Dvele ADU in San Bernardino, CA

Dvele ADU in San Bernardino, CA | Home Base ADU Builders

We provide independent Dvele ADU service across San Bernardino, from foundation work through final inspection. The one thing that makes our Dvele work here different is slab reality: older garage slabs off the alley in San Bernardino’s numbered-street neighborhoods were often poured thin and unpermitted, so we evaluate and re-pour before a panel ever lands. Our crews know Dvele’s panelized SIP system inside out, and we know San Bernardino’s 1940s-1970s housing stock just as well.

Why San Bernardino Residents Choose Us for Dvele Service

Most contractors in San Bernardino have never set a Dvele wall cassette. We have. Neil Bradshaw has spent well over a decade building ADUs in Southern California, and his crews work with Dvele’s structural-insulated-panel system regularly enough to know where factory tolerances meet field reality. That matters when you’re dropping a prefab unit onto a 1950s San Bernardino lot.

We’re not a Dvele dealership. We’re an independent builder who works across multiple prefab brands, so when we tell you a Dvele panelized ADU is the right fit for your San Bernardino property, it’s because the lot, budget, and timeline support it, not because we have one in stock. Know what you’re building before you break ground. We source genuine Dvele panels, connectors, and flashing kits for structural and envelope work, and quality aftermarket fixtures for MEP connections that pass Title 24 and San Bernardino inspection. One contractor from foundation to finished kitchen.

Common Dvele ADU Problems We Solve in San Bernardino

Here’s what actually goes wrong with Dvele units in San Bernardino, and what we do about it:

  • Factory panel tolerances that don’t match a garage conversion tie-in. Dvele’s panel system expects a level, engineered foundation. A thin 1950s alley slab in the numbered-street grid isn’t that. We evaluate the slab first, pour a new engineered pad when needed, and re-stub the factory MEP chase accordingly.
  • SIP wall and roof cassettes compromised during install handling. Inland Empire heat is brutal. On 100F+ summer days, sealant curing between panels can open seams if the crane set and staging aren’t sequenced right. Our crews adjust installation timing and sealing methods for San Bernardino’s semi-arid climate.
  • MEP chases stubbed to Dvele’s standard layout that don’t line up with a 1940s panel or plumbing lateral. The factory assumes a modern rough-in. San Bernardino’s postwar stucco homes rarely have one. We field-rework the chase connections before inspection so your ADU actually passes.
  • Roof-to-wall flashing that assumes a cooler coastal climate. San Bernardino gets intense summer sun and Santa Ana wind uplift. Dvele’s standard flashing details need added shading and wind detailing here, or seams open within a season or two.
  • Heat-related cooling load problems. Dvele’s SIP envelope is efficient, but San Bernardino regularly hits 100F+. If the unit’s Title 24 energy calcs weren’t run for this specific climate zone, cooling costs climb. We verify and adjust shading, glazing, and HVAC sizing before final.

Dvele Service in San Bernardino: What Local Conditions Mean for Your Equipment

San Bernardino’s ADU market is dominated by converting and expanding the city’s huge stock of mid-century single-story stucco homes and detached garages. Because lots are wide and flat in the older grid neighborhoods, most ADUs here are true detached backyard builds or garage conversions rather than tight side-yard infill. That’s actually good news for Dvele’s prefab drop-in model: a crane can typically access the backyard from the street or alley without threading between houses. But the slab question comes first, every time. Older garage slabs off the alley in the numbered-street neighborhoods near downtown were frequently poured thin and unpermitted. Dvele’s panel system needs a level, engineered foundation with proper anchor points. So before we quote a Dvele install in San Bernardino, we check what’s actually underfoot. On one numbered-street lot off the alley near downtown, we set a Dvele panelized single-story ADU in the backyard, but the existing garage slab was too thin and unpermitted to host the utility pad, so we poured a new engineered slab and re-stubbed the factory MEP chase to meet the 1940s service panel and plumbing lateral we upgraded. We then re-flashed and shaded the roof-to-wall seams after a Santa Ana wind event tested the assembly, and the unit passed Title 24 and final inspection. That’s the difference between a drop-in that works and one that fights the site.

Dvele Models & Products We Service in San Bernardino

We service the full Dvele range in San Bernardino: the prefab single-story ADU with SIP wall and roof cassettes, the two-story modular ADU with factory-installed mechanical core, and panelized custom or modified floorplan ADUs built to homeowner spec. For structural and envelope components like panels, connectors, and flashing, we source genuine Dvele replacement parts, never generic substitutes. For MEP connections and interior finishes, we use quality aftermarket fixtures that pass Title 24 and local San Bernardino inspection. We repair and re-seal a Dvele envelope when the issue is install-related. We only recommend replacement when a panel or module has structural damage. That keeps your cost down and your warranty intact.

Dvele Service Pricing in San Bernardino

Dvele ADU service in San Bernardino costs what the site demands. A simple tie-in repair or re-flash runs less than a new engineered slab and MEP re-stub. Here’s what to expect:

  • Slab evaluation: $300 to $600, depending on access and testing depth.
  • New engineered slab pour (when needed): $8,000 to $18,000 for a typical San Bernardino backyard ADU footprint.
  • MEP re-stub and chase correction: $2,500 to $7,000, depending on how far the factory layout is from your 1940s-1970s panel and plumbing lateral.
  • Envelope repair and re-sealing: $1,800 to $5,500 for seam, flashing, and shading corrections after Santa Ana wind or summer heat exposure.
  • Full Dvele install (labor only, unit supplied by Dvele): $85,000 to $160,000, including foundation, crane set, MEP tie-in, and Title 24 compliance.

FAQs – Dvele ADU in San Bernardino

Does Dvele’s prefab panel system work with a San Bernardino garage conversion?

Sometimes, but only after the slab is verified. Many older San Bernardino garage slabs off the alley were poured thin and unpermitted, so we evaluate and often pour a new engineered pad before a Dvele panel can land. Call (866) 403-9834 for a slab assessment, free with your estimate.

How do you handle Dvele’s factory MEP layout when my San Bernardino home has a 1950s panel?

We field-rework the factory MEP chases to match your existing service panel, plumbing lateral, and gas run. That means opening the chase, re-stubbing, and getting it inspected before drywall. Call (866) 403-9834 for an exact quote, estimates are free.

Will a Dvele panelized ADU meet Title 24 in San Bernardino’s hot climate?

Yes, but only if the energy calcs are run for San Bernardino’s specific climate zone, not a coastal default. We verify glazing, shading, and HVAC sizing before final inspection. Call (866) 403-9834 to talk through your specific site.

Can you install a Dvele ADU on a foothill parcel near the San Bernardino Mountains?

Yes, but foothill parcels bring different wind and fire-zone considerations than the valley floor. We adjust flashing, anchoring, and defensible-space detailing for mountain-adjacent San Bernardino sites. Call (866) 403-9834 and we’ll walk the site with you.

Are you authorized by Dvele?

No. We’re an independent Dvele service provider. That means we can tell you honestly when a Dvele unit is the right call for your San Bernardino lot, and when another approach makes more sense. Call (866) 403-9834 for straight answers.
