Dvele ADU in San Bernardino, CA | Sunstone ADU Builders
We install, finish, and service Dvele prefab and modular ADUs across San Bernardino. We’re an independent Dvele service provider, which means we adapt the factory platform to what this city’s older housing stock actually throws at it: 60-amp panels, shallow sewer laterals, and wildfire-interface code requirements. The result is a Dvele ADU that survives San Bernardino’s 100°F summers and clears inspection without surprises. Call (855) 949-1913 for a free estimate on your Dvele project.
Why San Bernardino Residents Choose Us for Dvele Service
Our practice is built around Dvele’s panelized and modular construction methods, and we’ve set enough of their factory-built wall, floor, and roof assemblies on San Bernardino lots to know how they behave once they meet local soil, sun, and aging utility services. We’re not guessing. Nate Holloway, our owner, spent the better part of two decades on residential construction across Orange County before focusing exclusively on ADUs, and that background shapes how we approach every Dvele install here: check the existing infrastructure first, then size the module to what the site can actually support. The Dvele sales & service work we do spans both the factory shell and the site-side connections that make it operational.
San Bernardino homeowners also get something a generic Dvele dealer won’t give them: a straight answer. If a Dvele unit pencils out on your lot, we’ll say so. If upgrading your panel, sewer lateral, and exterior fire detailing will add $30,000 before the module ever lands, we’ll tell you that too, before you sign anything. Call (855) 949-1913 and we’ll walk the site with you.
Common Dvele ADU Problems We Solve in San Bernardino
- Factory electrical chases that overload a 60-amp service. Dvele’s factory-set electrical chases are engineered for modern 200-amp feeds. But many San Bernardino homes built in the 1950s still run on 60-amp panels. The module’s load calculation exposes the gap immediately, and the unit can’t be energized until the service is upgraded. We handle the panel replacement and the new feeder run as part of the install.
- Door and window racking from uneven site pads. Dvele’s panelized envelope only performs correctly on a dead-level foundation. In the older, sloped lots around ZIP 92404 and 92405, rushed foundation prep causes settling, and we’ve seen door and window frames rack within the first year. We don’t rush the pad, and we check elevation before the crane ever arrives.
- West-facing cooling struggles during San Bernardino summers. San Bernardino regularly tops 100°F in July and August. A Dvele unit with unshaded west-facing glazing soaks up that afternoon sun, and the factory cooling spec gets overwhelmed. We add shading, verify the Title 24 envelope details, and confirm the insulation installation before sign-off.
- Fire-interface requirements at the mountain base. Homes near the San Bernardino Mountains fall inside wildfire-interface zones. Dvele’s standard exterior assemblies may not pass local inspection without fire-rated siding, ember-resistant vents, and Class A roofing. Omissions here stall the final inspection and mean rework.
- Shallow sewer laterals that complicate Dvele connections. Many pre-1970 San Bernardino homes have shallow sewer lines that can’t handle a new dwelling unit’s flow without upgrades. We coordinate the sewer lateral replacement so the Dvele module’s plumbing ties in cleanly and passes on the first walk-through.
Dvele Service in San Bernardino: What Local Conditions Mean for Your Equipment
Here’s the detail that separates a Dvele install in San Bernardino from one in, say, Redlands or Ontario. In the older tracts around ZIPs 92404 and 92405, the 1950s-era electrical service is so consistently just 60 amps that a Dvele module’s cooling and appliance load can’t be energized until the panel is upgraded to 200 amps. This isn’t a rare edge case. It’s the default condition. In the narrow lots along corridors like Base Line and Dvele in Highland Avenue, homeowners commonly convert their detached garages into ADUs, and those garage-side services are almost always the original 60-amp panels. So we treat the electrical service upgrade as a precondition of the Dvele install, not an optional add-on. If you own a stucco tract house from that era and you’re budgeting for a Dvele, know that your panel upgrade is part of the real cost, and it’s better to plan for it before the module is ordered than to discover it during energization.
Dvele Models & Products We Service in San Bernardino
We service the full Dvele platform across Dvele in Rialto and San Bernardino: the detached prefab studio and 1-bed configurations, the 2-bed modular ADU, panelized custom shells with factory-set mechanical and electrical chases, and above-garage / two-story modular units. For structural and envelope components, we source Dvele factory parts and connection hardware to preserve the platform’s engineering. For site-side utilities, fixtures, and finishes, we use quality aftermarket parts where the factory spec allows. Because we know which Dvele models are common in this region, we keep the site-side connection hardware that slows down San Bernardino projects on hand or quickly obtainable, cutting the wait between panel upgrade and final energization.
Dvele Service Pricing in San Bernardino
Dvele ADU service pricing in San Bernardino depends on three things: which model you’re installing, what your existing infrastructure looks like, and whether fire-interface upgrades are required. A detached Dvele 1-bed module on a lot with a modern panel and clear sewer access lands near the lower end of the range. A 2-bed modular unit on a 1950s lot with a 60-amp panel, shallow sewer lateral, and wildfire-zone exterior requirements will push toward the upper end, because the panel upgrade, sewer lateral replacement, and fire-rated cladding are site costs the module price doesn’t show you. Our free estimate includes a site walk, a look at your panel and sewer condition, and a written line-by-line breakdown so you’re not surprised later. Call (855) 949-1913 for exact pricing on your San Bernardino lot.

FAQs – Dvele ADU in San Bernardino
Yes, but not without a service upgrade. A Dvele module with air conditioning and appliances won’t energize on 60 amps. You’ll need the panel upgraded to 200 amps and a new feeder run to the unit’s factory chase. We do that work as part of the install. Call (855) 949-1913 for a site assessment.
Often not out of the box. Properties in wildfire-interface zones require fire-rated siding, ember-resistant vents, and Class A roofing. Dvele’s standard exterior assemblies may need these added before inspection. We spec and install the required upgrades so the unit passes.
It can be. Dvele makes above-garage and two-story modular units designed for exactly this situation. The constraint is usually the existing garage’s foundation and the 60-amp service feeding it. We assess both before recommending the model that fits. Call (855) 949-1913 and we’ll measure.
Many pre-1970 San Bernardino ADU Builders encounter homes with shallow sewer laterals and older gas lines that need updating before a new dwelling unit can connect. We coordinate the sewer lateral replacement and gas line extension as part of the Dvele install, so the module’s plumbing and mechanicals tie in cleanly and pass inspection the first time.
No. We’re an independent Dvele service provider, not manufacturer-affiliated or authorized. That independence means we assess the platform honestly for your San Bernardino site and adapt it to local code and infrastructure, rather than pushing a factory script.
