a full upgrade. We trace it, document it, and bring the panel bond up to code before any Dvele panel wiring is energized.
- Unpermitted casita legalization where the existing rear structure is masonry, not framed. On the West and South Sides, the typical scenario is a 1950s concrete block detached garage that was never permitted as living space. We handle the permit application, structural review, and the Dvele panel retrofit as one scope, under one written contract.
Dvele Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio’s owner-occupancy requirement tied to ADU permits changes the entire Dvele service conversation here. The rule means the person pulling the permit has to live on the property, which effectively locks out the investor class and concentrates Dvele work in the hands of long-tenured homeowners on the West and South Sides who have an unpermitted casita they need to legalize. We handle more Garage Conversion ADU in San Antonio projects with Dvele panels than most US markets see in a decade. That’s not a marketing line, it’s the shape of the permit log at COSA. Overlay the Edwards Aquifer Recharge and Contributing Zone caps on impervious cover in the north and northwest, and you get a San Antonio-specific fact that no other Texas city shares: the same Dvele Duo that fits comfortably on a Harlandale lot may be refused outright in Stone Oak because the HOA prohibits ADUs, or shrunk in Helotes because the impervious cover budget is already exhausted by the primary home’s driveway and patio. The drawing either satisfies the inspector or it doesn’t. Let’s make sure it does.
Dvele Models & Products We Service in San Antonio
We work on the full Dvele line. The Dvele IQ all-electric flagship shows up in the affluent north-side subdivisions where HOAs allow ADUs, and it’s the model where we most often correct heat pump sizing. The Dvele Adapt panelized line is the workhorse for casita conversions in older masonry neighborhoods like Prospect Hill and Harlandale. The Dvele Duo two-story compact model fits the multigenerational lots near Harlandale and Highland Hills where vertical is the only way to add square footage, making it ideal for a San Antonio New Detached ADU. And the Dvele Mini single-story studio is the one we specify most often for rental-ready units near Lackland AFB, where the PCS cycle means a permitted unit rents quickly to military families. For common consumables like flashings and sealants, we substitute proven aftermarket products rated for San Antonio’s heat and rain, because some factory-specified materials simply weren’t designed for a Texas August. We tell clients plainly when a panel joint crack is cosmetic and repairable rather than structural, and we never push a full wall assembly replacement on a hairline crack.
Dvele Service Pricing in San Antonio
Dvele ADU service in San Antonio falls into predictable bands. A diagnostic visit with a documented photo record runs $150-$300, credited toward the repair if you proceed. Panel joint resealing and flashing replacement on a Dvele Adapt typically lands between $900 and $2,800, depending on access and how many joints are involved. A full heat pump replacement with proper San Antonio load sizing runs $6,500-$14,000. A complete casita legalization with Dvele panels, including permit application, structural engineering, and post-tension foundation work, typically runs $180,000-$260,000 all-in, drawings through final inspection. Every number is a written line-item quote before work starts, never a verbal ballpark. Call (971) 497-2402 for a free estimate on your specific scope.

FAQs - Dvele ADU in San Antonio
Can I legalize my existing unpermitted San Antonio casita with a Dvele panel system instead of building new? Yes, and this is the most common Dvele path we handle in San Antonio. The legalization route requires a permit application through COSA, structural review of the existing masonry shell, and a foundation upgrade that meets current code. We handle the permits, the engineering, and the panel install as one written contract. Call (971) 497-2402 for an exact assessment of your casita.
How does being inside the Edwards Aquifer Recharge or Contributing Zone affect my Dvele ADU footprint? Your total impervious cover, including the ADU footprint, driveway, and patio, is capped at a percentage of your lot. That cap can shrink a Dvele Duo down to a Dvele Mini or kill the project entirely. We run the impervious cover math before you pay for drawings.
Does a Dvele IQ heat pump work in San Antonio’s 100°F humid summers? It works if it’s sized correctly. The installed heat pump must be matched to the actual cooling load of your specific unit’s orientation, glazing, and insulation. Many Dvele IQ units arrive with a heat pump spec’d for a milder climate, and they can’t hold temperature through an August heat wave. We size the replacement or correction properly and document the load calculation. Call (971) 497-2402 for a comfort assessment.
What kind of foundation does a Dvele ADU need on San Antonio’s shrink-swell clay? On caliche and active clay, we recommend post-tension engineering or deep piers rather than a conventional slab. A flat slab without post-tension will crack and separate within a few wet-dry seasons, and the panel joints above it will follow. We include foundation design in every Dvele permit set we produce.
Can I place a Dvele Duo in a Stone Oak HOA community? Usually not. Most Stone Oak and Alamo Ranch HOAs prohibit ADUs outright in their covenants, regardless of what the city allows. We review your HOA’s CCRs before we recommend a model, and we’ll tell you plainly if the project has no path forward in your community.
