Dvele ADU in San Bernardino, CA | Sunburst ADU Builders
We provide independent Dvele ADU service across San Bernardino, from the older core near Baseline to the newer subdivisions pushing north, and also offer Dvele in Rialto for homeowners just west of the city. The thing that makes our Dvele work here different is simple: we know what the factory package covers and what the city of San Bernardino, the summer heat, and a mid-century 100A panel will demand on top of it. Most Dvele owners call us after they’ve already discovered that gap the hard way. Call (855) 676-6807 if you’re planning a Dvele ADU or already own one that’s not performing.
We’re a Dvele-experienced builder, not a Dvele dealer. That independence means we’ll tell you straight when a factory spec is wrong for this city and when it’s fine as-is. Our team has worked Dvele’s panelized and modular systems across the Inland Empire long enough to know how their wall cassettes, roof modules, and factory electrical rough-ins actually land on a San Bernardino lot, and where the factory package ends and the site work begins. We offer full Dvele sales & service support, from first lot assessment through finished unit.

Why San Bernardino Residents Choose Us for Dvele Service
Dvele builds a genuinely tight shell. The panelized wall system and factory mechanical core are well-engineered. But a Dvele module is a product that has to interface with a specific piece of land, a specific house, and a specific city’s plan-check desk. That interface is where most problems live, and it’s exactly where we work.
Noel Carrasco grew up off Baseline Street in Highland and has watched this part of the Inland Empire change more in the last decade than in the previous three combined. He learned framing, finish, and permits through the Building Technology program at San Bernardino Valley College, then spent years working every phase of a build before narrowing his focus to ADUs. When a San Bernardino homeowner asks whether a Dvele will pencil out on their lot, they get an answer from someone who has actually built here, not a sales script. Our San Bernardino service area coverage means we’re already familiar with the plan-check quirks and pre-1980 lot stock that define this city.
Common Dvele ADU Problems We Solve in San Bernardino
- Cooling load mismatch on 100°F+ days. Dvele’s factory cooling spec is sized for a milder climate. San Bernardino summers regularly crack triple digits, and the single-zone mini-split that ships with the shell can’t always hold rear bedrooms under load. We re-run the load calc and add shading where it matters.
- Santa Ana wind-driven water intrusion. Panel joint and roof module seams need the factory’s exact sealant schedule. When an install crew skips or rushes it, wind-driven rain during Santa Ana events finds the gaps, especially on foothill-side lots where gusts are stronger.
- Undersized module tie-downs. Dvele’s anchor spacing is engineered for generic wind zones. San Bernardino’s exposure demands re-verification. We routinely find anchor counts too low on installs done by crews unfamiliar with the local wind rating.
- Factory electrical rough-in vs. a 100A legacy panel. Much of San Bernardino’s housing stock is mid-century with original 100A service. The Dvele package’s mechanical core simply can’t be added without a panel upgrade and often a new mast and drop. The factory package doesn’t include that work.
- Lot-coverage math that doesn’t close. Wide, shallow 1950s – 60s lots with a detached garage usually leave a narrow side or rear yard. Dvele’s standard module footprint can push right up against setbacks. We re-lay the site plan before you commit to a module size.
Dvele Service in San Bernardino: What Local Conditions Mean for Your Equipment
San Bernardino’s plan-check desk sees so many ADU submittals that Dvele’s factory drawings routinely get flagged for missing site-specific items the factory doesn’t supply. The two that come up most are lot-coverage math against the existing garage and the wind/seismic tie-down sheet for our exposure. A Dvele package here needs a local site sheet built around it before it clears. That’s not a knock on Dvele; it’s just the reality of a high-volume building department in a city where the housing stock is mostly 1940s – 1970s single-story tract homes. On a wide 1950s lot off the older core near the 215, a homeowner had a two-module Dvele 2-bed set on a slab our crew poured after re-grading for drainage. The factory’s mini-split struggled through the first July. We re-ran the load calc, added exterior shading on the west module face, and bumped the service to a 200A panel because the original 100A main couldn’t carry the ADU’s mechanical core. The unit now holds setpoint through 105°F afternoons. Your lot probably has more potential than you think. Let’s find out for sure.
Dvele Models & Products We Service in San Bernardino
We work the full Dvele lineup: the detached modular ADU in studio and 1-bed factory modules, the two-module 2-bed ADU package, the panelized/cassette wall system for site-assembled units, and the net-zero-ready shell package with factory-installed mechanical core. For anything structural or envelope-critical (module connectors, panel gaskets, roof seam sealants, anchor hardware) we use Dvele’s factory parts only. Substitutions void the engineered assembly, and we’re not willing to do that. For mechanical, electrical, and finish items we spec quality field-available components. We’re honest about when a Dvele shell is worth repairing versus re-specifying. If the module framing or panel system is compromised, a repair rarely pencils out.
Dvele Service Pricing in San Bernardino
Service pricing depends on whether you’re planning a new Dvele install, correcting an existing one, or upgrading site infrastructure like electrical service before a module lands. A full Dvele ADU project in San Bernardino, including site prep, foundation, panel upgrade if needed, module placement, and finish work, runs higher than a standard stick-built shell simply because you’re paying for factory engineering plus local adaptation. Repair scopes vary: re-sealing roof seams, re-torquing tie-downs, or re-commissioning a struggling mini-split are smaller jobs. A full panel upgrade on a mid-century home with 100A service is its own line item. We give written line-item quotes, and estimates are free. Call (855) 676-6807 for an exact number on your Dvele project in San Bernardino.

FAQs – Dvele ADU in San Bernardino
Yes, most of the time. San Bernardino’s mid-century homes were built for 100A service, and a Dvele module with its factory mechanical core pulls enough load that adding it to an original panel usually isn’t code-compliant. We specify the panel and mast/drop upgrade as part of the site work, and it’s about the least glamorous but most important line item in the whole project. Call (855) 676-6807 for a site-specific answer on your home’s service.
We re-verify the anchor count and spacing against San Bernardino’s specific wind exposure rather than trusting the factory’s generic wind-zone spec, and we bring the same rigor to our Dvele in Highland projects where foothill exposure is even more severe. On foothill-side lots we typically add anchors, and we document everything for the city’s tie-down sheet. A Dvele shell that’s under-anchored is a problem waiting for the first big Santa Ana event.
Often yes, but not always with the module orientation you first pictured. Wide, shallow lots in San Bernardino force detached ADUs into side yards or narrowed rear setbacks. We re-lay the site plan against the city’s lot-coverage and setback math before you lock in a Dvele module size. Sometimes a single-module Dvele works where a two-module won’t.
This is common in San Bernardino. The unpermitted unit has to be dealt with before or alongside the Dvele install, because the city won’t sign off on a new dwelling while illegal square footage sits on the same parcel. We handle the legalization path and sequence it with the Dvele work so you’re not stalled on plan check.
No, not on its own. Dvele’s factory cooling is sized for a milder climate, and San Bernardino’s regular 100°F+ runs push the single-zone mini-split hard. Rear bedrooms run hot unless we re-check the load calc, add exterior shading on western exposures, and sometimes upgrade the mechanical spec. Plan for that at the front end and you won’t be sweating in July. Call (855) 676-6807 to get a free estimate on making your Dvele actually comfortable here.
