Dvele ADU Builders in San Francisco: What to Know First
Independent Dvele ADU builders in San Francisco typically charge $85 – $145 per hour for diagnostic and repair work, with most Dvele-specific fixes landing between $900 and $4,200 depending on what’s failed. We’re Lodgewick ADU San Francisco, and we’ve handled Dvele builds and repairs across the city for the better part of a decade. We are not affiliated with or authorized by Dvele. We’re an independent Dvele service provider, which means we tell you the truth about your module without a manufacturer script. If you own a Dvele unit and something isn’t right, call (707) 760-0502 and we’ll walk you through what we’re seeing.
This page is for San Francisco homeowners who bought or inherited a Dvele prefab ADU and now need someone who actually knows how these units go together. Not a general contractor who’ll figure it out on your dime.
How Dvele Products Fail – and How We Fix Them
Dvele builds steel-framed, panelized modules with the mechanical and electrical systems pre-installed at their factory in Loma Linda. That’s smart manufacturing. But San Francisco’s fog, salt air, and Victorian-era lot constraints create failure patterns you won’t find in Dvele’s marketing materials. Here’s what we actually see:
- Dvele Origin Series – envelope seal separation at module joints. The Origin line’s multi-module design means the joint between modules gets caulked and taped at the factory, then re-sealed on site. In San Francisco’s wet winters, that seam is the first place moisture finds a way in. We pull the old sealant, prep the joint properly, and re-seal with a marine-grade product rated for our coastal climate. It’s a three-day fix most of the time, and it’s the single most common Dvele repair we do.
- Dvele IQ system – moisture sensor false positives near the coast. Dvele’s built-in monitoring system uses humidity sensors in wall cavities. Within a mile of Ocean Beach or in the avenues, fog intrusion can trip those sensors even when there’s no actual leak. We verify with thermal imaging and a borescope before anyone opens a wall. No point cutting into a module for a sensor that reads high because Karl the Fog lives in your wall cavity.
- Dvele Alto and Luna series – HVAC condensate routing that doesn’t match reality. The factory routes condensate assuming a level pad. Half the San Francisco lots we work on have a 2 – 6% grade somewhere. Gravity doesn’t care what the drawing says. We re-route the condensate line so it actually drains, then test it with a full pan cycle. It’s a small fix that prevents a big mold problem.
- Dvele Signature line – window flashing that wasn’t built for San Francisco wind-driven rain. The factory flashing works fine for most climates. In the Sunset and Richmond districts, rain comes sideways off the Pacific. We add a peel-and-stick membrane under the window sills and re-flash the heads. It’s the difference between a 10-year window and a 25-year window here.
- Dvele plumbing – SharkBite-style push fittings that loosen after transport. The factory uses push-to-connect fittings for speed. By the time a module rides up I-5 and gets craned over a San Francisco fence, some of those connections have micro-loosened. We pressure-test every accessible connection on any Dvele repair, because a slow drip inside a steel-framed wall is a long-term structural problem, not just a water stain.
Our Dvele ADU Builders Process
When you call Lodgewick ADU San Francisco for Dvele work, here’s how it goes:
- 1
Call and talk to a person. You call (707) 760-0502, and someone answers. Russ Delmar picks up on the second ring most days. You describe what’s happening in plain terms. We listen.
- 2
Site walk and diagnostics. Russ or one of our senior techs walks your Dvele unit before quoting anything. Thermal imaging, borescope if needed, and a check of the IQ system logs. We identify the failing component, not the symptom.
- 3
Written price, itemized. You get a line-item quote before any work starts. Parts, labor, timeline, what we’ll do and what we won’t. No price changes at the door. Ever.
- 4
Parts decision, explained. We tell you where OEM Dvele parts make sense and where a quality aftermarket part does the same job for less. You decide. We document everything so any remaining factory warranty stays intact where it can.
- 5
Repair, test, cleanup. We fix it, test it thoroughly, and leave the job site cleaner than we found it. That’s The Kingswell Way.
- 6
Written guarantee. Before we leave, you get our 365-Day Done Right Promise in writing. If the work isn’t right within a year, we come back and make it right. No invoice, no argument.

Why San Francisco Homeowners Call Lodgewick ADU San Francisco for Dvele Work
We started in 2010 as part of the Kingswell family of home-service companies, and we’ve spent years earning a reputation in San Francisco neighborhoods from the Sunset to Bernal Heights. Russ grew up in the San Gabriel Valley, studied construction technology at LA Trade-Tech, and spent years on foundation work and finish carpentry before ADUs became the focus. He’s walked more San Francisco lots than most people have walked city blocks, including projects near Dolores Park where Victorian lot lines make every build its own puzzle.
The Kingswell Guarantee applies to every Dvele job we touch: written price first, real arrival window, clean job site, written guarantee. We also service Abodu and Cover units, which means when a Dvele part is on backorder, we can often cross-reference what works from other prefab systems and keep your project moving. Tell us what the space needs to do, and we’ll figure out how to build it right.
FAQs

In most cases, yes. Independent service work doesn’t void a Dvele warranty automatically, especially for items like flashing, sealing, and plumbing connections that fall outside factory coverage anyway. We document every repair so you have a record if a future warranty claim comes up. Call (707) 760-0502 if you’re unsure and we’ll tell you what we’d touch and what we’d leave alone.
Most Dvele repair calls get a site walk within 3 – 5 business days. If you’ve got water actively coming through a module joint, tell us when you call and we’ll prioritize it. A live person answers 24/7 at (707) 760-0502.
It depends on the part. For structural components and IQ system sensors, we use OEM Dvele parts. For flashing, sealants, condensate lines, and plumbing fittings, we often use better-than-OEM products that hold up longer in San Francisco’s coastal climate. We show you the difference and the price on every quote.
If the steel frame and factory envelope are sound, repair almost always wins. We’ve seen Dvele units with a bad module seam and a misrouted condensate line that needed $2,800 in work look brand new afterward. Replacement only makes sense if there’s structural rust or fire damage. We’ll tell you straight which side of that line your unit sits on.
A detached Dvele ADU in San Francisco typically runs $280,000 – $450,000 all-in, including site prep, crane work, utility hookups, permits, and finishing. Garage conversions and smaller studio units land lower. Call (707) 760-0502 for a written line-item estimate on your specific lot.
No. We give you a written price before any work begins, and that’s the price. If we find something hidden, we stop, show you, and get your sign-off before spending another dollar. The 365-Day Done Right Promise means if what we fixed fails within a year, we come back free.
