Dvele ADU in Tustin, CA | Ellery ADU Studio Irvine
Dvele prefab ADU installation and service in Tustin typically runs $285,000-$420,000 all-in, including design, permit set, module delivery, crane set, and final inspection. The one factor that changes every Tustin quote is whether your property sits in Old Town’s Historic Resources district or in a Tustin Legacy planned community, because the permitting path and module modifications diverge completely. We are Ellery ADU Studio Irvine, an independent Dvele specialist - not manufacturer-authorized - and we’ve commissioned, installed, and repaired Dvele modules across Tustin service area since 2015.

Why Tustin Residents Choose Us for Dvele Service
We’ve worked on Dvele’s structural panel system, factory electrical chases, and finish schedules across Orange County, including multiple installs in Tustin’s Columbus Grove and Old Town neighborhoods. That repetition matters. When a crane-set module arrives with a loose PEX fitting or a panel seam that needs attention, we’ve already seen the failure mode and stock the OEM part.
Nadia Ellery, our owner, grew up in Santa Monica watching her father pull permits and argue with inspectors about footer depth. She studied architectural drafting and construction technology at Santa Monica College before spending the next fifteen years in design-build work that eventually brought our crew east into Orange County. We’ve logged years of projects across Irvine, including detached studio builds in the Woodbridge Village corridor, and we’re known specifically for delivering permit-ready drawing packages that don’t come back from the city with correction letters. The drawing either passes plan check or it doesn’t. Let’s talk about which one yours will be.
Our Dvele sales & service work is governed by The Haven Standard: a written price before work starts, a documented photo record on every visit, and a 365-Day Done Right Promise backed in writing. No designer-versus-builder blame gap. One contract, one written price.
Common Dvele ADU Problems We Solve in Tustin
- Crane-set panel seam cracking in Tustin Legacy. Dvele LUMEN and VISTA modules set on ground screws in Columbus Square or Greenwood often develop hairline cracks at panel seams when the foundation isn’t perfectly leveled on the former MCAS Tustin base fill soil. We re-level and re-seal with OEM structural connectors, then document the repair with photos for your record.
- Undersized mini-split cycling in August heat. Dvele ATRIUM units ship with condensers sized for milder coastal zones. Tustin’s mid-90s summer peaks and Santa Ana wind events push those units into short-cycling and icing. We spec aftermarket line sets and upsized condensers that actually hold setpoint when the thermometer hits 96°F.
- Transport-loosened PEX manifold leaks. Factory-installed PEX fittings in Dvele modules can vibrate loose during delivery. In Tustin’s Old Town, where the module often sits while Cultural Resources review drags on, that slow leak stays hidden inside wall cavities until the first hot-water demand cycle. We pressure-test every manifold before close-in.
- Cultural Resources rejection on Old Town Craftsman properties. Dvele’s stock smooth siding and stock window proportions fail compatibility review for Historic Resources Inventory homes near El Camino Real or Main Street. We re-clad with lap siding and swap for divided-light windows before the permit set goes in, not after the city returns it.
- HOA utility tie-in disputes in Tustin Legacy. Columbus Grove and similar planned communities have HOA-managed shared infrastructure that complicates sewer and electrical tie-ins. We handle the CC&R review and coordinate with the HOA’s engineer, because AB 3182 overrides the ADU ban but doesn’t override the utility easement rules.
Dvele Service in Tustin: What Local Conditions Mean for Your Equipment
Tustin is split between two worlds, and your Dvele module will live in one of them. In Old Town, a 1920s Craftsman bungalow on the Historic Resources Inventory triggers a Cultural Resources compatibility review that examines your ADU’s window proportions, siding material, and roof pitch against the primary structure’s Craftsman detail. One block east, in unincorporated Orange County, that review simply does not exist. For Dvele owners, this means we often re-clad the module’s smooth factory panels with Craftsman-style lap siding and replace stock windows with divided-light units before ADU Design & Permitting in Tustin submission. The factory finish schedule gets modified, not followed. In Tustin Legacy, the old MCAS base soil and HOA-managed infrastructure create a different problem set: ground-screw leveling on fill, utility coordination through association engineers, and Title 24 compliance on smaller lot footprints where shading from neighboring units affects solar calculations. Same Dvele module, two completely different preparation paths. We know which path your property is on before we write the price.
Dvele Models & Products We Service in Tustin
We specify and coordinate all Dvele product lines within our single-contract design-build model:
- Dvele LUMEN series - single-story prefab ADU, most common for Old Town rear-yard placements
- Dvele VISTA series - two-story prefab ADU, used where Tustin Legacy lot coverage allows vertical build
- Dvele ATRIUM series - studio and one-bedroom configurations, frequent choice for garage-conversion JADUs
- Dvele Custom Modular line - site-specific prefab designs for constrained or irregular Tustin lots
We stock OEM Dvele structural connectors, electrical harnesses, and PEX manifolds locally for fast Tustin turnaround. When OEM lead times exceed two weeks, we use high-quality aftermarket mini-split line sets and insulation - always disclosed, never substituted without written approval. We recommend repair over replacement unless structural panel delamination or repeated water intrusion makes the unit unsafe.

FAQs - Dvele ADU in Tustin
No. Dvele modules typically use ground-screw or pier foundations that minimize disturbance to mature landscaping and aging root systems common on Old Town’s 1920s lots. The foundation design is module-specific, not neighborhood-specific, though Historic Resources review may require screening or architectural integration that affects the foundation’s visual exposure - a common consideration for a Garage Conversion ADU - Tustin project as well. Call (657) 233-9738 to discuss your specific lot conditions.
Properties on the Inventory must pass Cultural Resources compatibility review for materials, massing, and architectural detail. For Dvele modules, this usually means re-cladding smooth factory panels with lap siding and substituting divided-light windows for stock units before permit submission. We handle this modification in our design-build scope, not as a surprise add-on. Call (657) 233-9738 for a written price that includes these revisions.
Yes. California’s AB 3182 legally overrides HOA covenants that prohibit ADUs, including those in Columbus Grove, Columbus Square, and Greenwood. The HOA retains authority over utility easements, architectural guidelines, and construction hours, so coordination is still required. We handle the CC&R review and HOA engineer correspondence as part of our standard permitting scope.
A Dvele ATRIUM in Tustin typically needs a 24,000 BTU condenser minimum, upsized from the 18,000 BTU unit often spec’d for coastal California. Tustin’s inland position pushes regular summer highs into the mid-90s with Santa Ana wind events that add sensible load. An undersized unit short-cycles, ices up, and fails to hold setpoint. We size mechanicals using Tustin’s actual climate zone data, not the factory default. Call (657) 233-9738 to review the mechanical scope for your specific module.
We source OEM Dvele structural connectors, electrical harnesses, and PEX manifolds for warrantied compatibility. For mini-split line sets and insulation, we use high-quality aftermarket parts when OEM lead times exceed two weeks, with written disclosure before substitution. Our default is repair over replacement unless structural panel delamination or repeated water intrusion makes the module unsafe. Call (657) 233-9738 to schedule service.
