Dvele Garage Conversion Contractor in San Diego: What to Know First
We convert Dvele homes and Dvele garages into livable space across San Diego, and we do it as an independent Dvele service provider, not as a factory-authorized shop. That distinction matters because we’re free to tell you exactly what’s happening with your structure and what it will cost, without a corporate script. A typical Dvele garage conversion in San Diego runs from $85,000 to $190,000 depending on square footage, finish level, and whether you’re adding plumbing. You’ll get a written price before any work starts, and the whole job is covered by our 365-Day Done Right Promise.
This page is for Dvele owners in neighborhoods like Kensington, North Park, Mission Hills, Point Loma, and Balboa Park who are weighing a garage conversion and want straight answers. If that’s you, call (858) 988-6447 and you’ll reach a live person who can talk through your specific project.
How Dvele Products Fail – and How We Fix Them
Dvele builds a factory-made structural shell, which means most of what goes wrong in a garage conversion isn’t the framing or the walls. It’s the integration points where the factory shell meets the site-built foundation, the utilities, and the San Diego weather. Here’s what we actually see on Dvele jobs in this city.
- Foundation-to-shell water intrusion on Dvele’s detached garage models. Dvele shells are sealed at the factory, but the seam where the steel frame bolts to a site-poured concrete slab is only as good as the flashing and sealant the original installer used. In Point Loma and Mission Hills, where fog and marine air sit on structures for hours each morning, we regularly find that seam opened up and wicking water into the wall assembly. The fix isn’t caulk. We pull the base trim, inspect the sill gasket, replace it with a marine-grade seal, and re-flash before any interior work begins. Skipping this step means hiding a slow leak behind new drywall.
- Electrical panel sizing on early Dvele units. The first generation of Dvele ADUs and garage shells shipped with 100-amp panels, which was fine for a workshop or storage. But a garage conversion with a kitchenette, mini-split, washer/dryer, and EV charging pulls more than that panel can safely deliver. We’ve seen breakers trip during normal afternoon loads in San Diego’s warmer inland neighborhoods like Normal Heights and City Heights. Before we design the conversion, we verify the panel rating, then size the new circuits off a real load calculation, not a guess. That’s the difference between a garage apartment that runs clean and one that buzzes and browns out on a 90-degree day.
- Dvele’s roof-to-wall connection at the parapet. On several Dvele garage and ADU configurations, the low-slope roof drains to a parapet edge, and the factory lap detail at that parapet is the first place we see cracking after a few San Diego summers. The UV here is brutal in inland areas, and the original sealant loses flexibility. We open that lap, replace the sealant with a UV-stable product, and add a secondary reglet so water can’t pool against the seam. It’s a small detail that prevents a whole ceiling replacement later.
- Window and door flashing when Dvele shells are used as garage-to-living conversions. The original garage door opening gets infilled, and if that infill wall is site-built, the transition from the Dvele shell to the new wall is only as dry as the flashing. We’ve fixed jobs where another contractor framed the infill correctly but flashed it like a standard residential wall, and water found the Dvele panel seams within a season. On our conversions we treat that infill-to-shell transition as its own waterproofing detail, with peel-and-stick flashing lapped onto the Dvele panel and a drained sill at the bottom.
- Interior moisture from the slab when adding habitable rooms. Older garages in San Diego often sit on slabs without a proper vapor barrier, and Dvele shells were sometimes placed on existing slabs rather than new pours. When you add flooring, drywall, and a bed, the moisture that used to evaporate into open garage air now gets trapped under the floor. We check the slab’s moisture emission rate before we specify any flooring or wall assembly. If it’s high, we recommend a moisture barrier or a different assembly before you spend money on finishes that will warp or smell musty within a year.
Our Dvele Garage Conversion Contractor Process
Here’s how a Dvele garage conversion goes with us, from the first call to the day we hand you the keys.
- 1
Call and walk-through. You reach a live person when you call (858) 988-6447. We schedule a walk-through of your Dvele garage and talk about what you want: a bedroom, a full ADU, a home office, an apartment for a family member.
- 2
Site and shell inspection. We check the foundation seam, the parapet, the panel, the slab moisture, and the existing Dvele shell condition. We document what’s sound and what needs work before any conversion begins.
- 3
Written line-item price. You get a written price before any tools come off the truck. Not an estimate. A price. Every line item is explained, and if you want to adjust scope, we adjust the number in writing before the work changes.
- 4
Permitting and build. We pull permits for the conversion through the City of San Diego, and our crew works in phases that keep your home protected. Shoe covers and drop cloths go down on every visit. We use pet-safe products where there’s a choice. If you have kids, we work around school drop-off and nap schedules where we can, and we keep noise near bedrooms to reasonable hours.
