Dvele ADU in Fremont, CA | Lodgewick ADU San Jose
We provide independent Dvele ADU service across Fremont, from Mission San Jose to Niles and every neighborhood between. What separates our Dvele work here is that we’ve spent years matching factory-built Dvele panels and mechanical systems to Fremont’s particular housing stock: 1950s-to-1970s ranch homes on flat slabs with aging electrical service. If your Dvele ADU needs repair, a panel upgrade, or seismic correction, call (669) 266-4319 for a free estimate.
Lodgewick ADU San Jose is an independent Dvele service provider. We are not manufacturer-affiliated or authorized by Dvele. We know these buildings because we’ve fixed the problems that show up years after the crane leaves. For deeper background on the brand, see our Dvele sales & service page.
Why Fremont Residents Choose Us for Dvele Service
Dvele ADUs arrive as precision-fabricated modules: panelized walls, roof cassettes, and mechanical cores built in a factory, then craned onto a Fremont lot. That precision is the product’s strength. It’s also the source of most service calls we see, because a factory tolerance of 1/8 inch meets a 1963 slab that has shifted half an inch over sixty years. The two don’t always agree.
Russ Delmar, our owner, trained in building technology at Los Angeles Trade-Technical College and has spent over a decade focused on accessory dwelling units, meaning a second living space added to your existing property. He’s the person homeowners call when a previous contractor left them with a half-finished Dvele install and a utility chase that was never properly flashed. Straightening out that kind of work is quietly what we’re known for across Fremont service area neighborhoods.
We stock Dvele-specific components locally, including their proprietary window packs and ERV filters, because off-the-shelf substitutes rarely match the panel tolerances. That means a Fremont homeowner isn’t waiting a week for a part to ship from the factory.
Common Dvele ADU Problems We Solve in Fremont
These are the issues we see repeatedly on Dvele units in Fremont. Each one is tied to something specific about how these buildings age here.
- Condensation and mildew at the roof-to-stucco transition. Fremont’s mild wet winters push moisture into the marriage line between Dvele’s panelized roof cassettes and older stucco walls. If the original install didn’t use Dvele’s factory flashing, interior condensation follows. We see this on ranch homes throughout Glenmoor and Brookvale.
- Seismic drift and cracking at the utility chase. Fremont sits near the Hayward Fault. When a Dvele module is set on an existing 1960s slab without a new perimeter foundation, even small tremors cause drift. The utility chase is usually the first place cracks appear.
- Main panel overload and tripping breakers. Many Fremont garages still have original 60-amp panels. Dvele’s factory-installed ERV and heat pump draw more than that old service can safely supply. The fix is a 200-amp upgrade before the ADU can operate reliably.
- Differential settlement at the floor transition. Fremont’s expansive clay soils move with the seasons. Dvele’s prefabricated floor cassette settles differently than the original house, producing a 1/4-inch step at the doorway and binding entry doors.
- Crane-access and easement complications on rear-lot ADUs. Fremont’s 1957 zoning code wrote rear yard access easements into most ranch lots. When a Dvele module is set behind the garage, that old easement line often dictates the exact setback and needs a lot-line adjustment before the crane can even position.
Dvele Service in Fremont: What Local Conditions Mean for Your Equipment
Fremont’s 1957 zoning code required every single-family home to have a two-car garage with a separate rear yard access easement. Walk any street of original ranch homes in the Irvington district or along Peralta Boulevard, and you can still see that easement etched into the property lines. For Dvele ADU owners, that decades-old rule has a direct consequence: when a module is placed behind the original garage, the old easement line frequently dictates the exact setback. In practice, that means a lot-line adjustment before the module can be legally craned into place. We handle that permitting work as part of the service, because skipping it creates a title problem that surfaces when you sell.
This is also why so many Fremont Dvele ADUs are attached conversions or our Garage Conversion Contractor in Fremont garage-adjacent additions rather than fully detached units. The flat, rectangular lots that once made Fremont an easy place to build tract housing now constrain where a prefabricated module can sit. We’ve learned to read those lot lines on a site visit, not after a permit rejection.
Dvele Models & Products We Service in Fremont
We service the full Dvele lineup: the Dvele ONE studio, the Dvele DUO two-bedroom, the Dvele ADU Series, and Dvele Custom Series homes. Most Fremont service calls come from ADU Series and ONE units set as rear yard additions or Fremont Home Addition Contractor projects.
For structural components, we use Dvele’s factory-specified parts wherever possible. Their proprietary window packs and ERV filters are the two most common replacements we handle, and we keep them stocked for fast Fremont turnaround. For non-structural items like water heaters or disconnects, we install equivalent UL-listed parts after confirming fit. When a Dvele module has structural damage or major delamination, we advise replacing that module rather than attempting a site repair that would void the assembly’s performance warranty.

FAQs – Dvele ADU in Fremont
Why does my Fremont Dvele ADU need a 200-amp panel upgrade when the factory says it only draws 60 amps?
That factory 60-amp figure is the ADU’s continuous draw under normal conditions. The issue in Fremont is the existing home’s panel, which on many 1950s-70s ranch houses is already a 60-amp service with no headroom. When the Dvele ERV and heat pump start together, the combined load trips the main. Upgrading to 200 amps gives the module the startup headroom the original service never had. Call (669) 266-4319 and we’ll check your panel rating before quoting.
How do you handle the Hayward Fault seismic requirements for a Dvele ADU on my Fremont slab?
We install perimeter anchorage that ties the Dvele module to a new concrete footing or to existing slab edges that meet current shear standards. On 1960s slabs, that often means a partial perimeter foundation rather than relying on the original slab. The utility chase gets specific attention, since that’s the first point to crack when a module drifts.
Can you place a Dvele ADU behind my Fremont garage without a separate rear easement?
It depends on your lot. Fremont’s 1957 zoning code required rear yard access easements on many original ranch lots. If yours has one, the easement line can dictate the exact setback, and a lot-line adjustment may be required before the module is set. We check the title and easement records during the estimate, so you’ll know early whether it’s a hurdle.
Why does my Dvele ADU show condensation on the ceiling near the original house wall during Fremont winters?
That condensation is almost always moisture migration at the marriage line between the Dvele roof cassette and the existing stucco wall. Fremont’s wet winters drive moisture into that seam, and if the factory flashing wasn’t installed correctly, or wasn’t installed at all, condensation and mildew follow. We reseal the transition with Dvele’s factory flashing and verify the ERV is balanced to clear the residual moisture. Call (669) 266-4319 for a diagnostic visit.
Do you repair Dvele ADUs that were installed by a different contractor, or only ones you set?
We repair Dvele ADUs regardless of who installed them. Most of our Fremont service calls are on units set by other contractors. We assess the installation, identify what’s failing, and quote the repair in writing before any work starts.
