Dvele ADU in Austin, CA | Ellery ADU Studio
We provide independent Dvele ADU service across Austin, from East Austin’s pier-and-beam bungalows to the limestone lots west of I-35. Our Dvele work here is different because we plan around what Austin actually does to a factory-built home: expansive clay that shifts screw-pile foundations, 100°F+ summers that push ERV and heat-pump systems hard, and a permitting environment where the HOME ordinance lets you add units faster than your electrical panel can keep up. We are not Dvele authorized or manufacturer-affiliated. We’re a design-build studio that has specified and serviced Dvele’s modular lines since 2015, and we quote every job in writing before work starts. Call (971) 497-2402 to schedule a site assessment.
Why Austin Residents Choose Us for Dvele Service
Roughly 900 ADUs designed, permitted, and built since 2015, every one with a written price before work started and a documented photo record when work was complete. Most Austin homeowners we meet did not plan to need Dvele service. They bought a factory-built ADU because the site made sense and the unit went up fast. Then the soil moved, or the roof pooled after a downpour, or the second unit they wanted to add ran into a maxed-out panel. We know Dvele’s envelope and mechanical systems well enough to diagnose those problems without guessing. Nadia Ellery, our principal, studied architectural drafting and construction management at Los Angeles Trade-Technical College and spent the better part of a decade in residential design-build before founding this studio. The drawing either satisfies the inspector or it doesn’t. Let’s make sure it does. We bring that same standard to Dvele service in Austin: factory-equivalent materials, matched to Dvele’s original specs, never a generic substitute. See our full Dvele sales & service scope for how we work with these systems.
Common Dvele ADU Problems We Solve in Austin
- Screw-pile foundation brackets loosening in expansive clay. East Austin’s Blackland Prairie clay swells when wet and shrinks when dry. That wet-dry cycle works screw-pile brackets loose over time, which causes minor racking of panel joints. We re-level the module and re-torque brackets to Dvele’s spec before the panel joints start binding.
- ERV and heat-pump underperformance during 100°F+ summers. Cedar pollen and dust clog outdoor air intake filters faster in Austin than in almost any market we serve. A clogged filter chokes the ERV, and the heat pump runs harder trying to hold temperature. We replace filters, clean coils, and verify refrigerant charge as part of routine Dvele service.
- Flat membrane roof pooling after sudden downpours. Austin storms drop a lot of water fast. Dvele’s lower-slope modules can pool at membrane seams, which wears them prematurely. We inspect seams, repair worn areas with factory-equivalent membrane, and correct drainage where the module allows it.
- Tyvek and flashing peeling at west-facing window corners. UV exposure and Austin’s thermal cycling are hard on factory-applied flashing. We see this most on west-facing Dvele units with no shade. We remove the failed flashing, re-seal per Dvele’s original detail, and document every step with photos.
- Electrical panel maxed out before a second ADU goes in. The HOME ordinance makes it easy to add a second unit. Your original 100-amp panel from the 1970s does not care. We see this constantly. We spec a service upgrade before the second Dvele unit gets energized.
Dvele Service in Austin: What Local Conditions Mean for Your Equipment
Because Austin’s HOME ordinance allows up to three residential units by right on any single-family lot citywide, Dvele owners often add a second Garage Conversion ADU in Austin or another unit within a year. We regularly encounter their first Dvele unit’s electrical panel already maxed out, requiring a service upgrade before installing the second unit. This is unique to Austin. In most Texas cities, you fight a variance process for one ADU, let alone two. Here, the bottleneck is not city approval. It is the original 1940s-era service panel in a bungalow off Manor Road, or a 2001 subdivision panel in South Manchaca with no spare breaker slots. A homeowner sees open lot space and thinks the second unit is straightforward. The panel says otherwise. We catch that before it becomes an energized-building problem, and we put the upgrade in the written scope under Haven Standard Clause 5 (No Surprises). That means no door-side upsell, no scope creep, and no second Dvele ADU sitting dark because nobody checked the service size first.
Dvele Models & Products We Service in Austin
We service the full Dvele line that has been installed across Austin: Dvele IQ, Dvele Origin, Dvele Adapt, and Dvele One. Each model line has its own envelope and mechanical details, and we match materials accordingly. For Dvele’s airtight sealing and moisture-management components, we use factory-equivalent materials, never generic substitutes. When a Dvele module’s framing or paneling is compromised beyond a 10% area, we recommend whole-panel replacement over patching. Partial fixes interrupt the continuous air barrier, which undermines the home’s energy performance, and in an Austin July that means a unit that cannot hold temperature. We stock common Dvele-compatible parts locally for faster turnarounds here than our other Texas markets. See our broader Austin service area for where we work.
Dvele Service Pricing in Austin
Dvele service pricing in Austin depends on what we find, not on a flat rate we invented before looking. A screw-pile re-leveling with bracket re-torquing typically runs $1,800 to $3,400, depending on how many brackets have moved and whether we need to re-seal panel joints. ERV and heat-pump service, filter replacement, coil cleaning, and refrigerant verification, runs $350 to $700 per visit. Membrane roof seam repair runs $900 to $2,200 depending on linear feet and access. A service panel upgrade before a second ADU runs $3,500 to $6,000 all-in, permit included. Every job gets a written price before work starts, per Haven Standard Clause 1. No exceptions. Call (971) 497-2402 for an exact scope and number for your Dvele unit.

FAQs - Dvele ADU in Austin
Expansive clay swells when wet and shrinks when dry, which loosens screw-pile brackets over successive seasons. A Dvele unit on Blackland Prairie clay should have brackets re-torqued and module level re-checked every 18 to 24 months. Call (971) 497-2402 to schedule a foundation assessment with a written report.
Yes, if the ERV and heat pump are maintained, and if the unit was sized for the load. Unshaded west-facing Dvele units in Austin run harder than shaded ones, which means filters clog faster and coils need cleaning more often. If your unit has not kept temperature since day one, the sizing was likely wrong. Call (971) 497-2402 and we will measure the actual load against the installed equipment.
Often yes. Waller Creek and its mapped tributaries cut through dozens of older residential lots in the 78721 and 78702 ZIP codes, even where no water is visible. A Dvele unit on a flagged lot can need a FEMA elevation certificate, fill permits, and additional review before service work that touches foundation or drainage can proceed. Call (971) 497-2402 and we will check your address against the city’s floodplain map before quoting.
That depends on the warranty language and the storm. Factory-applied membrane and flashing failures from normal UV and thermal cycling are often excluded after a set period. Hail damage is typically handled through homeowner’s insurance, not the Dvele warranty. We document the roof condition with photos so you have evidence for whichever path applies. Call (971) 497-2402 for a documented roof inspection.
For an Austin New Detached ADU, site work, foundation, and module placement on a 50×120 lot typically takes 4 to 8 weeks depending on soil conditions and whether floodplain review applies. The Dvele module itself goes up fast. The foundation and utility work before it does not. Call (971) 497-2402 for a written timeline based on your specific lot, not a generic answer.