- 5
Inspection and sign-off. We walk the finished space with you, run every system, and fix anything that’s not right on the spot. Then we send you a photo of the clean-up before the crew leaves.
- 6
365-Day Done Right Promise. If anything we built isn’t done right within the first year, we make it right. That’s in writing, and it covers the entire conversion.
What Dvele Garage Conversion Contractor Costs in San Diego

Garage conversion pricing in San Diego depends on what you’re converting and how far the existing shell needs to go. Here’s what we tell Dvele owners to expect, so you can plan before you call us.
| Project Scope | Typical Price Range in San Diego |
|---|---|
| Dvele garage to bedroom (no plumbing) | $85,000 – $120,000 |
| Dvele garage to studio ADU with kitchenette and bath | $140,000 – $190,000 |
| Dvele detached garage conversion with full one-bedroom layout | $175,000 – $250,000+ |
| Water damage repair before conversion (foundation seam, parapet, or flashing) | $4,000 – $18,000 depending on scope |
| Electrical panel upgrade if needed | $3,500 – $7,500 |
What moves the price: whether you’re adding plumbing, the condition of the existing slab, whether the panel needs an upgrade, and how much of the original Dvele shell needs remediation before we can build. We’ve done jobs where the shell was clean and the conversion went straight in, and jobs where we spent two weeks repairing water intrusion before we could frame a single interior wall.
The number you get from us isn’t a starting point. It’s the number you pay. Call (858) 988-6447 for a free estimate with a written price, and you’ll know exactly where you stand before you commit.
Why San Diego Homeowners Call Seedling ADU San Diego for Dvele Work
We built our reputation in San Diego on one thing: certainty. Homeowners with kids and pets don’t want a crew that shows up late, leaves the front door open, and surprises them with a change order. They want to know who’s in their house and what it will cost to finish.
Our technicians are background-checked and wear uniforms, so you always know who belongs on your property. Every visit includes shoe covers and drop cloths inside the home, and we send a photo of the clean-up before we leave. If you call us during a build, a live person answers. No voicemail trees. No callback in three days.
We also work with other major ADU brands including Abodu and Cover, plus Boxabl, Mighty Buildings, Plant Prefab, and James Hardie materials. That matters if you’re deciding between a Dvele conversion and another route. We’re not married to one factory’s product. We’ll tell you honestly what works on your lot, and what doesn’t.
Ben Ortega leads our San Diego crew. He grew up in East Los Angeles, learned the building trades at Los Angeles Trade-Technical College, and spent the better part of two decades doing residential construction up and down the California coast. For the last several years, he and the crew have focused entirely on ADU work in San Diego, from Kensington bungalows to newer builds near Balboa Park. He walks every homeowner through every cost line before a single tool comes out of the truck, and he’s known for leaving a jobsite cleaner than he found it. His rule on every project: know the number before the shovel moves.
FAQs

It can, depending on the original warranty terms and how the conversion affects the shell. As an independent Dvele service provider, we review your warranty documentation before we design the conversion, and we flag any work that could impact coverage. In many cases, the shell warranty stays intact as long as we’re not modifying structural components. We’ll tell you exactly what’s at risk in writing before you decide, so you’re never surprised later.
Most Dvele garage conversions we do in San Diego take between 10 and 16 weeks from permit approval to final inspection. The biggest variable is the city’s permit review timeline, which can run four to eight weeks depending on the scope and current volume at the Development Services Department. If we find water damage or slab issues during the inspection phase, that adds time before the finish work starts. We give you a realistic schedule up front and update it in writing if anything shifts, so you’re never left guessing when the crew will finish.
Yes, and with San Diego’s marine layer and UV exposure, we often do. We inspect the foundation seam, parapet, window flashing, and slab moisture before any conversion starts. If we find intrusion, we repair it first and document the fix with photos. That remediation is included in your written price, not added as a surprise line item after the walls are open.
No. For the shell itself, we recommend factory-specified fasteners and sealants where the shell needs repair, because those components were engineered for that panel system. For everything inside the conversion, walls, flooring, electrical, plumbing, HVAC, we use quality trade materials that meet or exceed San Diego building code, and we choose them for your climate and your budget. We’ll tell you when a Dvele-specific product is worth the cost and when a standard product performs just as well.
Yes, we pull all required permits through the City of San Diego and coordinate all inspections. Dvele structures sometimes require additional documentation because they’re factory-built, and we handle that paperwork as part of the job. If you’d like help navigating the permit process before you commit, call (858) 988-6447 and we’ll walk through your specific project.
