If you own a Dvele home and want to know what your garage can become, call (669) 266-4319 and we’ll walk you through it.
This page is for San Jose homeowners who already own a Dvele home, or are thinking about one, and want to convert their garage into a bedroom, apartment, or full ADU. We’re an independent Dvele service provider, not a factory-authorized contractor, which means we answer to you, not to a warranty department.
How Dvele Products Fail – and How We Fix Them
- Dvele’s steel frame and panel system makes garage conversions structurally straightforward, but the existing slab is often the weak point. Dvele homes built on slabs poured for a garage, not living space, regularly lack the vapor barrier and insulation needed for a conditioned room. We’ve opened up Dvele garages in Willow Glen and found moisture wicking up through the slab because the original pour didn’t include an underslab vapor retarder. Our fix is a proper moisture barrier, insulation, and finished flooring rated for slab contact, not just a coat of epoxy.
- Dvele’s wall panel joints can show hairline cracking at the garage-to-house transition. The factory-made panels are precise, but San Jose’s clay soil expands and contracts with our wet winters and dry summers. That movement concentrates at the connection points. We reinforce those transitions before drywall goes up, so you’re not chasing cracks in the finish.
- Dvele’s integrated electrical and plumbing chases are sized for the original floor plan, and garage conversions push their capacity. Adding a bathroom or a kitchenette to a space never designed for it means the existing chases may be too small for sanitary lines or additional circuits. We don’t jury-rig these; we run new penetrations through the panels properly and close them with the same sealing detail Dvele uses, so the building envelope stays intact.
- Dvele’s windows and doors are high-quality, but garage door openings need real structural header work to convert to wall sections. The original garage door opening wasn’t framed for a standard window and wall infill. We install the proper header, match the existing panel system where we can, and weather-seal the transition like it’s part of the original build.
- The Dvele HVAC system in many San Jose homes is zoned for the main house, not for a converted garage. Extending the existing system to a garage conversion usually creates uneven temperatures and humidity issues. We size a dedicated mini-split or extend ductwork with a proper Manual J calculation, not a guess. A converted garage that’s always ten degrees off isn’t a conversion, it’s a storage room with a couch.

What Dvele Garage Conversion Contractor Costs in San Jose
Garage conversions on Dvele homes in San Jose typically land in these ranges:
- Attached garage to bedroom or office: $95,000 – $130,000 – simpler utility runs, existing wall shared with the house.
- Attached garage to full ADU with kitchenette and bath: $120,000 – $165,000 – new plumbing, electrical subpanel, and HVAC zoning.
- Detached Dvele garage to apartment: $110,000 – $155,000 – more foundation and envelope work, separate utility trenching.
What moves the price: slab remediation, panel joint reinforcement, HVAC scope, and whether you need a separate electrical service. Permits and inspections are included in our written price; you’ll see them as a line item, not a surprise at the end. Call (669) 266-4319 and we’ll give you a real number for your specific Dvele structure.
Why San Jose Homeowners Call Lodgewick ADU San Jose for Dvele Work
We’re the ADU company of the Kingswell family, and every Dvele garage conversion we take on in San Jose operates under The Kingswell Guarantee: written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every job. If the work fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and you get it in writing before we drive the first nail.
Russ Delmar leads our San Jose crew, and he’s spent more than a decade untangling ADU and garage conversion projects that other contractors left half-finished. He grew up in Los Angeles, trained in building technology at LATTC, and has worked every stage of a build. Homeowners near the Willow Glen corridor know him as the person who says the price before the work and shows up when he says he will.
We also work with Abodu and Cover structures when a Dvele conversion calls for a second unit or a different prefab solution. Knowing multiple systems means we don’t force a Dvele fix where a different approach serves you better.
FAQs
Possibly, depending on the scope and what portions of the original structure you modify. As an independent Dvele service provider, we can’t speak for Dvele’s warranty department, but we document every modification and use panel-compatible sealing and fastening methods so the envelope integrity stays close to factory spec. Call (669) 266-4319 and we’ll review your specific warranty terms with you before anything gets touched.
Most Dvele garage conversions in San Jose run 10 to 16 weeks from permit submission to final inspection, assuming no major slab remediation. San Jose’s permit review time varies, and that’s the part nobody can rush. We’ll tell you the realistic timeline for your project when we give you the written scope.
Yes. Every garage conversion we do in San Jose is permitted, inspected, and built to California residential code. Unpermitted garage conversions cause problems at resale and with insurance. We don’t do them. If a previous contractor started your conversion without permits, we can help straighten that out too.
Yes, and this is a big part of what we do in San Jose. We’ve taken over Dvele projects where the slab was never properly moisture-sealed, the panel joints were cracking, or the permits were stalled. We assess what’s there, write the scope to finish it right, and give you a written price before we touch anything. Tell us what you were promised before, and we’ll tell you what we can actually deliver.
